Baclofen is indicated in-

• spasticity resulting from multiple sclerosis
• flexor spasms and concomitant pain, clonus and muscular rigidity
• skeletal muscle spasm resulting from rheumatic disorders
• spinal cord injuries and other spinal cord diseases
• cerebrovascular accidents or neoplastic or degenerative brain disease

Centrally acting Skeletal Muscle Relaxants

Baclofen inhibits both monosynaptic and polysynaptic reflexes at the spinal level by stimulating the GABA_B receptors, which inhibits the release of glutamate and aspartate. It may also act at intraspinal sites producing CNS depression. Baclofen also exerts an antinociceptive effect.

Adult & children over 10 years: 5 mg 3 times daily, preferably with or after food, gradually increased; max. 100 mg daily.

Children <10 years: Treatment is usually started with 2.5 mg (2.5 ml) given 4 times daily then raised according to requirement. Daily maintenance dose-

• 12 month-2 years: 10-20 mg (10-20 ml)
• 2 years-6 years: 20-30 mg (20-30 ml)
• 6 years-10 years: 30-60 mg (30-60 ml)

The most common adverse reactions associated with Baclofen are transient drowsiness, daytime sedation, dizziness, weakness and fatigue.

• Central Nervous System: Headache (<10%), insomnia (<10%), and rarely, euphoria, excitement, depression, confusion, hallucinations, paraesthesia, nightmares, muscle pain, tinnitus, slurred speech, co-ordination disorder, tremor, rigidity, dystonia, ataxia, blurred vision, nystagmus, strabismus, miosis, mydriasis, diplopia, dysarthria, epileptic seizures, respiratory depression.
• Cardiovascular: Hypotension (<10%), rare instances of dyspnoea, palpitation, chest pain, syncope.
• Gastrointestinal: Nausea (approximately 10%), constipation (<10%) and rarely, dry mouth, anorexia, taste disorder, abdominal pain, vomiting, diarrhoea and positive test for occult blood in stool.
• Genitourinary: Urinary frequency (<10%) and rarely, enuresis, urinary retention, dysuria, impotence, inability to ejaculate, nocturia, haematuria.
• Other: Instances of rash, pruritus, ankle oedema, excessive perspiration, weight gain, nasal congestion, visual disturbances, hepatic function disorders and paradoxical increase in spasticity. Muscular hypotonia of a degree sufficient to make walking or movement difficult may occur but is usually relieved by readjusting the dosage. For this purpose, the daytime dosage may be reduced and the evening dosage increased.

Baclofen is contraindicated in patients with hypersensitivity to any component of this product.

Pregnancy category B3. Safe use of Baclofen during pregnancy has not been established. Baclofen crosses the placental barrier. Baclofen should only be administered to pregnant women when in the judgement of the physician concludes that the potential benefits outweigh the possible hazards. Baclofen is excreted in breast milk however evidence to date suggests that the quantities are so small that no undesirable effects on the infant would be expected.

Gastric lavage is important in case of severe overdose.

Keep below 30°C temperature, away from light & moisture. Keep out of the reach of children.

Benzodiazepine sedatives

Bromazepam is a powerful psychotropic agent. In lower dosage, it selectively reduces tension and anxiety. In higher dosage, it shows sedative and muscle-relaxant properties. Bromazepam binds to the GABA-A receptor producing a conformational change and potentiating its inhibitory effects. Other neurotransmitters are not influenced.

Standard dosage: Average dosage for outpatient therapy is 1.5-3 mg up to three times daily. Treatment of outpatients should begin with low doses, gradually increasing to the optimum level.

In severe cases, especially in hospital: 6-12 mg 2 or 3 times daily. The overall treatment generally should not be more than 8-12 weeks. In certain cases extension beyond the maximum treatment period may be necessary; if so, it should be taken with re-evaluation of the patient's status with special expertise.

Elderly and debilitated patients: Elderly patients and those with impaired hepatic functions require lower doses.

Children: Bromazepam is usually not indicated in children, but if the physician feels bromazepam treatment is appropriate, then the dose should be adjusted to their low bodyweight (about 0.1-0.3 mg/kg bodyweight)

Bromazepam tablets are for oral administration

Common side-effects include fatigue, drowsiness, muscle weakness, numbed muscle, reduced alertness, confusion, headache, ataxia etc. These phenomena occur predominantly at the start of therapy and usually disappear with prolonged administration. Anterograde amnesia may occur using therapeutic doses.

Bromazepam is contraindicated in patients with known hypersensitivity to bromazepam, severe respiratory insufficiency, severe hepatic insufficiency or sleep apnea syndrome.

The use of benzodiazepines and benzodiazepine like agents may lead to the development of physical and psychological dependence upon these products. This dependence depends on the dose and duration of treatment; it is also greater in predisposed patients with a history of alcohol. Once physical dependence has developed, termination of the treatment will be accompanied by withdrawal symptoms. These may consist of headache, muscle pain, extreme anxiety, tension, confusion and irritability. Since the risk of withdrawal phenomena and rebound phenomena is greater after abrupt discontinuation of the treatment, it is recommended that the dosage be decreased gradually. Bromazepam is not recommended for the primary treatment of sleeplessness caused by psychotic illness. Caution should be exercised while driving cars or using machineries.

If bromazepam is combined with other centrally active drugs, its sedative effects may be enhanced. These drugs are antidepressants, hypnotics, narcotics, antipsychotics, sedatives, antiepileptic drugs, sedative antihistamines and anesthetics. Co-administration of cimetidine may prolong the eliminiation half-life of bromazepam. Concomitant intake of bromazepam with alcohol should be avoided, because the sedative effect of bromazepam may be intensified by alcohol.

The safety of bromazepam during pregnancy has not been established. As bromazepam is excreted in breast milk, use should be avoided during lactation.

Keep in a dry place away from light and heat. Keep out of the reach of children.

Adjunct anti-epileptic drugs, Benzodiazepine hypnotics

Clonazepam exhibits pharmacological properties which are common to benzodiazepines and include anticonvulsive, sedative, muscle relaxing and anxiolytic effects. The central actions of benzodiazepines are mediated through an enhancement of the GABAergic neurotransmission at inhibitory synapses. In the presence of benzodiazepines the affinity of the GABA receptor for the neurotransmitter is enhanced through positive allosteric modulation resulting in an increased action of released GABA on the postsynaptic transmembrane chloride ion flux.

There are also animal data showing an effect of clonazepam on serotonin. Animal data and electroencephalographic investigations in man have shown that clonazepam rapidly suppresses many types of paroxysmal activity including the spike and wave discharge in absences seizures (petit mal), slow spike wave, generalized spike wave, spikes with temporal or other locations as well as irregular spikes and waves. Generalized EEG abnormalities are more regularly suppressed than focal abnormalities. According to these findings clonazepam has beneficial effects in generalized and focal epilepsies.

Oral:

• Adults: The initial dose for adults with seizure disorders should not exceed 1.5 mg/day divided into three doses. Dosage may be increased in increments of 0.5 to 1 mg every 3 days until seizures are adequately controlled or until side effects preclude any further increase. Maintenance dosage must be individualized for each patient depending upon response. Maximum recommended daily dose is 20 mg.

• The initial dose for adults with panic disorder is 0.25 mg given in two divided dose. An increase to the target dose for most patients of 1 mg/day may be made after 3 days.
• Pediatric Patients: In order to minimize drowsiness, the initial dose for infants and children (up to 10 years of age or 30 kg of body weight) should be between 0.01 and 0.03 mg/kg/day but not to exceed 0.05 mg/kg/day given in two or three divided doses.

