Glucocorticoids

Deflazacort provides anti-inflammatory action by inhibiting Phospholipase A2 enzyme which is responsible for prostaglandin synthesis. Besides Deflazacort decreases the release of certain chemicals that are important in the immune system. By decreasing the release of these chemicals Deflazacort provides immunosuppressive action.

Adults-

• For acute disorders: Up to 120 mg/day Deflazacort may need to be given initially. Maintenance doses in most conditions are within the range of 3-18 mg/day.
• Rheumatoid arthritis: The maintenance dose is usually within the range of 3-18 mg/day. The smallest effective dose should be used and increased if necessary.
• Bronchial asthma: In the treatment of an acute attack, high doses of 48-72 mg/day may be needed depending on severity and gradually reduced once the attack has been controlled. For maintenance in chronic asthma, doses should be titrated to the lowest dose that controls symptoms.
• Other conditions: The dose of Deflazacort depends on clinical need titrated to the lowest effective dose for maintenance. Starting doses may be estimated on the basis of ratio of 5 mg prednisone or prednisolone to 6 mg.

Children: There has been limited exposure of children to Deflazacort in clinical trials. In children, the indications for glucocorticoids arethe same as for adults, but it is important that the lowest effective dosage is used. Alternate day administration may be appropriate. Doses of Deflazacort usually lie in the range 0.25-1.5 mg/kg/day.

The following ranges provide general guidance:

• Juvenile chronic arthritis: The usual maintenance dose is between 0.25-1.0 mg/kg/day.
• Nephrotic syndrome: Initial dose of usually 1.5 mg/kg/day followed by down titration according to clinical need.
• Bronchial asthma: On the basis of the potency ratio, the initial dose should be between 0.25-1.0 mg/kg on alternate days.

Deflazacort withdrawal: In patients who have received more than physiological doses of systemic corticosteroids (approximately 9 mg per day or equivalent) for greater than 3 weeks, withdrawal should not be abrupt. How dose reduction should be carried out depends largely on whether the disease is likely to relapse as the dose of systemic corticosteroids is reduced.

GI disturbances, musculoskeletal, endocrine, neuropsychiatric, ophthalmic, fluid and electrolyte disturbances; susceptible to infection, impaired healing, hypersensitivity, skin atrophy, striae, telangiectasia, acne, myocardial rupture following recent Ml, thromboembolism.

Hypersensitivity to or any of the ingredients. Patients receiving live virus immunization.

The following clinical conditions require special caution and frequent patient monitoring is necessary-

• Cardiac disease or congestive heart failure (except in the presence of active rheumatic carditis), hypertension, thromboembolic disorders. Glucocorticoids can cause salt and water retention and increased excretion of potassium. Dietary salt restriction and potassium supplementation may be necessary.
• Gastritis or oesophagitis, diverticulitis, ulcerative colitis if there is the probability of impending perforation, abscess or pyogenic infections, fresh intestinal anastomosis, active or latent peptic ulcer.
• Diabetes mellitus or family history, osteoporosis, myasthenia gravis, renal insufficiency.
• Emotional instability or psychotic tendency, epilepsy.
• Previous corticosteroid-induced myopathy.
• Liver failure.
• Hypothyroidism and cirrhosis, which may increase the glucocorticoid effect.
• Ocular herpes simplex because of possible corneal perforation.

Deflazacort is metabolized in the liver. It is recommended to increase the maintenance dose of Deflazacort if drugs which are liver enzyme inducers are co-administered, e.g. rifampicin, rifabutin, carbamazepine, phenobarbitone, phenytoin, primidone and aminoglutethimide. For drugs which inhibit liver enzymes, (e.g. ketoconazole) it may be possible to reduce the maintenance dose of Deflazacort.

Pregnancy: Deflazacort does cross the placenta. However, when administered for prolonged periods or repeatedly during pregnancy, corticosteroids may increase the risk of intrauterine growth retardation. As with all drugs, corticosteroids should only be prescribed when the benefits to the mother and child outweigh the risks.

Nursing Mother: Corticosteroids are excreted in breast milk, although no data are available for Deflazacort. Doses of up to 50 mg daily of Deflazacort are unlikely to cause systemic effects in the infant. Infants of mothers taking higher doses than this may have a degree of adrenal suppression but the benefits of breastfeeding are likely to outweigh any theoretical risk.

Hepatic Impairment: In patients with hepatic impairment, blood levels of may be increased. Therefore the dose of Deflazacort should be carefully monitored and adjusted to the minimum effective dose.

Renal Impairment: In renally impaired patients, no special precautions other than those usually adopted in patients receiving glucocorticoid therapy are necessary.

Elderly: In elderly patients, no special precautions other than those usually adopted in patients receiving glucocorticoid therapy are necessary. The common adverse effects of systemic corticosteroids may be associated with more serious consequences in old age.

Store in a cool (below 25°C) and dry place, protected from light & moisture. Keep out of the reach of children.

Ketotifen is indicated in the following conditions-

• For the prophylactic treatment of bronchial asthma.
• Symptomatic treatment of allergic conditions including rhinitis and conjunctivitis.
• For alleviating the complications of itching, pain and tenderness associated with neurofibroma.
• Symptomatic treatment of allergy such as hayfever, urticaria.

Cromoglycate & related drugs

Ketotifen has anti-allergic properties and has been used similarly, to sodium chromoglycate in the prophylactic treatment of asthma. It also has the properties of an antihistamine. Ketotifen possesses marked anti-anaphylactic properties and is effective in preventing an asthmatic attacks. Ketotifen exerts as sustained inhibitory effect on histamine reactions, which can be clearly dissociated from its anti-anaphylactic properties. Experimental investigations in asthmatic subjects have shown that Ketotifen is as effective orally as a selective mast cell stabilizer administered by inhalation. Antihistamines were ineffective in those tests. The effectiveness of Ketotifen has been studied in long-term clinical trials. Asthma attacks were reduced in number, severity and duration and in some cases, the patients were completely freed from attacks. Progressive reduction of corticosteroids and/or bronchodilators was also possible. The prophylactic activity of Ketotifen may take several weeks to become fully established. Ketotifen will not abort established attacks of asthma.

Adults: 1 mg twice daily with food. If necessary the dose may be increased to 2 mg twice daily in severe cases.

Children above 3 years: 1 mg twice daily with food. Patients known to be easily sedated should begin treatment with 0.5 to 1 mg at night for the first few days or as directed by the physician.

Use in elderly: Same as adult dose or as advised by the physician.

Drowsiness and in isolated cases, dry mouth and slight dizziness may occur at the beginning of treatment but usually disappear spontaneously after a few days.

A reversible fall in the platelet count has been observed in a few patients receiving Ketotifen concomitantly with oral antidiabetic agent and it has been suggested that this combination should therefore be avoided. Although there is no evidence of any teratogenic effect, recommendations for Ketotifen in pregnancy or when breast feeding can not be given.

It is important to continue the previous treatment for a minimum of two weeks after starting Ketotifen to avoid the possibility of exacerbation of asthma. This applies specially to systemic corticosteroids and ACTH because of the possible existence of adrenocortical insufficiency in steroid dependent patient. If inter current infection occurs, Ketotifen treatment must be supplemented by specific antimicrobial therapy. During the first day of treatment with Ketotifen, reactions may be impaired and patients should be warned not to take charge of vehicle or machinery until the effect of Ketotifen treatment on the individual is known. Patients should be advised to avoid alcoholic drinks. Ketotifen may potentiate the effects of sedatives, hypnotics, antihistamines and alcohol.

