Third generation Cephalosporins

Cefixime is a third generation semisynthetic cephalosporin antibiotic for oral administration. It is bactericidal against a broad spectrum of gram positive and gram negative bacteria at easily achievable plasma concentrations. It kills bacteria by interfering in the synthesis of bacterial cell wall. It is highly stable in the presence of Beta-lactamase enzyme. As a result, many organisms resistant to penicillins and some cephalsporins due to the presence of beta-lactamases, may be susceptible to Cefixime. Absorption of it is about 40% to 50% whether administered with or without food.

The usual course of treatment is 7 days. This may be continued for up to 14 days depending on the severity of the infection.

Adult and children over 12 years: The recommended adult dose is 200-400 mg (1 to 2 capsules) daily, given either as a single dose or in two divided doses. For the treatment of uncomplicated cervical/urethral gonococcal infections, a single oral dose of Cefixime 400 mg is recommended.

Children (6 month or older): Usually 8 mg/kg/day given as a single dose or in two divided doses or may be given as following

• ½-1 year: 75 mg daily.
• 1-4 years: 100 mg daily.
• 5-10 years: 200 mg daily.
• 11-12 years: 300 mg daily
• In typhoid fever, dosage should be 10 mg/kg/day for 14 days.

Children (under 6 month): The safety and efficacy of Cefixime has not been established in children aged less than 6 months.

The drug is generally well tolerated. The most frequent side effects are diarrhoea and stool changes; that have been more commonly associated with higher doses. Other side effects are nausea, abdominal pain, dyspepsia, vomiting, flatulence, headache and dizziness. Allergies in the form of rash, pruritus, urticaria, drug fever and arthralgia have been reported. These reactions usually subsided upon dicontinuation of therapy.

It is contraindicated in hypersensitivity to Cefixime or other cephalosporins.

The drug should be prescribed with caution in individuals with a history of gastrointestinal disease, particularly colitis. The drug should be given with caution in patients with marked impaired renal function as well as those undergoing continuous ambulatory peritoneal dialysis and hemodialysis. Dosage adjustment is only necessary in severe renal failure (creatinine clearance < 20 ml/min), in that case a dose of 200 mg once daily should not be exceeded.

Carbamazepine: Concomitant use elevates the carbamazepine level. Warfarin and other anticoagulants: Concomitant use increases prothrombin time.

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. It is not known that Cefixime is excreted in human milk. So, caution should be exercised when Cefixime is administered to a nursing woman.

Gastric Lavage may be indicated; otherwise, no specific antidote exists. Cefixime is not removed in significant quantities from the circulation by hemodialysis or peritoneal dialysis. Adverse reactions in small numbers of healthy adult volunteers receiving single doses up to 2 g of Cefixime did not differ from the profile seen in patients treated at the recommended doses.

Keep below 30ºC temperature, protected from light & moisture. Keep out of the reach of children.

Azithromycin is acid-stable and can therefore be taken orally with no need of protection from gastric acids. It is readily absorbed; its absorption is greater on an empty stomach. Time to peak concentration in adults is 2.1 to 3.2 hours for oral dosage forms. Due to the high concentration in phagocytes, azithromycin is actively transported to the site of infection. During active phagocytosis, large concentrations of azithromycin are released. The concentration of azithromycin in the tissues can be over 50 times higher than in plasma. This is due to ion trapping and the high lipid solubility.

Azithromycin's half-life allows a large single dose to be administered and yet maintain bacteriostatic levels in the infected tissue for several days. Following a single 500 mg dose, plasma concentrations of azithromycin declined in a polyphasic pattern with a mean apparent plasma clearance of 630 mL/min and a terminal elimination half life of 68 hours. The prolonged terminal half-life is thought to be due to extensive uptake and subsequent release of drug from tissues. Biliary excretion of azithromycin, predominantly unchanged, is a major route of elimination. Over the course of a week, approximately 6% of the administered dose appears as unchanged drug in urine.

Microbiology: Azithromycin acts by binding to the 50S ribosomal subunit of susceptible microorganisms and, thus, interfering with microbial protein synthesis. Nucleic acid synthesis is not affected. Azithromycin has been shown to be active against most isolates of the following microorganisms, both in vitro and in clinical infections:

• Aerobic and facultative gram-positive microorganisms: Staphylococcus aureus, Streptococcus agalactiae, Streptococcus pneumoniae, Streptococcus pyogenes
• Aerobic and facultative gram-negative microorganisms: Haemophilus ducreyi, Haemophilus influenzae, Moraxella catarrhalis, Neisseria gonorrhoeae
• Other microorganisms: Chlamydia pneumoniae, Chlamydia trachomatis , Mycoplasma pneumoniae , Betalactamase production should have no effect on azithromycin activity.
• Aerobic and facultative gram-positive microorganisms: Streptococci (Groups C,F,G), Viridans group streptococci
• Aerobic and facultative gram-negative microorganisms: Bordetella pertussis, Legionella pneumophila
• Anaerobic microorganisms: Peptostreptococcus species, Prevotella bivia

Oral-
Adult: 500 mg once daily orally for 3 days or 500 mg once on day 1, then 250 mg once on days 2-5 for 4 days. For sexually transmitted diseases caused by Chlamydia trachomatis in adults, the dose is 1 gm given as a single dose or 500 mg once on day 1, followed by 250 mg once daily for next 2 days may also be given.

Children:

• 10 mg/kg body weight once daily for 3 days for child over 6 months
• 200 mg (1 teaspoonful) for 3 days if body weight is 15-25 kg
• 300 mg (1½ teaspoonfuls) for 3 days if body weight is 26-35 kg; 400 mg (2 teaspoonfuls) for 3 days if body weight is 36-45 kg.
• In typhoid fever, 500 mg (2½ teaspoonfuls) once daily for 7-10 days is given.

Azithromycin Injection (For IV Infusion only): The recommended dose of Azithromycin for injection for the treatment of adult patients with community-acquired pneumonia due to the indicated organisms is:

• 500 mg as a single daily dose by the intravenous route for at least two days. Intravenous therapy should be followed by Azithromycin by the oral route at a single, daily dose of 500 mg, administered as two 250-mg tablets to complete a 7 to 10-day course of therapy. The timing of the switch to oral therapy should be done at the discretion of the physician and in accordance with clinical response.
• The recommended dose of Azithromycin for the treatment of adult patients with pelvic inflammatory disease due to the indicated organisms is: 500 mg as a single daily dose by the intravenous route for one or two days. Intravenous therapy should be followed by Azithromycin by the oral route at a single, daily dose of 250 mg to complete a 7-day course of therapy. The timing of the switch to oral therapy should be done at the discretion of the physician and in accordance with clinical response. If anaerobic microorganisms are suspected of contributing to the infection, an antimicrobial agent with anaerobic activity should be administered in combination with Azithromycin.
• Safety and effectiveness of azithromycin for injection in children or adolescents under 16 years have not been established.

