Reserpine: The Antihypertensive and Antipsychotic Medication
What is Reserpine?
Reserpine is an antihypertensive and antipsychotic medication. It is primarily used to treat high blood pressure (hypertension) and is sometimes used for schizophrenia. Reserpine works by depleting dopamine, serotonin, and norepinephrine in the brain, which helps to control blood pressure and treat psychotic symptoms.
How Reserpine Works
Reserpine works by blocking the uptake of monoamines into synaptic vesicles, reducing the release of dopamine, serotonin, and norepinephrine.By depleting these biogenic amines, Reserpine lowers the blood pressure by relaxing blood vessels and reducing heart rate.