Ketotifen may potentiate the effects of sedatives, hypnotics, antihistamines and alcohols. A reversible fall in the platelet count has been observed in a few patients receiving Tifen concomitantly with oral antidiabetic agents and it has been suggested that this combination should therefore be avoided.

Although there is no evidence of any teratogenic effect, Ketotifen in pregnancy and lactation is not recommended.

The reported features of overdosage include confusion, drowsiness, headache, bradycardia, respiratory depression etc. should be watched for. Elimination of the drug with gastric lavage or emessis is recommended. Otherwise, general supportive treatment is all that is required shall be instituted.

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

Cytotoxic immunosuppressants

Azathioprine antagonizes purine metabolism and may inhibit synthesis of DNA, RNA, and proteins. It may also interfere with cellular metabolism and inhibit mitosis. Its mechanism of action is likely due to incorporation of thiopurine analogues into the DNA structure, causing chain termination and cytotoxicity.

Renal Homotransplantation: The dose of Azathioprine required to prevent rejection and minimize toxicity will vary with individual patients; this necessitates careful management. The initial dose is usually 3 to 5 mg/kg daily, beginning at the time of transplant. Azathioprine is usually given as a single daily dose on the day of, and in a minority of cases 1 to 3 days before, transplantation. Dose reduction to maintenance levels of 1 to 3 mg/kg daily is usually possible. The dose of Azathioprine should not be increased to toxic levels because of threatened rejection. Discontinuation may be necessary for severe hematologic or other toxicity, even if rejection of the homograft may be a consequence of drug withdrawal.

Rheumatoid Arthritis: Azathioprine is usually given on a daily basis. The initial dose should be approximately 1.0 mg/kg (50 to 100 mg) given as a single dose or on a twice-daily schedule. The dose may be increased, beginning at 6 to 8 weeks and thereafter by steps at 4-week intervals, if there are no serious toxicities and if initial response is unsatisfactory. Dose increments should be 0.5 mg/kg daily, up to a maximum dose of 2.5 mg/kg per day. Therapeutic response occurs after several weeks of treatment, usually 6 to 8; an adequate trial should be a minimum of 12 weeks. Patients not improved after 12 weeks can be considered refractory. Azathioprine may be continued long-term in patients with clinical response, but patients should be monitored carefully, and gradual dosage reduction should be attempted to reduce risk of toxicities.

Maintenance therapy should be at the lowest effective dose, and the dose given can be lowered decrementally with changes of 0.5 mg/kg or approximately 25 mg daily every 4 weeks while other therapy is kept constant. The optimum duration of maintenance Azathioprine has not been determined. Azathioprine can be discontinued abruptly, but delayed effects are possible.

Opportunistic infections especially in transplant patients receiving concomitant other immunosuppressants. Bone marrow depression, leucopenia, thrombocytopenia, nausea. Uncommonly, anaemia, hypersensitivity reactions, cholestasis, pancreatitis.

Azathioprine should not be used for treating rheumatoid arthritis in pregnant women.Patients with rheumatoid arthritis previously treated with alkylating agents (cyclophosphamide, chlorambucil, melphalan, or others) may have a prohibitive risk of malignancy if treated with Azathioprine

Monitor FBC wkly during 1st 8 wk of therapy especially with high dose or severe renal/hepatic impairment. Inherited deficiency of thiopurine methyltransferase enzyme. Avoid excessive sun/UV exposure.

Metabolism inhibited by allopurinol. Reduces the neuromuscular blockade of curare, tubocurarine but potentiates that of succinylcholine.

Pregnancy Category D. There is positive evidence of human foetal risk, but the benefits from use in pregnant women may be acceptable despite the risk

Use In Renal Dysfunction: Relatively oliguric patients, especially those with tubular necrosis in the immediate postcadaveric transplant period, may have delayed clearance of Azathioprine or its metabolites, may be particularly sensitive to this drug, and are usually given lower doses. Procedures for proper handling and disposal of this immunosuppressive antimetabolite drug should be considered. Several guidelines on this subject have been published.25-31 There is no general agreement that all of the procedures recommended in the guidelines are necessary or appropriate.

Azathioprine should be stored at 15 to 25° C in a dry place and protected from light.

This is indicated for the treatment and prevention of zinc and vitamin B deficiencies.

Specific mineral & vitamin combined preparations

Zinc is vital for many biological functions such as immunity enhancement, wound healing, digestion, reproduction, physical growth and mental development. Zinc supports normal growth and development during pregnancy, childhood, and adolescence. Zinc also has some antioxidant properties. Zinc is used to treat ADHD (Attention Deficit Hyper-activity Disorder) in children. In adult, due to zinc deficiency loss of appetite, poor sense of taste and smell, tendency towards depression, white marks on fingernails, frequent infections, low fertility, prostate problems, mental problems, poor wound healing, a poor immune system, diarrhoea, mental lethargy, rough skin and weight loss may occur.

B-Vitamins are needed to release energy from food. They play an important role in ensuring healthy brain and nerve function, healthy red blood cells formation in children & adults. They are specially needed for healthy growth and development of children. B-Vitamin deficiencies in adult cause profound fatigue and various types of neurologic manifestations, which may include weakness, poor balance, confusion, irritability, memory loss, nervousness, tingling of the limbs and loss of coordination. Additional symptoms of vitamin B deficiency are sleep disturbances, nausea, poor appetite, frequent infections, and skin lesions.

Syrup-

• Adults: 10 ml (2 teaspoonful) 2 to 3 times daily or as recommended by the physician.
• Children: 10 ml (2 teaspoonful) 1 to 3 times daily or as recommended by the physician.
• Infants: 5 ml (1 teaspoonful) 1 to 2 times daily or as recommended by the physician.

Tablet-

• Adults & Children over 30 kg: 1 to 2 tablets 2 to 3 times daily or as recommended by the physician.

This is generally well tolerated. However, a few side effects like nausea, vomiting, diarrhoea & stomach upset may occur. Side effects have been reported with specific vitamins but generally at levels substantially higher than recommended doses.

Vitamin B Complex & Zinc is contraindicated in patients with a known hypersensitivity to any of the ingredients of this product.

In acute renal failure, zinc accumulation may occur, so dosage adjustment is needed. This is not intended for the treatment of severe specific deficiencies.

Concomitant intake of tetracyclines and zinc may decrease the Gl absorption and serum levels of tetracyclines. Similarly concomitant administration of zinc and fluroquinolones may decrease the Gl absorption and serum  levels of some fluroquinolones. Coadministration of Niacin and HMG-CoA reductase inhibitors (eg. lovastatin) may result mayopathy and rhabdomyolysis. Pyridoxine reduces levodopa's effectiveness by increasing its peripheral metabolism. Co-administration of pyridoxine with phenytoin may decrease serum levels of phenytoin.

This is recommended in pregnancy and lactation.

In case of overdosage, initially epigastric pain, diarrhoea and vomiting can occur. In that case, one should seek emergency medical attention. Initially, an emetic should be given and then gastric lavage and general supportive measures should be employed.

Store in a cool & dry place, protected from light. Keep all medicines out of reach of children.

