Sustained-release vaginal microbicides hold out great hope for the prevention of sexual transmission of HIV from men to women. Tenofovir (TFV) -an antiretroviral drug- sustained-release vaginal compacts combining two release control systems (by drug-loading granules with hydrophobic polymers and incorporating
