Dopamine agonists are medications that mimic the action of dopamine, a neurotransmitter in the brain that plays a key role in movement, mood, and reward. These drugs bind to dopamine receptors, stimulating them and helping to alleviate symptoms associated with conditions like Parkinson's disease and restless legs syndrome. By activating dopamine receptors, dopamine agonists can improve motor function and reduce the need for other medications. Common examples include pramipexole and ropinirole. While effective, they may also have side effects, such as nausea, dizziness, or compulsive behaviors, which should be monitored by healthcare providers.
