Detailed Description:

Randomized, single-dose, two-treatment, two-way, crossover study was conducted to compare the relative bioavailability of two risperidone 1 mg tablet formulations under Fed conditions.

The study was conducted with 26 healthy adults. In each study period, a single 1 mg dose was administered to the subjects following a standardized high-fat breakfast preceded by an overnight fast of at least 10 hours.

The subjects received the test product in one study period and the reference product in the other period; the order of administration was according to the dosing randomization schedule. There was a 7-day interval between treatments.
