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.

Second generation Cephalosporins

Cefuroxime is a bactericidal second generation cephalosporin antibiotic which is active against a wide range of Gram-positive and Gram-negative susceptible organisms including many beta-lactamase producing strains. Cefuroxime inhibits bacterial cell wall synthesis by interfering with the transpeptidation process.

Clavulanic acid is a naturally derived beta lactamase inhibitor produced by Streptomyces clavuligerus. It has similar structure to beta lactam antibiotics which binds irreversibly to beta-lactamase enzymes and inactivates them. Clavulanic acid gives protection of Cefuroxime from degradation by beta lactamase enzymes and provides a solution for the treatment of bacterial infections caused by beta lactam resistant bacteria.

Cefuroxime-Clavulanic Acid tablet may be taken without regard of food.

Generally Cefuroxime-Clavulanic Acid is well tolerated. However, a few side effects like nausea, vomiting, diarrhea, abdominal discomfort or pain may occur. As with other broad-spectrum antibiotics, prolonged administration of Cefuroxime and Clavulanic acid combination may result in overgrowth of nonsusceptible microorganisms. Rarely (<0.2%) renal dysfunction, anaphylaxis, angioedema, pruritis, rash and serum sickness like urticaria may appear.

Cefuroxime-Clavulanic Acid is contraindicated in patients with known allergy to cephalosporin & in patients with Pseudomembranous Colitis.

Cefuroxime should be given with care to patients receiving concurrent treatment with potent diuretics & who has history of colitis.

Concomitant administration of probenecid with Cefuroxime-Clavulanic Acid increases the area under the serum concentration versus time curve by 50%. Drug that reduces gastric acidity may result in a lower bioavailability of Cefuroxime and tend to cancel the effect of postprandial absorption.

While all antibiotics should be avoided in the first trimester if possible. However, Cefuroxime-Clavulanic Acid can be safely used in later pregnancy to treat urinary and other infections. Cefuroxime-Clavulanic Acid is excreted into the breast milk in small quantities. However, the possibility of sensitizing the infant should be kept in mind.

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

Second generation Cephalosporins

Cefuroxime is a bactericidal second generation cephalosporin antibiotic which is active against a wide range of Gram-positive and Gram-negative susceptible organisms including many beta-lactamase producing strains. Cefuroxime inhibits bacterial cell wall synthesis by interfering with the transpeptidation process.

Clavulanic acid is a naturally derived beta lactamase inhibitor produced by Streptomyces clavuligerus. It has similar structure to beta lactam antibiotics which binds irreversibly to beta-lactamase enzymes and inactivates them. Clavulanic acid gives protection of Cefuroxime from degradation by beta lactamase enzymes and provides a solution for the treatment of bacterial infections caused by beta lactam resistant bacteria.

Motility Stimulants, Motility stimulants/Dopamine antagonist, Prokinetic drugs

Domperidone is a dopamine antagonist that principally blocks the dopamine receptors located in the ChemoreceptorTrigger Zone (CTZ) and stomach. Its gastroprokinetic action is based on its blocking effect of dopamine receptors that have an influence on the motility of the gastrointestinal tract. Due to its weak penetration across the blood-brain barrier, Domperidone has almost no effect on the dopaminergic receptors in the brain, therefore, excluding psychotropic and neurologic side effects. Domperidone restores normal motility and tone of the upper gastrointestinal tract, facilitates gastric emptying, enhances antral and duodenal peristalsis and regulates contraction of the pylorus. Domperidone also increases esophageal peristalsis and lower esophageal sphincter pressure, and thus prevents regurgitation of gastric content.

Domperidone should be taken 15-30 minutes before meals and, if necessary, before retiring.

The usual recommended oral dose of Domperidone is as follows:

• Adults: 10-20 mg (1-2 tablet or 10-20 ml suspension), every 6-8 hours daily. The maximum dose of Domperidone is 80 mg daily.
• Children: 2-4 ml suspension/10 kg body weight or 0.4-0.8 ml paediatric drops/10 kg body weight, every 6-8 hours daily.

In dyspeptic symptom:

• Adults: 10-20 mg (1-2 tablet or 10-20 ml suspension), every 6-8 hours daily.
• Children: 0.2-0.4 mg/kg (2-4 ml suspension/10 kg or 0.4-0.8 ml paediatric drops/10 kg) body weight, every 6-8 hours daily.

In acute and sub-acute conditions (mainly in acute nausea and vomiting):

• Adults: 20 mg (2 tablets or 20 ml suspension), every 6-8 hours daily
• Children: 0.2-0.4 mg/kg (2-4 ml suspension/10 kg or 0.4-0.8 ml paediatric drops/10 kg) body weight, every 6-8 hours daily. (In acute nausea and vomiting maximum period of treatment is 12 weeks).

By rectum in suppositories:

• Adults (including elderly): 30-60 mg every 4-8 hours.
• Children: The maximum daily dose rectally in children's is 30 mg for those weighting 10 to 25 kg. The dose may be divided throughout day if necessary.
• The maximum period of treatment is 12 weeks.

