I know that haloperidol is a drug that blocks dopamine synapses, but how can it be used then for patients with mental illness.
The precise mechanism of action of haloperidol has not been clearly established.
It blocks dopamine receptors in the CNS.
Haloperidol is contraindicated in patients with Parkinson's disease. The dopamine blockade from haloperidol will dramatically worsen the preexisting Parkinson's disease, possibly incapacitating the patient.