Reconstitution procedure of suspension-

• Step 01: Shake the bottle well to loosen the powder.
• Step 02: Add boiled and cooled water up to the water mark of the bottle label.
• Step 03: Shake until powder is completely mixed with water.

Azithromycin should be taken at least 1 hour before or 2 hours after meal.

Azithromycin is well tolerated with a low incidence of side effects. The side effects include nausea, vomiting, abdominal discomfort (pain/cramps), flatulence, diarrhoea, headache, dizziness, and skin rashes and are reversible upon discontinuation of therapy.

Azithromycin is contraindicated in patients hypersensitive to Azithromycin or any other macrolide antibiotic. Co-administration of ergot derivatives and Azithromycin is contraindicated. Azithromycin is contraindicated in patients with hepatic diseases.

As with any antibiotic, observation for signs of superinfection with non-susceptible organisms, including fungi, is recommended. No dose adjustment is needed in patients with renal impairment.

Azithromycin absorption is reduced in presence of food and antacid. In patients receiving ergot alkaloids Azithromycin should be avoided because of the possibility of ergotism resulting from interaction of Azithromycin with the cytochrome P-450 system. As macrolides increase the plasma concentration of digoxin and cyclosporin, caution should be exercised while co-administration. There have been no drug interactions between Azithromycin and Warfarin, Theophylline, Carbamazepine, Methylprednisolone or Cimetidine.

Pregnancy Category of Azithromycin is B. Animal reproduction studies have demonstrated that Azithromycin has no evidence of harm to the fetus. There are no adequate and well controlled studies in pregnant women. Since animal reproduction studies are not always predictive of human response, Azithromycin should be used during pregnancy only if adequate alternatives are not available. It is not known whether Azithromycin is secreted in breast milk. So, caution should be exercised when Azithromycin is administered to nursing women.

There is no data on overdosage with Azithromycin. Typical symptoms of overdosage with macrolide antibiotics include hearing loss, severe nausea, vomiting and diarrhoea. Gastric lavage and general supportive measures are indicated.

H2 receptor antagonist

Ranitidine competitively blocks histamine at H2-receptors of the gastric parietal cells which inhibits gastric acid secretion. It does not affect pepsin secretion, pentagastrin-stimulated intrinsic factor secretion or serum gastrin.

Ranitidine Tablet & Syrup:

Duodenal and gastric ulcer: The usual dosage is 150 mg twice daily taken in the morning and evening or 300 mg as a single daily dose at night for 4 to 8 weeks.

Reflux oesophagitis: 150 mg twice daily or 300 mg at bed time for up to 8 weeks.

Zollinger Ellison syndrome: 150 mg 3 times daily and increased if necessary up to 6 g daily in divided doses. Dosage should be continued as long as clinically indicated.

Episodic dyspepsia: 150 mg twice daily or 300 mg at bed time for up to 6 weeks.

Maintenance: 150 mg at night for preventing recurrences.

Child (peptic ulcer): 2-4 mg/kg twice daily, maximum 300 mg daily.

Ranitidine IV injection & IV Infusion:

Ranitidine injection may be given either as a slow (over a period of at least two minutes) intravenous injection of 50 mg, after dilution to a volume of 20 ml per 50 mg dose, which may be repeated every six to eight hours; or as an intermittent intravenous infusion at a rate of 25 mg per hour for two hours; the infusion may be repeated at six to eight hour intervals; or as an intramuscular injection of 50 mg (2 ml) every six to eight hours. In the prophylaxis of haemorrhage from stress ulceration in seriously ill patients or the prophylaxis of recurrent haemorrhage in patients bleeding from peptic ulceration, parenteral administration may be continued until oral feeding commences.

In the prophylaxis of upper gastrointestinal haemorrhage from stress ulceration in seriously ill patient sapriming dose of 50 mg as low as intravenous injection followed by a continuous intravenous infusion of 0.125-0.250 mg/kg/hour may be preferred. In patients considered to be at risk of developing aspiration syndrome Ranitidine injection 50 mg may be given intramuscularly or by slow intravenous injection 45 to 60 minutes before induction of general anaesthesia.

Children: The recommended oral dose for the treatment of peptic ulcer in children is 2 mg/kg to 4 mg/kg twice daily to a maximum of 300 mg ranitidine per day. Safety and effectiveness of Ranitidine injection have not been established in case of children.

Ranitidine is well tolerated and side effects are usually uncommon. Altered bowel habit, dizziness, rash, tiredness, reversible confusional states, headache, decreased blood counts, muscle or joint pain have rarely been reported.

Patients hypersensitive to Ranitidine

Ranitidine should be given in reduced dosage to patients with impaired renal and hepatic function.

Delayed absorption and increased peak serum concentration with propantheline bromide. Ranitidine minimally inhibits hepatic metabolism of coumarin anticoagulants, theophylline, diazepam and propanolol. May alter absorption of pH-dependent drugs (e.g. ketoconazole, midazolam, glipizide). May reduce bioavailability with antacids.

Pregnancy: Ranitidine crosses the placenta. But there is no evidence of impaired fertility or harm to the foetus due to Ranitidine. Like other drugs, Ranitidine should only be used during pregnancy if considered essential.

Lactation: Ranitidine is excreted in human breast milk. Caution should be exercised when the drug is administered to a nursing mother.

Use in elderly patients: In clinical trial the ulcer healing rates have been found similar in patients age 65 and over with those in younger patients. Additionally, there was no difference in the incidence of adverse effects.

Ranitidine is very specific in action and accordingly no particular problems are expected following overdosage with the drug. Symptomatic and supportive therapy should be given as appropriate. If required, the drug may be removed from the plasma by haemodiaiysis.

Slow IV inj: Ranitidine 50 mg diluted to a concentration ≤2.5 mg/mL (e.g. total of 20 mL) with NaCl 0.9% inj or dextrose 5% or 10%, lactated Ringer's, Na bicarbonate 5% soln.

Intermittent slow IV infusion: Ranitidine 50 mg diluted to a concentration ≤0.5 mg/mL (e.g. total of 100 mL) of dextrose 5% inj or NaCl 0.9%, lactated Ringer's, Na bicarbonate 5% soln.

Continuous IV infusion: Ranitidine 150 mg diluted in 250 mL of dextrose 5% inj or NaCl 0.9%, lactated Ringer's, Na bicarbonate 5% soln.

Patients with Zollinger-Ellison syndrome or other hypersecretory conditions: Ranitidine should be diluted to a concentration ≤2.5 mg/mL with dextrose 5% or NaCl 0.9%, lactated Ringer's, Na bicarbonate 5% soln.

Store in a cool and dry place. protect from light.

For treatment of iron deficiency and prevention of concomitant Folic acid deficiency in adults. For maintenance of maternal haematopoiesis during pregnancy particularly when diet is abnormal or substandard.

