PHARMACOLOGY
Azithromycin binds to the 23S rRNA of the bacterial 50S ribosomal subunit. It blocks protein synthesis by inhibiting the transpeptidation/translocation step of protein synthesis and by inhibiting the assembly of the 50S ribosomal subunit. Azithromycin concentrates in phagocytes and fibroblasts as demonstrated by in vitro incubation techniques. The ratio of intracellular to extracellular concentration was >30 after one hour incubation. In vivo studies suggest that concentration in phagocytes may contribute to drug distribution to inflamed tissues.

DRUG INTERACTION
Antacids containing aluminium and magnesium salts reduce rate of absorption. In patients receiving Azithromycin and antacid, Azithromycin should be taken at least 1 hour before or 2 hours after antacid. Food interactions: Food may alter absorption. There have been no pharmacokinetic drug interactions between Azithromycin and warfarin, theophylline, carbamazepine, methylprednisolone and cimetidine.
USE IN PREGNANCY AND LACTATION
Azithromycin has been assigned to pregnancy category B by the FDA. Animal studies failed to reveal evidence of fetotoxicity. There are no controlled data in human pregnancy. Azithromycin should only be given during pregnancy when benefit outweighs risk. Azithromycin is excreted into human milk. The manufacturer recommends that caution be used when administering azithromycin to nursing women. In one lactating woman receiving azithromycin 500 mg/day, azithromycin milk concentration measured 1.3 and 2.8 mcg/mL 1 hour after the first dose and 30 hours after the third dose, respectively.
