Description

 WAZIT Tablets, a brand of Azithromycin, are oral antibiotics

macrolide class of antibacterial drugs and is derived from erythromycin
However, it differs chemically from erythromycin due to the incorporation of a
methyl substituted nitrogen atom into the lactone ring

 Clinical Pharmacology

Mechanism of Action: Azithromycin works by binding to the
23S  of the 50S ribosomal subunit of susceptible microorganisms This
binding inhibits bacterial protein synthesis and hinders the assembly of the
50S ribosomal subunit

 Pharmacokinetics: Azithromycin is rapidly absorbed (about
40%) after oral administration It is widely distributed in body tissues and
fluids, with intracellular and tissue levels exceeding those in the serum
Azithromycin has a relatively low cerebrospinal fluid (CSF) level It is
primarily excreted unchanged in bile, with a small portion (45%) excreted in
urine The half-life varies depending on the dosing regimen but ranges from 11 to
14 hours after a single dose, 2 to 4 days after several doses, and 59 hours
after extended release suspension
