Combined anxiolytics & anti-depressant drugs

This consists of two well known and well proven compounds: flupentixol-a neuroleptic with anxiolytic and antidepressant properties of its own when given in small doses, and melitracen-a bipolar thymoleptic with activating properties in low doses. In combination the compounds render a preparation with antidepressant, anxiolytic and activating properties. Maximal serum concentration is reached in about 4 hours after oral administration of flupentixol and in about 4 hours after oral administration of melitracen. The biological half-life of flupentixol is about 35 hours and that of melitracen is about 19 hours. The combination of flupentixol and melitracen does not seem to influence the pharmacokinetic properties of the individual compounds.

Adults: Usually 2 tablets orally daily in the morning and noon. In severe cases, the morning dose may be increased to 2 tablets.

Elderly patients: 1 tablet in the morning.

Maintenance dose: Usually 1 tablet orally in the morning. In cases of insomnia or severe restlessness, additional treatment with a sedative in the acute phase is recommended.

In the recommended doses side effects are rare. These could be transient restlessness and insomnia.

If previously the patient has been treated with tranquillizers with sedative effect these should be withdrawn gradually.

This tablet may enhance the response to alcohol, barbiturates and other CNS depressants. Simultaneous administration of MAO-inhibitors may cause hypertensive crises. Neuroleptics and thymoleptics reduce the antihypertensive effect of guanethidine and similar acting compounds and thymoleptics enhance the effects of adrenaline and noradrenaline.

This tablet should preferably not be given during pregnancy and lactation.

In cases of overdosage the symptoms of intoxications by melitracen, especially of anticholinergic nature, dominate. More rarely extrapyramidal symptoms due to flupentixol occur. Symptomatic and Supportive. Gastric lavage should be carried out as soon as possible and activated charcoal may be administered. Measures aimed at supporting the respiratory and cardiovascular systems should be instituted. Epinephrine (adrenaline) must not be used for such patients. Convulsions may be treated with diazepam and extrapyramidal symptoms with biperiden.

Store at a temperature not exceeding 30°C in a dry place. Protect from light. Keep out of reach of children.

It is indicated for the relief of symptoms associated with seasonal & perennial allergic rhinitis. It is also indicated for the treatment of the uncomplicated skin manifestations of chronic idiopathic urticaria and allergen induced asthma.

Sedating Anti-histamine

Cetirizine Hydrochloride is a potent H1 receptor antagonist without any significant anticholinergic and antiserotonic effects. At pharmacologically active dose levels, it has almost no drowsiness effect and does not cause behavioral changes. It inhibits the histamine-mediated early phase of the allergic reaction and also reduces the migration of inflammatory cells and the release of mediators associated with the late phase of the allergic reaction.

Pharmacokinetics: Cetirizine 10 mg achieves peak plasma concentrations of 257 mcg/L within one hour of administration (980 mcg/L in children). Food does not affect the extent of absorption, but it may slightly reduce the rate. Peak blood levels 0.3 micrograms/ml are reached between thirty & sixty minutes after administration of 10 mg dose of Cetirizine. Its plasma half-life is approximately 11 hours. Absorption is very consistent from one subject to the next. Its renal clearance is 30 ml/minute and the excretion half-life is approximately nine hours.

Adults and Children 6 years and older: 1 tablet or 2 teaspoonfuls daily (or 1 teaspoonful twice daily).

Children 2-6 years: 1 teaspoonful once daily or 1/2 teaspoonful twice daily.

Children 6 months to 2 years : 1/2 teaspoonful once daily. The dose in children 12-23 months of age can be increased to a maximum dose as 1/2 teaspoonful every 12 hours.

The most common side effects that occurred more frequently on Cetirizine is somnolence.

It is contraindicated in patients with a history of hypersensitivity to Cetirizine or hydroxyzine.

Caution should be exercised when driving a car or operating a heavy machinery.

No clinically significant drug interactions have been found with Theophylline, Azithromycin, Pseudoephedrine, Ketoconazole or Erythromycin and with other drugs.

US FDA Pregnancy Category of Cetirizine Hydrochloride is B. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Cetirizine Hydrochloride has been shown to be excreted in human milk. So, caution should be exercised when Cetirizine Hydrochloride is administered to a nursing woman.

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

Fenofibrate is indicated for hyperlipidemias of type lla, llb, III, IV & V in patients who have not responded adequately to diet & other appropriate measures.

