Abstract
A method for decreasing the frequency of transmission of human immunodeficiency virus or herpesviruses by administering to a human an anti-human immunodeficiency virus amount or an anti-herpesvirus amount of cellulose acetate phthalate (CAP) or hydroxypropyl methylcellulose phthalate (HPMCP), such as in micronized form, or a combination thereof, either alone or in combination with a pharmaceutically acceptable carrier or diluent. The CAP and/or HPMCP may be employed as a suspension of micronized particles and may further contain a water miscible, non-solvent for CAP or HPMCP, such as glycerol.