Iron & Vitamin Combined preparations

Iron is an essential constituent of the body being necessary for haemoglobin formation and for the oxidative processes of living tissues. Iron salts should only be given for the treatment and as prophylaxis of Iron deficiency anaemia. Iron deficiency anaemias are most often the result of chronic haemorrhage, nutritional deficiency, pregnancy or parasite infestation or malabsorption of iron.

A deficiency of Folic acid typically during pregnancy has long been known to cause a megaloblastic anaemia. The vitamin is not storable in the body and the combination of fetal demand during pregnancy and malnutrition can lead to a deficiency, hence anaemia. It has been observed that the rapid production of red blood cells following treatment with iron may deplete body folate if there is inadequate intake; combination of folic acid and ferrous fumerate avoids the complication. Iron and Folic acid are absorbed in the proximal small intestine particularly the duodenum. Ferrous Fumerate & Folic acid supplements replenish iron deficiency. Thereby arresting the anaemia process. Absorbed iron is taken upto the bone marrow's tissues that form blood cells where it is used to synthesize haemoglobin.

In anaemia: The usual dose is one tablet or capsule daily.

In severe or refractory iron deficiency anaemia: The usual dose is one tablet or capsule twice daily may be given.

In Pregnancy, it is recommended that the dose should be started at the first antenatal consultation and continued until 3 months after delivery.

Gastric distress, abdominal cramps, diarrhoea, allergic reaction.

This is contraindicated in patients with pernicious anaemia and anaemia other than those due to iron deficiency. The nature and causes of anaemia should be established. Absorption of Ferrous Fumerate & Folic acid is inhibited by Magnesium trisillicate and Antacid containing carbonate.

Administration of Ferrous Fumerate & Folic acid during the first trimester of pregnancy may be undesirable. Very few pregnant women are not protected by physiological doses of Folic acid. If anaemia is developed despite prophylaxis with Ferrous Fumerate & Folic acid, patients should be investigated further. Some postgastrectomy patients show poor absorption of iron. Care is needed when treating patients with peptic ulcer.

When Ferrous Fumerate & Folic acid combination and Tetracycline are taken concomitantly, absorption of both drugs are reduced. Concurrent administration of antacid may reduce absorption of iron. Serum anticonvulsant levels may be reduced by administration of folate.

There is no contraindication in pregnancy and lactation.

Adverse effects to Cefuroxime have occurred infrequently and have been generally mild and transient in nature. Effects reported include rashes and gastrointestinal disturbances. As with other antibiotics, prolonged use may result in the overgrowth of non susceptible organisms e.g. Candida.

Cefuroxime is contraindicated in patients with known allergy to Cephalosporins.

Cefuroxime should be given with care to patients receiving concurrent treatment with potent diuretics & who has history of colitis. Cephalosporin antibiotics may in general be given safely to patients who are hypersensitive to penicillin although cross reactions have reported. Cefuroxime has shown, that is not likely to be a problem at the recommended to dose levels.

No potentially hazardous interactions have been reported.

US FDA pregnancy category of Cefuroxime 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. Cefuroxime have been shown to be excreted in human milk. So, caution should be exercised when Cefuroxime is administered to a nursing woman.

For 750 mg intramuscular injection: Add 3 ml water for injection to vial and then shake gently for dispersion.

For 750 mg intravenous injection: Add 8 ml water for injection to vial and then shake gently for dispersion. The solution should be slowly injected directly into a vein over a 3 to 5 minutes period.

For 1.5 g intravenous injection: Add 16 ml Water for injection to vial and then shake gently for dispersion. The solution should be slowly injected directly into a vein over a 3 to 5 minutes period.

The use of freshly reconstituted solution is recommended. However, it maintains potency for at least 24 hours at room temperature or 48 hours at 5^o C

Adverse effects to Cefuroxime have occurred infrequently and have been generally mild and transient in nature. Effects reported include rashes and gastrointestinal disturbances. As with other antibiotics, prolonged use may result in the overgrowth of non susceptible organisms e.g. Candida.

Cefuroxime is contraindicated in patients with known allergy to Cephalosporins.

Cefuroxime should be given with care to patients receiving concurrent treatment with potent diuretics & who has history of colitis. Cephalosporin antibiotics may in general be given safely to patients who are hypersensitive to penicillin although cross reactions have reported. Cefuroxime has shown, that is not likely to be a problem at the recommended to dose levels.

No potentially hazardous interactions have been reported.

US FDA pregnancy category of Cefuroxime 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. Cefuroxime have been shown to be excreted in human milk. So, caution should be exercised when Cefuroxime is administered to a nursing woman.

For 750 mg intramuscular injection: Add 3 ml water for injection to vial and then shake gently for dispersion.

For 750 mg intravenous injection: Add 8 ml water for injection to vial and then shake gently for dispersion. The solution should be slowly injected directly into a vein over a 3 to 5 minutes period.

For 1.5 g intravenous injection: Add 16 ml Water for injection to vial and then shake gently for dispersion. The solution should be slowly injected directly into a vein over a 3 to 5 minutes period.

Store in a cool, dry place (below 30^o C), away from light & moisture. Keep out of the reach of children.

H2 receptor antagonist

Ranitidine competitively blocks histamine at H2-receptors of the gastric parietal cells which inhibits gastric acid secretion. It does not affect pepsin secretion, pentagastrin-stimulated intrinsic factor secretion or serum gastrin.

Ranitidine Tablet & Syrup:

Duodenal and gastric ulcer: The usual dosage is 150 mg twice daily taken in the morning and evening or 300 mg as a single daily dose at night for 4 to 8 weeks.

Reflux oesophagitis: 150 mg twice daily or 300 mg at bed time for up to 8 weeks.

Zollinger Ellison syndrome: 150 mg 3 times daily and increased if necessary up to 6 g daily in divided doses. Dosage should be continued as long as clinically indicated.

Episodic dyspepsia: 150 mg twice daily or 300 mg at bed time for up to 6 weeks.

Maintenance: 150 mg at night for preventing recurrences.

Child (peptic ulcer): 2-4 mg/kg twice daily, maximum 300 mg daily.

Ranitidine IV injection & IV Infusion:

Ranitidine injection may be given either as a slow (over a period of at least two minutes) intravenous injection of 50 mg, after dilution to a volume of 20 ml per 50 mg dose, which may be repeated every six to eight hours; or as an intermittent intravenous infusion at a rate of 25 mg per hour for two hours; the infusion may be repeated at six to eight hour intervals; or as an intramuscular injection of 50 mg (2 ml) every six to eight hours. In the prophylaxis of haemorrhage from stress ulceration in seriously ill patients or the prophylaxis of recurrent haemorrhage in patients bleeding from peptic ulceration, parenteral administration may be continued until oral feeding commences.

In the prophylaxis of upper gastrointestinal haemorrhage from stress ulceration in seriously ill patient sapriming dose of 50 mg as low as intravenous injection followed by a continuous intravenous infusion of 0.125-0.250 mg/kg/hour may be preferred. In patients considered to be at risk of developing aspiration syndrome Ranitidine injection 50 mg may be given intramuscularly or by slow intravenous injection 45 to 60 minutes before induction of general anaesthesia.

