Drug : Erythromycin
Drug : Nevirapine
Drug : Clarithromycin
Phase 1

Study Design: Intervention Model: Parallel Assignment
Primary Purpose: Treatment
Official Title: An Open-Label Study in HIV+ Patients to Determine the Effects of Nevirapine (Viramune) on the Pharmacokinetics of Clarithromycin and Activity of Cytochrome 3A4.

Further study details as provided by NIH AIDS Clinical Trials Information Service:

Enrollment: 36

Detailed Description:

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.