Fibrates

Fenofibrate is a fibric acid derivative. Fenofibrate is rapidly hydrolyzed after oral ingestion to its pharmacologically active form, fenofibric acid. Fenofibric acid produces reductions in total cholesterol, LDL cholesterol, Apo-lipoprotein B, Total triglycerides and VLDL. In addition, treatment with Fenofibrate results in increases in HDL and apo-proteins apoAI apoAII. Fenofibrate also reduces serum uric acid levels in hyperuricemic and normal individuals by increasing the urinary excretion of uric acid. The micronised form of Nofiate (Fenofibrate) has enhanced absorption over the non-micronised formulation.

Gastro-intestinal (e.g. nausea, anorexia, gastric pain), pruritus, urticaria, impotence, also headache, dizziness, vertigo, fatigue, hair loss; myotoxicity.

Fenofibrate is contraindicated in patients with hypersensitivity to Fenofibrate, severe renal or hepatic impairment, existing gall bladder disease, breast feeding mothers, photosensitivity to ketoprofen.

Special care needed in patients with renal disease, as progressive increases in serum creatinine concentration or failure to follow dosage guidelines may result in myotoxicity; discontinue if myotoxicity suspected or creatinine kinase concentration increases significantly. Liver function tests recommended every 3 months for first year.

Fenofibrate has been reported to potentiate the anticoagulant effects of warfarin. When administered with antidiabetic drug it may improve glucose tolerance and have additive effect. Fenofibrate may also increase the nephrotoxicity of cyclosporine. Due to a potential increase in the risk of rhabdomyolysis, cautions should be taken against the use of Fenofibrate with HMG-CoA reductase inhibitors. However, the use of low-dose statins with Fenofibrate appears to be well tolerated.

Fenofibrate is not recommended for pregnant women.

There is no specific treatment for overdose with Fenofibrate. General supportive care of the patients is indicated, including monitoring of vital signs and observation of clinical status, should an overdose occur. Because Fenofibrate is highly bound to plasma proteins, hemodialysis should not be considered.

Do not store above 30°C. Keep away from light and out of the reach of children.

Centrally acting Skeletal Muscle Relaxants

Tizanidine is a centrally acting skeletal muscle relaxant. Its principal site of action is the spinal cord, where the evidence suggests that, by stimulating presynaptic alpha2 receptors, it inhibits the release of excitatory amino acids that stimulate N-methyl-D aspartate (NMDA) receptors.

Polysynaptic signal transmission at spinal interneuron level, which is responsible for excessive muscle tone, is thus inhibited and muscle tone reduced. In addition to its muscle-relaxant properties, tizanidine also exerts a moderate central analgesic effect.

Pharmacodynamic: Tizanidine is effective in both acute painful muscle spasms and chronic spasticity of spinal and cerebral origin. It reduces resistance to passive movements, alleviates spasms and clonus, and may improve voluntary strength. The antispastic activity (measured by the Ashworth score and pendulum test) and adverse effects (heart rate and blood pressure) of Tizanidine are related to plasma tizanidine concentrations.

Tizanidine has a narrow therapeutic index and high inter-patient variability in tizanidine plasma concentrations which requires individualized dose adjustment. A low starting dose of 2 mg three times daily can minimize the risk for adverse effects. The dose should be carefully adjusted upward according to the needs of the individual patient.

Relief of painful muscle spasms: The usual dose is 2 to 4 mg three times daily in tablet form. In severe cases, an extra dose of 2 or 4 mg may be taken, preferably at night to minimize sedation.

Spasticity due to neurological disorders: The initial daily dose should not exceed 6 mg given in 3 divided doses. It may be increased stepwise at half-weekly or weekly intervals by 2 to 4 mg. The optimum therapeutic response is generally achieved with a daily dose of between 12 and 24 mg, administered in 3 or 4 equally spaced doses. The daily dose of 36 mg should not be exceeded.

Pediatrics patients: Experience in patients below 18 years of age is limited and the use of Tizanidine in this population is not recommended.

Geriatric patients (65 years of age or older): Experience with the use of Tizanidine in the elderly is limited. Therefore, it is recommended to start treatment at the lowest dose and increases should be done in small steps according to tolerability and efficacy.

Renal impairment: In patients with renal impairment (creatinine clearance <25 mL/min), it is recommended to start treatment at 2 mg once daily. An increase in dosage should be done in small steps according to tolerability and efficacy. If efficacy has to be improved, it is advisable to first increase the strength of the daily dose before increasing the frequency of administration.

