RESERPINE - Watsons Health

RESERPINE

COMMON BRAND NAME(S): Serpasil

GENERIC NAME(S): RESERPINE

 

Description: Reserpine is a rauwolfia alkaloid that works by decreasing the amount of several chemicals (norepinephrine and serotonin) in the brain.  This drug helps to lower blood pressure and decrease agitation in patients who have certain mental problems.

Pharmacokinetics:

Absorption: Readily absorbed from the GI tract, bioavailability: about 50%.

Distribution: Crosses the blood brain barrier and appears in breast milk. 95% bound to plasma proteins.

Metabolism: Extensive metabolism.

Excretion: About 8% is excreted in urine as metabolites and about 60% is excreted in faeces, mainly unchanged.

Reserpine is used with or without other medications to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. It works by decreasing certain substances in the body (such as norepinephrine). This causes the blood vessels to relax so that blood can flow more easily and also slows the heart rate. These effects help to lower blood pressure.

How to use reserpine

Take this medication by mouth with or without food, usually 1 to 2 times daily or as directed by your doctor.
