Pharmacology/Pharmacokinetics/Stability â Following oral administration, azithromycin reaches peak bloodstream concentrations in 2.2 to 3.2 hours. Within 48 hours, most patients with pneumonias will be afebrile. The liver is responsible for most metabolism of azithromycin. Antibiotics fall into three major classes according to their mechanism of action: cell walls, protein synthesis, or nucleic acid synthesis. Cell wall agents attack bacterial cell walls.
Azithromycin is an acid-stable antibiotic, so it can be taken orally with no need of protection from gastric acids. It is readily absorbed, but absorption is greater on an empty stomach. Time to peak concentration (Tmax) in adults is 2.1 to 3.2 hours for oral dosage forms.
