Brief Summary
To compare and evaluate the bioequivalence study of Methotrexate Tablets 2.5 mg (manufactured for Actavis LLC) with Methotrexate Tablets USP 2.5 mg (DAVA Pharmaceuticals, Inc.,Fort Lee, NJ 07024 USA) in patients with mild to severe psoriasis or rheumatoid arthritis (RA), who are already on established regimens of 2.5 mg every 12 hours under fasting condition. Total expected duration of the study will be of at least 8 days from the day of admission of the first period till the end of study sample collection in period II. There will be at least 7 days duration between the IMP administrations in two study periods. After IMP administration in each period (on day 1), patients will be advised to receive their scheduled dose of 2.5 mg Methotrexate tablet 12 hours apart for additional 2 doses using locally approved drug. A total of 22 PK samples will be collected during each period.