Injection:

• Infants and children: half of a vial (0.5 mg) by slow IV injection or by IV infusion.

• Adults: 1 vial (1 mg) by slow IV injection or by IV infusion. This dose can be repeated as required (1-4 mg are usually sufficient to reverse the status). In adults, the rate of injection must not exceed 0.25 - 0.5 mg per minute (0.5-1.0 ml of the prepared solution) and a total dose of 10 mg should not be exceeded.

The most frequently occurring side effects of Clonazepam are referable to CNS depression. Experience in treatment of seizures has shown that drowsiness has occurred in approximately 50% of patients and ataxia in approximately 30%. In some cases, these may diminish with time; behavior problems have been noted in approximately 25% of patients. Abnormal eye movements, aphonia, coma, tremor, vertigo, confusion, depression, amnesia, hallucinations, hysteria, increased libido, insomnia, psychosis & palpitations may also occur.

It should not be used in patients with a history of hypersensitivity to benzodiazepines, nor in patients with clinical or biochemical evidence of significant liver disease. It may be used in patients with open angle glaucoma who are receiving appropriate therapy but is contraindicated in acute narrow angle glaucoma.

When used in patients in whom several different types of seizure disorders coexist, Clonazepam may increase the incidence or precipitate the onset of generalized tonic-clonic seizures. This may require the addition of appropriate anticonvulsants or an increase in their dosages. The concomitant use of valproic acid and Clonazepam may produce absence status.

Clonazepam does not appear to alter the pharmacokinetics of phenytoin, carbamazepine or phenobarbital. The effect of Clonazepam on the metabolism of other drugs has not been investigated.

Pregnancy: From preclinical studies it cannot be excluded that clonazepam possesses the possibility of producing congenital malformations. From epidemiological evaluations there is evidence that anticonvulsant drugs act as teratogens. However, it is difficult to determine from published epidemiological reports which drug or combination of drugs is responsible for defects in the newborn. The possibility also exists that other factors e.g. genetic factors or the epileptic condition itself may be more important than drug therapy in leading to birth defects. Under these circumstances, the drug should only be administered to pregnant women if the potential benefits outweigh the risk to the foetus. During pregnancy, Clonazepam may be administered only if there is a compelling indication. Administration of high doses in the last trimester of pregnancy or during labour can cause irregularities in the heartbeat of the unborn child and hypothermia, hypotonia, mild respiratory depression and poor feeding in the neonate. It should be borne in mind that both pregnancy itself and abrupt discontinuation of the medication can cause exacerbation of epilepsy. Withdrawal symptoms in newborn infants have occasionally been reported with benzodiazepines.

Nursing Mothers: Although the active ingredient of Clonazepam has been found to pass into the maternal milk in small amounts only, mothers undergoing treatment with this drug should not breastfeed. If there is a compelling indication for Clonazepam, breastfeeding should be discontinued.

Pediatric Use: In infants and small children Rivotril may cause increased production of saliva and bronchial secretion. Therefore special attention must be paid to maintaining patency of the airways. 

Geriatric Use: Benzodiazepine pharmacologic effects appear to be greater in elderly patients than in younger patients even at similar plasma benzodiazepine concentrations, possibly because of age-related changes in drug–receptor interactions, post-receptor mechanisms and organ function.

Renal Impairment: Renal impairment does not affect the pharmacokinetics of clonazepam. Based on pharmacokinetic criteria, no dose adjustment is required in patients with renal impairment.

Hepatic Impairment: Plasma protein binding of clonazepam in cirrhotic patients is significantly different from that in healthy subjects (free fraction 17.1±1.0% vs 13.9±0.2%). Although the influence of hepatic impairment on clonazepam pharmacokinetics has not been further investigated, experience with another closely related nitrobenzodiazepine (nitrazepam) indicates that clearance of unbound clonazepam might be reduced in liver cirrhosis.

Symptoms: Benzodiazepines commonly cause drowsiness, ataxia, dysarthria and nystagmus. Overdose of Clonazepam is seldom life-threatening if the drug is taken alone, but may lead to areflexia, apnoea, hypotension, cardiorespiratory depression and coma. Coma, if it occurs, usually lasts a few hours but it may be more protracted and cyclical, particularly in elderly patients. Increased frequency of seizures may occur in patients at supratherapeutic plasma concentrations. Benzodiazepine respiratory depressant effects are more serious in patients with respiratory disease. Benzodiazepines increase the effects of other central nervous system depressants, including alcohol.

Treatment: Monitor the patient’s vital signs and institute supportive measures as indicated by the patient’s clinical state. In particular, patients may require symptomatic treatment for cardiorespiratory effects or central nervous system effects. Further absorption should be prevented using an appropriate method e.g. treatment within 1-2 hours with activated charcoal. If activated charcoal is used airway protection is imperative for drowsy patients. In case of mixed ingestion gastric lavage may be considered, however not as a routine measure. If CNS depression is severe consider the use of flumazenil, a benzodiazepine antagonist. This should only be administered under closely monitored conditions. It has a short half-life (about an hour), therefore patients administered flumazenil will require monitoring after its effects have worn off. Flumazenil is to be used with extreme caution in the presence of drugs that reduce seizure threshold (e.g. tricyclic antidepressants). Refer to the prescribing information for flumazenil, for further information on the correct use of this drug.

Slow intravenous injection: The contents of the vial must be diluted with 1 ml of water for injection prior to administration so as to avoid local irritation of the veins. The injection solution should be prepared immediately before use. IV injection should be administered slowly with continuous monitoring of EEG, respiration and blood pressure.

Intravenous infusion: Clonazepam (the vial) can be diluted for infusion in a ratio of 1 vial (1 mg) to at least 85 ml diluting media. The diluting media can be any of the following: sodium chloride 0.9%; sodium chloride 0.45% + glucose 2.5%; glucose 5% or glucose 10%. These mixtures are stable for 24 hours at room temperature. Infusion bags other than PVC should be used for infusing Clonazepam. If PVC infusion bags are used then the mixture should be infused immediately or within 4 hours. The infusion time should not exceed 8 hours. Do not prepare Clonazepam infusions using sodium bicarbonate solution, as precipitation of the solution may occur.

Intramuscular injection: The IM route should be used only in exceptional cases or if IV administration is not feasible.

Keep in a dry place away from light and heat. Keep out of the reach of children.

Specific combined vitamin preparations

Vitamin A plays an essential role in the function of retina and is essential for growh and differentiation of epithelial tissue.

Vitamin B: Plays a role in the synthesis and maintenance of coenzyme A. Necessary for lipid metabolism, carbohydrate metabolism, tissue respiration, glycogenolysis, inhibition of very low-density lipoprotein (VLDL) synthesis. May increaase chylomicron triglyceride removal from plasma.

Vitamin B12 (cyanocobalamin): Required for the maintenance of normal erthropoiesis, nucleprotein and myelin synthesis, cell reproduction and normal growth; intrinsic factor, a glycoprotein secreted by the gastric mucosa, is required for active absorption of Vitamin B12 from the Gl tract. Necessary for normal tissue respiration; plays a role in activation of pyridoxine and conversion of tryptophan to niacin.

Vitamin E is an antioxidant which preserves essential cellular constituents.

Vitamin C: Necessary for collagen formation and tissue repair; plays a role in oxidation/reduction reactions as well as other metabolic pathways including synthesis of catecholamines, carnitine, and steroids; also plays a role in conversion of folic acid to folinic acid.

