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.
Official title: 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)
Study design: Allocation: Randomized, Endpoint Classification: Pharmacokinetics Study, Intervention Model: Crossover Assignment, Masking: Open Label, Primary Purpose: Basic Science
Primary outcome: Alprazolam bioavailability assessed as area under the concentration-time curve (AUC) and maximum concentration (Cmax)
Alprazolam time of maximum concentration (Tmax) and half life
