Study Details

Study Description

Brief Summary

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

Condition or Disease Intervention/Treatment Phase
  • Drug: Diphenhydramine hydrochloride
Phase 1

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.

Arms and Interventions

Arm Intervention/Treatment
Experimental: 1

Diphenydramine HCl

Drug: Diphenhydramine hydrochloride

Other Names:
  • Benadryl Allergy
  • 25 mg KAPSEALS capsule
  • 25 mg ULTRATAB tablets
  • Outcome Measures

    Primary Outcome Measures

    1. Bioequivalence was assessed based on the pharmacokinetic variables, Cmax, AUC0-t and AUC0-infinity [At 15 minutes pre-dose (0 hour), and at 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 14, 16, 24, 36 and 48 hours post-dose]

    Secondary Outcome Measures

    1. 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. [15 minutes pre-dose (0 hour) through 28 days post-dose]