Hepatic impairment: Use of Tizanidine in patients with severe hepatic impairment is contraindicated. While Tizanidine is extensively metabolized in the liver, limited data are available in this population. Its use has been associated with a reversible abnormality in liver function tests. Tizanidine should be used with caution in patients with moderate hepatic impairment and treatment should be started with the lowest dose. Afterward, an increase in dosage should be done carefully and according to patient tolerability.

Discontinuation of treatment: If Tizanidine has to be discontinued, the dosage should be slowly down titrated, particularly in patients who have received high doses for a longer period of time to avoid or minimize the risk of rebound hypertension and tachycardia.

With low doses, such as those recommended for the relief of painful muscle spasms, somnolence, fatigue, dizziness, dry mouth, blood pressure decrease, nausea, gastrointestinal disorder and transaminase increase have been reported, usually as mild and transient adverse reactions.

With the higher doses recommended for the treatment of spasticity, the adverse reactions reported with low doses are more frequent and more pronounced, but seldom severe enough to require discontinuation of treatment. In addition, the following adverse reactions may occur: hypotension, bradycardia, muscular weakness, insomnia, sleep disorder, hallucination & hepatitis.

• Psychiatric disorders: Common- Insomnia, sleep disorder.
• Nervous system disorders: Very common- Somnolence, dizziness
• Cardiac disorders: Uncommon- Bradycardia
• Vascular disorders: Common- Hypotension
• Gastrointestinal disorders: Very common- Gastrointestinal disorder, dry mouth; Common- Nausea.
• Musculoskeletal and connective tissue disorders: Very common- Muscular weakness
• General disorders and administration site conditions: Very common- Fatigue
• Investigations: Common- Blood pressure decreased, transaminases increased.

CYP inhibitors: The concomitant use of Tizanidine with moderate CYP1A2 inhibitors is not recommended. Caution should be exercised when Tizanidine is given with drugs known to increase the QT interval.

Hypotension: Hypotension may occur during treatment with Tizanidine and also as a result of drug interactions with CYP1A2 inhibitors and/or antihypertensive drugs. Severe manifestations of hypotension such as loss of consciousness and circulatory collapse have also been observed.

Withdrawal syndrome: Rebound hypertension and tachycardia have been observed after sudden withdrawal of Tizanidine, when it had been used chronically, and/or in high daily dosages, and/or concomitantly with antihypertensive drugs. In extreme cases, rebound hypertension might lead to cerebrovascular accident. Tizanidine should not be stopped abruptly, but rather gradually down titrated.

Hepatic dysfunction: Since hepatic dysfunction has been reported in association with tizanidine, but rarely at daily doses up to 12 mg, it is recommended that liver function tests should be monitored monthly for the first four months in patients receiving doses of 12 mg and higher and in patients who develop clinical symptoms suggestive of hepatic dysfunction, such as unexplained nausea, anorexia or tiredness. Treatment with Tizanidine should be discontinued if serum levels of SGPT or SGOT are persistently above three times the upper limit of the normal range.

Patients with renal impairment: In patients with renal impairment (creatinine clearance <25 mL/min) systemic exposure to tizanidine may increase up to 6 times compared to patient with normal renal function. Therefore, it is recommended to start treatment at 2 mg once daily.

Hypersensitivity reactions: Hypersensitivity reactions including anaphylaxis, angioedema, dermatitis, rash, urticarial, pruritis and erythema have been reported in association with tizanidine. Careful observation of the patient is recommended for one to two days after the first dose is administered. If anaphylaxis or angioedema with anaphylactic shock or difficulty of breathing is observed treatment with Tizanidine should be discontinued immediately and appropriate medical treatment should be instituted.

Driving and using machines: Patients experiencing somnolence, dizziness or any signs or symptoms of hypotension should refrain from activities requiring a high degree of alertness, e.g. driving a vehicle or operating machines.

Concomitant administration of drugs known to inhibit the activity of CYP1A2 may increase the plasma levels of tizanidine. The increased plasma levels of tizanidine may result in overdose symptoms such as QT(c) prolongation. Concomitant administration of drugs known to induce the activity of CYP1A2 may decrease the plasma levels of tizanidine. The decreased plasma levels of tizanidine may reduce the therapeutic effect of Tizanidine.

Observed interactions resulting in a contraindication: Concomitant use of Tizanidine with fluvoxamine or ciprofloxacin, both CYP1A2 inhibitors is contraindicated. Concomitant use of Tizanidine with fluvoxamine or ciprofloxacin resulted in a 33-fold and 10-fold increase in tizanldine AUC, respectively. Clinically significant and prolonged hypotension may result along with somnolence, dizziness and decreased psychomotor performance. The increased plasma levels of tizanidine may result in overdose symptoms such as QT(c) prolongation.

