Study Summary

The purpose of this study is to find out if the anti-HIV drugs nelfinavir (NFV), lopinavir/ritonavir (LPV/r), and efavirenz (EFV) change the amount of estrogen in the blood when taken along with hormone replacement therapy (HRT) for menopause. HRT can be helpful for treating bothersome symptoms of menopause. However, it is not routinely used in HIV-infected postmenopausal women because it is not known how HRT interacts with anti-HIV drugs. The information obtained from this study will help doctors make recommendations for HRT in postmenopausal HIV-infected women.
