Bioequivalence, diphenhydramine hydrochloride

Outcome Measures

Primary Outcomes (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 Outcomes (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

Study Arms (1)

1

EXPERIMENTAL

Diphenydramine HCl

Drug: Diphenhydramine hydrochloride

Interventions

After a ten-hour fast and a one-hour fluid restriction prior to each dosing period, subjects received supervised dosing of their first 25 mg treatment with approximately eight ounces of water. Following a seven-day washout, the comparison treatment was administered according to thye same procedure.