Observed interactions resulting in concomitant use not recommended: Co administration of Tizanidine with other inhibitors of CYP1A2 such as antiarrhythmics (amiodarone, mexiletine, propafenone), cimetidine, fluoroquinolones (enoxacin, pefloxacin, norfloxacin), rofecoxib, oral contraceptives, and ticlopidine is not recommended.

Observed interactions to be considered: Caution should be exercised when Tizanidine is given with drugs known to prolong the QT interval (including but not limited to cisapride, amytriptyline and azithromycin).

Antihypertensives: Concomitant use of Tizanidine with antihypertensives, including diuretics, may occasionally cause hypotension and bradycardia. In some patients rebound hypertension and tachycardia have been observed upon abrupt discontinuation of Tizanidine when concomitantly used with antihypertensive drugs. In extreme cases, rebound hypertension might lead to cerebrovascular accident.

Rifampicin: Concomitant administration of Tizanidine with rifampicin results in 50% decrease in tizanidine concentrations. Therefore, the therapeutic effects of Tizanidine may be reduced during treatment with rifampicin, which may be of clinical significance in some patients. Long term coadministration should be avoided and if co- administration is considered a careful dose adjustment (increase) may be required. 

Cigarette smoke: Administration of Tizanidine in smokers (>10 cigarettes per day) results in about 30% decrease in tizanidine systemic exposure. Long-term therapy with Tizanidine in heavy smokers may require higher doses than the average doses.

Alcohol: While on Tizanidine therapy, alcohol consumption should be minimized or avoided as it may increase the potential for adverse events (e.g. sedation and hypotension). The central nervous system depressant effects of alcohol may be enhanced by Tizanidine.

Anticipated interactions to be considered: Sedatives, hypnotics (e.g. benzodiazepine or baclofen), and another drug such as antihistamines may enhance the sedative action of tizanidine. Tizanidine should be avoided when using with other alpha-2 adrenergic agonists (such as clonidine) because of their potential additive hypotensive effect.

As there is limited experience with the use of Tizanidine in pregnant women, it should not be used during pregnancy unless the benefit clearly outweighs the risk.

Animal data: Reproduction studies performed in rats and rabbits did not show evidence of teratogenicity. In rats, dose levels of 10 and 30 mg/kg/day increased gestation duration. Prenatal and postnatal pup loss was increased and development retardation occurred. At these doses, dams showed marked signs of muscle relaxation and sedation. Based on body surface area, these doses were 2.2 and 6.7 times the maximum recommended human dose of 0.72 mg/kg/day.

Lactation: Small amounts of tizanidine are excreted in rat milk. Since no human (fata are available Tizanidine should not be given to women who are breast-feeding.

Females and males of reproductive potential: Pregnancy testing:  Sexually-active females of reproductive potential are recommended to have a pregnancy test prior to starting treatment with Tizanidine.

Contraception: Females of reproductive potential should be advised that animal studies have been performed showing Tizanidine to be harmful to the developing fetus. Sexually-active females of reproductive potential are recommended to use effective contraception (methods that result in less than 1 % pregnancy rates) when using Tizanidine during treatment and for 1 day after stopping treatment with Tizanidine.

Fertility: Animal data: No impairment of fertility was observed in male rats at a dose of 10 mg/kg/day, and in female rats at a dose of 3 mg/kg/day. Fertility was reduced in male rats receiving 30 mg/kg/day and in female rats receiving 10 mg/kg/day. Based on body surface area, these doses were 6.7 and 2.2 times the maximum recommended human dose of 0.72 mg/kg. At these doses, maternal behavioral effects and clinical signs were observed including marked sedation, weight loss and ataxia.

Renal impairment (creatinine clearance <25 mL/min): Maximal mean plasma levels were found to be twice as high as in normal volunteers, and the terminal half-life was prolonged to approximately 14 hours, resulting in much higher (approximately 6-fold on average) AUC values.

Hepatic impairment: No specific studies were conducted in this population. As tizanidine is extensively metabolized in the liver by the CYP1A2 enzyme, hepatic impairment may increase its systemic exposure. Tizanidine is contraindicated in patients with severe hepatic impairment.

Geriatrics (65 years of age and older): Pharmacokinetic data in this population are limited.

Gender: Gender has no clinically significant effect on the pharmacokinetics of tizanidine.

