Microbicides that Do More than Gel: Vaginal Rings, Tablets and Films
As alternatives to microbicide gels that must be used every day or at the time of sex, researchers are looking at other types of formulations that may be more acceptable for women to use, and for certain drugs or drug combinations, may be more optimal vehicles for their delivery. Unlike a gel, an intravaginal ring, for example, feasibly could provide protection for a month at a time. In fact, one research group has developed an intravaginal ring formulated with two anti-HIV drugs dapivirine and maraviroc that it found can deliver therapeutic levels of both drugs for up to 30 days. Other researchers have developed a vaginal film smaller than a stick of gum and as thin as a sheet of paper. The idea is that as the film would melt away drug would be dispersed to cells to protect against HIV. Laboratory tests of a similar approach an almond-shaped vaginal tablet found it can dissolve quickly yet still deliver sustained levels of anti-HIV drugs over several hours.
