Comparative Bioavailability Study of Aripiprazole 10 mg Oral Soluble Film vs Abilify® 10 mg Tablet in Healthy Volunteers

The proposed study is a single centre, bioavailability, open-label, randomized, single-dose, 3-period, 6-sequence, crossover study under fasting conditions. Each volunteer will be given a single dose of the Test formulation in two study periods (with and without water), and a single dose of the Reference formulation (with water) in the other study period.