Children: The recommended oral dose for the treatment of peptic ulcer in children is 2 mg/kg to 4 mg/kg twice daily to a maximum of 300 mg ranitidine per day. Safety and effectiveness of Ranitidine injection have not been established in case of children.

Ranitidine is well tolerated and side effects are usually uncommon. Altered bowel habit, dizziness, rash, tiredness, reversible confusional states, headache, decreased blood counts, muscle or joint pain have rarely been reported.

Patients hypersensitive to Ranitidine

Ranitidine should be given in reduced dosage to patients with impaired renal and hepatic function.

Delayed absorption and increased peak serum concentration with propantheline bromide. Ranitidine minimally inhibits hepatic metabolism of coumarin anticoagulants, theophylline, diazepam and propanolol. May alter absorption of pH-dependent drugs (e.g. ketoconazole, midazolam, glipizide). May reduce bioavailability with antacids.

Pregnancy: Ranitidine crosses the placenta. But there is no evidence of impaired fertility or harm to the foetus due to Ranitidine. Like other drugs, Ranitidine should only be used during pregnancy if considered essential.

Lactation: Ranitidine is excreted in human breast milk. Caution should be exercised when the drug is administered to a nursing mother.

Use in elderly patients: In clinical trial the ulcer healing rates have been found similar in patients age 65 and over with those in younger patients. Additionally, there was no difference in the incidence of adverse effects.

Ranitidine is very specific in action and accordingly no particular problems are expected following overdosage with the drug. Symptomatic and supportive therapy should be given as appropriate. If required, the drug may be removed from the plasma by haemodiaiysis.

Slow IV inj: Ranitidine 50 mg diluted to a concentration ≤2.5 mg/mL (e.g. total of 20 mL) with NaCl 0.9% inj or dextrose 5% or 10%, lactated Ringer's, Na bicarbonate 5% soln.

Intermittent slow IV infusion: Ranitidine 50 mg diluted to a concentration ≤0.5 mg/mL (e.g. total of 100 mL) of dextrose 5% inj or NaCl 0.9%, lactated Ringer's, Na bicarbonate 5% soln.

Continuous IV infusion: Ranitidine 150 mg diluted in 250 mL of dextrose 5% inj or NaCl 0.9%, lactated Ringer's, Na bicarbonate 5% soln.

Patients with Zollinger-Ellison syndrome or other hypersecretory conditions: Ranitidine should be diluted to a concentration ≤2.5 mg/mL with dextrose 5% or NaCl 0.9%, lactated Ringer's, Na bicarbonate 5% soln.

Store in a cool and dry place. protect from light.

Osmotic purgatives

Lactulose is a synthetic disaccharide. Lactulose is metabolized in the colon by the saccharolytic bacteria, producing low molecular weight organic acids (mainly lactic acid), which lowers the pH of the colon contents, promote the retention of water by an osmotic effect; thus increasing peristaltic activity. Lactulose is minimally absorbed; therefore, the pharmacokinetics of the absorbed material are not relevant to the principal therapeutic action.

In constipation ( chronic constipation):

• Adults: Initially 3-6 tea-spoons daily, In long-term therapy 1½-6 tea-spoons daily
• Children up to 14 years: Initially 3 tea-spoons daily, In long-term therapy 1-2 tea-spoons daily
• Infants and toddlers: Initially 1-2 tea-spoons daily, In long-term therapy 1 tea-spoon daily

In damaged intestinal flora:

• Adults: 1-2 tea-spoons daily
• Children: 1 tea-spoon daily

For reduction of blood ammonia level:

• Hyper-ammoniemia in hepatopathy: a maximum of 18-30 tea-spoons daily.
• In portal systemic encephalopathy: hourly doses of 6-9 tea-spoons of Lactulose solution may be used to induce the rapid laxation. When the laxative effect has been achieved, the dose may then be reduced.

Occasionally flatulence, cramp and abdominal discomfort can occur at the beginning of treatment; this is rapidly eliminated by reducing the dose. Overdose can result in diarrhoea. In abuse, loss of electrolytes (primarily potassium).

Hypersensitivity to either galactose and or lactose; galactose-free diet, gastro-cardial symptom complex, suspected intestinal obstruction.

Lactulose should be administered with care to patients who are intolerant to lactulose. The dose used in the treatment of (pre) coma hepaticum is usually much higher and may need to be taken into consideration for diabetics.

There is no significant drug interactions with lactulose. The glycosidic effect of cardiac glycosides can be intensified by potassium deficiency in abuse.

US FDA Pregnancy Category of Lactulose is B. Studies show that Lactulose has no adverse effects. Decisions regarding use during pregnancy and lactation must be made by registered physician.

There have been no reports of accidental overdosage. In the event of acute overdosage it is expected that diarrhoea and abdominal cramps would be the major symptoms.

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

Glucocorticoids

Prednisolone is a synthetic adrenocortical drug with predominantly glucocorticoid properties. Prednisolone directly inhibits the action of the Phospholipase A2 enzyme which is responsible for the production of different inflammatory mediators like Leukotrienes, SRS-A, Prostaglandins etc. Prednisolone is rapidly and well absorbed from the Gl tract following oral administration. Prednisolone is 70- 90% protein-bound in the plasma and it is eliminated from the plasma with a half-life of 2 to 4 hours. It is metabolized mainly in the liver and excreted in the urine.

Adult-
Nephrotic Syndrome:

• Initial: 2 mg/kg/day (maximum 80 mg/day) in divided doses 3 to 4 times/day until urine is protein free for 3 consecutive days (maximum: 28 days); followed by 1 to 1.5 mg/kg/dose given every other day for 4 weeks.
• Maintenance dose: 0.5 to 1 mg/kg/ dose given every other day for 3 to 6 months.

Anti-inflammatory: 5 to 60 mg per day in divided doses 1 to 4 times/day.

Acute Asthma: 40-60 mg/day PO in single daily dose or divided q12 hr for 3-10 days.

Allergic Conditions:

• Day 1: 10 mg PO before breakfast, 5 mg after lunch and after dinner, and 10 mg at bedtime.
• Day 2: 5 mg PO before breakfast, after lunch, and after dinner and 10 mg at bedtime.
• Day 3: 5 mg PO before breakfast, after lunch, after dinner, and at bedtime.
• Day 4: 5 mg PO before breakfast, after lunch, and at bedtime.
• Day 5: 5 mg PO before breakfast and at bedtime.
• Day 6: 5 mg PO before breakfast.

Pediatric-
Asthma:

• 1 to 4 years: Acute: 20 mg orally every 12 hours. Maintenance: 20 mg orally every other day.
• 5 to 12 years: Acute: 30 mg orally every 12 hours. Maintenance: 30 mg orally every other day.
• 12 years: Acute: 40 mg orally every 12 hours. Maintenance: 40 mg orally every other day.

