Drug Type: Ropinirole Hydrochloride is a non-ergoline dopamine agonist that acts specifically at D2 and D3 dopamine receptors.
Mechanism of Action: 1. Dopamine Agonism: Ropinirole Hydrochloride works primarily by stimulating dopamine receptors in the brain. It mimics the effects of dopamine, a naturally occurring neurotransmitter, which is deficient in patients with Parkinson's disease. 2. Parkinson's Disease: By activating D2 and D3 receptors, ropinirole improves motor function and reduces symptoms such as tremor, rigidity, and bradykinesia (slowness of movement). 3. Restless Legs Syndrome (RLS): Ropinirole is also effective in managing symptoms of RLS, a condition characterized by an uncontrollable urge to move the legs.
