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.

Exclusion criteria
* If female, pregnant, lactating or likely to become pregnant during this study. * History of allergy or sensitivity to ropinirole or other dopamine agonists (e.g. Corolpam®, Dostinex®, Mirapex®, Permax®, Symmetrel®) or history of any drug hypersensitivity of intolerance which, in the opinion of the Investigator, would compromise the safety of the subject or the study. * History of dizziness, lightheadedness or fainting upon standing. * Significant history or current evidence of chronic infectious disease, system disorders, organ dysfunction, hyper/hypotension, arrythmia, tachycardia, seizure disorder or glaucoma. * Presence of gastrointestinal disease or history of malabsorption within the last year. * History of psychiatric disorders occuring within the last two years that required hospitalization or medication. * Presence of a medical condition requiring regular treatment with prescription drugs. * Use of pharmacologic agents known to significantly induce or inhibit drug-metabolizing enzymes within 30 days prior to dosing. * Receipt of any drug as part of a research study within 30 days prior to dosing. * Drug or alcohol addiction requiring treatment in the past 12 months. * Donation or significant loss of whole blood (480 ml or more) within 30 days or plasma within the past 14 days prior to dosing. * Positive test results for HIV, Hepatitis B surface antigen or Hepatitis C antibody. * Positive test results for drugs of abuse at screening. * Tobacco user within 90 days of the first study date. * Unable, or unwilling to tolerate multiple venipunctures. * Difficulty fasting or eating the standard meals that will be provided.
