Ropinirole is a generic prescription drug that mimics dopamine in the brain. It’s a common treatment for Parkinson’s disease and restless legs syndrome (RLS), both of which are caused by abnormally low dopamine levels. Available only in tablet form, ropinirole can be taken three times daily as an immediate-release tablet or once daily in its extended-release dosage form. People being treated for RLS will take one immediate-release tablet daily before bedtime.
