Uses of Clarison: - Bacterial infections

Macrolides

Clarithromycin acts by inhibiting microsomal protein synthesis in susceptible organisms mainly by binding to the donor site on the 50S sub- unit of the bacterial ribosome and preventing translocation to that site. Clarithromycin is active against most Gram-positive bacteria and Chlamydia, some Gram-negative bacteria and Mycoplasmas. Clarithromycin’s activity is the same as, or greater than, that of erythromycin in vitro against most Gram-positive bacteria. Clarithromycin is more acid stable than erythromycin and therefore, is better tolerated. Clarithromycin has twice the activity of erythromycin against H. influenzae. Most species of Gram-negative bacteria are resistant to clarithromycin because of failure to penetrate to the target.

How to use Clarithromycin: Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. Clarithromycin may be taken with or without food, but it is better to take it at a fixed time.

Theophylline: Concomitant use of Clarithromycin who are receiving Theophylline may be associated with an increase in serum Theophylline concentrations. Terfenadine: Clarithromycin may alter the metabolism of Terfenadine.

Hypersensitivity to Clarithromycin, Erythromycin, or any of the macrolide antibiotics. Patients receiving Terfenadine who have pre-existing cardiac abnormalities or electrolyte disturbances.

Common - Abdominal pain - Diarrhea - Headache - Nausea - Taste change - Vomiting - Indigestion - Rash

Clarithromycin is not recommended for pregnant women. Breast milk from mothers receiving Clarithromycin should not be given to infants until treatment is completed.

Clarithromycin is principally excreted by the liver and kidney. Caution should be taken in administering this antibiotic to patients with impaired hepatic and renal function. Prolonged or repeated use of Clarithromycin may result in an overgrowth of non-susceptible bacteria or fungi. If superinfection occurs, Clarithromycin should be discontinued and appropriate therapy should be instituted.

Reports indicate that the ingestion of large amounts of clarithromycin can be expected to produce gastro-intestinal symptoms. One patient who had a history of bipolar disorder ingested 8 grams of clarithromycin and showed altered mental status, paranoid behaviour, hypokalemia and hypoxemia. Adverse reactions accompanying overdosage should be treated by the prompt elimination of unabsorbed drug and supportive measures. As with other macrolides, clarithromycin serum levels are not expected to be appreciably affected by haemodialysis or peritoneal dialysis.

Store in a cool and dry place, protected from light & moisture. The reconstituted suspension must be used within 7 days if kept at room temperature and within 14 days when stored in a refrigerator. Keep out of reach of children.

The drug may be used in neonates and children in appropriate doses. Breast milk from mothers receiving Clarithromycin should not be given to infants until treatment is completed. There is as yet little experience in the treatment of pregnant patients and Clarithromycin is not recommended.