Vitamin D3 is a fat-soluble sterol. It is necessary for the regulation and regulation of calcium and phosphate homoeostasis and bone mineralisation. Vitamin D is also essential for healthy bones as it aids in Calcium absorption from the Gl tract. In addition to this it stimulates bone formation. Clinical studies also show that Calcium and Vitamin D has synergistic effects on bone growth as well as in Osteoporosis and fracture prevention.

Below 1 year: 9-10 drops (0.3 ml)
1 year and above: 23-25 drops (1.0 ml) once daily or as advised by the physicians.

Multivitamin preparation with ordinary doses of component are usually nontoxic

Supplemental vitamins should not be prescribed for patients with haemochromatosis or Wilson’s disease. Hypersensitivity to any of the ingredients is contraindicated. Excessive doses of vitamin A and D can lead to hypervitaminosis. When multivitamin preparations are prescribed allowance must be made for vitamins from other sources.

Keep below 30°C temperature, away from light & moisture. Keep out of the reach of children.

Specific combined vitamin preparations

Vitamin B-Complex and Vitamin C function as cofactors of various enzymes which regulate carbohydrate, protein and fat metabolism. Thiamine (B.,) acts as a cofactor in the decarboxylation of keto acids such as pyruvic acid.

Riboflavin (B2) plays a vital role in cellular respiratory reactions in conjunction with nicotinamide.

Pyridoxine (B6) takes part in decarboxylation and interconversion of amino acids. It is also required for normal antibody-mediated and cell-mediated immune responses.

Vitamin B12 (cyanocobalamin) is required for synthesis of DNA (deoxyribo-nucleic acid) and maturation of RBCs (red blood cells). Nicotinamide (niacinamide) plays a vital role in cellular respiration in conjunction with riboflavin.

Calcium Pantothenate functions as a cofactor for enzymes involved in transfer of acetyl groups. It is also required for normal antibody response in conjunction with pyridoxine.

Folic acid, after conversion in the body to folinic acid, takes part in reactions involved in the synthesis of nucleotides and maturation of RBCs in conjunction with vitamin B12. It also plays an important role in lymphocyte-mediated immune response.

Ascorbic acid (Vitamin C) takes part in biochemical reactions involving oxidation, as in collagen synthesis, and in conversion of folic acid to folinic acid. It is also necessary for normal phagocytic function ofWBCs (white blood cells).

Thus an adequate supply of these water-soluble vitamins is required for the optimum function of various cells and tissues.Except for Vitamin B12, these water-soluble vitamins are not stored in the body to any significant extent, the excess quantities being excreted in the urine. Therefore, a regular and adequate intake of them is necessary to meet the metabolic requirements. Deficiencies of water-soluble vitamins often co-exist because of their overlapping dietary sources and metabolic interdependence. Initially the deficiency of these vitamins may be subclinical and demonstrable only by means of biochemical tests. If not corrected at this stage, it may become manifest as various symptoms, including impaired wound healing and increased susceptibility to infection. Classical deficiency diseases such as beri beri, pellagra and scurvy are rare, whereas mild and subclinical deficiencies are probably more common, even among apparently healthy individuals.

One capsule daily or as advised by the physician.

Hypersensitivity reactions have been reported with thiamine and folic acid, although these are rare.

Hypersensitivity to any of the ingredients of this preparation

The use of this capsule in patients with deficiency or increased requirement of Vitamin B-complex and Vitamin C should be accompanied by specific therapy for the primary illness.

Treatment with this capsule should be continued only until the deficiency is corrected or the need for supplementation exists. Pyridoxine in this capsule may reduce the therapeutic effects of levodopa in Parkinson’s disease.

Riboflavin in this capsule may color the urine yellow. During treatment with this capsule the urine may give a false positive result for sugar by Benedict's test because of the presence of ascorbic acid. Therefore, a test not affected by ascorbic acid should be used.

No data found

Store in a cool and dry place, away from light and children.

Rosuvastatin is indicated in-

• Heterozygous Hypercholesterolemia (Familial and Non familial)
• Homozygous Hypercholesterolemia (Familial)
• Mixed Dyslipidemia (Fredrickson Type IIa and IIb)
• Primary prevention of cardiovascular disease

Other Anti-anginal & Anti-ischaemic drugs, Statins

Rosuvastatin is a selective and competitive inhibitor of HMG-CoA reductase, the rate-limiting enzyme that converts 3-hydroxy-3-methyl glutaryl coenzyme A to mevalonate, a precursor of cholesterol. Rosuvastatin produces its lipid-modifying effects in two ways. First, it increases the number of hepatic LDL receptors on the cell surface to enhance uptake and catabolism of LDL. Second, Rosuvastatin inhibits hepatic synthesis of VLDL, which reduces the total number of VLDL and LDL particles.

Dose range: 5-40 mg once daily. Use 40 mg dose only for patients not reaching LDL-C goal with 20 mg

HoFH: Starting dose 20 mg/day.

Pediatric patients with HeFH: 5-10 mg/day for patients 8 to less than 10 years age, and 5-20 mg/day for patients 10 to 17 years of age.

Pediatric patients with HoFH: 20 mg/day for patients 7 to 17 years of age.

Rosuvastatin can be taken with or without food, at any time of day.

Rosuvastatin is generally well tolerated. The most frequent adverse events thought to be related to Rosuvastatin were headache, myalgia, constipation, asthenia, abdominal pain and nausea.

Rosuvastatin is contraindicated if-

• Known hypersensitivity to product components
• Liver disease, which may include unexplained persistent elevations in hepatic transaminase levels
• Pregnant women and women who may become pregnant
• Nursing mothers

Skeletal muscle effects (e.g., myopathy and rhabdomyolysis): Risks increase with use of 40 mg dose, advanced age (>65 year), hypothyroidism, renal impairment and combination use with cyclosporine, lopinavir/ritonavir, atazanavir/ritonavir or certain other lipid-lowering drugs. Patients should be advised to promptly report unexplained muscle pain, tenderness or weakness. Rosuvastatin can be discontinued if signs or symptoms appear.

Liver enzyme abnormalities and monitoring: Persistent elevations in hepatic transaminases can occur.

Liver enzymes should be monitored before and during treatment

Remarkable drug interactions of Rosuvastatin are-

• Cyclosporine: Combination increases Rosuvastatin exposure. Rosuvastatin dose should be limited to 5 mg once daily.
• Gemfibrosil: Combination should be avoided. If used together, Rosuvastatin dose should be limited to 10 mg once daily.
• Lopinavir/Ritonavir or atazanavir/ritonavir: Combination increases Rosuvastatin exposure. Rosuvastatin dose should be to 10 mg once daily.
• Coumarin anticoagulants: Combination prolongs international normalized ratio (INR). Stable INR should be achieved prior to starting Rosuvastatin. INR should be monitored frequently until stable upon initiation or alteration of Rosuvastatin therapy.
• Concomitant lipid-lowering therapies: Use with fibrates and niacin products may increase the risk of skeletal muscle effects.

The safety in pregnant women has not been established. It is not known whether Rosuvastatin is excreted in human milk or not.

Use in children: The safety and effectiveness in pediatric patients have not been established.

Topical Antibiotic preparations

Retapamulin selectively inhibits bacterial protein synthesis by interacting at a site on the 50S subunit of the bacterial ribosome through an interaction that is different from that of other antibiotics. This binding site involves ribosomal protein L3 and is in the region of the ribosomal P-site and peptidyl transferase center. By virtue of binding to this site, pleuromutilins inhibit peptidyl transfer, block P-site interactions, and prevent the normal formation of active 50S ribosomal subunits. Retapamulin is bacteriostatic against Staphylococcus aureus and Streptococcus pyogenes at the Retapamulin in vitro minimum inhibitory concentration (MIC) for these organisms.

