Chemische Eigenschaften

off-white crystalline powder

Chemische Eigenschaften

Reserpine is a white to pale buff to slightly yellow crystalline substance that darkens on exposure to light.

Verwenden

An indole alkaloid found in Rauwolfia serpentina. Inhibits vesicular uptake of catecholamines and serotonin. Reserpine is reasonably anticipated to be a human carcinogen. Antihypertensive.

Verwenden

An inhibitor of transport of biogenic amines into adrenal chromaffin granules

Verwenden

Reserpine occurs in the roots of Rauwolfiaserpentina and other Rauwolfia species, suchas R. micrantha, R. canescens, and R. vomitoria Hook. It is used therapeutically as anantihypertensive agent and a tranquilizer. Itsuse has been reduced significantly because oftoxic side effects.

Definition

ChEBI: An alkaloid found in the roots of Rauwolfia serpentina and R. vomitoria.

Trademarks

Rau-Sed (Bristol-Myers Squibb); Sandril (Lilly); Serpasil (Novartis).

Biologische Funktion

Reserpine (Serpasil) is the prototypical drug interfering with norepinephrine storage. Reserpine lowers blood pressure by reducing norepinephrine concentrations in the noradrenergic nerves in such a way that less norepinephrine is released during neuron activation. Reserpine does not interfere with the release process per se as does guanethidine.
Reserpine also interferes with the neuronal storage of a variety of central transmitter amines such that significant depletion of norepinephrine, dopamine, and 5- hydroxytryptamine (serotonin) occurs. This central transmitter depletion is responsible for the sedation and other CNS side effects associated with reserpine therapy. The depletion of brain amines also may contribute to the antihypertensive effects of reserpine.

Allgemeine Beschreibung

Reserpine (Serpasil, Reserpoid, Rau-Sed, Sandril) is a white to light yellow, crystalline alkaloid,practically insoluble in water, obtained from various speciesof Rauwolfia. In common with other compounds with anindole nucleus, it is susceptible to decomposition by lightand oxidation, especially when in solution. In the dry state,discoloration occurs rapidly when reserpine is exposed tolight, but the loss in potency is usually small. In solution,reserpine may break down with no appreciable color changewhen exposed to light, especially in clear glass containers;thus, color change cannot be used as an index of the amountof decomposition.

Allgemeine Beschreibung

Reserpine, a prototypicaland historically important drug, is an indole alkaloid obtainedfrom the root of Rauwolfia serpentina found in India.As is typical of many indole alkaloids, reserpine is susceptibleto decomposition by light and oxidation. Reserpine isextensively metabolized through hydrolysis of the esterfunction at position and yields methyl reserpate and3,4,5-trimethoxybenzoic acid. It not only depletes the vesiclestorage of NE in sympathetic neurons in PNS, neuronsof the CNS, and E in the adrenal medulla, but also depletesthe storage of serotonin and DA in their respective neuronsin the brain. Reserpine binds extremely tightly with andblocks VMAT that transports NE and other biogenic aminesfrom the cytoplasm into the storage vesicles. Thus in sympatheticneurons, NE, which normally is transported into thestorage vesicles, is instead metabolized by mitochondrialMAO in the cytoplasm. In addition, there is a gradual loss ofvesicle-stored NE as it is used up by release resulting fromsympathetic nerve activity so that the storage vesicles eventuallybecome dysfunctional. The end result is a depletion ofNE in the sympathetic neuron. Analogous effects are seen inthe adrenal medulla with E and with 5-HT in serotonergicneurons.

Allgemeine Beschreibung

White or cream to slightly yellow crystals or crystalline powder. Odorless with a bitter taste.

Air & Water Reaktionen

Insoluble in water. Reacts slowly with air and water. Darkens slowly on exposure to light.

Reaktivität anzeigen

Reserpine is a weak base and can form salts with strong acids. Incompatible with oxidizing agents and reducing agents.

Hazard

Questionable carcinogen.

