Brief summary

The purpose of this study is to support the submission of Advil PM Liqui-Gels Minis (ibuprofen/diphenhydramine hydrochloride 200 milligrams \[mg\]/25 mg) which is a size reduction of the currently marketed Advil PM Liqui-Gels, by determining if this product is bioequivalent to the reference product Advil PM Liqui-Gels (ibuprofen/diphenhydramine hydrochloride 200 mg/25 mg) under fasting conditions.

Detailed description

This is a single center, single dose, open-label, randomized, two-treatment, two-sequence, two-period crossover, bioequivalence study in healthy adult participants with at least a 7-day washout period. A sufficient number of participants will be screened to randomize approximately 44 to ensure at least 37 evaluable participants complete the entire study. Participants will be randomly assigned to one of 2 treatment sequences and receive a single dose of one of the treatments in each period following a crossover design.

Area Under the Plasma Concentration Versus Time Curve Calculated From Time 0 to Infinity (AUC [0-inf]) for Ibuprofen

AUC (0-inf) was defined as area under the plasma concentration versus time curve calculated from time 0 to infinity, computed as AUC0-inf = AUC0-t + C(last)/λz where C(last) was the concentration at the last measurable sampling time point and λz was the terminal elimination rate constant. Blood samples were collected at indicated timepoints and PK analysis was performed. Geometric coefficient of variation was not calculated and the arithmetic coefficient of variation (CV%) is being reported.

Number of Participants Reporting Ease of Swallowing on 5-Point Ordinal Scale

Immediately after dosing, the assessment of 'ease of swallowing' was done via one question with an ordinal response (ease of swallowing on 5-point ordinal scale) of each product. Participants ranked the 'ease of swallowing' of the product on a scale from 1 to 5 where 1=not easy to swallow; 2=somewhat easy to swallow; 3=average to swallow; 4=above average to swallow; 5=very easy to swallow. Higher score indicated more ease in swallowing.
