Bioequivalence of Alprazolam Sublingual vs Oral Tablets

January 26, 2021 updated by: Pfizer's Upjohn has merged with Mylan to form Viatris Inc.

Open-Label, Randomized, Single-Dose, 2-Way Crossover Pivotal Bioequivalence Study Comparing Alprazolam Immediate Release (IR) Tablets (Administered Orally) And Alprazolam Sublingual (SL) Tablets (Administered Sublingually)

This study tests the assumption that the bioavailability of alprazolam from a new sublingual formulation is the same as that from a standard orally administered tablet.