Health Hazard

Reserpine produces sedative, hypotensive,
LD50 value, intraperitoneal (mice): 5 mg/kg
LD50 value, oral (mice): 200 mg/kgand tranquilizing effects. This is due to itsactions of causing depletion of monoaminesfrom presynaptic nerve terminals in central and peripheral nervous systems. Theadverse side effects are drowsiness, nightmare, depression, excessive salivation, nausea, diarrhea, increased gastric secretion,abdominal cramps, and hypotension.

Brandgefahr

Flash point data for Reserpine are not available; however, Reserpine is probably combustible.

Biologische Aktivität

Binds the vesicular monoamine transporter (VMAT2) and inhibits transport of biogenic amines into adrenal chromaffin granules and synaptic vesicles. Causes depletion of biogenic amine stores. Antihypertensive and antipsychotic.

Clinical Use

Reserpine is effective orally and parenterally for thetreatment of hypertension. After a single intravenous dose,the onset of antihypertensive action usually begins in about1 hour. After intramuscular injection, the maximumeffect occurs within approximately 4 hours and lasts about10 hours. When it is given orally, the maximum effectoccurs within about 2 weeks and may persist up to 4 weeksafter the final dose. When used in conjunction with otherhypotensive drugs in the treatment of severe hypertension,the daily dose varies from 100 to 250μg.

Clinical Use

When reserpine is given orally, its maximum effect is seenafter a couple of weeks. A sustained effect up to severalweeks is seen after the last dose has been given. This isbecause the tight binding of reserpine to storage vesicles continuesfor a prolonged time, and recovery of sympatheticfunction requires synthesis of new vesicles over a period ofdays to weeks after discontinuation of the drug. Most adverseeffects of reserpine (log P=4.37) are caused by CNS effectsbecause it readily enters the CNS. Sedation and inability toconcentrate or perform complex tasks are the most commonadverse effects. More serious is the occasional psychoticdepression that can lead to suicide, which support monoaminetheory of pathology of depression. Agents with fewer sideeffects have largely replaced reserpine in clinical use.

Nebenwirkungen

The most troublesome untoward effects of treatment with reserpine involve the CNS. Sedation and depression are the most common, although nightmares and thoughts of suicide also occur. Reserpine treatment, therefore, is contraindicated in patients with a history of severe depression. The occasional report of reserpine- induced extrapyramidal symptoms, which are similar to those seen in patients with Parkinson’ s disease, is believed to be a result of dopamine depletion from neurons in the CNS.
Peripheral nervous system side effects are the result of a reserpine-induced reduction of sympathetic function and unopposed parasympathetic activity; symptoms include nasal congestion, postural hypotension, diarrhea, bradycardia, increased gastric secretion, and occasionally impotence. Because of the increased gastric secretion, reserpine is contraindicated for patients with peptic ulcer. In patients with little cardiac reserve, reserpine must be administered with caution because of its ability to interfere with sympathetic stimulation of the heart.

Sicherheitsprofil

Confirmed human carcinogen producing tumors of the sh and brain. Poison by ingestion, intravenous, subcutaneous, and intraperitoneal routes. Mutation data reported. An experimental teratogen. Human and experimental reproductive effects by ingestion: sullbirth, reduced viability, and other neonatal measures or effects. In humans, 0.014 mg/kg causes psychotropic effects. A medicine with side effects. Used as an addltive permitted in the feed and drinking water of animals and/or for the treatment of food-producing animals. Also permitted in food for human consumption. A sedative. When heated to decomposition it emits toxic fumes of NOx.

mögliche Exposition

Reserpine, a pharmaceutical, is a natu- rally occurring substance that is isolated from the roots of the plant rauwolfia serpentina. Insoluble in water. Reserpine is used as a hypertensive for humans and ani- mals; tranquilizer, and sedative. Permitted for use as an additive in food for human consumption, and the feed and drinking water of food-producing animals.

Carcinogenicity

Reserpine is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
