HIDE SMILES / InChI
Reserpine is an alkaloid, isolated from the Rauwolfia serpentina plant and developed by Ciba pharma. Reserpine was approved by FDA for the treatment of hypertension and psychotic disorders. The drug exerts its effect by blocking two vesicular monoamine transporters, VMAT1 and VMAT2. The blockade results in vesicles that lose their ability to store neurotransmitter molecules. Neurotransmitters, thus retained in cytosol, are then neutralized by MAO.

Originator

Curator's Comment: Later Ciba-Geigy and now Novartis.

Sample Use Guides

Hypertension: In the average patient not receiving other antihypertensive agents, the usual initial dosage is 0.5 mg daily for 1 or 2 weeks. For maintenance, reduce to 0.1-0.25 mg daily. Psychiatric Disorders: the usual initial dosage is 0.5 mg daily, but may range from 0.1 mg to 1.0 mg. Adjust dosage upward or downward according to the patient's response.
Route of Administration: Oral