Ethnicity: The impact of ethnic sensitivity and race on the pharmacokinetics of tizanidine has not been studied.

In the few reports of Tizanidine overdosage received, recovery was uneventful, including by a patient who ingested 400 mg Tizanidine. Nausea, vomiting, hypotension, QT(c) prolongation, dizziness, somnolence, miosis, restlessness, respiratory distress, coma. It is recommended to eliminate the ingested drug by repeated administration of high doses of activated charcoal. Forced diuresis is expected to accelerate the elimination of Tizanidine. Further treatment should be symptomatic.

Store in a dry place below 30°C. Tizanidine must be kept out of the reach and sight of children.

Diltiazem Hydrochloride film coated tablet is used for the prophylaxis and treatment of chronic stable (classical) and vasopastic angina pectoris and has also been used alone or in combination in the management of hypertension, also, Diltiazem is effective in myocardial infarction, coronary artery spasm, arrhythmias, Raynaud's phenomenon, oesophageal motility disorder and migraine.

Calcium-channel blockers

Diltiazem is a calcium-channel blocker with peripheral and coronary vasodilator properties. It lowers blood pressure and has some effect on cardiac conduction. Diltiazem interferes with the influx of calcium ions through the channels of active cell membranes.

Adult: The usual dose of Diltiazem Hydrochloride film coated tablet is 60 mg thrice daily. However patient's response may vary and dosage requirements can differ significantly between individual patients. If necessary, the divided dose may be increased to 180-300 mg/day. Dosage may be started as 30 mg four times daily and increasing at 1 to 2 days intervals until the optimum response is achieved. Higher doses upto 480 mg/day have been used with benefit in some patients especially in unstable angina. Elderly and patients with impaired hepatic or renal function: The recommended starting dose is 60 mg twice daily. The heart rate should be measured regularly and the dose should not be increased if the heart rate falls below 50 beats per minute.

Children: Not recommended.

With Diltiazem headache, ankle oedema, hypertension, dizziness, flushing, rashes (toxic erythema), nausea and Gl disturbances may occur. Transient elevation in liver enzyme values and occasionally hepatitis have been reported. Diltiazem may depress cardiac conduction and has occasionally led to AV block, bradycardia and rarely asystoleor sinus arrest.

Diltiazem is contraindicated to the patients of severe bradycardia, sick sinus syndrome, pregnancy, second or third degree AV block.

Diltiazem should be used with care in patients with lesser degrees of AV block or bradycardia; also in patients with impaired left ventricular function. Caution should be required in patients with impaired liver or kidney function.

Diltiazem Hydrochloride film coated tablet is used for the prophylaxis and treatment of chronic stable (classical) and vasopastic angina pectoris and has also been used alone or in combination in the management of hypertension, also, Diltiazem is effective in myocardial infarction, coronary artery spasm, arrhythmias, Raynaud's phenomenon, oesophageal motility disorder and migraine.

Calcium-channel blockers

Diltiazem is a calcium-channel blocker with peripheral and coronary vasodilator properties. It lowers blood pressure and has some effect on cardiac conduction. Diltiazem interferes with the influx of calcium ions through the channels of active cell membranes.

Adult: The usual dose of Diltiazem Hydrochloride film coated tablet is 60 mg thrice daily. However patient's response may vary and dosage requirements can differ significantly between individual patients. If necessary, the divided dose may be increased to 180-300 mg/day. Dosage may be started as 30 mg four times daily and increasing at 1 to 2 days intervals until the optimum response is achieved. Higher doses upto 480 mg/day have been used with benefit in some patients especially in unstable angina. Elderly and patients with impaired hepatic or renal function: The recommended starting dose is 60 mg twice daily. The heart rate should be measured regularly and the dose should not be increased if the heart rate falls below 50 beats per minute.

Children: Not recommended.

With Diltiazem headache, ankle oedema, hypertension, dizziness, flushing, rashes (toxic erythema), nausea and Gl disturbances may occur. Transient elevation in liver enzyme values and occasionally hepatitis have been reported. Diltiazem may depress cardiac conduction and has occasionally led to AV block, bradycardia and rarely asystoleor sinus arrest.

Diltiazem is contraindicated to the patients of severe bradycardia, sick sinus syndrome, pregnancy, second or third degree AV block.

Diltiazem should be used with care in patients with lesser degrees of AV block or bradycardia; also in patients with impaired left ventricular function. Caution should be required in patients with impaired liver or kidney function.

