Dopamine stimulators are drugs that mimic the effect of the neurotransmitter dopamine in the body. They are chiefly used to treat symptoms related to Parkinson’s disease. This illness interferes with the production of dopamine, which regulates movement in the body.

Dopamine stimulators mimic the role of dopamine in the brain by causing neurons to react as though there is a sufficient amount of dopamine present in the body. In effect, they trick the brain into thinking it is receiving dopamine. This helps relieve symptoms and delays the onset of motor complications.

Various side effects are associated with use of dopamine stimulators. People who take these medications in combination with the dopamine precursor levodopa often experience drowsiness. In some cases, this is severe enough to induce sudden sleep. Some patients who take dopamine stimulators also may find themselves more likely to engage in compulsive behaviors. Symptoms of overdose can be similar to the medication’s side effects, but are usually more severe.

Certain health conditions may preclude the use of dopamine stimulators by some patients. These drugs may not be suitable for people with certain illnesses, including a history of certain heart or psychological conditions. In addition, dosage levels of dopamine stimulators may have to be adjusted for patients with kidney or liver problems. Recently there have also been reports linking certain dopamine stimulators with heart valve defects.

Certain drugs may interact poorly with dopamine stimulators. As a result, patients are urged to tell their physician if they are taking any medications, including antidepressants, antihypertensives or sedatives.
