Study Endpoints
Primary Endpoints
Area under the plasma concentration-time curve from zero hours to last quantifiable time (AUC0-t)
Pre-dose and 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 6.0, 7.0, 8.0, 10.0, 12.0, 16.0, 24.0, 36.0, 48.0, 60.0, 72.0 and 96.0 hours post dose in each treatment period

Bioequivalence will be evaluated for isotretinoin 40 mg using three distinct medications; two assigned as reference medication (T1 and T2) and 1 test medication (T3). Each subject will receive 2 capsules (20 mg each) orally.

Area under the plasma concentration-time curve from zero hours to infinite (AUC0-infinity)
Pre-dose and 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 6.0, 7.0, 8.0, 10.0, 12.0, 16.0, 24.0, 36.0, 48.0, 60.0, 72.0 and 96.0 hours post dose in each treatment period

Bioequivalence will be evaluated for isotretinoin 40 mg using three distinct medications; two assigned as reference medication (T1 and T2) and 1 test medication (T3). Each subject will receive 2 capsules (20 mg each) orally.

Maximum drug concentration (Cmax)
Pre-dose and 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 6.0, 7.0, 8.0, 10.0, 12.0, 16.0, 24.0, 36.0, 48.0, 60.0, 72.0 and 96.0 hours post dose in each treatment period

Bioequivalence will be evaluated for isotretinoin 40 mg using three distinct medications; two assigned as reference medication (T1 and T2) and 1 test medication (T3). Each subject will receive 2 capsules (20 mg each) orally.

Time to maximum drug concentration (Tmax)
Pre-dose and 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 6.0, 7.0, 8.0, 10.0, 12.0, 16.0, 24.0, 36.0, 48.0, 60.0, 72.0 and 96.0 hours post dose in each treatment period

Isotretinoin ArmEXPERIMENTALAll subjects in this study will be randomized to receive all the 3 distinct medications of isotretinoin in a sequential manner. Subjects will receive a single dosage of two capsules x 20 mg (40 mg) orally, for three periods, six sequences, with a wash-out period of two weeks to eliminate the first dosage.
