Mechanism of Action

Azithromycin is a semisynthetic azalide antibiotic. It blocks transpeptidation by binding to 50s ribosomal subunit of susceptible organisms and disrupting RNA-dependent protein synthesis at the chain elongation step. Absorption: Rapidly absorbed from the GI tract. Reduced by food (capsule formulation). Absolute bioavailability: Approx 34-52%. Time to peak plasma concentration: Oral tab: 2-3 hr; IV: 1-2 hr. Distribution: Extensive into the tissues (higher than those in blood), WBC (high concentrations), CSF (small amounts). Volume of distribution: 31-33 L/kg. Plasma protein binding (concentration dependent): 7-51% (oral and IV). Metabolism: Hepatic metabolism via demethylation. Excretion: Via bile (as unchanged drug and inactive metabolites); urine (approx 6% of oral dose). Terminal elimination half-life: About 68 hr.

Special Precautions

May increase the risk of torsades de pointes and fatal heart arrhythmias in patients w/ prolonged QT interval, low K or Mg blood levels, slow heart rate and medication treating abnormal heart rhythms. Impaired hepatic and renal function. Pregnancy and lactation. Monitoring Parameters Liver function tests, CBC w/ differential.