Anti-inflammatory: 0.05 to 2 mg/kg/day divided 1 to 4 times/day.

Immunosuppression: 0.05 to 2 mg/kg/day divided 1 to 4 times/day.

Common side effects include increased appetite, indigestion, nervousness or restlessness. Less frequent or rare side effects are darkening or lightening of skin color, dizziness or lightheadedness, flushing of face or cheeks, hiccups, increased sweating, the sensation of spinning.

Systemic infections unless specific anti-infective therapy is employed. Hypersensitivity to any ingredient. Ocular herpes simplex because of possible perforation.

Precaution has to be taken in diabetes, hypertension, Psychological disturbances, osteoporosis, post-menopausal women, pregnancy and in chronic nephritis. Long-term use of Prednisolone can cause Cushing's habitus, hyperglycemia, muscular weakness, increased susceptibility to infection, delayed wound healing, and psychiatric disturbances.

The efficacy of prednisolone is reduced by Aminoglutethimide, Antacids, Barbiturates, Carbamazepine, Griseofulvin, Mitotane, Phenylbutazone, Phenytoin, Primidone and Rifampin. Prednisolone reduces the amount of potassium in the blood. Digitalis can cause Cardiac arrhythmias if hypokalemia occurs. Immunization should be done very carefully.

This medicine is not recommended for use during pregnancy unless considered essential by your doctor. It should only be used if the expected benefit to the mother is greater than any possible risk to the foetus. Corticosteroids appear in breast milk and could suppress growth, interfere with endogenous corticosteroid production or cause other unwanted effects.

Adverse effects related to prednisone normally develop only after prolonged use of doses in excess of the normal physiological requirement. Treatment is symptomatic and where possible the prednisone dose should be reduced gradually.

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

Drugs for subcutaneous and mycoses, Drugs used in Vaginal and Vulval condition

Nystatin is an antifungal antibiotic. Which has fungistatic or fungicidal activity against variety of pathogenic and nonpathogenic yeast and fungi, including Candida albicans. Nystatin exerts its antifungal activity by binding to sterols in the fungal cell membrane. As a result of binding, the membrane is no longer able to function as a selective barrier, and potassium and other cellular constituents are lost. It is poorly absorbed from the gastrointestinal tract.

Children:

• In intestinal and oral candidiasis (thrush): 1,00,000 units (1 ml) should be dropped into the mouth four times daily.The longer the suspension is kept in contact with the affected area in the mouth, before swallowing, the greater will be its effect.
• For prophylaxis in the newborn: The suggested dose is 1,00,000 units (1 ml) once daily or as prescribed by the physician.

Adult:

• For the treatment of intestinal or esophageal candidiasis: 5,00,000 units (5 ml) by mouth 3 or 4 times daily. The dose may be doubled, if required.
• For prophylaxis of intestinal candidiasis in adults: 10,00,000 units (10 ml) daily.
• For prophylaxis to suppress the over growth of Candida albicans in patients receiving broad spectrum antibiotic therapy: 10,00,000 units (10 ml) daily.
• For the treatment of dental sores and oral infection: 1,00,000 units (1 ml) suspension should be dropped into the mouth four times daily.

Elderly: Older people with intestinal candidiasis who are unable to swallow tablets should be given 5,00,000 units (5 ml) suspension four times daily.

Nausea, vomiting and diarrhoea have occasionally been reported with high doses of Nystatin. No systemic effects or allergic reactions have been associated with its oral dose.

There is no known contraindication to the use of Nystatin.

Absorption from the gastrointestinal tract is negligible, therefore no special precaution is required to apply in pregnancy and lactation.

Absorption of Nystatin from the gastrointestinal tract is negligible, therefore no special precautions apply in pregnancy.

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

Magnesium Hydroxide suspension is used in constipation, heart burn, gas and nausea. It is also indicated in acute and long acting constipation due to hyper acidity and peptic ulcer or stomatitis.

Antacid with laxative action

Magnesium Hydroxide is popularly known as Milk of Magnesia. It is a mildly acting antacid and laxative. It is poorly and slowly absorbed and acts by its osmotic properties in the luminal fluid which causes retention of fluid in the bowel. It is useful for emptying the bowel prior to surgical, radiological and colonoscopic procedures and can help to eliminate parasites following appropriate therapy and toxic material in some cases of poisoning. Magnesium Hydroxide is converted into Magnesium Chloride in the stomach without forming carbon dioxide

As Laxative:

• Adults: 2-4 Tablespoonful with a full glass of water.
• Children: 6-11 years: 1-2 Tablespoonful with a full glass of water. 2-5 years: 1-3 Teaspoonful with a full glass of water.

As Antacid:

• Adults: 1-3 teaspoonful (5 to 15 ml) up to 4 times daily with water.
• Children: 1-3 years: ¼ teaspoonful. 3-6 years: ¼-½ teaspoonful. 6-12 years: ½-1 teaspoonful

Magnesium Hydroxide in common with other magnesium salts may cause diarrhoea.

Magnesium Hydroxide should not be administered where use of laxative is contraindicated. Long term treatment of Magnesium Hydroxide is contraindicated in patients with renal failure.

The drug should be avoided if possible in patients with renal and hepatic failure and in those with heart block and myocardial disease. The drug may be used cautiously in pregnancy.

Magnesium hydroxide can decrease the absorption of other drugs such as, digoxin, mycophenolate, phosphate supplements (e.g., potassium phosphate), tetracycline antibiotics, certain azole antifungals (ketoconazole, itraconazole), and quinolone antibiotics (e.g., ciprofloxacin, levofloxacin).

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

Ozenoxacin is indicated for the topical treatment of impetigo due to Staphylococcus aureus or Streptococcus pyogenes in adult and pediatric patients 2 months of age and older.

Topical Antibiotic preparations

Mechanism of Action: Ozenoxacin is a quinolone antimicrobial drug. The mechanism of action involves the inhibition of bacterial DNA replication enzymes, DNA gyrase A and topoisomerase IV. Ozenoxacin has been shown to be bactericidal against S. aureus and S. pyogenes organisms.

Absorption: Four pharmacokinetic studies were conducted in 110 patients utilizing varying strengths of ozenoxacin cream, up to 2% (twice the concentration of the marketed formulation). Three of these studies assessed systemic absorption in healthy subjects and in subjects with impetigo. These studies were conducted with either single or repeated application of up to 1 g ozenoxacin cream to intact or abraded skin (up to 200 cm² surface area). No systemic absorption was observed in 84 of 86 subjects, and negligible systemic absorption was observed at the level of detection (0.489 ng/mL) in 2 subjects.

Distribution: Plasma protein binding of ozenoxacin was moderate (~80 to 85%) and did not appear to be dependent on concentration. Since negligible systemic absorption was observed in clinical studies, tissue distribution has not been investigated in humans.

Metabolism: Ozenoxacin was not metabolized in the presence of fresh human skin discs and was minimally metabolized in human hepatocytes.

