Effects of Gastric pH on the Pharmacokinetics of Atazanavir
NCT01759875 · Status: COMPLETED · Phase: PHASE1 · Type: INTERVENTIONAL · Enrollment: 8
Last updated 2015-04-28
Summary
The goal of this study is to evaluate the ability of a natural supplement (betaine hydrochloride) to affect the absorption of atazanavir in healthy volunteers. The investigators predict that betaine hydrochloride will increase the absorption of atazanavir in volunteers pre-treated with proton-pump inhibitors (PPIs).
