Study 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).

Primary Outcome

The primary outcome measure will be atazanavir area-under-the-concentration curve (AUC) values from zero-to-twenty two (0-22) hours. Values from Experimental Arms of the study (Ritonavir-boosted Atazanavir plus Rabeprazole; Ritonavir-boosted Atazanavir plus Rabeprazole AND Betaine Hydrochloride) will be compared against the active comparator (Ritonavir-boosted atazanavir alone) and tested for statistical significance.

Interventions

  • DRUG Ritonavir-boosted Atazanavir
  • DRUG Ritonavir-boosted Atazanavir plus Rabeprazole
  • DRUG Ritonavir-boosted Atazanavir plus Rabeprazole AND Betaine Hydrochloride
