AzithromycinÂ is anÂ azalide, a subclass ofÂ macrolideÂ antibiotics. Azithromycin is one of the world's best-selling antibiotics, marketed in theÂ United StatesÂ under the nameÂ Zithromax.
It is derived fromÂ erythromycin; however, it differs in chemical structure from erythromycin in that aÂ methyl-substitutedÂ nitrogenatomÂ is incorporated into theÂ lactoneÂ ring, thus making the lactone ring 15-membered.
Azithromycin is used to treat or prevent certainÂ bacterial infections, most often those causingmiddle ear infections,Â strep throat,Â pneumonia,Â typhoid, andÂ sinusitis. In recent years, it has been used primarily to prevent bacterial infections in infants and those with weakerÂ immune systems.
It is also effective against certain sexually transmitted infections, such asÂ non-gonococcal urethritis,Â chlamydia,Â gonorrhea, andÂ cervicitis. Recent studies have indicated it also to be effective against late-onsetÂ asthma, but these findings are controversial and not widely accepted.
