Study Evaluating the Effect of Desvenlafaxine on the Pharmacokinetics of Midazolam - Full Text View

Purpose

The main purpose of this study is to evaluate the effect of desvenlafaxine administered as DVS SR on the pharmacokinetics of midazolam in healthy male and female subjects. The amount of drug in the body and the effect of the drug will also be evaluated.

Primary Outcome Measures:

Midazolam Area Under the Plasma Concentration-time Profile From Time 0 Extrapolated to Infinite Time (AUCinf) Following Midazolam Alone and When Coadministered With DVS SR [ Time Frame: Period 1 / Day 1 and Period 2 / Day 6: 0, 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 16, and 24 hours following dosing ] [ Designated as safety issue: No ]
AUCinf measured as nanograms multiplied by hours divided by milliliters (ng*hr/mL).
Midazolam Maximum Observed Plasma Concentration (Cmax) Following Midazolam Alone and When Coadministered With DVS SR [ Time Frame: Period 1 / Day 1 and Period 2 / Day 6: 0, 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 16, and 24 hours following dosing ] [ Designated as safety issue: No ]
Cmax measured as nanograms per milliliters (ng/mL).
1-Hydroxy-Midazolam (Analyte) Area Under the Plasma Concentration-time Profile From Time 0 Extrapolated to Infinite Time (AUCinf) Following Midazolam Alone and When Coadministered With DVS SR [ Time Frame: Period 1 / Day 1 and Period 2 / Day 6: 0, 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 16, and 24 hours following dosing ] [ Designated as safety issue: No ]
1-Hydroxy-Midazolam is an analyte of Midazolam.
1-Hydroxy-Midazolam (Analyte) Maximum Observed Plasma Concentration (Cmax) Following Midazolam Alone and When Coadministered With DVS SR [ Time Frame: Period 1 / Day 1 and Period 2 / Day 6: 0, 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 16, and 24 hours following dosing ] [ Designated as safety issue: No ]