Bromfenac is indicated for the treatment of postoperative inflammation and the reduction of ocular pain in patients who have undergone cataract extraction

Ophthalmic Non-Steroid drugs

Bromfenac is a nonsteroidal anti-inflammatory drug (NSAID). The mechanism of anti-inflammatory activity is thought to be due to its ability to block prostaglandin synthesis by inhibiting cyclooxygenase 1 and 2. Prostaglandins have been shown in many animal models to be mediators of certain kinds of intraocular inflammation. In studies performed in animal eyes, prostaglandins have been shown to produce disruption of the blood-aqueous humor barrier, vasodilation, increased vascular permeability, leukocytosis and increased intraocular pressure.

Adults: 1 drop to the problem eye 2 times a day; treatment should start 24 hours after surgery and should continue for 2 weeks

Children: Use and dose must be determined by the doctor.

Pediatric Use: Safety and efficacy in pediatric patients below the age of 18 have not been established yet.

The most commonly reported adverse reactions following use of Bromfenac after cataract surgery include: abnormal sensation in eye, conjunctival hyperemia, eye irritation (including burning/stinging), eye pain, eye pruritus, eye redness, headache and iritis. These events were reported in 2-7% of patients

Bromfenac ophthalmic solution is contraindicated in patients with known hypersensitivity to any ingredients of the formulation.

All topical NSAIDs may slow or delay healing. Topical corticosteroids are also known to slow or delay healing. Concomitant use of topical NSAIDs and topical steroids may increase the potential for healing problems. It is recommended that Bromfenac ophthalmic solution be used with caution in patients with known bleeding tendencies or who are receiving other medications which may prolong bleeding time. Bromfenac ophthalmic solution should not be administered while wearing contact lenses.

Bromfenac ophthalmic solution contains Sodium Sulfite, a compound that may cause allergic-type reactions including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people. The overall prevalence of sulfite sensitivity in the general population is unknown and probably low. Therefore, caution should be used when treating individuals who have previously exhibited sensitivities to these drugs.

Pregnancy Category C. This drug should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Caution should be exercised when Bromfenac ophthalmic solution is administered to a nursing mother.

Keep out of the reach of children. Store in a cool, dry place, away from heat and direct light.  Do not use more than 4 weeks after opening.

Third generation Cephalosporins

Ceftibuten is the dihydrate salt of Ceftibuten, is a semi-synthetic Cephalosporin antibiotic for oral administration. Ceftibuten exerts its bactericidal action by binding to essential target proteins of the bacterial cell wall. This binding leads to inhibition of cell-wall synthesis.

Nausea, headache, diarrhea, dyspepsia, dizziness, abdominal pain, vomiting.

Ceftibuten is contraindicated in patients with known allergy to the cephalosporin group of antibiotics.

As with other broad-spectrum antibiotics, prolonged treatment may result in the possible emergence and overgrowth of resistant organisms. Careful observation of the patient is essential. The dose of Ceftibuten may require adjustment in patients with varying degrees of renal insufficiency. Ceftibuten should be prescribed with caution to individuals with a history of gastrointestinal disease, particularly colitis.

Theophylline & Antacid do not alter the pharmacokinetic profile of Ceftibuten. Ranitidine increases the Cmax & AUC of Ceftibuten.

Pregnancy Category B. There are no controlled data on the use of Ceftibuten in pregnant women. Ceftibuten should be used in pregnancy only when the benefit clearly outweighs the risk. It is not known whether Ceftibuten (recommended dosage) is excreted in human milk. Because many drugs are excreted in human milk, caution should be excercised when Ceftibuten is administered to nursing women.

Renal Impairment-

• CrCl 5 to 29 ml/min: 2.25 mg/kg or 100 mg orally once a day

Cilostazol is indicated for the reduction of symptoms of intermittent claudication, as indicated by an increased walking distance.

Peripheral Vasodilator drugs: Intermittent Claudication

Cilostazol is a preparation of Cilostazol which is a quinolinone derivative. The mechanism of action is to specifically inhibit cellular phosphodiesterase III (PDE III) and suppress cAMP degradation with a resultant increase in cAMP in platelets and blood vessels, leading to inhibition of platelet aggregation and vasodilation.

The recommended dosage of Cilostazol is 100 mg bid, taken at least half an hour before or two hours after breakfast and dinner. A dose of 50 mg bid should be considered during coadministration of Fluconazole, Ketoconazole, Itraconazole, Erythromycin, Clarithromycin, Fluvoxamine, Fluoxetine, Nefazodone, Sertraline and Diltiazem.

Pediatric use: The safety and effectiveness of Cilostazol in pediatric patients have not been established.

The most common side effects are headache, diarrhoea, vomiting, leg cramps, rash etc. The less frequent side effects are anorexia and edema.

Cilostazol is contraindicated in patients with congestive heart failure of any severity. Cilostazol is also contraindicated in patients with known or suspected hypersensitivity to any of its components.

Cilostazol should be used with caution in patients with any degree of heart failure. There is no information with respect to the efficacy or safety of the concurrent use of Cilostazol and Clopidogrel.

Pharmacokinetic studies have demonstrated that Omeprazole and Erythromycin significantly increased the systemic exposure of Cilostazol and/or its major metabolites. Population pharmacokinetic studies showed higher concentrations of Cilostazol among patients concurrently treated with Diltiazem.

There are no adequate and well controlled studies in pregnant women. Transfer of Cilostazol into milk has been reported in experimental animals. Because of the potential risk to nursing infants, a decision should be made to discontinue nursing or to discontinue Cilostazol.

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

Penicillinase-resistant penicillins

Flucloxacillin is active against Gram-positive organisms including penicillinase producing strains. It has little activity against Gram-negative bacilli. Flucloxacillin acts by inhibiting the formation of cell wall of bacteria. Flucloxacillin is isoxazolyl penicillin which combined the properties of resistance to hydrolysis by penicillinase, gastric acid stability and activity against gram-positive bacteria. Flucloxacillin is a bactericidal antibiotic that is particularly useful against penicillinase-producing staphylococci. Flucloxacillin kills bacterial cellwall, thus interfering with peptidoglycan synthesis. Peptidoglycan is a heteropolymeric structure that provides the cell wall with its mechanical stability. The final stage of peptidoglycan synthesis involves the completion of the cross-linking with the terminal glycine residue of the pentaglycin bridge linking to the fourth residue of the pentapeptide (D-alanine). The transpeptidase enzyme that performs this step is inhibited by Flucloxacillin. As a result the bacterial cellwall is weakened, the cell swells and then ruptures. Flucloxacillin resists the action of bacterial penicillinase probably because of the steric hindrance induced by the acyl side chain which prevents the opening of the β- lactam ring.

Oral administration:

• Adult: 250 mg four times daily. Dosage may be doubled in severe infections. In osteomyelitis and endocarditis, up to 8 gm daily is used in 6-8 hourly divided doses.
• Children (2-10 years): 1/2 of adult dose.
• Children (Under 2 years): 1/4 of adult dose.

Parenteral administration:
Adult or Elderly:

• Intramuscular Injection: 250 mg four times daily.
• Intravenous Injection: 250 mg-1 g four times daily by slow injection over 3 to 4 minutes or by intravenous infusion.
• All systemic doses may be doubled in severe infections: doses up to 8 g daily have been suggested for endocarditis or osteomyelitis.

