Brief Summary:
The purpose of the study is to look at the levels of three HIV medications: tenofovir, emtricitabine, and efavirenz in blood after the drug intake has been stopped in order to understand how long these drugs persist in the blood. The study will specifically look at blood levels of these three drugs (taken as a 3-in-1 tablet) after taking them every day for 14 days.
This study is not randomised which means that all subjects will receive all study medications in the same order. You and the study doctor will know which study medications you are taking at all times during the study.

Primary Outcome Measures
:
- pharmacokinetics of plasma tenofovir, emtricitabine and efavirenz [ Time Frame: 24 days ]To assess the pharmacokinetics of plasma tenofovir and emtricitabine, and their active intracellular anabolites, tenofovir-diphosphate and emtricitabine-triphosphate, and plasma efavirenz over 10 days following drug intake cessation, in HIV negative healthy volunteers
Secondary Outcome Measures
:
- inter subject variability [ Time Frame: 24 days ]To assess the inter subject variability in the concentrations of plasma tenofovir and emtricitabine, and their active intracellular anabolites, and plasma efavirenz following drug intake cessation
- safety and tolerability of Atripla® [ Time Frame: 24 days ]To assess the safety and tolerability of Atripla® over 14 days of administration in HIV negative healthy volunteers
- pharmacogenetic [ Time Frame: 24 days ]To investigate the association between genetic polymorphisms in drug disposition genes and drug exposure

Exclusion Criteria:
Subjects who meet any of the following exclusion criteria are not to be enrolled in this study.
- Any significant acute or chronic medical illness
- Evidence of organ dysfunction or any clinically significant deviation from normal in physical examination, vital signs, ECG or clinical laboratory determinations
- Positive blood screen for hepatitis B surface antigen and/or C antibodies
