The reference site for Azithromycin

Azithromycin is an antibiotic useful for the treatment of a number of bacterial infections. This includes middle ear infections, strep throat, pneumonia, traveler’s diarrhea, and certain other intestinal infections. It may also be used for a number of sexually transmitted infections including chlamydia and gonorrhea infections. Along with other medications, it may also be used for malaria.

WHAT IS AZITHROMYCIN?

Azithromycin is a semi-synthetic macrolide antibiotic chemically related to erythromycin and clarithromycin (Biaxin®). It is effective against a wide variety of bacteria organisms, such as Hemophilus influenzae, Streptococcus pneumoniae, Mycoplasma pneumoniae, Staphylococcus aureus, and mycobacterium avium, including many others. It is unusual in that it stays in the body for quite some time, allowing for once a day dosing and for shorter treatment courses for most infections.
Azithromycin, like all macrolide antibiotics, prevents bacteria from growing by interfering with their ability to make proteins. Due to the differences in the way proteins are made in bacteria and humans, the macrolide antibiotics do not interfere with humans’ ability to make proteins.
