Antibiotic from the macrolide group, isolated in a new subgroup of azalides.
It is a semi-synthetic derivative of erythromycin.
It has a wide range of antimicrobial effects.

Compared with erythromycin, it is more active against gram-negative microorganisms, it is more stable in the acidic environment of the stomach, it is more slowly excreted from the body and lasts longer; better tolerated; to a lesser extent inhibits the cytochrome P-450 of the liver.
In high concentration it has a bactericidal effect.
Quickly absorbed in the digestive tract (stable in an acidic environment), bioavailability is about 37%, C max - 2.5-3 hours, T Ѕ - 14-68 hours; penetrates well into organs and tissues; bactericidal concentration in the focus of infectious inflammation is maintained for 5-7 days after the last dose; subjected to biotransformation in the liver, excreted mainly with bile.
Azithromycin is used for diseases caused by microorganisms sensitive to it, including sore throats, pneumonia, bronchitis, pharyngitis, laryngitis, sinusitis, otitis media, scarlet fever, erysipelas, acne, chlamydial urethritis and cervicitis, gonorrhea and non-gonorrhea borreliosis, and Lyme disease AIDS and other infectious diseases.