Third generation Cephalosporins

Ceftazidime is a semisynthetic, broad-spectrum, beta-lactam antibiotic for parenteral administration. Ceftazidime is bactericidal in action exerting its effect by inhibition of enzymes responsible for cell-wall synthesis. A wide range of gram-negative organisms is susceptible to ceftazidime in vitro, including strains resistant to gentamicin and other aminoglycosides. In addition, ceftazidime has been shown to be active against gram-positive organisms. It is highly stable to most clinically important beta-lactamases, plasmid or chromosomal, which are produced by both gram-negative and gram-positive organisms and, consequently, is active against many strains resistant to ampicillin and other cephalosporins.

The usual adult dosage is 1 gram administered intravenously or intramuscularly every 8 to 12 hours. The dosage and route should be determined by the susceptibility of the causative organisms, the severity of infection and the condition, and renal function of the patient.

Ceftazidime is to be used by the parenteral route, the dosage depending upon the severity, sensitivity & type of infections and the age, weight & renal function of the patient.

Adults: The adult dosage range for ceftazidime is 1 to 6 gm per day 8 or 12 hourly (IM/IV) in the majority of infections, 1 gm 8 hourly or 2 gm 12 hourly should be given.

• In urinary tract infections and many less serious infections: 500 mg or 1 gm 12 hourly is usually adequate.
• In severe infections, especially immunocompromised patients, including those with neutropenia: 2 gm 8 or 12 hourly should be administered. When used as a prophylactic agent in prostatic surgery 1 gm should be given at the induction of anesthesia. A second dose should be considered at the time of catheter removal.

Elderly: In view of the reduced clearance of Ceftazidime in acutely ill elderly patients, the daily dosage should not normally exceed 3 gm, especially in those over 80 years of age.

• Cystic fibrosis: In fibrocystic adults with normal renal function who have pseudomonal lung infections, high doses of 100 to 150 mg/kg/day as three divided doses should be used.

Infants and Children: The usual dosage range for children aged over two months is 30 to 100 mg/kg/day, given as two or three divided doses. Doses up to 150 mg/kg/day (maximum 6 gm daily) in three divided doses may be given to infected immunocompromised or fibrocystic children or children with meningitis.

Neonates and Children up to 2 months of age: The usual dosage range is 25 to 60 mg/kg/day as two divided doses.

Ceftazidime may be given intravenously or by deep IM injection into a large muscle mass such as the upper outer quadrant of the gluteus maximus or lateral proof of the thigh. Intra-arterial administration should be avoided. For IV/IM administration, Ceftazidime should be reconstituted with the supplied Sterile Water for Injection.

The most common side-effects are local reactions following IV injection and allergic and gastrointestinal reactions. Hypersensitivity reactions are pruritus, rash, and fever. Angioedema and anaphylaxis have been reported very rarely. Gastrointestinal symptoms are diarrhea, nausea, vomiting, and abdominal pain. Central nervous system reactions included headache, dizziness, and paresthesia.

Ceftazidime is contraindicated in patients who have shown hypersensitivity to Ceftazidime or the cephalosporin group of antibiotics.

The total daily dosage should be reduced when Ceftazidime is administered to patients with renal insufficiency. Ceftazidime should be prescribed with caution in individuals with a history of gastrointestinal disease, particularly colitis.

Pregnancy: No adequate and well-controlled studies in pregnant women have been conducted with Ceftazidime. Because animal reproduction studies are not always predictive of human response this drug should be used during pregnancy only if clearly needed.

Lactation: Ceftazidime is excreted in human milk in low concentrations. Because many drugs are excreted in human milk and because the safety of the component of the injections in nursing infants has not been established, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Impaired Renal Function: Ceftazidime is excreted by the kidneys, almost exclusively by glomerular filtration. Therefore, in patients with impaired renal function (glomerular filtration rate <50 mL/min), it is recommended that the dosage of ceftazidime be reduced to compensate for its slower excretion. In patients with suspected renal insufficiency, an initial loading dose of 1 gram of Ceftazidime may be given. An estimate of GFR should be made to determine the appropriate maintenance dosage.

Dosage in peritoneal dialysis: Ceftazidime may also be used in peritoneal dialysis and continuous ambulatory peritoneal dialysis (CAPD). As well as using Ceftazidime intravenously, it can be incorporated into the dialysis fluid (usually 125 to 250 mg for 2L of dialysis fluid).

Impaired Hepatic Function: No adjustment in dosage is required for patients with hepatic dysfunction.