A thin layer of Topibac should be applied to the affected area (up to 100 cm² in total area in adults or 2% total body surface area in pediatric patients aged 9 months or older) twice daily for 5 days. The treated area may be covered with a sterile bandage or gauze dressing if desired.

Adverse effects: Application site irritation (<2% of patients may experience).

Contraindicated in patients with hypersensitivity of any ingredient of this preparation.

Local Irritation: In the event of sensitization or severe local irritation from Retapamulin, usage should be discontinued. Not for Systemic or Mucosal Use: Retapamulin is not intended for ingestion or for oral, intranasal, ophthalmic, or intravaginal use.

The effect of concurrent application of Retapamulin and other topical products to the same area of skin has not been studied.

Pregnancy Category B. It is not known whether Retapamulin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Retapamulin is administered to a nursing woman.

Isotretinoin is indicated in severe forms of acne (such as nodular or conglobate acne or acne at risk of permanent scarring) resistant to adequate courses of standard therapy with systemic antibacterials and topical therapy.

Oral retinoids for Acne

Isotretinoin produces its effects through altering progress through the cell cycle, cell differentiation, survival, and apoptosis. These actions reduce sebum production, preventing the blockage of pores, and growth of acne causing bacteria. Isotretinoin and 4-oxo-isotretinoin both significantly reduce the production of sebum. Isotretinoin has little to no affinity for retinol binding proteins (RBPs) and retinoic acid nuclear receptors (RARs). Tretinoin and 4-oxo-tretinion bind to the RAR-γ receptor, which is suspected to be part of the action of acne treatment by isotretinoin. Isotretinoin induces apoptosis in sebocytes, leading to a decrease in sebum production. Isotretinoin also reduces the formation of comedones by reducing hyperkeratinization through an unknown mechanism. Isotretinoin does not directly kill bacteria but it does reduce the size of sebum ducts and makes the microenvironment less hospitable to acne causing bacteria. It may also increase immune mechanisms and alter chemotaxis of monocytes to reduce inflammation.

The capsules should be taken with food once or twice daily. Isotretinoin should only be prescribed by or under the supervision of physicians with expertise in the use of systemic retinoids for the treatment of severe acne and a full understanding of the risks of Isotretinoin therapy and monitoring requirements.

Adults including adolescents and the elderly: Isotretinoin therapy should be started at a dose of 0.5 mg/kg daily. The therapeutic response to Isotretinoin and some of the adverse effects are dose-related and vary between patients. This necessitates individual dosage adjustment during therapy. For most patients, the dose ranges from 0.5-1.0 mg/kg per day. Long-term remission and relapse rates are more closely related to the total dose administered than to either duration of treatment or daily dose. It has been shown that no substantial additional benefit is to be expected beyond a cumulative treatment dose of 120-150 mg/kg. The duration of treatment will depend on the individual daily dose. A treatment course of 16-24 weeks is normally sufficient to achieve remission. In the majority of patients, complete clearing of the acne is obtained with a single treatment course. In the event of a definite relapse a further course of Isotretinoin therapy may be considered using the same daily dose and cumulative treatment dose. As further improvement of the acne can be observed up to 8 weeks after discontinuation of treatment, a further course of treatment should not be considered until at least this period has elapsed.

Patients with severe renal insufficiency: In patients with severe renal insufficiency treatment should be started at a lower dose (e.g. 10 mg/day). The dose should then be increased up to 1 mg/kg/day or until the patient is receiving the maximum tolerated dose.

Children: Isotretinoin is not indicated for the treatment of prepubertal acne and is not recommended in patients less than 12 years of age due to a lack of data on efficacy and safety.

Patients with intolerance: In patients who show severe intolerance to the recommended dose, treatment may be continued at a lower dose with the consequences of a longer therapy duration and a higher risk of relapse. In order to achieve the maximum possible efficacy in these patients the dose should normally be continued at the highest tolerated dose.

Some of the side effects associated with the use of Isotretinoin are dose-related. The side effects are generally reversible after altering the dose or discontinuation of treatment, however some may persist after treatment has stopped. The following symptoms are the most commonly reported undesirable effects with Isotretinoin: dryness of the skin, dryness of the mucosae e.g. of the lips (cheilitis), the nasal mucosa (epistaxis) and the eyes (conjunctivitis).

The incidence of the adverse events was calculated from pooled clinical trial data involving 824 patients and from post-marketing data. Frequency categories are defined as Very common (³1/10), Common (³1/100 to <1/10), Uncommon (³1/1,000 to <1/100), Rare (³1/10,000 to <1/1,000), Very rare (³1/10,000 to <1/1,000) and not known (cannot be estimated from the available data.

Renal and urinary disorders: Very Rare: Glomerulonephritis. General disorders and administration site conditions: Very Rare: Granulation tissue (increased formation of), malaise. Overdose Isotretinoin is a derivative of vitamin A. Although the acute toxicity of Isotretinoin is low, signs of hypervitaminosis A could appear in cases of accidental overdose. Manifestations of acute vitamin A toxicity include severe headache, nausea or vomiting, drowsiness, irritability and pruritus. Signs and symptoms of accidental or deliberate overdosage with Isotretinoin would probably be similar. These symptoms would be expected to be reversible and to subside without the need for treatment. Pharmaceutical precautions Store in a cool and dry place protected from light.

Isotretinoin is contraindicated in women who are pregnant or breastfeeding. Isotretinoin is contraindicated in women of childbearing potential unless all of the conditions of the Pregnancy Prevention Programme are met. Isotretinoin is also contraindicated in patients with hypersensitivity to Isotretinoin or to any of the excipients. Isotretinoin is also contraindicated in patients with hepatic insufficiency, with excessively elevated blood lipid values, with hypervitaminosis A, receiving concomitant treatment with tetracyclines.

This medicinal product is contraindicated in women of childbearing potential unless all of the following conditions of the Pregnancy Prevention Programme are met: She has severe acne (such as nodular or conglobate acne or acne at risk of permanent scarring) resistant to adequate courses of standard therapy with systemic anti-bacterials and topical therapy. She understands the teratogenic risk. She understands the need for rigorous follow-up, on a monthly basis. She understands and accepts the need for effective contraception, without interruption, 1 month before starting treatment, throughout the duration of treatment and 1 month after the end of treatment. At least one and preferably two complementary forms of contraception including a barrier method should be used. Even if she has amenorrhea she must follow all of the advice on effective contraception. She should be capable of complying with effective contraceptive measures. She is informed and understands the potential consequences of pregnancy and the need to rapidly consult if there is a risk of pregnancy. She understands the need and accepts to undergo pregnancy testing before, during and 5 weeks after the end of treatment. She has acknowledged that she has understood the hazards and necessary precautions associated with the use of Isotretinoin. These conditions also concern women who are not currently sexually active unless the prescriber considers that there are compelling reasons to indicate that there is no risk of pregnancy. The prescriber must ensure that the patient complies with the conditions for pregnancy prevention as listed above, including confirmation that she has an adequate level of understanding. The patient has acknowledged the aforementioned conditions. The patient has used at least one and preferably two methods of effective contraception including a barrier method for at least 1 month prior to starting treatment and is continuing to use effective contraception throughout the treatment period and for at least 1 month after cessation of treatment. Negative pregnancy test results have been obtained before, during and 5 weeks after the end of treatment. The dates and results of pregnancy tests should be documented.

Contraception: Female patients must be provided with comprehensive information on pregnancy prevention and should be referred for contraceptive advice if they are not using effective contraception. As a minimum requirement, female patients at potential risk of pregnancy must use at least one effective method of contraception. Preferably the patient should use two complementary forms of contraception including a barrier method. Contraception should be continued for at least 1 month after stopping treatment with Isotretinoin, even in patients with amenorrhea.