Children:

• 2-10 years: half of the adult dose.
• Under 2 years: a quarter of the adult dose.

Oral doses should be administered 1 hour before meal.

There have been some common side effects of gastrointestinal tract such as nausea, vomiting, diarrhoea, dyspepsia and other minor gastrointestinal disturbances. Besides these rashes, urticaria, purpura, fever, interstitial nephritis, hepatitis and cholestatic jaundice have been reported.

Flucloxacillin is contraindicated in penicillin hypersensitive patients.

Flucloxacillin should be used with caution in patients with evidence of hepatic dysfunction. Caution should also be exercised in the treatment of patients with an allergic diathesis.

Concurrent use of Flucloxacillin and may result in increased level of Flucloxacillin in blood for prolonged period.

US FDA Pregnancy Category of Flucloxacillin is B. There are, 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. Flucloxacillin have been shown to be excreted in human milk. So, caution should be exercised when Flucloxacillin is administered to a lactating mother.

In severe renal failure (creatinine clearance <10 ml/min), a reduction in dose or an extension of dose interval should be considered.

Flucloxacillin has been used in other routes in conjunction with systemic therapy. It has been administered in a dose of 250 mg to 500 mg daily by intraarticular injection, dissolved if necessary in a 0.5% solution of lignocaine hydrochloride, and by intrapleural injection in a dose of 250 mg daily. Using powder for injection, 125 mg-250 mg has been dissolved in 3 ml of sterile water and inhaled by nebuliser four times daily.

Penicillinase-resistant penicillins

Flucloxacillin is active against Gram-positive organisms including penicillinase producing strains. It has little activity against Gram-negative bacilli. Flucloxacillin acts by inhibiting the formation of cell wall of bacteria. Flucloxacillin is isoxazolyl penicillin which combined the properties of resistance to hydrolysis by penicillinase, gastric acid stability and activity against gram-positive bacteria. Flucloxacillin is a bactericidal antibiotic that is particularly useful against penicillinase-producing staphylococci. Flucloxacillin kills bacterial cellwall, thus interfering with peptidoglycan synthesis. Peptidoglycan is a heteropolymeric structure that provides the cell wall with its mechanical stability. The final stage of peptidoglycan synthesis involves the completion of the cross-linking with the terminal glycine residue of the pentaglycin bridge linking to the fourth residue of the pentapeptide (D-alanine). The transpeptidase enzyme that performs this step is inhibited by Flucloxacillin. As a result the bacterial cellwall is weakened, the cell swells and then ruptures. Flucloxacillin resists the action of bacterial penicillinase probably because of the steric hindrance induced by the acyl side chain which prevents the opening of the β- lactam ring.

Oral administration:

• Adult: 250 mg four times daily. Dosage may be doubled in severe infections. In osteomyelitis and endocarditis, up to 8 gm daily is used in 6-8 hourly divided doses.
• Children (2-10 years): 1/2 of adult dose.
• Children (Under 2 years): 1/4 of adult dose.

Parenteral administration:
Adult or Elderly:

• Intramuscular Injection: 250 mg four times daily.
• Intravenous Injection: 250 mg-1 g four times daily by slow injection over 3 to 4 minutes or by intravenous infusion.
• All systemic doses may be doubled in severe infections: doses up to 8 g daily have been suggested for endocarditis or osteomyelitis.

Children:

• 2-10 years: half of the adult dose.
• Under 2 years: a quarter of the adult dose.

Oral doses should be administered 1 hour before meal.

There have been some common side effects of gastrointestinal tract such as nausea, vomiting, diarrhoea, dyspepsia and other minor gastrointestinal disturbances. Besides these rashes, urticaria, purpura, fever, interstitial nephritis, hepatitis and cholestatic jaundice have been reported.

Flucloxacillin is contraindicated in penicillin hypersensitive patients.

Flucloxacillin should be used with caution in patients with evidence of hepatic dysfunction. Caution should also be exercised in the treatment of patients with an allergic diathesis.

Concurrent use of Flucloxacillin and may result in increased level of Flucloxacillin in blood for prolonged period.

US FDA Pregnancy Category of Flucloxacillin is B. There are, 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. Flucloxacillin have been shown to be excreted in human milk. So, caution should be exercised when Flucloxacillin is administered to a lactating mother.

In severe renal failure (creatinine clearance <10 ml/min), a reduction in dose or an extension of dose interval should be considered.

Flucloxacillin has been used in other routes in conjunction with systemic therapy. It has been administered in a dose of 250 mg to 500 mg daily by intraarticular injection, dissolved if necessary in a 0.5% solution of lignocaine hydrochloride, and by intrapleural injection in a dose of 250 mg daily. Using powder for injection, 125 mg-250 mg has been dissolved in 3 ml of sterile water and inhaled by nebuliser four times daily.

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

Indapamide is indicated in the treatment of essential hypertension . It is effective in treating hypertension in patients with renal function impairment, although its diuretic effect is reduced. Indapamide is also indicated for the treatment of salt and fluid retention associated with congestive heart failure.

Thiazide diuretics & related drugs

Indapamide is a diuretic antihypertensive. It appears to cause vasodilation, probably by inhibiting the passage of calcium and other ions (sodium, potassium) across membranes. It has an extra-renal antihypertensive action resulting in a decrease in vascular hyperreactivity and a reduction in total peripheral and arteriolar resistance.

One tablet daily preferably in the morning. In more sever case Indapamide can be combine with other categories of anti-hypertensive agent. The safety and effectiveness in pediatric patients have not been established

Side effects of Indapamide include headache, anorexia, gastric irritation,nausea, vomiting, constipation, diarrhoea etc.

This drug must not be taken in the following conditions:

• Hypersensitivity to sulfonamides
• Severe renal failure
• Hepatic encephalopathy or severe hepatic failure
• Hypokalaemia

Monitoring of potassium and uric acid serum levels is recommended, especially in subjects with a predisposition or sensitivity to hypokalemia and in patients with gout. Although no allergic manifestations have been reported during clinical trials, patients with a history of allergy to sulfonamide derivatives should be closely monitored.

Other antihypertensive: Indapamide may add to or potentiate the action of other antihypertensive drugs.

Norepinephrine: Indapamide like thiazides, may decrease arterial responsiveness to norepinephrine.

Lithium: In general, diuretics should not be given concomitantly with lithium because they reduce its renal clearance and add a high risk of lithium toxicity.

There are no adequate and well-controlled studies in pregnant women and so Indapamide is not recommended. Mothers taking Indapamide should not breast feed.

Symptoms: These could include: allergies, skin rashes, epigastric pain, nausea, photosensitivity, dizziness, weakness and paraesthesia.

Treatment: Treatment is supportive and symptomatic, directed at correcting the electrolyte abnormalities.

Store in a cool and dry place. Protect from light and moisture.

Dipeptidyl Peptidase-4 (DPP-4) inhibitor

Sitagliptin is a DPP-4 inhibitor, which is believed to exert its actions in patients with type 2 diabetes by slowing the inactivation of incretin hormones. Concentrations of the active intact hormones are increased by Sitagliptin, thereby increasing and prolonging the action of these hormones. Incretin hormones, including glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), are released by the intestine throughout the day, and levels are increased in response to a meal. These hormones are rapidly inactivated by the enzyme, DPP-4. The incretins are part of an endogenous system involved in the physiologic regulation of glucose homeostasis. When blood glucose concentrations are normal or elevated, GLP-1 and GIP increase insulin synthesis and release from pancreatic beta cells by intracellular signaling pathways involving cyclic AMP. GLP-1 also lowers glucagon secretion from pancreatic alpha cells, leading to reduced hepatic glucose production. By increasing and prolonging active incretin levels, Sitagliptin increases insulin release and decreases glucagon levels in the circulation in a glucose-dependent manner. Sitagliptin demonstrates selectivity for DPP-4 and does not inhibit DPP-8 or DPP-9 activity in vitro at concentrations approximating those from therapeutic doses.

