Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To evaluate the potential pharmacokinetic interaction between nevirapine and clarithromycin, and to determine the effects of nevirapine on cytochrome P450 3A4 (CYP3A4) activity in vivo.

Detailed Description

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

The study is conducted in two separate groups. Patients in Group I receive clarithromycin orally for 32 days and nevirapine orally for 28 days.

Patients in Group II receive erythromycin intravenously on days 0, 14, 28, and 43 and nevirapine orally for 28 days.