Pregnancy testing: According to local practice, medically supervised pregnancy tests with a minimum sensitivity of 25mIU/mL are recommended to be performed in the first 3 days of the menstrual cycle, as follows.

Prior to starting therapy: In order to exclude the possibility of pregnancy prior to starting contraception, it is recommended that an initial medically supervised pregnancy test should be performed and its date and result recorded. In patients without regular menses, the timing of this pregnancy test should reflect the sexual activity of the patient and should be undertaken approximately 3 weeks after the patient last had unprotected sexual intercourse. The prescriber should educate the patient about contraception. A medically supervised pregnancy test should also be performed during the consultation when Isotretinoin is prescribed or in the 3 days prior to the visit to the prescriber, and should have been delayed until the patient had been using effective contraception for at least 1 month. This test should ensure the patient is not pregnant when she starts treatment with Isotretinoin.

Follow-up visits: Follow-up visits should be arranged at 28 day intervals. The need for repeated medically supervised pregnancy tests every month should be determined according to local practice including consideration of the patient’s sexual activity and recent menstrual history (abnormal menses, missed periods or amenorrhea). Where indicated, follow-up pregnancy tests should be performed on the day of the prescribing visit or in the 3 days prior to the visit to the prescriber.

End of treatment: Five weeks after stopping treatment, women should undergo a final pregnancy test to exclude pregnancy.

Prescribing and dispensing restrictions: Prescriptions of Isotretinoin for women of childbearing potential should be limited to 30 days of treatment and continuation of treatment requires a new prescription. Ideally, pregnancy testing, issuing a prescription and dispensing of Isotretinoin should occur on the same day. Dispensing of Isotretinoin should occur within a maximum of 7 days of the prescription.

Male patients: The available data suggest that the level of maternal exposure from the semen of the patients receiving Isotretinoin, is not of a sufficient magnitude to be associated with the teratogenic effects of Isotretinoin. Male patients should be reminded that they must not share their medication with anyone, particularly not females.

Additional precautions: Patients should be instructed never to give this medicinal product to another person, and to return any unused capsules to their pharmacist at the end of treatment. Patients should not donate blood during therapy and for 1 month following discontinuation of Isotretinoin because of the potential risk to the foetus of a pregnant transfusion recipient.

Psychiatric disorders: Depression, depression aggravated, anxiety, aggressive tendencies, mood alterations, psychotic symptoms, and very rarely, suicidal ideation, suicide attempts and suicide have been reported in patients treated with Isotretinoin. Particular care needs to be taken in patients with a history of depression and all patients should be monitored for signs of depression and referred for appropriate treatment if necessary. However, discontinuation of Isotretinoin may be insufficient to alleviate symptoms and therefore further psychiatric or psychological evaluation may be necessary.

Skin and subcutaneous tissues disorders: Acute exacerbation of acne is occasionally seen during the initial period but this subsides with continued treatment, usually within 7-10 days, and usually does not require dose adjustment. Exposure to intense sunlight or to UV rays should be avoided. Where necessary a sun-protection product with a high protection factor of at least SPF 15 should be used. Aggressive chemical dermabrasion and cutaneous laser treatment should be avoided in patients on Isotretinoin for a period of 5-6 months after the end of the treatment because of the risk of hypertrophic scarring in atypical areas and more rarely post inflammatory hyper or hypopigmentation in treated areas. Wax depilation should be avoided in patients on Isotretinoin for at least a period of 6 months after treatment because of the risk of epidermal stripping. Concurrent administration of Isotretinoin with topical keratolytic or exfoliative anti-acne agents should be avoided as local irritation may increase. Patients should be advised to use a skin moisturising ointment or cream and a lip balm from the start of treatment as Isotretinoin is likely to cause dryness of the skin and lips. There have been post-marketing reports of severe skin reactions (e.g. erythema multiforme (EM), Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN)) associated with Isotretinoin use. As these events may be difficult to distinguish from other skin reactions that may occur, patients should be advised of the signs and symptoms and monitored closely for severe skin reactions. If a severe skin reaction is suspected, Isotretinoin treatment should be discontinued. Allergic reactions: Anaphylactic reactions have been rarely reported, in some cases after previous topical exposure to retinoids. Allergic cutaneous reactions are reported infrequently. Serious cases of allergic vasculitis, often with purpura (bruises and red patches) of the extremities and extracutaneous involvement have been reported. Severe allergic reactions necessitate interruption of therapy and careful monitoring.

Eye disorders: Dry eyes, corneal opacities, decreased night vision and keratitis usually resolve after discontinuation of therapy. Dry eyes can be helped by the application of a lubricating eye ointment or by the application of tear replacement therapy. Intolerance to contact lenses may occur which may necessitate the patient to wear glasses during treatment. Decreased night vision has also been reported and the onset in some patients was sudden. Withdrawal of Isotretinoin may be necessary.

Musculo-skeletal and connective tissue disorders: Myalgia, arthralgia and increased serum creatine phosphokinase values have been reported in patients receiving Isotretinoin, particularly in those undertaking vigorous physical activity. Bone changes including premature epiphyseal closure, hyperostosis, and calcification of tendons and ligaments have occurred after several years of administration at very high doses for treating disorders of keratinisation. The dose levels, duration of treatment and total cumulative dose in these patients generally far exceeded those recommended for the treatment of acne.

Benign intracranial hypertension: Cases of benign intracranial hypertension have been reported, some of which involved concomitant use of tetracyclines. Signs and symptoms of benign intracranial hypertension include headache, nausea and vomiting, visual disturbances and papilloedema. Patients who develop benign intracranial hypertension should discontinue Isotretinoin immediately.

Hepatobiliary disorders: Liver enzymes should be checked before treatment, 1 month after the start of treatment, and subsequently at 3 monthly intervals unless more frequent monitoring is clinically indicated. Transient and reversible increases in liver transaminases have been reported. In many cases these changes have been within the normal range and values have returned to baseline levels during treatment. However, in the event of persistent clinically relevant elevation of transaminase levels, reduction of the dose or discontinuation of treatment should be considered.

Renal insufficiency: Renal insufficiency and renal failure do not affect the pharmacokinetics of Isotretinoin. Therefore, Isotretinoin can be given to patients with renal insufficiency. However, it is recommended that patients are started on a low dose and titrated up to the maximum tolerated dose.

Lipid Metabolism: Serum lipids (fasting values) should be checked before treatment, 1 month after the start of treatment, and subsequently at 3 monthly intervals unless more frequent monitoring is clinically indicated. Elevated serum lipid values usually return to normal on reduction of the dose or discontinuation of treatment and may also respond to dietary measures. Isotretinoin has been associated with an increase in plasma triglyceride levels. Isotretinoin should be discontinued if hypertriglyceridaemia cannot be controlled at an acceptable level or if symptoms of pancreatitis occur. Levels in excess of 800mg/dL or 9mmol/L are sometimes associated with acute pancreatitis, which may be fatal.

Gastrointestinal disorders: Isotretinoin has been associated with inflammatory bowel disease (including regional ileitis) in patients without a prior history of intestinal disorders. Patients experiencing severe (hemorrhagic) diarrhoea should discontinue Isotretinoin immediately.

High Risk Patients: In patients with diabetes, obesity, alcoholism or a lipid metabolism disorder undergoing treatment with Isotretinoin, more frequent checks of serum values for lipids and/or blood glucose may be necessary. Elevated fasting blood sugars have been reported, and new cases of diabetes have been diagnosed during Isotretinoin therapy.

