Levels of Raltegravir in the Female Genital Tissue

Summary

This study is an investigation of the pharmacokinetics of raltegravir in the tissue of the female genital tract to determine if twice-daily dosing of 400mg achieves adequate drug levels to prevent viral integration of HIV-1. The study will also assess whether drug levels change in the tissue across the different phases of the menstrual cycle. * Hypothesis #1: Twice daily dosing with raltegravir 400mg will result in intracellular concentrations that should be sufficient to suppress HIV-1 replication throughout the menstrual cycle. * Hypothesis #2: Intracellular genital raltegravir peaks will be lower and troughs higher compared to extracellular concentrations in the plasma and PMBCs (peripheral blood mononuclear cells). * Hypothesis #3: Intracellular raltegravir concentrations will be slightly lower during the luteal phase of the menstrual cycle due to cellular pumps such as p-glycoprotein, which are present in higher numbers during periods of high progesterone.
