In Parkinson disease, monotherapy use early in the course delays the need for levodopa; adjunct use later in the course extends "on" time and allows levodopa dose reduction. The D3-preference is the proposed mechanism for the off-label efficacy in bipolar depression and treatment-resistant depression.</vote> '''Impulse control disorders''' (pathological gambling, hypersexuality, compulsive shopping, binge eating) are a recognized class effect of dopamine agonists with substantially higher incidence than with levodopa. Other major adverse effects include somnolence with sleep attacks (potentially while driving), hallucinations, peripheral edema, and dyskinesias. Renally eliminated; dose adjustment required in renal impairment<ref name="mirapex-label" />. | ||