Additive adverse effects with vit A or its derivatives. Decreased efficacy of microdosed progesterone (use 2 forms of contraception).Increased risk of local irritation with topical keratolytic or exfoliative anti-acne agents. Oxidising agents (e.g. benzoyl peroxide) may reduce the efficacy of topical isotretinoin.

Pregnancy is an absolute contraindication to treatment with Isotretinoin. If pregnancy does occur in spite of these precautions during treatment with Isotretinoin or in the month following, there is a great risk of very severe and serious malformation of the foetus. The foetal malformations associated with exposure to Isotretinoin include central nervous system abnormalities (hydrocephalus, cerebellar malformation/abnormalities, microcephaly), facial dysmorphia, cleft palate, external ear abnormalities (absence of external ear, small or absent external auditory canals), eye abnormalities (microphthalmia), cardiovascular abnormalities (conotruncal malformations such as tetralogy of Fallot, transposition of great vessels, septal defects), thymus gland abnormality and parathyroid gland abnormalities. There is also an increased incidence of spontaneous abortion. If pregnancy occurs in a woman treated with Isotretinoin, treatment must be stopped and the patient should be referred to a physician specialised or experienced in teratology for evaluation and advice. Isotretinoin is highly lipophilic, therefore the passage of Isotretinoin into human milk is very likely. Due to the potential for adverse effects in the child exposed via mothers’ milk, the use of Isotretinoin is contraindicated in nursing mothers.

Keep below 30°C temperature, away from light & moisture. Keep out of the reach of children.

Isotretinoin is indicated in severe forms of acne (such as nodular or conglobate acne or acne at risk of permanent scarring) resistant to adequate courses of standard therapy with systemic antibacterials and topical therapy.

Isotretinoin also reduces the formation of comedones by reducing hyperkeratinization through an unknown mechanism. Isotretinoin does not directly kill bacteria but it does reduce the size of sebum ducts and makes the microenvironment less hospitable to acne causing bacteria. It may also increase immune mechanisms and alter chemotaxis of monocytes to reduce inflammation.

The capsules should be taken with food once or twice daily. Isotretinoin should only be prescribed by or under the supervision of physicians with expertise in the use of systemic retinoids for the treatment of severe acne and a full understanding of the risks of Isotretinoin therapy and monitoring requirements.

Adults including adolescents and the elderly: Isotretinoin therapy should be started at a dose of 0.5 mg/kg daily. The therapeutic response to Isotretinoin and some of the adverse effects are dose-related and vary between patients. This necessitates individual dosage adjustment during therapy. For most patients, the dose ranges from 0.5-1.0 mg/kg per day. Long-term remission and relapse rates are more closely related to the total dose administered than to either duration of treatment or daily dose. It has been shown that no substantial additional benefit is to be expected beyond a cumulative treatment dose of 120-150 mg/kg. The duration of treatment will depend on the individual daily dose. A treatment course of 16-24 weeks is normally sufficient to achieve remission. In the majority of patients, complete clearing of the acne is obtained with a single treatment course. In the event of a definite relapse a further course of Isotretinoin therapy may be considered using the same daily dose and cumulative treatment dose. As further improvement of the acne can be observed up to 8 weeks after discontinuation of treatment, a further course of treatment should not be considered until at least this period has elapsed.

Patients with severe renal insufficiency: In patients with severe renal insufficiency treatment should be started at a lower dose (e.g. 10 mg/day). The dose should then be increased up to 1 mg/kg/day or until the patient is receiving the maximum tolerated dose.

Children: Isotretinoin is not indicated for the treatment of prepubertal acne and is not recommended in patients less than 12 years of age due to a lack of data on efficacy and safety.

Patients with intolerance: In patients who show severe intolerance to the recommended dose, treatment may be continued at a lower dose with the consequences of a longer therapy duration and a higher risk of relapse. In order to achieve the maximum possible efficacy in these patients the dose should normally be continued at the highest tolerated dose.

Some of the side effects associated with the use of Isotretinoin are dose-related. The side effects are generally reversible after altering the dose or discontinuation of treatment, however some may persist after treatment has stopped. The following symptoms are the most commonly reported undesirable effects with Isotretinoin: dryness of the skin, dryness of the mucosae e.g. of the lips (cheilitis), the nasal mucosa (epistaxis) and the eyes (conjunctivitis).

The incidence of the adverse events was calculated from pooled clinical trial data involving 824 patients and from post-marketing data. Frequency categories are defined as Very common (³1/10), Common (³1/100 to <1/10), Uncommon (³1/1,000 to <1/100), Rare (³1/10,000 to <1/1,000), Very rare (³1/10,000 to <1/1,000) and not known (cannot be estimated from the available data.

Renal and urinary disorders: Very Rare: Glomerulonephritis. General disorders and administration site conditions: Very Rare: Granulation tissue (increased formation of), malaise. Overdose Isotretinoin is a derivative of vitamin A. Although the acute toxicity of Isotretinoin is low, signs of hypervitaminosis A could appear in cases of accidental overdose. Manifestations of acute vitamin A toxicity include severe headache, nausea or vomiting, drowsiness, irritability and pruritus. Signs and symptoms of accidental or deliberate overdosage with Isotretinoin would probably be similar. These symptoms would be expected to be reversible and to subside without the need for treatment. Pharmaceutical precautions Store in a cool and dry place protected from light.

Isotretinoin is contraindicated in women who are pregnant or breastfeeding. Isotretinoin is contraindicated in women of childbearing potential unless all of the conditions of the Pregnancy Prevention Programme are met. Isotretinoin is also contraindicated in patients with hypersensitivity to Isotretinoin or to any of the excipients. Isotretinoin is also contraindicated in patients with hepatic insufficiency, with excessively elevated blood lipid values, with hypervitaminosis A, receiving concomitant treatment with tetracyclines.

This medicinal product is contraindicated in women of childbearing potential unless all of the following conditions of the Pregnancy Prevention Programme are met: She has severe acne (such as nodular or conglobate acne or acne at risk of permanent scarring) resistant to adequate courses of standard therapy with systemic anti-bacterials and topical therapy. She understands the teratogenic risk. She understands the need for rigorous follow-up, on a monthly basis. She understands and accepts the need for effective contraception, without interruption, 1 month before starting treatment, throughout the duration of treatment and 1 month after the end of treatment. At least one and preferably two complementary forms of contraception including a barrier method should be used. Even if she has amenorrhea she must follow all of the advice on effective contraception. She should be capable of complying with effective contraceptive measures. She is informed and understands the potential consequences of pregnancy and the need to rapidly consult if there is a risk of pregnancy. She understands the need and accepts to undergo pregnancy testing before, during and 5 weeks after the end of treatment. She has acknowledged that she has understood the hazards and necessary precautions associated with the use of Isotretinoin. These conditions also concern women who are not currently sexually active unless the prescriber considers that there are compelling reasons to indicate that there is no risk of pregnancy. The prescriber must ensure that the patient complies with the conditions for pregnancy prevention as listed above, including confirmation that she has an adequate level of understanding. The patient has acknowledged the aforementioned conditions. The patient has used at least one and preferably two methods of effective contraception including a barrier method for at least 1 month prior to starting treatment and is continuing to use effective contraception throughout the treatment period and for at least 1 month after cessation of treatment. Negative pregnancy test results have been obtained before, during and 5 weeks after the end of treatment. The dates and results of pregnancy tests should be documented.

