A Study to Evaluate the Effects of Different Methods of Birth Control on the Drug Actions of Zidovudine (an Anti-HIV Drug) in HIV-Positive Women and to Compare Zidovudine Metabolism in Men and Women

Completed · Not applicable

Conditions studied: HIV Infections

In brief

The purpose of this study is to look at the effects of different methods of birth control (oral and injectable) on how the body absorbs, makes available, and removes zidovudine (ZDV). This study will also evaluate the differences in men and women in how the body absorbs, makes available, and removes ZDV. Past research has shown that the effectiveness of ZDV as an anti-HIV drug might be decreased in individuals who use certain methods of birth control. ZDV may also have different effects in men compared to women.
