VMAT2 is mostly expressed in neurons. Thus, it is the blockade of neuronal VMAT2 by reserpine that inhibits uptake and reduces stores of the monoamine neurotransmitters norepinephrine, dopamine, serotonin and histamine in the synaptic vesicles of neurons.

What is the name of the alkaloids in the plant reserpine?

Reserpine is one of dozens of indole alkaloids isolated from the plant Rauvolfia serpentina. In the Rauvolfia plant, tryptophan is the starting material in the biosynthetic pathway of reserpine, and is converted to tryptamine by tryptophan decarboxylase enzyme. Tryptamine is combined with secologanin in the presence of strictosidine synthetase enzyme and yields strictosidine. Various enzymatic conversion reactions lead to the synthesis of reserpine from strictosidine.

Absolute bioavailability of Reserpine, as established by comparison to an intravenous dose, has been reported to be approximately 50%. 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.

What is the effect of reserpine on the brain?

Reserpine depletes stores of catecholamines and 5-hydroxytryptamine in many organs, including the brain and adrenal medulla. Most of its pharmacological effects have been attributed to this action. Depletion is slower and less complete in the adrenal medulla than in other tissues. The depression of sympathetic nerve function results in a decreased heart rate and a lowering of arterial blood pressure. The sedative and tranquilizing properties of Reserpine are thought to be related to depletion of catecholamines and 5-hydroxytryptamine from the brain.

What is the UV maxima of reserpine?

In a chloroform solvent, reserpine has three UV maxima at 216 nm, 267 nm, and 295 nm, which may suggest a potential for direct photolysis in the environment. Occupational exposure to reserpine may occur through dermal contact with this compound at workplaces where reserpine is produced or used.

What is reserpine used for?

Reserpine's production and use as an antihypertensive, central depressant, and sedative drug for both humans and animals may result in its release to the environment through various waste streams. Reserpine is a naturally occurring alkaloid produced by several members of the genus Rauwolfia; which is a climbing shrub of the Apocynaceae family, indigenous to India, Burma, Malaysia, Thailand, Nepal and Indonesia. If released to air, an estimated vapor pressure of 4.5X10-16 mm Hg at 25 °C indicates reserpine will exist solely in the particulate phase in the ambient atmosphere. Particulate-phase reserpine will be removed from the atmosphere by wet and dry deposition. If released to soil, reserpine is expected to be immobile based upon an estimated Koc of 2.70X10+6. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 5.4X10-23 atm-cu m/mole. The pKb of reserpine is 6.6, indicating that this compound will exist partially in the protonated form in the environment and cations generally adsorb to organic carbon and clay more strongly than their neutral counterparts. Volatilization from moist soil surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. Reserpine is not expected to volatilize from dry soil surfaces based upon its vapor pressure. If released into water, reserpine is expected to adsorb to suspended solids and sediment in water based upon the estimated Koc. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. A pKb of 6.6 indicates reserpine will exist partially in the ionized form at pH values of 5 to 9. An estimated BCF of 72 suggests the potential for bioconcentration in aquatic organisms is moderate. A hydrolysis half-life was reported to be 1.7 yrs at pH 7 and 25 °C. In a chloroform solvent, reserpine has three UV maxima at 216 nm, 267 nm, and 295 nm, which may suggest a potential for direct photolysis in the environment. Occupational exposure to reserpine may occur through dermal contact with this compound at workplaces where reserpine is produced or used. (SRC)

What is a U200?

U200; As stipulated in 40 CFR 261.33, when reserpine, as a commercial chemical product or manufacturing chemical intermediate or an off-specification commercial chemical product or a manufacturing chemical intermediate, becomes a waste, it must be managed according to Federal and/or State hazardous waste regulations. Also defined as a hazardous waste is any residue, contaminated soil, water, or other debris resulting from the cleanup of a spill, into water or on dry land, of this waste. Generators of small quantities of this waste may qualify for partial exclusion from hazardous waste regulations (40 CFR 261.5).

What is the mechanism of action of reserpine?

Reserpine's mechanism of action is through inhibition of the ATP /Mg 2+ pump responsible for the sequestering of neurotransmitters into storage vesicles located in the presynaptic neuron. The neurotransmitters that are not sequestered in the storage vesicle are readily metabolized by monoamine oxidase (MAO) causing a reduction in catecholamines.

How much reserpine is toxic to dogs?

In dogs, when given orally, a single dose of 10 mg/kg is fatal.

What is the purpose of reserpine?

Reserpine is an adrenergic blocking agent used to treat mild to moderate hypertension via the disruption of norepinephrine vesicular storage . The antihypertensive actions of Reserpine are a result of its ability to deplete catecholamines from peripheral sympathetic nerve endings. These substances are normally involved in controlling heart rate, force of cardiac contraction and peripheral resistance.

How long does it take for reserpine to resolve?

A mild leukocytosis resolved within 2 weeks. Three cases of reserpine ingestion in children between 30 months and 4 years of age, who ingested large doses of reserpine (2 cases), and an unknown dose (1 case), demonstrated a wide range of toxicity. All cases had some lethargy and CNS depression which progressed to coma.

What is reserpine used for?

Reserpine has FDA approval since 1955 and is one of the first agents developed to treat hypertension in clinical practice . Reserpine can be prescribed alone or combined with a vasodilator or thiazide diuretic, such as reserpine-hydrochlorothiazide, as commonly used in China for over 40 years. [1][2] Reserpine was utilized as a first-line antihypertensive therapy when initially introduced but is currently considered second-line treatment.[3]  This change in status is due to newer and more favorable antihypertensive medications with better side effects.

How long does reserpine last?

Reserpine administered via the oral route is rapidly absorbed, reaching its peak concentration level after approximately 2 hours. Reserpine has a bioavailability of approximately 50% to 70% and an elimination half-life of 11.5 days. Administering reserpine beyond the upper dosage limit can lead to central nervous system depression, bradycardia, hypotension, lethargy, and coma. Reserpine is assigned Pregnancy Category C.