Ceftazidime overdosage has occurred in patients with renal failure. Reactions have included seizure activity, encephalopathy, asterixis, neuromuscular excitability, and coma. Patients who receive an acute overdosage should be carefully observed and given supportive treatment.

Single-dose vial Administration Amount of WFI to be added: 250 mg IM in 1.5 ml, 250 mg IV in 5 ml, 500 mg IM in 1.5 ml, 500 mg IV in 5 ml and 1 g IM in 3 ml, 1 g IV in 10 ml.

Store below 25°C, protected from light and moisture. Reconstituted solutions are stable for up to 24 h if stored between 2°-8°C.

Ophthalmic antibacterial drugs

Like other aminoglycosides, the bactericidal activity of Tobramycin is taken up into sensitive bacterial cells by an active transport process. Within the cell Tobramycin bind to the 30s, and to some extent to the 50s subunits of the bacterial ribosome, inhibiting protein synthesis and generating errors in the transcription of the genetic code. The manner in which cell death is brought about is imperfectly understood, and other mechanisms may contribute, including effects on membrane permeability.

Ophthalmic ointment:

• In mild to moderate infection, apply a small amount 2-3 times daily into the conjunctival sac(s).
• In severe cases of infection, apply a small amount 3-4 times daily into the conjunctival sac(s) until improvement is obtained, then reduce the dose gradually.

Ophthalmic solution:

• In mild to moderate infections: Instill 1or 2 drops into the affected eye(s) every 4 hours.
• In severe infections: Instill 2 drops into the affected eye(s) every hour until improvement is observed.

Pediatric use: Safety and effectiveness in children below the age of 1 year have not been established.

The most frequent side effect of Tobramycin ophthalmic solution is localized ocular toxicity, conjunctival erythema, hypersensitivity including lid itching and swelling.

It is contraindicated in patients who are hypersensitive to Tobramycin or any of the ingredients of the preparation.

Minor sensitivity may occur to topically applied aminoglycosides in some patients. If a sensitivity reaction occurs, discontinue use. Prolonged use may result in overgrowth of nonsusceptible organisms and fungi.

Care should be exercised when tobramycin is given to patients receiving other drugs with neuromauscular blocking agents or ototoxic.

Pregnancy Category B. There are no adequate and well-controlled studies in pregnant women. This drug should only be used during pregnancy, if the potential benefits outweigh the possible risk to the fetus. Drug may excreted into human milk. A decision should be made whether to discontinue nursing or to taking the drug.

Sign and symptoms of overdose may be similar to side effects as described above.

Protect from light, store in cool (below 25°C) & dry place. Keep out of reach of children. Used within 4 weeks after first opening.

Aminoglycosides

Tobramycin interferes with bacterial protein synthesis by binding to 30S and 50S ribosomal subunits, resulting in a defective bacterial cell membrane.

The recommended dosage for, both adult and paediatric patients, 6 years of age and older, is one single-use ampoule (300 mg) administered b.i.d for 28 days. Dosage is not adjusted by weight.

The doses should be taken as close to 12 hours apart as possible; they should not be taken less than 6 hours apart.

If you are taking several medications, the recommended order is as follows: bronchodilator first, followed by chest physiotherapy, then other inhaled medications and finally Tobramycin.

You should take Tobramycin in repeated cycles of 28 days on drug, followed by 28 days off drug. You should take Tobramycin twice a day during the 28 day period on drug.

Inhaled Tobramycin is generally well-tolerated. Voice alterations and tinnitus are more common in the on-drug periods. However all the episodes are transient and resolved without discontinuation of the regimen. Others like dizziness and increase in serum creatinine were similar to those occurring with placebo.

Tobramycin is contraindicated in patients with a known hypersensitivity to any aminoglycoside.

It should be used with care in patients with known or suspected renal, auditory, vestibular, or neuromuscular dysfunction. Patients receiving concomitant aminoglycoside therapy should be monitored as clinically appropriate. It must be used with caution in patients with ototoxicity and nephrotoxicity. Discuss the use of Tobramycin with your doctor if you have kidney problems or changes in hearing. Respirator Solution must only be used by inhalation from a nebulizer and must not be injected or swallowed.

Patients taking Tobramycin concomitantly with beta agonists, inhaled corticosteroids, other anti pseudomonal antibiotics or parenteral aminoglycosides demonstrated adverse experience profiles.

If you are a nursing mother, pregnant or want to become pregnant, ask your doctor about the possibility of Tobramycin causing any harm.

Renal Impairment: Inhalation: Dosage adjustment needed.

