Official title
A Phase I Pharmacokinetic Study of Once Versus Twice Daily Dosing With Zidovudine and Lamivudine
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to see if the full daily dose of Combivir (zidovudine \[ZDV\]/lamivudine \[3TC\]) taken once a day is as effective as the usual recommended twice-a-day dose. Studies have shown that the antiviral activity of ZDV can continue in the body even after there does not appear to be any ZDV left in the blood. This occurs because the body breaks down the drug into substances that remain active against HIV. The body also breaks down 3TC, a drug that is combined with ZDV in the Combivir product, in a similar way. Since antiviral activity may continue after Combivir is removed from the body, it may not be necessary to take the drug as often as once thought. This study carefully measures levels of the active substances in order to find out whether the same amount of antiviral activity occurs with less-frequent dosing.
