the use of Azithromycin

Azithromycin prevents bacterial cells from manufacturing specific proteins necessary for their survival. It differs from other macrolides in its azalide structure. Azithromycin, as the dihydrate, is a white crystalline powder.Azithromycin is an antibiotic used in combination with other drugs as preventive to treat various bacterial infections, particularly of the sinuses, throat, and respiratory tract (such as bronchitis and pneumonia); infections of the ear; venereal disease due to chlamydial and chancroid infection; skin infections; and diarrhea associated with campylobacter and other bacteria that cause food poisoning. Also used to prevent and treat a tuberculosis-like disease known as Mycobacterium avium complex (MAC), which is common in people with advanced AIDS. Azithromycin is also used for treating cryptosporidiosis.
Azithromycin is used to treat many different infections, including acute otitis media, nonstreptococcal bacterial pharyngitis, gastrointestinal infections such as traveler's diarrhea, respiratory tract infections such as pneumonia, cellulitis, babesiosis, Bartonella infection, chancroid, cholera, donovanosis, leptospirosis, Lyme disease, malaria, Mycobacterium avium complex disease, Neisseria meningitis, pelvic inflammatory disease, pertussis, scrub typhus, toxoplasmosis, and salmonellosis. It is used to prevent bacterial endocarditis and some sexually transmitted infections.It is also effective against localized dental infections, uncomplicated skin and skin structure infections, urethritis and cervicitis and also genital ulcer disease. Azithromycin is used as a second line treatment for strep throat and for those allergic to penicillin. It has a similar antimicrobial spectrum to erythromycin, but is more effective against certain Gram-negative bacteria, in particular, Haemophilus influenzae (although it would not be the first choice of treatment in this infection). Azithromycin resistance has been described and is endemic in many areas. Long-term use in treating Staphylococcus aureus infections with azithromycin may increase bacterial resistance to this and other macrolide antibiotics.
