Sustiva Levels With Use of a Gel Capsule

Brief Summary:
We are studying if putting a gel capsule over a standard HIV drug changes the ability of the body to absorb the drug. This is important because we want to be able to study new HIV drugs against the most common drugs used today and the most common is Sustiva, which is also called efavirenz. We will give you Sustiva every day for 5 days and draw blood to see how much is absorbed. Then we will give you Sustiva that has a gel capsule over it for 5 days and we will draw blood to see how much is absorbed.

Subject will take efavirenz for 5 days.
Other Name: Sustiva

Experimental: over-encapsulated efavirenz Drug: Over-encapsulated efavirenz
Subject will take efavirenz that has been over-encapsulated with a gel capsule for 5 days.
Other Name: Over-encapsulated Sustiva

Primary Outcome Measures :
  1. Serum Levels of Efavirenz [ Time Frame: 5th day of taking drug ]
    Serum levels of efavirenz were measured on the fifth day of taking efavirenz (tablet) and the fifth day of taking an overencapsulated efavirenz.
