Bioequivalence Study of Aripiprazole in Healthy Adult Subjects Under Fasting Condition


Future University in Egypt

Status and phase

Phase 1


Healthy Subjects


Drug: Aripiprazole 10 mg tablet
Drug: Abilify® 10 mg tablet

Study type


Funder types




Details and patient eligibility


To evaluate and compare the relative plasma bioavailability and therefore the bioequivalence of two different immediate release products each containing Aripiprazole 10 mg, after administering a single oral dose, to healthy adult subjects under fasting conditions.

Full description

Enrolled subjects were randomized in a two-phase, two-sequence, cross-over design to receive a single dose of the test product (T) or the reference product (R) at each phase, under fasting conditions, with a wash-out period of 21 days. Aripiprazole plasma concentration was determined using a validated LC-MS-MS method, followed by Pharmacokinetics, and statistical analysis using Phoenix WinNonlin® software to determine the average bioequivalence.
