What is rapamycin?

Rapamycin (also known as sirolimus) is a macrolide, a class of antibiotics that includes Biaxin (Clarithromycin), Zithromax (Azithromycin), Dificid (Fidoximycin), and Erythromycin. Macrolides inhibit the growth of bacteria and are often used in the treatment of common bacterial infections.