Excretion: Studies have not been investigated in humans due to the negligible systemic absorption observed in clinical studies.

Apply a thin layer of Ozenoxacin topically to the affected area twice daily for five days. The affected area may be up to 100 cm² in adult and pediatric patients 12 years of age and older or 2% of the total body surface area and not exceeding 100 cm² in pediatric patients less than 12 years of age.

• Wash hands after applying Ozenoxacin cream.
• Ozenoxacin cream is for topical use only.
• Not for oral, ophthalmic, intranasal, or intravaginal use.
• The treated area may be covered with a sterile bandage or gauze dressing.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety profile of Ozenoxacin was assessed in two clinical trials (Trial 1 and Trial 2) in 362 adult and pediatric patients two months of age and older with impetigo. The patients used at least one dose from a 5-day, twice a day regimen of Ozenoxacin. Control groups included 361 patients who used placebo and 152 patients who used retapamulin ointment. The median age of the patients enrolled in the clinical trials was 10 years; 3 % of patients were 2 months to less than 2 years of age, 55 % of patients were 2 to less than 12 years of age, 11 % of patients were 12 to less than 18 years of age, and 31 % of patients were 18 years of age or older. Adverse reactions (rosacea and seborrheic dermatitis) were reported in 1 adult patient treated with Ozenoxacin.

None

Potential for Microbial Overgrowth: The prolonged use of Ozenoxacin may result in overgrowth of nonsusceptible bacteria and fungi. If such infections occur during therapy, discontinue use and institute appropriate supportive measures.

Pregnancy: There are no available data on the use of ozenoxacin in pregnant women to inform a drug associated risk. Systemic absorption of ozenoxacin in humans is negligible following topical administration of ozenoxacin (up to twice the concentration of the marketed formulation). Due to the negligible systemic exposure, it is not expected that maternal use of ozenoxacin will result in fetal exposure to the drug. Animal reproduction studies were not conducted with ozenoxacin. However, toxicity studies conducted in pregnant rats and rabbits administered the oral form of ozenoxacin showed no significant adverse developmental effects (at >10,000 times the maximum human plasma concentration seen with dermal application of ozenoxacin). The estimated background risk of major birth defects and miscarriage for the indicated population are unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Lactation: No data are available regarding the presence of ozenoxacin in human milk, and the effects of ozenoxacin on the breastfed infant or on milk production. However, breastfeeding is not expected to result in exposure of the child to ozenoxacin due to the negligible systemic absorption of ozenoxacin in humans following topical administration of ozenoxacin. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for ozenoxacin and any potential adverse effects on the breast-fed child from ozenoxacin or from the underlying maternal condition.

Pediatric Use: The safety and effectiveness of ozenoxacin in the treatment of impetigo have been established in pediatric patients 2 months to 17 years of age. Use of ozenoxacin in pediatric patients (2 months to 17 years of age) is supported by evidence from adequate and well-controlled studies of ozenoxacin in which 251 pediatric patients received at least one dose of ozenoxacin. The median age of the patients enrolled in the clinical trials was 10 years; 3% of patients were 2 months to less than 2 years of age, 55 % of patients were 2 to less than 12 years of age, 11% of patients were 12 to less than 18 years of age, and 31 % of patients were 18 years of age or older. In these studies, the maximum dose applied was approximately 0.5 g of ozenoxacin applied twice daily for up to 5 days (i.e., up to 10 applications total). The safety profile of ozenoxacin in pediatric patients 2 months and older was similar to that of adults. The safety and effectiveness of ozenoxacin in pediatric patients younger than 2 months of age have not been established.

Geriatric Use: Clinical studies of ozenoxacin did not include sufficient numbers of subjects aged 65 and older to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients.

Any sign or symptom of overdose, either topically or by accidental ingestion, should be treated symptomatically. No specific antidote is known.

Store at 20ºC - 25ºC; excursions permitted to 15ºC to 30ºC. Keep away from light & moisture. Keep out of the reach of children.

Pantoprazole is indicated where suppression of acid secretion has therapeutic benefit; i.e 

• Peptic ulcer diseases
• Gastroesophageal reflux diseases
• Ulcer induced by non-steroidal anti-inflammatory drugs (NSAIDs)
• Eradication of Helicobacter pylori (in combination with antibiotics)
• Zollinger-Ellison Syndrome

Proton Pump Inhibitor

Pantoprazole is a proton pump inhibitor that suppresses the final step in gastric acid production by covalently binding to the H⁺/K⁺ATPase enzyme system at the surface of the gastric parietal cell. This effect leads to inhibition of both basal and stimulated gastric acid secretion, irrespective of the stimulus that persists longer than 24 hours.

Oral:

• Benign gastric ulcer: 40 mg daily in the morning for 4 weeks, continued for further 4 weeks, if not fully healed.
• Gastro-esophageal reflux disease: 20-40 mg daily in the morning for 4 weeks, continued for further 4 weeks, if not fully healed; maintenance dose is 20 mg daily, which may be increased to 40 mg daily.
• Duodenal ulcer: 40 mg daily in the morning for 2 weeks, continued for further 2 weeks if not fully healed.
• Duodenal ulcer associated with Helicobacter pylori: Pantoprazole is recommended at a dose of 40 mg twice daily in association with antimicrobial agents as detailed below: Amoxycillin 1 g and Clarithromycin 500 mg both twice daily for one week, or Clarithromycin 250 mg and Metronidazole 400 mg both twice daily for one week.
• Prophylaxis of NSAID-associated gastric or duodenal ulcer: 20 mg daily for those require long-term NSAID treatment.
• Zollinger-Ellison Syndrome: Initially 80 mg once daily adjusted according to response (elderly max. 40 mg daily); daily doses above 80 mg given in 2 divided doses.

IV Injection:

• Duodenal ulcer and gastric ulcer: 40 mg once daily for 7-10 days
• Gastroesophageal reflux disease associated with a history of erosive esophagitis: 40 mg once daily for 7-10 days
• Prevention of rebleeding in peptic ulcer: IV 80 mg, followed by 8 mg/hour infusion for 72 hours
• Prophylaxis of acid aspiration: 80 mg IV every 12 h for 24 h, followed by 40mg every 12 hour
• Long-term management of Zollinger-Ellison Syndrome and other pathological hypersecretory conditions: 80 mg IV every 12 hours, may increase to 80 mg every 8 hours if needed, may titrate to higher doses depending on acid output.

Pantoprazole is well tolerated in both short-term and long-term treatment. Headache and diarrhea are the common side effects and rarely included side effects are abdominal pain, flatulence, rash, insomnia and hyperglycemia.

Pantoprazole is contraindicated in patients with known hypersensitivity to any of the components of the formulation.

Patients should be cautioned that Pantoprazole tablet should not be split, chewed or crushed. Long-term therapy of Pantoprazole may lead to malabsorption of cyanocobalamin (Vitamin B12) or may increase the risk of osteoporosis related disorders.

No significant drug interactions have been observed in clinical studies.