The recommended dose of sitagliptin is 50 mg twice a day and 100 mg once daily. Sitagliptin can be taken with or without food.

The most common adverse reactions include headache, upper respiratory tract infection and nasopharyngitis. Hypoglycemia may occur in patients treated with the combination to Sitagliptin and sulfonylurea and add on to insulin.

History of a serious hypersensitivity reaction to sitagliptin, such as anaphylaxis or angioedema.

If pancreatitis is suspected, sitagliptin should promptly be discontinued and appropriate management should be initiated.

Use in Patients with Renal Insufficiency: Dosage adjustment is recommended in patients with moderate or severe renal insufficiency and in patients with ESRD requiring hemodialysis or peritoneal dialysis.

Use with medications known to cause Hypoglycemia: When sitagliptin is used in combination therapy dosage adjustment of sulfonylurea or insulin may be required to reduce the risk of hypoglycemia.

Hypersensitivity Reactions: There have been post-marketing reports of serious hypersensitivity reactions in patients treated with sitagliptin. These reactions include anaphylaxis, angioedema, and exfoliative skin conditions including Stevens-Johnson syndrome. If a hypersensitivity reaction is suspected, discontinue sitagliptin, assess for other potential causes for the event, and institute alternative treatment for diabetes.

Effects of sitagliptin on other Drugs: Sitagliptin did not meaningfully alter the pharmacokinetics of metformin, glyburide, simvastatin, rosiglitazone, warfarin, or oral contraceptive.

Digoxin: Sitagliptin slightly increases the mean of Digoxin concentration. However, no dose adjustment of either drug is required.

Pregnancy Category B. Reproduction studies have been performed in rats and rabbits. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Sitagliptin is secreted in the milk of lactating rats at milk to plasma ratio of 4:1. It is not known whether sitagliptin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when sitagliptin is administered to a nursing woman.

Pediatric Use: Safety and effectiveness of sitagliptin in pediatric patients under 18 years of age have not been established.

Geriatric Use: This drug is known to be substantially excreted by the kidney. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection in the elderly, and it may be useful to assess renal function in these patients prior to initiating dosing and periodically thereafter.

For patients with mild renal insufciency: (CrCl <50 ml/min or serum creatinine levels of <1.7 mg/DL in men and <1.5 mg/DL in women), no dosage adjustment for sitagliptin is required.

For patients with moderate renal insufciency: (CrCl <30 to <50 mL/min, or serum creatinine levels of >1.7 to <3.0 mg/dL in men and >1.5 to <2.5 mg/dL in women), the dose of sitagliptin is 50 mg once daily.

For patients with severe renal insufficiency: (CrCl <30 mL/min or serum creatinine levels of >3.0 mg/dL in men and 2.5 mg/dL in women) or with end-stage renal disease (ESRD) requiring hemodialysis or peritoneal dialysis, the dose of sitagliptin is 25 mg once daily. Sitagliptin may be administered without regard to the limiting of hemodialysis.

During controlled clinical trials in healthy subjects, single doses of up to 800 mg Sitagliptin were administered. Maximal mean increases in QTc of 8.0 msec were observed in one study at a dose of 800 mg Sitagliptin, a mean effect that is not considered clinically important. There is no experience with doses above 800 mg in clinical studies. In Phase I multiple-dose studies, there were no dose-related clinical adverse reactions observed with Sitagliptin with doses of up to 600 mg per day for periods of up to 10 days and 400 mg per day for up to 28 days.

In the event of an overdose, it is reasonable to employ the usual supportive measures, e.g., remove unabsorbed material from the gastrointestinal tract, employ clinical monitoring (including obtaining an electrocardiogram), and institute supportive therapy as dictated by the patient's clinical status. Sitagliptin is modestly dialyzable. In clinical studies, approximately 13.5% of the dose was removed over a 3- to 4-hour hemodialysis session. Prolonged hemodialysis may be considered if clinically appropriate. It is not known if sitagliptin is dialyzable by peritoneal dialysis.

Store below 25°C in a dry place away from light. Keep the medicines in a safe place, out of the reach of children. Do not use later than the date of expiry. To be dispensed only on the prescription of a registered physician

Combination Oral hypoglycemic preparations

This tablet combines two antihyperglycemic agents with complementary mechanisms of action to improve glycemic control in patients with type 2 diabetes. Sitagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor, and Metformin HCl, a member of the biguanide class. Sitagliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor, which is believed to exert its actions in patients with type 2 diabetes by slowing the inactivation of incretin hormones. Incretin hormones, including glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), are released by the intestine throughout the day, and levels are increased in response to a meal. These hormones are rapidly inactivated by the enzyme, DPP-4. The incretins are part of an endogenous system involved in the physiologic regulation of glucose homeostasis. When blood glucose concentrations are normal or elevated then GLP-1 and GIP increase insulin synthesis and release from pancreatic beta cells by intracellular signaling pathways involving cyclic AMP. GLP-1 also lowers glucagon secretion from pancreatic alpha cells, leading to reduced hepatic glucose production. By increasing and prolonging active incretin levels, Sitagliptin increases insulin release and decreases glucagon levels in the circulation in a glucose-dependent manner. The pharmacologic mechanism of action of Metformin HCl is different from other classes of oral antihyperglycemic agents. Metformin HCl decreases hepatic glucose production, decreases intestinal absorption of glucose and increases peripheral glucose uptake and utilization.

Dose of film-coated tablet: The dosage of this tablet should be individualized on the basis of the patient's current regimen, efectiveness, and tolerability while not exceeding the maximum recommended daily dose of 100 mg sitagliptin and 2000 mg metformin. Initial combination therapy or maintenance of combination therapy should be individualized and left to the discretion of the health care provider.

This tablet should generally be given twice daily with meals, with gradual dose escalation, to reduce the gastrointestinal (GI) side efects due to metformin.

The starting dose of this tablet should be based on the patient’s current regimen. This tablet should be given twice daily with meals.

The recommended starting dose in patients not currently treated with metformin is 50 mg sitagliptin/500 mg metformin hydrochloride twice daily, with gradual dose escalation recommended to reduce gastrointestinal side efects associated with metformin.

The starting dose in patients already treated with metformin should provide sitagliptin dosed as 50 mg twice daily (100 mg total daily dose) and the dose of metformin already being taken. For patients taking metformin 850 mg twice daily, the recommended starting dose of this tablet is 50 mg sitagliptin/1000 mg metformin hydrochloride twice daily.

No studies have been performed specifcally examining the safety and efcacy of Sitagliptin Phosphate Monohydrate INN/Metformin Hydrochloride BP in patients previously treated with other oral antihyperglycemic agents and switched to Sitagliptin Phosphate Monohydrate INN/Metformin Hydrochloride BP. Any change in therapy of type 2 diabetes should be undertaken with care and appropriate monitoring as changes in glycemic control can occur.

