Disclosed herein are oral care compositions comprising a peroxide whitening complex in an amount to provide from 3.5% to 7% of hydrogen peroxide by weight of the composition, and a block copolymer of ethylene oxide and propylene oxide in an amount of from 40% to 60% by weight of the composition. Methods of making and using the dentifrices are also provided.

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.