Symptoms: Nephrotoxicity, auditory and vestibular toxicity (e.g. dizziness, tinnitus, vertigo, loss of high-tone hearing acuity), neuromuscular blockade or resp failure.

Management: Initiate resuscitative measures if resp paralysis occurs. Ca salts may be given to reverse neuromuscular blockade. Haemodialysis or peritoneal dialysis will help remove drug serum levels.

Store under refrigeration at 2-8° C, and protected from light. Slight color change when unrefrigerated do not indicate any change in the quality of the product. The preparation must not be used if it is cloudy, particles appear in the solution or has been stored at room temperature for over 28 dyas. For use only under the prescription of a registered physician. Do not use Tobasol® beyond the expiration date stamped on the ampoule.

This sterile Eye Suspension is indicated for steroid-responsive inflammatory ocular conditions for which a corticosteroid is indicated and where bacterial infection or a risk of bacterial ocular infection exists.

Ophthalmic steroid - antibiotic combined preparations

Like other amino-glycosides, the bactericidal activity of Tobramycin is accomplished by specific inhibition of normal protein synthesis in susceptible bacteria, but at the present time, very little is known about this action. It is thought that inhibition of protein synthesis is due to an action on ribosome that causes bacterial misreading of messenger RNA. The action of Dexamethasone is to inhibit the phospholipase A2, the first step in prostaglandin synthesis. Also Dexamethasone inhibits the chemo-tactic infiltration of neutrophils into the site of inflammation. The result is that its anti-inflammatory activity is 25 times greater and its overall therapeutic effectiveness 8-10 times greater than that of hydrocortisone.

Insert 1 drop into the conjunctival sac 3-5 times per day. During the initial 24 to 48 hours, the dosage may be increased to 1 drop every 2 hours.

The most frequent side effects to topical ocular Tobramycin are localized ocular toxicity and hypersensitivity, including lid itching and swelling and conjuntival erythema. The reactions due to the steroid component are elevation of intraocular pressure (IOP) with possible development of glaucoma and infrequent optic nerve damage, posterior subcapsule cataract formation.

Epithelial herpes simplex keratitis (dendritic keratitis), vaccinia, varicella and other viral disease of the cornea and conjunctiva. Mycobacterial infections of the eye caused by, but not limited to, acid-fast bacilli such as Mycobacterium tuberculosis, Mycobacterium leprae, or Mycobacterium avium. Fungal diseases of ocular structures. Untreated purulent infection of the eye. Hypersensitivity to any component of the medication.

• In mild to moderate infections: Instill 1or 2 drops into the affected eye(s) every 4 hours.
• In severe infections: Instill 2 drops into the affected eye(s) every hour until improvement is observed.

Pediatric use: Safety and effectiveness in children below the age of 1 year have not been established.

The most frequent side effect of Tobramycin ophthalmic solution is localized ocular toxicity, conjunctival erythema, hypersensitivity including lid itching and swelling.

It is contraindicated in patients who are hypersensitive to Tobramycin or any of the ingredients of the preparation.

Minor sensitivity may occur to topically applied aminoglycosides in some patients. If a sensitivity reaction occurs, discontinue use. Prolonged use may result in overgrowth of nonsusceptible organisms and fungi.

Care should be exercised when tobramycin is given to patients receiving other drugs with neuromauscular blocking agents or ototoxic.

Pregnancy Category B. There are no adequate and well-controlled studies in pregnant women. This drug should only be used during pregnancy, if the potential benefits outweigh the possible risk to the fetus. Drug may excreted into human milk. A decision should be made whether to discontinue nursing or to taking the drug.

Sign and symptoms of overdose may be similar to side effects as described above.

Protect from light, store in cool (below 25°C) & dry place. Keep out of reach of children. Used within 4 weeks after first opening.

Ophthalmic antibacterial drugs

Like other aminoglycosides, the bactericidal activity of Tobramycin is taken up into sensitive bacterial cells by an active transport process. Within the cell Tobramycin bind to the 30s, and to some extent to the 50s subunits of the bacterial ribosome, inhibiting protein synthesis and generating errors in the transcription of the genetic code. The manner in which cell death is brought about is imperfectly understood, and other mechanisms may contribute, including effects on membrane permeability.

Ophthalmic ointment:

• In mild to moderate infection, apply a small amount 2-3 times daily into the conjunctival sac(s).
• In severe cases of infection, apply a small amount 3-4 times daily into the conjunctival sac(s) until improvement is obtained, then reduce the dose gradually.
