Ropinirole 0.25 mg Tablets Under Fasting Conditions

Study Overview
=================
Brief Summary
-----------------
The objective of this study was to compare the relative bioavailability of the test formulation of Ropinirole (TEVA Pharmaceuticals USA) with already marketed reference of Requip® (Manufactured by SmithKline Beecham Pharmaceuticals for GlaxoSmithKline) under fasting conditions in healthy, non-smoking, adult subjects.
