The aim of this study was to develop and evaluate Zidovudine (AZT) loaded microparticulated bioadhesive vaginal gel (AZMBVG) in order to obtain a controlled-releasing, in order to obtain a controlled-release system for treatment of AIDS. AZT microparticle AZMCs was prepared by O/O single emulsion solvent evaporation method (II) and evaluated for encapsulation efficiency, drug loading, surface morphology and invitro drug release profiles and drug release mechanism and optimized. To achieve second objective, optimized AZMC4 were encompassed in bioadhesive gel to form AZMBVGs by cold mechanical...