Contraception: Female patients must be provided with comprehensive information on pregnancy prevention and should be referred for contraceptive advice if they are not using effective contraception. As a minimum requirement, female patients at potential risk of pregnancy must use at least one effective method of contraception. Preferably the patient should use two complementary forms of contraception including a barrier method. Contraception should be continued for at least 1 month after stopping treatment with Isotretinoin, even in patients with amenorrhea.

Pregnancy testing: According to local practice, medically supervised pregnancy tests with a minimum sensitivity of 25mIU/mL are recommended to be performed in the first 3 days of the menstrual cycle, as follows.

Prior to starting therapy: In order to exclude the possibility of pregnancy prior to starting contraception, it is recommended that an initial medically supervised pregnancy test should be performed and its date and result recorded. In patients without regular menses, the timing of this pregnancy test should reflect the sexual activity of the patient and should be undertaken approximately 3 weeks after the patient last had unprotected sexual intercourse. The prescriber should educate the patient about contraception. A medically supervised pregnancy test should also be performed during the consultation when Isotretinoin is prescribed or in the 3 days prior to the visit to the prescriber, and should have been delayed until the patient had been using effective contraception for at least 1 month. This test should ensure the patient is not pregnant when she starts treatment with Isotretinoin.

Follow-up visits: Follow-up visits should be arranged at 28 day intervals. The need for repeated medically supervised pregnancy tests every month should be determined according to local practice including consideration of the patient’s sexual activity and recent menstrual history (abnormal menses, missed periods or amenorrhea). Where indicated, follow-up pregnancy tests should be performed on the day of the prescribing visit or in the 3 days prior to the visit to the prescriber.

End of treatment: Five weeks after stopping treatment, women should undergo a final pregnancy test to exclude pregnancy.

Prescribing and dispensing restrictions: Prescriptions of Isotretinoin for women of childbearing potential should be limited to 30 days of treatment and continuation of treatment requires a new prescription. Ideally, pregnancy testing, issuing a prescription and dispensing of Isotretinoin should occur on the same day. Dispensing of Isotretinoin should occur within a maximum of 7 days of the prescription.

Male patients: The available data suggest that the level of maternal exposure from the semen of the patients receiving Isotretinoin, is not of a sufficient magnitude to be associated with the teratogenic effects of Isotretinoin. Male patients should be reminded that they must not share their medication with anyone, particularly not females.

Additional precautions: Patients should be instructed never to give this medicinal product to another person, and to return any unused capsules to their pharmacist at the end of treatment. Patients should not donate blood during therapy and for 1 month following discontinuation of Isotretinoin because of the potential risk to the foetus of a pregnant transfusion recipient.

Psychiatric disorders: Depression, depression aggravated, anxiety, aggressive tendencies, mood alterations, psychotic symptoms, and very rarely, suicidal ideation, suicide attempts and suicide have been reported in patients treated with Isotretinoin. Particular care needs to be taken in patients with a history of depression and all patients should be monitored for signs of depression and referred for appropriate treatment if necessary. However, discontinuation of Isotretinoin may be insufficient to alleviate symptoms and therefore further psychiatric or psychological evaluation may be necessary.

Skin and subcutaneous tissues disorders: Acute exacerbation of acne is occasionally seen during the initial period but this subsides with continued treatment, usually within 7-10 days, and usually does not require dose adjustment. Exposure to intense sunlight or to UV rays should be avoided. Where necessary a sun-protection product with a high protection factor of at least SPF 15 should be used. Aggressive chemical dermabrasion and cutaneous laser treatment should be avoided in patients on Isotretinoin for a period of 5-6 months after the end of the treatment because of the risk of hypertrophic scarring in atypical areas and more rarely post inflammatory hyper or hypopigmentation in treated areas. Wax depilation should be avoided in patients on Isotretinoin for at least a period of 6 months after treatment because of the risk of epidermal stripping. Concurrent administration of Isotretinoin with topical keratolytic or exfoliative anti-acne agents should be avoided as local irritation may increase. Patients should be advised to use a skin moisturising ointment or cream and a lip balm from the start of treatment as Isotretinoin is likely to cause dryness of the skin and lips. There have been post-marketing reports of severe skin reactions (e.g. erythema multiforme (EM), Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN)) associated with Isotretinoin use. As these events may be difficult to distinguish from other skin reactions that may occur, patients should be advised of the signs and symptoms and monitored closely for severe skin reactions. If a severe skin reaction is suspected, Isotretinoin treatment should be discontinued. Allergic reactions: Anaphylactic reactions have been rarely reported, in some cases after previous topical exposure to retinoids. Allergic cutaneous reactions are reported infrequently. Serious cases of allergic vasculitis, often with purpura (bruises and red patches) of the extremities and extracutaneous involvement have been reported. Severe allergic reactions necessitate interruption of therapy and careful monitoring.

Eye disorders: Dry eyes, corneal opacities, decreased night vision and keratitis usually resolve after discontinuation of therapy. Dry eyes can be helped by the application of a lubricating eye ointment or by the application of tear replacement therapy. Intolerance to contact lenses may occur which may necessitate the patient to wear glasses during treatment. Decreased night vision has also been reported and the onset in some patients was sudden. Withdrawal of Isotretinoin may be necessary.

Musculo-skeletal and connective tissue disorders: Myalgia, arthralgia and increased serum creatine phosphokinase values have been reported in patients receiving Isotretinoin, particularly in those undertaking vigorous physical activity. Bone changes including premature epiphyseal closure, hyperostosis, and calcification of tendons and ligaments have occurred after several years of administration at very high doses for treating disorders of keratinisation. The dose levels, duration of treatment and total cumulative dose in these patients generally far exceeded those recommended for the treatment of acne.

Benign intracranial hypertension: Cases of benign intracranial hypertension have been reported, some of which involved concomitant use of tetracyclines. Signs and symptoms of benign intracranial hypertension include headache, nausea and vomiting, visual disturbances and papilloedema. Patients who develop benign intracranial hypertension should discontinue Isotretinoin immediately.

Hepatobiliary disorders: Liver enzymes should be checked before treatment, 1 month after the start of treatment, and subsequently at 3 monthly intervals unless more frequent monitoring is clinically indicated. Transient and reversible increases in liver transaminases have been reported. In many cases these changes have been within the normal range and values have returned to baseline levels during treatment. However, in the event of persistent clinically relevant elevation of transaminase levels, reduction of the dose or discontinuation of treatment should be considered.

Renal insufficiency: Renal insufficiency and renal failure do not affect the pharmacokinetics of Isotretinoin. Therefore, Isotretinoin can be given to patients with renal insufficiency. However, it is recommended that patients are started on a low dose and titrated up to the maximum tolerated dose.

Lipid Metabolism: Serum lipids (fasting values) should be checked before treatment, 1 month after the start of treatment, and subsequently at 3 monthly intervals unless more frequent monitoring is clinically indicated. Elevated serum lipid values usually return to normal on reduction of the dose or discontinuation of treatment and may also respond to dietary measures. Isotretinoin has been associated with an increase in plasma triglyceride levels. Isotretinoin should be discontinued if hypertriglyceridaemia cannot be controlled at an acceptable level or if symptoms of pancreatitis occur. Levels in excess of 800mg/dL or 9mmol/L are sometimes associated with acute pancreatitis, which may be fatal.

Gastrointestinal disorders: Isotretinoin has been associated with inflammatory bowel disease (including regional ileitis) in patients without a prior history of intestinal disorders. Patients experiencing severe (hemorrhagic) diarrhoea should discontinue Isotretinoin immediately.

