Overview

Reserpine is a catecholamine-depleting sympatholytic that is FDA approved for the {{{indicationType}}} of mild essential hypertension. Common adverse reactions include abdominal pain, diarrhea, nausea, vomiting, xerostomia, dizziness, headache, lethargy, somnolence, vertigo, depression, and nasal congestion.

Adult Indications and Dosage

FDA-Labeled Indications and Dosage (Adult)

  • Initial Dosage
  • In the average patient not receiving other antihypertensive agents, the usual initial dosage is 0.5 mg daily for 1 or 2 weeks.
  • Maintenance Dosage
  • For maintenance, reduce to 0.1–0.25 mg daily.
  • Higher dosages should be used cautiously, because occurrence of serious mental depression and other side effects may increase considerably.

Mechanism of Action

Structure

  • Reserpine, USP is an antihypertensive, available as 0.1 mg and 0.25 mg tablets for oral administration. Its chemical name is methyl 18β-hydroxy-11,17 α-dimethoxy-3β, 20α-yohimban-16β-carboxylate 3,4,5-trimethoxybenzoate (ester) and its structural formula is:
This image is provided by the National Library of Medicine.
  • Reserpine USP, a pure crystalline alkaloid of rauwolfia, is a white or pale buff to slightly yellowish, odorless crystalline powder. It darkens slowly on exposure to light, but more rapidly when in solution. It is insoluble in water, freely soluble in acetic acid and in chloroform, slightly soluble in benzene, and very slightly soluble in alcohol and in ether. Its molecular weight is 608.69.
  • Inactive Ingredients: Acacia, confectioner’s sugar, corn starch, lactose monohydrate, magnesium stearate.

Pharmacodynamics

  • Reserpine, like other rauwolfia compounds, is characterized by slow onset of action and sustained effects. Both cardiovascular and central nervous system effects may persist for a period of time following withdrawal of the drug.
  • Mean maximum plasma levels of plasma concentrations after a single dose of 0.5 mg of reserpine, administered as two 0.25 mg tablets or as an aqueous solution, peaked after 2.5 hours. The mean peak level was approximately 1.1 ng/ml. The two formulations were found to be bioequivalent. Absolute bioavailability of reserpine, as established by comparison to an intravenous dose, has been reported to be approximately 50%.

Pharmacokinetics

  • Reserpine is extensively bound (95%) to plasma proteins. Reserpine is almost completely metabolized in the body, and only about 1% is excreted as unchanged drug in the urine. No definitive studies on the human metabolism of reserpine have been made. After oral administration, an initial half-life of approximately 5 hours is followed by a terminal half-life of the order of 200 hours. Plasma levels may be measurable 14 days after a single dose. The clinical significance of the long terminal half-life is unknown.