Domperidone may produce hyperprolactinemia (1.3%).This may result in galactorrhea, breast enlargement, and soreness and reduced libido. Dry mouth (1%), thirst, headache (1.2%), nervousness, drowsiness (0.4%), diarrhea (0.2%), skin rash and itching (0.1%) may occur during treatment with domperidone. Extra-pyramidal reactions are seen in 0.05% of patients in clinical studies.

Domperidone is contraindicated to patients having known hypersensitivity to this drug and in the case of neonates. Domperidone should not be used whenever gastrointestinal stimulation might be dangerous i.e., gastrointestinal hemorrhage, mechanical obstruction or perforation. Also contraindicated in patients with prolactin releasing pituitary tumor (prolactinoma).

Domperidone should be used with absolute caution in the case of children because there may be an increased risk of extra-pyramidal reactions in young children because of an incompletely developed blood-brain barrier. Since domperidone is highly metabolized in liver, it should be used with caution in patient with hepatic impairment.

Domperidone may reduce the risk of hypoprolactemic effect of bromocriptine. The action of Domperidone on Gl function may be antagonized by antimuscarinics and opoid analgesics. Care should be exercised when domperidone is administered in combination with MAO (monoamine oxidase) inhibitors.

The safety of domperidone has not been proven and it is therefore not recommended during pregnancy. Animal studies have not demonstrated the teratogenic effect in the fetus. Domperidone may precipitate galactorrhea and improve post-natal lactation. It is secreted in breast milk but in very small quantities insufficient to be considered harmful.

There are no reported cases of overdose.

Store below 30°C, Protected from light & moisture. Keep out of children's reach.

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.

Combined antihypertensive preparations

This is a fixed-dose combination of Amlodipine and Atenolol. Amlodipine is a dihydropyridine calcium antagonist that inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle; it has a greater effect on vascular smooth muscle than on cardiac muscle. Amlodipine is a peripheral vasodilator that acts directly on vascular smooth muscle to cause a reduction in peripheral vascular resistance and reduction in blood pressure. Amlodipine reduces tone, decreases coronary vasoreactivity and lowers cardiac demand by reducing afterload.

Atenolol is a cardioselective beta-blocker. The cardio-selectivity is dose-related. Atenolol causes a reduction in blood pressure by lowering cardiac output, decreasing the plasma renin activity and sympathetic outflow from CNS. Atenolol also causes a reduction in myocardial oxygen demand by virtue of its negative inotropic and negative chronotropic effects.

The recommended dosage is Amlodipine and Atenolol 5/25 mg tablet once daily. If necessary, the dosage may be increased to 5/25 mg two tablets daily or as advised by the physicians. The dosage however should be individualized.

The combination of Amlodipine and Atenolol is well tolerated. Overall side-effects include
fatigue, headache, edema, nausea, drowsiness, anxiety and depression.

Hypersensitivity to either component, sinus bradycardia, second and higher degrees of heart block, cardiogenic shock, hypotension, congestive heart failure, poor left ventricular function.

Bronchospasm: The combination should be used with caution in patients with airway obstruction.

Renal impairment: The combination can be used in patients with renal impairment. However, caution may be necessary if the creatinine clearance is less than 30 ml/min because of possible reduction in the excretion of unchanged Atenolol.

Hepatic impairment: Caution may be necessary in the use of the combination in patients with severe liver damage because of prolongation of the elimination half-life of Amlodipine.

Drug withdrawal: Since coronary heart disease may exist without being recognized, patients should be warned against stopping the drug suddenly. Any discontinuation should be gradual and under observation.

Disopyramide: Atenolol reduces the clearance of disopyramide by 20%. Additive negative inotropic effects on the heart may be produced.

Ampicillin: at doses of 1 gm and above may reduce Atenolol levels.

Oral antidiabetics and insulin: Beta-blockers may decrease tissue sensitivity to insulin and inhibit insulin secretion e.g. in response to oral antidiabetics. Atenolol has less potential for these actions.

The combination should be used during pregnancy only if the expected benefit outweighs the potential fetal risk. The combination should not be used by nursing mothers. If its use is considered necessary, breast-feeding should be stopped.

Though not documented, hypotension and less frequently congestive cardiac failure may occur in cases of overdosage. Unabsorbed drugs may be removed by gastric lavage or administration of activated charcoal. Symptomatic treatment is suggested.

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

This is indicated in-

• Patients with essential hypertension

Amlodipine is a dihydropyridine calcium antagonist that inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle; it has a greater effect on vascular smooth muscle than on cardiac muscle. Amlodipine is a peripheral vasodilator that acts directly on vascular smooth muscle to cause a reduction in peripheral vascular resistance and reduction in blood pressure. Amlodipine reduces tone, decreases coronary vasoreactivity and lowers cardiac demand by reducing afterload.

Atenolol is a cardioselective beta-blocker. The cardio-selectivity is dose-related. Atenolol causes a reduction in blood pressure by lowering cardiac output, decreasing the plasma renin activity and sympathetic outflow from CNS. Atenolol also causes a reduction in myocardial oxygen demand by virtue of its negative inotropic and negative chronotropic effects.

