Bacterial vaginosis is a common infection of the vagina caused by an overgrowth of bacteria in the vagina. It is the most common condition for women, specifically women in their reproductive years. It is estimated that one in every three American women will get bacterial vaginosis and it is one of the most common reason women visit gynecology clinics. While bacterial vaginosis can resolve on its own without any medications, many lead to serious complications like ectopic pregnancy, pelvic inflammatory disease, or can even make women susceptible to sexually transmitted infections. Most of the time, bacterial vaginosis can successfully be treated with a short course of oral or topical antibiotics. However, topical formulation of amphotericin B is often prescribed to treat bacterial vaginosis that failed to respond to other recommended treatments.

Amphotericin B works by altering the cell permeability through the process of binding to cholesterols of the cell membrane and disrupt the membrane stability. This causes leakage of intracellular components and ultimately leads to cell death.