High Risk Patients: In patients with diabetes, obesity, alcoholism or a lipid metabolism disorder undergoing treatment with Isotretinoin, more frequent checks of serum values for lipids and/or blood glucose may be necessary. Elevated fasting blood sugars have been reported, and new cases of diabetes have been diagnosed during Isotretinoin therapy.

Additive adverse effects with vit A or its derivatives. Decreased efficacy of microdosed progesterone (use 2 forms of contraception).Increased risk of local irritation with topical keratolytic or exfoliative anti-acne agents. Oxidising agents (e.g. benzoyl peroxide) may reduce the efficacy of topical isotretinoin.

Pregnancy is an absolute contraindication to treatment with Isotretinoin. If pregnancy does occur in spite of these precautions during treatment with Isotretinoin or in the month following, there is a great risk of very severe and serious malformation of the foetus. The foetal malformations associated with exposure to Isotretinoin include central nervous system abnormalities (hydrocephalus, cerebellar malformation/abnormalities, microcephaly), facial dysmorphia, cleft palate, external ear abnormalities (absence of external ear, small or absent external auditory canals), eye abnormalities (microphthalmia), cardiovascular abnormalities (conotruncal malformations such as tetralogy of Fallot, transposition of great vessels, septal defects), thymus gland abnormality and parathyroid gland abnormalities. There is also an increased incidence of spontaneous abortion. If pregnancy occurs in a woman treated with Isotretinoin, treatment must be stopped and the patient should be referred to a physician specialised or experienced in teratology for evaluation and advice. Isotretinoin is highly lipophilic, therefore the passage of Isotretinoin into human milk is very likely. Due to the potential for adverse effects in the child exposed via mothers’ milk, the use of Isotretinoin is contraindicated in nursing mothers.

Keep below 30°C temperature, away from light & moisture. Keep out of the reach of children.

Isotretinoin topical gel is indicated for the treatment of mild to moderate inflammatory and non-inflammatory acne vulgaris.

Topical retinoid and related preparations

Isotretinoin produces its effects through altering progress through the cell cycle, cell differentiation, survival, and apoptosis. These actions reduce sebum production, preventing the blockage of pores, and growth of acne causing bacteria. Isotretinoin and 4-oxo-isotretinoin both significantly reduce the production of sebum. Isotretinoin has little to no affinity for retinol binding proteins (RBPs) and retinoic acid nuclear receptors (RARs). Tretinoin and 4-oxo-tretinion bind to the RAR-γ receptor, which is suspected to be part of the action of acne treatment by isotretinoin. Isotretinoin induces apoptosis in sebocytes, leading to a decrease in sebum production. Isotretinoin also reduces the formation of comedones by reducing hyperkeratinization through an unknown mechanism. Isotretinoin does not directly kill bacteria but it does reduce the size of sebum ducts and makes the microenvironment less hospitable to acne causing bacteria. It may also increase immune mechanisms and alter chemotaxis of monocytes to reduce inflammation.

Apply Isotretinoin 0.05% gel cautiously over the affected area once or twice daily. Patients should be advised that 6-8 weeks of treatment may be required before a therapeutic effect is observed. The safety and efficacy of Isotretinoin have not been established in children since acne vulgaris rarely present in this age group. There are no specific recommendations for use in the elderly. Acne vulgaris does not present in the elderly.

In normal use, Isotretinoin may cause stinging, burning or irritation; erythema and peeling at the site of application may occur. If undue irritation occurs, treatment should be interrupted temporarily and resumed once the reaction subsides. If irritation persists, treatment should be discontinued. Reactions will normally resolve on discontinuation of therapy.

Isotretinoin 0.05% gel is contra-indicated in patients with known hypersensitivity to Isotretinoin.

Contact with the mouth, eyes and mucous membranes and with abraded or eczematous skin should be avoided. Care should be taken not to let the medication accumulate in skin fold areas and in the angles of the nose. Application to sensitive areas of skin, such as the neck, should be made with caution. Although Tretinoin has not been shown to initiate or promote carcinogenesis in humans, Tretinoin applied topically to albino hairless mice had resulted in a dose-related acceleration in ultraviolet-B radiation induced cutaneous tumours. The same author also observed the opposite effect in another study of low, non-irritating concentrations of Tretinoin. The significance of these findings as related to man is unknown; however, caution should be observed in patients with a personal or family history of cutaneous epithelioma. Exposure to sunlight of areas treated with Isotretinoin should be avoided or minimised. When exposure to strong sunlight cannot be avoided a sunscreen product and protective clothing should be used. Patients with sunburn should not use Isotretinoin due to the possibility of increased sensitivity to sunlight. The use of sunlamps should be avoided during treatment.

Concomitant topical medication should be used with caution during therapy with Isotretinoin. Particular caution should be exercised when using preparations containing a peeling agent (for example Benzoyl Peroxide) or abrasive cleansers.

Pregnancy Category B. There is inadequate evidence of the safety of topically applied Isotretinoin in human pregnancy. Isotretinoin has been associated with teratogenicity in humans when administered systemically. Reproduction studies conducted in rabbits using Isotretinoin applied topically at up to 60 times the human dose have, however, revealed no harm to the foetus. The use of Isotretinoin should be avoided during pregnancy. Percutaneous absorption of Isotretinoin from Isotretinoin 0.05% gel is negligible. It is not known, however, whether Isotretinoin is excreted in human milk. Isotretinoin should not be used during lactation.

Acute overdosage of Isotretinoin has not been reported to date. Accidental ingestion of Isotretinoin resulting in overdosage of Isotretinoin could be expected to induce symptoms of hypervitaminosis A. These include severe headaches, nausea or vomiting, drowsiness, irritability and pruritus.

Store in a cool and dry place, protected from light.

For topical application in the treatment of acne vulgaris in which comedones, papules and pustules predominate.

Topical retinoid and related preparations

Although the exact mode of action of Tretinoin is unknown, current evidence suggests that topical Tretinoin decreases cohesiveness of follicular epithelial cells with decreased microcomedo formation. Additionally Tretinoin stimulates mitotic activity and increases turnover of follicular epithelial cells, causing extrusion of the comedones, papules and pustules.

This cream should be applied sparingly to the whole affected area once or twice daily. The skin should be thoroughly cleaned and dried before application. Patient should be advised that 6 to 8 weeks of treatment may be required before a therapeutic effect is observed. Moisturizers and cosmetics may be used during treatment with Tretinoin cream but should not be applied to the skin at the same time. Astringent toiletries should be avoided.

Initial external application of Tretinoin generally may cause burning or slight irritation, erythema and peeling at the site of application may also occur. If irritation becomes severe and persists, discontinue application and consult your physicians, if necessary.

Tretinoin is contraindicated to those who are highly sensitive to any of the ingredients. This cream should not be used in patients with a personal or family history of cutaneous epithelioma (skin cancer).

Avoid contact of Tretinoin with lips, mouth, eyes, eyelids, nostrils or another mucous membrane. If contact in these areas occurs, careful washing with water is recommended. Apply the cream to sensitive areas of skin, such as the neck, with caution. Do not use it on broken, eczematous or sun burned skin.

Other topical acne treatments should be used with caution during treatment with Tretinoin. Particular caution should be exercised when using preparation containing a peeling agent for example benzoyl peroxide. It is also possible to apply Tretinoin and benzoyl peroxide alternately. The suggested regimens are either Tretinoin in the morning and benzoyl peroxide in the evening or the preparations should be used on alternate days.

There is an inadequate evidence of the safety of topically applied Tretinoin in human pregnancy. Tretinoin has been associated with teratogenicity in human when administered systemically. So the cream should not be used during pregnancy and lactation.

Keep out of the reach of children. Keep in a cool & dry place, protect from light.