US FDA Pregnancy Category of Pantoprazole is B. There are, however, no adequate and well-controlled studies in pregnant woman. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Pantoprazole has been shown to be excreted in human milk. So, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the benefit of the drug to the mother.

There are no known symptoms of overdosage in humans. Since Pantoprazole is highly protein bound, it is not readily dialyzable. Apart from symptomatic and supportive management, no specific therapy is recommended.

Direction for use of IV injection: Pantoprazole lyophilized powder and 0.9% Sodium Chloride Injection is for intravenous administration only and must not be given by any other route. Pantoprazole IV injection should be given as a slow intravenous injection. The solution for IV injection is obtained by adding 10 ml 0.9% Sodium Chloride Injection to the vial containing powder. After reconstitution the injection should be given slowly over a period of at least 2 to 5 minutes. Use only freshly prepared solution. The reconstituted solution may be stored at room temperature (up to 30° C) for a maximum 4 hours.

Direction for use of IV infusion: Pantoprazole IV infusion should be given as an intravenous infusion over a period of approximately 15 minutes. Pantoprazole IV infusion should be reconstituted with 10 ml of 0.9% Sodium Chloride Injection and further diluted (admixed) with 0.9% Sodium Chloride Injection or 5% Dextrose or Lactated Ringer's Injection to a final volume of 100 ml. The reconstituted solution may be stored at room temperature (up to 30° C) for a maximum 4 hours prior to further dilution. The admixed solution may be stored at room temperature (up to 30° C) and must be used within 24 hours from the time of initial reconstitution.

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

Chloroquine Phosphate is indicated in the following cases:

• Treatment of malaria
• Prophylaxis and suppression of malaria
• Treatment of amoebic hepatitis and abscess
• Treatment of discoid and systemic and systemic lupus erythematosus
• Treatment of rheumatoid arthritis

Anti-malarial drugs

Chloroquine is used for malarial prophylaxis (as a suppressive) and in managing acute attacks of malaria. It is highly active against erythrocytic forms of P. vivax, P. malariae and P. falciparum. It influences Hb digestion by increasing intravesicular pH in malaria parasite cells and interferes with the nucleoprotein synthesis of the patient. It is also effective in extra intestinal amoebiasis. In RA chloroquine and more effectively hydroxychloroquine have a disease-modifying effect.

Treatment of Malaria-

Partially immune adults:

A single dose of 4 tablets. In severe attacks, the dosage schedule for non-immune adults should be adopted.

Partially immune children:

• Under 1 year: 1-2 single dose (in 5 ml spoonful)
• 1-3 years: 3-4 single dose (in 5 ml spoonful)
• 3-6 years: 4-6 single dose (in 5 ml spoonful)
• 6-9 years: 6-9 single dose (in 5 ml spoonful)

In severe attacks, the dosage schedule for non-immune children should be adopted.

Non-immune adults:

• P. falciparum infections: 4 tablets initially, 2 tablets after 6 to 8 hours and then 2 tablets per day for 2 days
• P. vivax group infections: A single dose of four tablets followed by a course of treatment with primaquine phosphate (15 mg base daily for fourteen days)

Non-immune Children:

Under 1 year:

• 1-2 initial dose (in 5 ml spoonful)
• 1 dose to be taken 6 hours later and then daily for 2 days (in 5 ml spoonful)

1-3 years:

• 3-4 initial dose (in 5 ml spoonful)
• 1-2 dose to be taken 6 hours later and then daily for 2 days (in 5 ml spoonful)

3-6 years:

• 4-6 initial dose (in 5 ml spoonful)
• 2-3 dose to be taken 6 hours later and then daily for 2 days (in 5 ml spoonful)

6-9 years :

• 6-9 initial dose (in 5 ml spoonful)
• 3-5 dose to be taken 6 hours later and then daily for 2 days (in 5 ml spoonful)

Prophylaxis and suppression of Malaria-

Adults: 2 tablets taken once a week, on the same day each week, during exposure to risk and continued for 6 weeks after leaving the malarious area.

Children (Syrup): The following doses should be taken once a week, on the same day each week, during exposure to risk and continued for 6 weeks after leaving the malarious area.

• Under 1 year: 1 single dose (in 5 ml spoonful)
• 1-3 years: 2 single dose (in 5 ml spoonful)
• 3-6 years: 2-3 single dose (in 5 ml spoonful)
• 6-9 years: 3-5 single dose (in 5 ml spoonful)

Children (Tablets): For practical purpose, children over 12 years may be treated as adults and for those below this age, the following proportions may be applied.

• Under 1 year: ⅛ adult dose (¼ tablet)
• 1-4 years: ¼ adult dose (½ tablet)
• 4-8 years: ½ adult dose (1 tablet)
• 8-12 years: ¾ adult dose (1.5 tablet)

Choroquine is well tolerated at the standard dosage regimens, side effects such as headache and gastrointestinal disturbances which may occur are not of a serious nature. Where prolonged high dose is required side effects can be of greater severity and patients may develop skin eruptions, occasional depigmentation or loss of hair, difficulty in accommodation, blurring of vision. Corneal opacities disappear completely when the drug is stopped. Rarely thrombocytopenia, agranulocytosis and aplastic anemia have been reported.

The most serious toxic hazard of prolonged therapy with doses is the occasional development of irreversible retinal damage. For this reason considerable caution is needed in the use of choroquine for long-term high dosage therapy and such use should only be considered when no other drug is available. Defects in visual accommodation may occur on first taking choloquine and patients should be warned regarding driving or operating machinery.

There is no absolute contraindication to the use of chloroquine.

Caution is necessary when giving choroquine to patients with porphyria who also have hepatic dysfunction or cirrhosis as the drug may precipitate severe constitutional symptoms and an increase in the amount of porphyrins excreted in the urine. This reaction is especially apparent in alcoholics. Patients receiving choloquine continuously at higher dose levels for a period longer than 12 months or at weekly intervals for a period of more than 3 years as prophylactic against malaria (or the consumption exceeds 1.6 g/Kg) should undergo ophthalmic examination at three months interval.

Concomitant therapy with phenylbutazone predisposes to dermatitis, antagonises effect of neostigmine and pyridostigmine, reduces bioavailability of ampicillin. Cimetidine inhibits metabolism of chloroquine raising plasma levels.

As with all other drugs, the use of choroquine during pregnancy should be avoided if possible, unless in the case of threatening infections, in the judgment of the physician, when the potential benefit outweighs the risk.

Amoebic hepatitis: Four tablets daily for two days followed by one tablet twice daily for two or three weeks.

Lupus erythomatosus: One tablet twice daily for one to two weeks followed by a maintenance dose of one tablet daily.

Store at room temperature in a dry place, away from light.

