Summary

The purpose of this study is to determine if two formulations of diphenhydramine hydrochloride are bioequivalent.

Clinical Details

Official title: A Randomized, Two-Way Crossover Evaluation of the Bioequivalence Between Two Oral Formulations of Diphenhydramine: ULTRATAB Tablet Versus KAPSEALS Capsule

Study design: Allocation: Randomized, Endpoint Classification: Bio-equivalence Study, Intervention Model: Crossover Assignment, Masking: Open Label, Primary Purpose: Basic Science

Primary outcome: Bioequivalence was assessed based on the pharmacokinetic variables, Cmax, AUC0-t and AUC0-infinity

Secondary outcome: The safety analysis included all subjects who took at least one dose of clinical trial test product and had any follow-up information. Subjects in the safety analysis set were summarized and listed, based on actual treatment received.

Detailed description: Subjects were required to observe a ten-hour fast and a one-hour fluid restriction prior to each dosing period. Subjects were randomized into one of two active treatment groups, received supervised dosing of their treatment with approximately eight ounces of water, and were required to maintain fluid restriction for one hour after treatment. Following the one-hour post-dose fluid restriction, subjects could drink water, but consumer no other food or fluids for four hours post-dose. Following a seven-day washout period, the comparison treatment was administered according to the same procedure as above.