Dose of extended-release tablet: Administer once daily with a meal preferably in the evening. Gradually escalate the dose to reduce the gastrointestinal side effects due to Metformin. May adjust the dosing based on effectiveness and tolerability while not exceeding the maximum recommended daily dose of 100 mg Sitagliptin and 2000 mg Metformin extended-release. Maintain the same total daily dose of Sitagliptin and Metformin when changing between film-coated tablet and extended-release tablet, without exceeding the maximum recommended daily dose of 2000 mg Metformin extended-release.

Patients using two extended-release tablets (such as two 50/500 or two 50/1000 tablets) should take the two tablets together once daily. The 100 mg Sitagliptin/1000 mg Metformin HCI extended-release tablet should be taken as a single tablet once daily.

Patients treated with an insulin secretagogue or insulin: Co-administration of the combination with an insulin secretagogue (e.g., sulfonylurea) or insulin may require lower doses of the insulin secretagogue or insulin to reduce the risk of hypoglycemia.

The most common adverse reactions reported in ≥5% of patients simultaneously started on sitagliptin and metformin and more commonly than in patients treated with placebo were diarrhea, upper respiratory tract infection, and headache.

Adverse reactions reported in ≥5% of patients treated with sitagliptin in combination with sulfonylurea and metformin and more commonly than in patients treated with placebo in combination with sulfonylurea and metformin were hypoglycemia and headache.

Hypoglycemia was the only adverse reaction reported in ≥5% of patients treated with sitagliptin in combination with insulin and metformin and more commonly than in patients treated with placebo in combination with insulin and metformin.

Nasopharyngitis was the only adverse reaction reported in ≥5% of patients treated with sitagliptin monotherapy and more commonly than in patients given placebo.

The most common (>5%) adverse reactions due to initiation of metformin therapy are diarrhea, nausea/vomiting, fatulence, abdominal discomfort, indigestion, asthenia, and headache.

This tablet is contraindicated in patients with:

• Renal disease or renal dysfunction, e.g., as suggested by serum creatinine levels ≥1.5 mg/dL [males], ≥1.4 mg/dL [females] or abnormal creatinine clearance which may also result from conditions such as cardiovascular collapse (shock), acute myocardial infarction, and septicemia
• Acute or chronic metabolic acidosis, including diabetic ketoacidosis, with or without coma.
• History of a serious hypersensitivity reaction to this tablet or sitagliptin, such as anaphylaxis or angioedema.

This tablet should be temporarily discontinued in patients undergoing radiologic studies involving intravascular administration of iodinated contrast materials, because use of such products may result in acute alteration of renal function.

Lactic Acidosis-

• Lactic acidosis can occur due to metformin accumulation. The risk increases with conditions such as sepsis, dehydration, excess alcohol intake, hepatic insufciency, renal impairment, and acute congestive heart failure.
• Symptoms include malaise, myalgias, respiratory distress, increasing somnolence, and nonspecifc abdominal distress. Laboratory abnormalities include low pH, increased anion gap and elevated blood lactate.
• If acidosis is suspected, discontinue this tablet and hospitalize the patient immediately.
• Regular monitoring of thyroid-stimulating hormone (TSH) levels is recommended in patients with hypothyroidism.
• Long-term treatment with metformin has been associated with a decrease in vitamin B12 serum levels which may cause peripheral neuropathy. Monitoring of the vitamin B12 level is recommended.

Others-

• Do not use this tablet in patients with hepatic disease.
• There have been postmarketing reports of acute renal failure, sometimes requiring dialysis. Before initiating this tablet and at least annually thereafter, assess renal function and verify as normal.
• There have been postmarketing reports of acute pancreatitis, including fatal and non-fatal hemorrhagic or necrotizing pancreatitis. If pancreatitis is suspected, promptly discontinue this tablet.
• Measure hematologic parameters annually.
• Warn patients against excessive alcohol intake.
• May need to discontinue this tablet and temporarily use insulin during periods of stress and decreased intake of fluids and food as may occur with fever, trauma, infection or surgery.
• Promptly evaluate patients previously controlled on this tablet who develop laboratory abnormalities or clinical illness for evidence of ketoacidosis or lactic acidosis.
• When used with an insulin secretagogue (e.g., sulfonylurea) or with insulin, a lower dose of the insulin secretagogue or insulin may be required to reduce the risk of hypoglycemia.
• There have been postmarketing reports of serious allergic and hypersensitivity reactions in patients treated with sitagliptin (one of the components of this tablet ), such as anaphylaxis, angioedema, and exfoliative skin conditions including Stevens-Johnson syndrome. In such cases, promptly stop this tablet, assess for other potential causes, and institute appropriate monitoring and treatment, and initiate alternative treatment for diabetes.
• There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with Sitagliptin Phosphate Monohydrate INN/Metformin Hydrochloride BP or any other anti-diabetic drug.

Cationic Drugs: Cationic drugs eliminated by renal tubular secretion: Use with caution.

Phenprocoumon: Metformin may decrease the anticoagulant effect of phenprocoumon. Therefore, close monitoring of the INR is recommended.

Levothyroxine: Levothyroxine can reduce the hypoglycemic effect of metformin. Monitoring of blood glucose levels is recommended, especially when thyroid hormone therapy is initiated or stopped, and the dosage of metformin must be adjusted if necessary.

Pregnancy Category B. There are no adequate and well-controlled studies in pregnant women with Sitagliptin Phosphate Monohydrate INN/Metformin Hydrochloride BP or its individual components; therefore, the safety of Sitagliptin Phosphate Monohydrate INN/Metformin Hydrochloride BP in pregnant women is not known. This tablet should be used during pregnancy only if clearly needed.

It is not known whether sitagliptin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when this tablet is administered to a nursing woman.

Sitagliptin: In the event of an overdose, it is reasonable to employ the usual supportive measures, e.g., remove unabsorbed material from the gastrointestinal tract, employ clinical monitoring (including obtaining an electrocardiogram), and institute supportive therapy as indicated by the patient's clinical status. Sitagliptin is modestly dialyzable. Prolonged hemodialysis may be considered if clinically appropriate. It is not known if sitagliptin is dialyzable by peritoneal dialysis.

Metformin hydrochloride: Overdose of metformin hydrochloride has occurred, including ingestion of amounts greater than 50 grams. Metformin is dialyzable with a clearance of up to 170 mL/min under good hemodynamic conditions. Therefore, hemodialysis may be useful for removal of accumulated drug from patients in whom metformin overdosage is suspected. Pancreatitis may occur in the context of a metformin overdose.

Store below 25°C in a dry place away from light. Keep the medicines in a safe place, out of the reach of children. Do not use later than the date of expiry. To be dispensed only on the prescription of a registered physician.