Chloroquine Phosphate is indicated in the following cases:

• Treatment of malaria
• Prophylaxis and suppression of malaria
• Treatment of amoebic hepatitis and abscess
• Treatment of discoid and systemic and systemic lupus erythematosus
• Treatment of rheumatoid arthritis

Anti-malarial drugs

Chloroquine is used for malarial prophylaxis (as a suppressive) and in managing acute attacks of malaria. It is highly active against erythrocytic forms of P. vivax, P. malariae and P. falciparum. It influences Hb digestion by increasing intravesicular pH in malaria parasite cells and interferes with the nucleoprotein synthesis of the patient. It is also effective in extra intestinal amoebiasis. In RA chloroquine and more effectively hydroxychloroquine have a disease-modifying effect.

Treatment of Malaria-

Naproxen is indicated for the relief of sign and symptoms of rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, juvenile arthritis, tendonitis, bursitis & acute gout. It is also indicated for the management of primary dysmenorrhea & pain.

Drugs for Osteoarthritis, Drugs used for Rheumatoid Arthritis, Non-steroidal Anti-inflammatory Drugs (NSAIDs)

Naproxen is a non steroidal anti-inflammatory drug (NSAID) with anti-inflammatory, analgesic & antipyretic properties. It is rapidly absorbed from the gastrointestinal tract and achieves 95% bioavailability.

Naproxen Tablet-

• Rheumatoid arthritis, osteoarthritis and ankylosing spondylitis: The usual dose is 500-1000 mg daily in two divided doses after meals.
• Management of pain, primary dysmenorrhea, acute tendonitis & bursitis: Recommended starting dose is 500 mg followed by 500 mg every 12 hours or 250 mg every 6-8 hours. The initial total daily dose should not exceed 1250 mg and thereafter, the total daily dose should not exceed 1000 mg.
• Acute gout: Recommended starting dose is 750 mg followed by 250 mg every 8 hours until the attack has subsided.

Naproxen Suspension-

• For Juvenile rheumatoid arthritis: The usual dose for children over 2 years is 10 mg/kg/day given as two divided doses at 12-hours intervals. Therapy in children under 2 years of age is not recommended.

Naproxen Gel-

• Is to be applied 2-6 times a day as required and is not recommended for use in children.

Most frequently reported side effects include following:

• Gastrointestinal: Heartburn, abdominal pain, nausea, diarrhea, dyspepsia.
• Central Nervous System: Headache, vertigo, drowsiness.
• Dermatological: Pruritus (itching), purpura.
• Cardiovascular: Edema, palpitation.
• Others: Visual disturbances, hearing disturbances.

Naproxen is contraindicated in patients with known hypersensitivity to Naproxen. It should not be given to patients who have experienced asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs. It is contraindicated for the treatment of perioperative pain in the setting of coronary artery bypass graft (CABG) surgery.

ACE inhibitors: diminish the antihypertensive effect of ACE inhibitors.
Antacids & Sucralfate: delay the absorption of Naproxen.
Aspirin: increase adverse effects.
Diuretics: reduce the natriuretic effect of Furosemide and Thiazides.
Methotrexate: enhance the toxicity of Methotrexate.
Warfarin: increase the risk of GI bleeding.
Selective Serotonin Reuptake Inhibitors (SSRI): increase the risk of GI bleeding.

US FDA pregnancy category of Naproxen is C. So, Naproxen should be avoided in pregnancy & lactation unless the potential benefits to the other outweigh the possible risks to the fetus.

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

Eye Anti-Infectives & Antiseptics, Tetracycline group of drugs, Topical antibiotics for Acne

Oxytetracycline inhibits cell growth by inhibiting translation. It binds to the 30S ribosomal subunit and prevents the amino-acyl tRNA from binding to the A site of the ribosome. The binding is reversible in nature. Oxytetracycline is lipophilic and can easily pass through the cell membrane or passively diffuses through porin channels in the bacterial membrane.

Adults: 250-500 mg every 6 hours. Food, milk and some dairy products interfere with the absorption of Tetracyclines. So Tetracyclines should be given one hour before or two hours after meals.

Side effects of Oxytetracycline, which have been reported in some patients, are anorexia, nausea, vomiting, diarrhoea, glossitis, skin rashes and urticaria.

Oxytetracycline should not be used with patients who are hypersensitive to Tetracyclines. It should not be used in children under 12 years of age. It is contraindicated in pregnant women because of tooth staining in the fetus and possible growth retardation effects.

Oxytetracycline should be used with caution in renal impairment.

Antacids containing Aluminium, Calcium, Magnesium, Zinc or Iron salts may impair the absorption of Oxytetracycline. In long term therapy, Tetracyclines depress plasma prothrombin activity and reduced doses of concomitant anticoagulants may be necessary. A few cases of pregnancy or breakthrough bleeding have been attributed to the concurrent use of Tetracyclines or Oxytetracyclines with oral contraceptives.

Results of animal studies indicate that tetracyclines cross the placenta, are found in fetal tissues and can have toxic effects on the developing fetus. Evidence of embryotoxicity has also been noted in animals treated early in pregnancy. Tetracyclines are present in the milk of lactating women who are taking a drug in this class.

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

Levosalbutamol is indicated for the treatment or prevention of bronchospasm in adults, adolescents and children 6 years of age and older with reversible obstructive airway disease.

Short-acting selective & β2-adrenoceptor stimulants

Levosalbutamol is a single isomer beta 2-agonist that differs from racemic salbutamol by elimination of (S)-salbutamol. Levosalbutamol is an effective bronchodilator whose primary mechanism of action is unimpeded by (S)-salbutamol. Thus, when compared with racemic salbutamol, clinically comparable bronchodilation can be achieved with doses that substantially lessen beta-mediated side effects.

Tablet-

• Adults and adolescents above 12 years: 1-2 mg three times daily.
• Children (6 -11 years): 1 mg three times daily.

Syrup-

• Adults : 5-10 ml three times daily.
• Childrn (6-11 years): 5 ml three times daily.

Hypocalcaemia, palpitation, fine tremors of the skeletal muscle and muscle cramps may occur. The other likely side effects are nausea, vomiting, burning substernal or epigastric pain and diarrhoea.

Levosalbutamol is contraindicated in patients with a history of hypersensitivity to levosalbutamol or any of its components.

Particular caution is advised in acute severe asthma as this effect may be potentiated by hypoxia and by concomitant treatment with xanthine derivatives, steroids and diuretics. Serum potassium levels should be monitored in such situations.

Other short acting sympathomimetic bronchodilators or epinephrine should be used with caution with Levosalbutamol. If additional adrenergic drugs are to be administered by any route, they will be used with caution to avoid deleterious cardiovascular effects.

The drug should be used during pregnancy only if the potential benefit justifies the potential risk of the fetus. It is not known whether Levosalbutamol is excreted in human milk. Caution should be exercised when oral Levosalbutamol is administered to a nursing woman.

The expected symptoms with over dosage are those of excessive beta-adrenergic stimulation and the symptoms listed under side effects. In the event of serious poisoning, the stomach should be emptied and, if necessary, a beta-blocker administered with caution in patients with a history of bronchospasm.

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