Further study details as provided by Johnson & Johnson Consumer & Personal Products Worldwide:

Primary Outcome Measures:

Bioequivalence was assessed based on the pharmacokinetic variables, Cmax, AUC0-t and AUC0-infinity [ Time Frame: 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 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

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. [ Time Frame: 15 minutes pre-dose (0 hour) through 28 days post-dose ] [ Designated as safety issue: No ]

Enrollment:	36
Study Start Date:	October 2006
Study Completion Date:	November 2006
Primary Completion Date:	November 2006 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
1: Experimental Diphenydramine HCl	Drug: Diphenhydramine hydrochloride 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.

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.