• There have been postmarketing reports of acute renal failure, sometimes requiring dialysis. Before initiating this tablet and at least annually thereafter, assess renal function and verify as normal.
• There have been postmarketing reports of acute pancreatitis, including fatal and non-fatal hemorrhagic or necrotizing pancreatitis. If pancreatitis is suspected, promptly discontinue this tablet.
• Measure hematologic parameters annually.
• Warn patients against excessive alcohol intake.
• May need to discontinue this tablet and temporarily use insulin during periods of stress and decreased intake of fluids and food as may occur with fever, trauma, infection or surgery.
• Promptly evaluate patients previously controlled on this tablet who develop laboratory abnormalities or clinical illness for evidence of ketoacidosis or lactic acidosis.
• When used with an insulin secretagogue (e.g., sulfonylurea) or with insulin, a lower dose of the insulin secretagogue or insulin may be required to reduce the risk of hypoglycemia.
• There have been postmarketing reports of serious allergic and hypersensitivity reactions in patients treated with sitagliptin (one of the components of this tablet ), such as anaphylaxis, angioedema, and exfoliative skin conditions including Stevens-Johnson syndrome. In such cases, promptly stop this tablet, assess for other potential causes, and institute appropriate monitoring and treatment, and initiate alternative treatment for diabetes.
• There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with Sitagliptin Phosphate Monohydrate INN/Metformin Hydrochloride BP or any other anti-diabetic drug.

Cationic Drugs: Cationic drugs eliminated by renal tubular secretion: Use with caution.

Phenprocoumon: Metformin may decrease the anticoagulant effect of phenprocoumon. Therefore, close monitoring of the INR is recommended.

Levothyroxine: Levothyroxine can reduce the hypoglycemic effect of metformin. Monitoring of blood glucose levels is recommended, especially when thyroid hormone therapy is initiated or stopped, and the dosage of metformin must be adjusted if necessary.

Pregnancy Category B. There are no adequate and well-controlled studies in pregnant women with Sitagliptin Phosphate Monohydrate INN/Metformin Hydrochloride BP or its individual components; therefore, the safety of Sitagliptin Phosphate Monohydrate INN/Metformin Hydrochloride BP in pregnant women is not known. This tablet should be used during pregnancy only if clearly needed.

It is not known whether sitagliptin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when this tablet is administered to a nursing woman.

Sitagliptin: In the event of an overdose, it is reasonable to employ the usual supportive measures, e.g., remove unabsorbed material from the gastrointestinal tract, employ clinical monitoring (including obtaining an electrocardiogram), and institute supportive therapy as indicated by the patient's clinical status. Sitagliptin is modestly dialyzable. Prolonged hemodialysis may be considered if clinically appropriate. It is not known if sitagliptin is dialyzable by peritoneal dialysis.

Metformin hydrochloride: Overdose of metformin hydrochloride has occurred, including ingestion of amounts greater than 50 grams. Metformin is dialyzable with a clearance of up to 170 mL/min under good hemodynamic conditions. Therefore, hemodialysis may be useful for removal of accumulated drug from patients in whom metformin overdosage is suspected. Pancreatitis may occur in the context of a metformin overdose.

Store below 25°C in a dry place away from light. Keep the medicines in a safe place, out of the reach of children. Do not use later than the date of expiry. To be dispensed only on the prescription of a registered physician.

This tablet is indicated as an adjunct to diet and exercises to improve glycaemic control in patients with type 2 diabetes mellitus whose diabetes is not adequately controlled on Metformin Hydrochloride or Vildagliptin alone or who are already treated with the combination of Vildagliptin and Metformin Hydrochloride, as separate tablets.

Combination Oral hypoglycemic preparations

Vildagliptin acts primarily by inhibiting DPP-4 (Dipeptidyl peptidase-4), the enzyme responsible for the degradation of the incretin hormones GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide). The administration of Vildagliptin results in a rapid and complete inhibition of DPP-4 activity resulting in increased fasting and postprandial endogenous levels of the incretin hormones GLP-1 and GIP. By increasing the endogenous levels of these incretin hormones, Vildagliptin increases insulin secretion from the pancreatic beta cell and decreases glucagon secretion from alpha cell. The enhanced increase in the insulin/glucagon ratio during hyperglycaemia due to increased incretin hormone levels results in a decrease in fasting and postprandial hepatic glucose production, leading to reduced glycaemia.

Metformin Hydrochloride is a biguanide type oral antihyperglycemic drug used in the management of type 2 diabetes. It lowers both basal and postprandial plasma glucose. Its mechanism of action is different from those of sulfonylureas and it does not produce hypoglycemia. Glucomin decreases hepatic glucose production, decreases intestinal absorption of glucose and improves insulin sensitivity by an increase in peripheral glucose uptake and utilization.

Adults: Based on the patient's current dose of Metformin, this combination may be initiated at twice daily, 1 tablet in the morning and the other in the evening. Patients receiving Vildagliptin and Metformin from separate tablets may be switched to this combination containing the same doses of each component. Doses higher than 100 mg of vildagliptin are not recommended. There is no clinical experience of Vildagliptin and Metformin in triple combination with other antidiabetic agents. Taking this combination with or just after food may reduce gastrointestinal symptoms associated with Metformin.

The most common side effects are headache, tremor, dizziness, nausea, hypoglycaemia etc.

This combination is contraindicated in patients with known hypersensitivity to Vildagliptin or Metformin Hydrochloride or to any of the excipients. It is contraindicated in patients with renal disease or renal dysfunction, acute myocardial infarction, and septicaemia. It is also contraindicated in patients with congestive heart failure patients and in patients with acute or chronic metabolic acidosis, including diabetic ketoacidosis, with or without coma. It should be temporarily discontinued in patients undergoing radiologic studies involving intravascular administration of iodinated contrast materials, because use of such products may result in acute alteration of renal function.

Lactic acidosis can occur due to Metformin accumulation. If metabolic acidosis is suspected, treatment should be discontinued and the patient should be hospitalized immediately. Serum creatinine should be monitored at least once a year in patients with normal renal function and 2–4 times a year in patients with serum creatinine levels at the upper limit of normal and in elderly patients. Special caution should be exercised in elderly patients where renal function may become impaired (e.g. when initiating antihypertensives, diuretics or NSAIDs). It is recommended that Liver Function Tests (LFTs) are monitored prior to initiation of this drug, at three-monthly intervals in the first year and periodically thereafter. If transaminase levels are increased, patients should be monitored with a second liver function evaluation to confirm the finding and be followed thereafter with frequent liver function tests until the abnormality return to normal. If AST or ALT persist at 3 x ULN, Vildagliptin & Metformin tablets should be stopped Patients who develop jaundice or other signs of liver dysfunction. Following withdrawal of treatment with Vildagliptin & Metformin and LFT normalization, treatment with Vildagliptin & Metformin should not be reinitiated. Vildagliptin & Metformin tablets should be discontinued 48 hours before elective surgery with general anaesthesia and should not usually be resumed earlier than 48 hours afterwards.

No clinically relevant pharmacokinetic interaction was observed when Vildagliptin (100 mg once daily) was co-administered with Metformin Hydrochloride (1,000 mg once daily). Vildagliptin has a low potential for drug interactions. Since Vildagliptin is not a cytochrome P (CYP) 450 enzyme substrate nor does it inhibit nor induces CYP 450 enzymes, it is not likely to interact with co-medications that are substrates, inhibitors or inducers of these enzymes. As a result of these studies no clinically relevant interactions with other oral antidiabetics (glibenclamide, pioglitazone, metformin hydrochloride), amlodipine, digoxin, ramipril, simvastatin, valsartan or warfarin were observed after co-administration with vildagliptin. On the other hand, furosemide, nifedipine and glyburide increase Cmax and blood AUC of Metformin with no change in renal clearance of Metformin.