The recommended dosage is Amlodipine and Atenolol 5/25 mg tablet once daily. If necessary, the dosage may be increased to 5/25 mg two tablets daily or as advised by the physicians. The dosage however should be individualized.

The combination of Amlodipine and Atenolol is well tolerated. Overall side-effects include
fatigue, headache, edema, nausea, drowsiness, anxiety and depression.

Hypersensitivity to either component, sinus bradycardia, second and higher degrees of heart block, cardiogenic shock, hypotension, congestive heart failure, poor left ventricular function.

Bronchospasm: The combination should be used with caution in patients with airway obstruction.

Renal impairment: The combination can be used in patients with renal impairment. However, caution may be necessary if the creatinine clearance is less than 30 ml/min because of possible reduction in the excretion of unchanged Atenolol.

Hepatic impairment: Caution may be necessary in the use of the combination in patients with severe liver damage because of prolongation of the elimination half-life of Amlodipine.

Drug withdrawal: Since coronary heart disease may exist without being recognized, patients should be warned against stopping the drug suddenly. Any discontinuation should be gradual and under observation.

Disopyramide: Atenolol reduces the clearance of disopyramide by 20%. Additive negative inotropic effects on the heart may be produced.

Ampicillin: at doses of 1 gm and above may reduce Atenolol levels.

Oral antidiabetics and insulin: Beta-blockers may decrease tissue sensitivity to insulin and inhibit insulin secretion e.g. in response to oral antidiabetics. Atenolol has less potential for these actions.

The combination should be used during pregnancy only if the expected benefit outweighs the potential fetal risk. The combination should not be used by nursing mothers. If its use is considered necessary, breast-feeding should be stopped.

Though not documented, hypotension and less frequently congestive cardiac failure may occur in cases of overdosage. Unabsorbed drugs may be removed by gastric lavage or administration of activated charcoal. Symptomatic treatment is suggested.

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

Doxophylline is used to treat in following indications:

• Bronchial asthma
• Bronchospasm
• Chronic obstructive pulmonary disease (COPD)
• Pulmonary disease with spastic bronchial component.

Bronchodilator, Methyl xanthine derivatives

Doxophylline is a novel bronchodilator. It structurally differs from Theophylline due to the presence of a dioxolane group in position 7. Doxophylline selectively inhibits phosphodiesterase 4 thereby relaxes bronchial smooth muscle. However, differently from Theophylline, Doxophylline appears to have decreased affinities toward adenosine A1 and A2 receptors, which may account for the better safety profile of the drug. Doxophylline is reported to inhibit platelet activating factor (PAF) and generation of leukotriene production.

Elderly: 200 mg tablet two or three times daily.

Adults: 400 mg tablet two or three times daily or as prescribed by the physician.

Children:

• >12 years of age: 10 ml syrup or 200 mg tablet two or three times daily.
• 6-12 years of age: 6-9 mg/kg body weight two times daily, i.e. if body weight is 10 kg, 3 ml (60 mg) two times daily or as prescribed by the physician.

If required daily dose of Doxophylline is 400 mg then Doxophylline SR tablet to be taken once daily or as prescribed by the physician

Doxophylline rarely causes serious side effects, however possible side effects are similar for taking excess amount of caffeine. These include: nausea, vomiting, headache, upset stomach and heartburn.

Doxophylline is contraindicated in acute myocardial infarction. It is also contraindicated in patients with hypotension, in lactating women & patients who have shown hypersensitivity to its components.

The half-life of xanthine derivatives is influenced by a number of known variables. It may be prolonged in patients with liver disease, in patients with congestive heart failure and in those patients taking certain other drugs like erythromycin, troleandomycin, lincomycin, allopurinol, cimetidine, propanolol and anti-flu vaccine. In these cases, a lower dose of Doxophylline may be needed. Phenytoin, other anticonvulsants and smoking may cause an increase in clearance with a shorter mean half-life. In these cases higher doses of Doxophylline may be needed.

Doxophylline should not be administered together with other xanthine derivatives. Toxic synergism with ephedrine has been documented for xanthines. Like other xanthines, concomitant therapy with troleandomycin, lincomycin, clindamycin, allopurinol, cimetidine, ranitidine, propranolol and anti-flu vaccine may decrease the hepatic clearance of xanthines causing an increase in blood levels. No evidence of a relationship between Doxophylline serum concentrations and toxic events have been reported.

Animal reproduction studies indicate that, Doxophylline does not cause fetal harm when administered to pregnant animals or can not affect reproduction capacity. However, since there is limited experience in human during pregnancy, xanthines should be given to pregnant women only if clearly needed. Doxophylline is contraindicated in nursing mothers.

In case of overdose severe cardiac arrhythmias and tonic-clonic seizure may occur. These effects may represent the first signs of intoxication. The appearance of side effects may require discontinuation of the treatment which, if necessary, at the physician’s discretion, may be resumed at lower doses after all signs and symptoms of toxicity have subsided.

As there is no specific antidote, in case of overdose a symptomatic treatment of cardiovascular collapse should be instituted.

Keep in a dry place away from light and heat. Keep out of the reach of children. Doxophylline should be used only on prescription of specialist physician.
