Pharmacology of Odazyth 500 mg Tablet

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

Interaction of Odazyth 500 mg Tablet

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 & Lactation

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 on pregnant women. Since animal reproduction studies are not always predictive of human response, Odazyth 500 mg Tablet should be used during pregnancy only if adequate alternatives are not available.
