Drug Mechanism: How does Azithromycin work?

Azithromycin 250 mg is effective against a wide variety of bacteria organisms such as Hemophilus influenzae, Streptococcus pneumoniae, Mycoplasma pneumoniae, Staphylococcus aureus, and mycobacterium avium, and many others.

It is unusual in that it stays in the body for quite a while, allowing for once a day dosing and for shorter treatment courses for most infections.

Azithromycin 250 mg 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.
