The purpose of this study is to look at the safety and effectiveness of receiving lamivudine (3TC) once a day versus twice a day as part of an anti-HIV drug combination.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients are randomized to receive the same total dosage of 3TC either twice a day (Group 1) or once a day (Group 2) in combination with ZDV and EFV over 48 weeks. Viral load measurements will be performed at Weeks 4, 8, 12, 16, 20, 24, and every 8 weeks thereafter.