There are no adequate and well controlled studies in pregnant women and therefore, this combination should not be used during pregnancy unless the potential benefit justifies the potential risk to the foetus. No studies have been conducted with the components of this combination. As it is not known whether Vildagliptin and/or Metformin Hydrochloride is excreted in human milk this combination should not be administered to breast-feeding women.

Use in pediatric patients: The safety and effectiveness of this combination in pediatric patients have not been established. Therefore, this combination is not recommended for use in children below 18 years of age.

Use in geriatric patients: As Metformin is excreted via the kidney, and elderly patients have a tendency to decreased renal function, elderly patients taking this combination should have their renal function monitored regularly. This combination should only be used in elderly patients with normal renal function.

Patients with renal impairment: This combination should not be used in patients with renal failure or renal dysfunction, e.g. serum creatinine levels > 1.5 mg/dl (>135 micro mol/L) in males and > 1.4 mg/dl (>110 micro mol/L) in females.

Patients with hepatic impairment: This combination is not recommended in patients with hepatic impairment including patients with a pre-treatment ALT or AST >3 X the upper limit of normal.

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

Indapamide is indicated in the treatment of essential hypertension . It is effective in treating hypertension in patients with renal function impairment, although its diuretic effect is reduced. Indapamide is also indicated for the treatment of salt and fluid retention associated with congestive heart failure.

Thiazide diuretics & related drugs

Indapamide is a diuretic antihypertensive. It appears to cause vasodilation, probably by inhibiting the passage of calcium and other ions (sodium, potassium) across membranes. It has an extra-renal antihypertensive action resulting in a decrease in vascular hyperreactivity and a reduction in total peripheral and arteriolar resistance.

One tablet daily preferably in the morning. In more sever case Indapamide can be combine with other categories of anti-hypertensive agent. The safety and effectiveness in pediatric patients have not been established

Side effects of Indapamide include headache, anorexia, gastric irritation,nausea, vomiting, constipation, diarrhoea etc.

This drug must not be taken in the following conditions:

• Hypersensitivity to sulfonamides
• Severe renal failure
• Hepatic encephalopathy or severe hepatic failure
• Hypokalaemia

Monitoring of potassium and uric acid serum levels is recommended, especially in subjects with a predisposition or sensitivity to hypokalemia and in patients with gout. Although no allergic manifestations have been reported during clinical trials, patients with a history of allergy to sulfonamide derivatives should be closely monitored.

Other antihypertensive: Indapamide may add to or potentiate the action of other antihypertensive drugs.

Norepinephrine: Indapamide like thiazides, may decrease arterial responsiveness to norepinephrine.

Lithium: In general, diuretics should not be given concomitantly with lithium because they reduce its renal clearance and add a high risk of lithium toxicity.

There are no adequate and well-controlled studies in pregnant women and so Indapamide is not recommended. Mothers taking Indapamide should not breast feed.

Symptoms: These could include: allergies, skin rashes, epigastric pain, nausea, photosensitivity, dizziness, weakness and paraesthesia.

Treatment: Treatment is supportive and symptomatic, directed at correcting the electrolyte abnormalities.

Store in a cool and dry place. Protect from light and moisture.

Indapamide & Perindopril combination is indicated in essential hypertension.

Combined antihypertensive preparations

Perindopril is an ACE inhibitor, which acts by inhibiting the conversion of angiotensin I to angiotensin II, reducing the activity of the sympathetic nervous system and inhibiting enzyme kininase, which is involved in the conversion of bradykinin and other substances.

Indapamide is a sulfonamide derivative with an indole ring. It inhibits the reabsorption of sodium in the cortical dilution segment, thus increasing urinary output, resulting in an antihypertensive effect.

2 mg perindopril / 0.625 mg indapamide is indicated for the initial treatment of mild to moderate essential hypertension.

4 mg perindopril / 1.25 mg indapamide and 8 mg perindopril / 2.5 mg indapamide) are indicated in the treatment of mild to moderate essential hypertension in patients for whom combination therapy is appropriate.

4 mg perindopril / 1.25 mg indapamide and 8 mg perindopril / 2.5 mg indapamide are not indicated for initial therapy. Patients in whom perindopril and indapamide are initiated simultaneously can develop symptomatic hypotension.

Patients should be titrated on the individual drugs. If the fixed combination represents the dosage determined by this titration, the use of (4 mg perindopril / 1.25 mg indapamide) and (8 mg perindopril / 2.5 mg indapamide) may prove to be more convenient in the management of patients. If during maintenance therapy dosage adjustment is necessary, it is advisable to use individual drugs

The safety and efficacy of perindopril / indapamide in renovascular hypertension and in congestive heart failure have not been established and therefore, their use in this condition is not recommended.

Geriatrics (> 65 years of age): Although the blood pressure response and safety profile of in patients >65 years old were comparable to those of the younger adult patients, greater sensitivity of some elderly patients cannot be ruled out.

Pediatrics: The safety and effectiveness of in children have not been established. Its use in this age group, therefore, is not recommended.

Asthenia, dizziness, headache, mood swings and/or sleep disturbances, cramps, hypotension, allergic reactions, skin rashes, gastrointestinal disorders, dry cough, dry mouth, risk of dehydration in the elderly and in patients suffering from heart failure; changes in blood test results may occur.

Absolute: Known allergy to perindopril Erbumine, indapamide, or sulfonamides; history of Quincke's edema linked to previous ACE inhibitor therapy; severe renal failure; serious liver disorder; hypokalemia; pregnancy; lactation. 

Relative: Combination therapy with lithium, potassium salts, potassium-sparing diuretics, and certain medicines which can cause heart rhythm disorders.

Disorders of electrolyte balance, diabetes, gout, hypotension, or strict sodium-free diets, heart or renal failure, atherosclerosis, renal artery stenosis, elderly.

Increased risk of lithium toxicity. May cause and potentiate orthostatic hypotension when used with alcohol, barbiturates, neuroleptics, narcotics or other antihypertensives. Increased risk of acute renal insufficiency in dehydrated patients when used with systemic NSAIDs or high dose salicylates. May increase risk of hypoglycaemia in patients on concurrent treatment with hypoglycaemic sulfonamides/insulin. Concurrent use with baclofen may potentiate antihypertensive effect. May reduce antihypertensive effect when used with corticosteroids or tetracosactide. Increased risk of hyperkalaemia when used with potassium-sparing diuretics or potassium supplements. May increase hypotensive effect of certain anaesthetic drugs. Increased risk of leucopenia when used with allopurinol, immunosuppressants, procainamide or systemic corticosteoids. Additive hypotensive effect when used with other antihypertensives.

There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.

Animal reproduction studies have failed to demonstrate a risk to the fetus and there are no adequate and well-controlled studies in pregnant women OR Animal studies have shown an adverse effect, but adequate and well-controlled studies in pregnant women have failed to demonstrate a risk to the fetus in any trimester.

Renal failure:

• Creatinine clearance (CrCl) >30 ml/min: No dosage modification. 
• Creatinine clearance (CrCl) <30 ml/min: Treatment contraindicated.

Symptoms include hypotension, nausea, vomiting, cramps, dizziness, sleepiness mental confusion, oliguria which may progress to anuria. Salt and water disturbances (low sodium levels, low potassium levels) may also occur. Gastric lavage or administration of activated charcoal may be used to remove the ingested drug. Monitor and maintain fluid and electrolyte balance.

Store below 30° C.
