Abstract

Hypotonic microbicidal compositions including an antimicrobial, such as an antiviral compound, and a pharmaceutically acceptable carrier in a solution formulation having hypotonic osmolarity have been developed for administration rectally to the gastrointestinal mucosa. In a preferred embodiment for use in preventing or decreasing HIV infection, the microbicidal is tenofovir, or a prodrug or derivative thereof. The formulations may include additional agents such as surfactants to enhance cleansing, buffers, or preservatives. Polymers may be included for osmolarity as well as comfort.
