Alseroxylon

A plant extract used in medicine

Alseroxylon is a complex extract derived from the plant Rauvolfia serpentina, commonly known as Indian snakeroot. This extract is notable for its use in traditional and modern medicine, primarily for its antihypertensive and antipsychotic properties.

Composition

Alseroxylon is composed of several alkaloids, with the most prominent being reserpine. Other alkaloids present include ajmaline, ajmalicine, and serpentine. These compounds contribute to the pharmacological effects of the extract.

Pharmacological Effects

The primary action of Alseroxylon is its ability to lower blood pressure. This is achieved through the depletion of catecholamines and serotonin from central and peripheral neurons. Reserpine, the main active component, irreversibly binds to storage vesicles in adrenergic neurons, leading to a decrease in the release of neurotransmitters such as norepinephrine.

In addition to its antihypertensive effects, Alseroxylon has been used as an antipsychotic agent. It was historically used in the treatment of schizophrenia and other mental disorders due to its sedative properties.

Medical Uses

Alseroxylon has been used in the treatment of:

• Hypertension: By reducing peripheral vascular resistance, it helps in lowering blood pressure.
• Psychiatric disorders: It has been used to manage symptoms of psychosis and anxiety.

Side Effects

The use of Alseroxylon can lead to several side effects, primarily due to its action on the central nervous system. Common side effects include:

• Depression
• Bradycardia
• Nasal congestion
• Gastrointestinal disturbances

Historical Context

The use of Rauvolfia serpentina in traditional medicine dates back centuries, particularly in Ayurveda, where it was used to treat snake bites, fever, and mental illness. The isolation of reserpine in the mid-20th century marked a significant advancement in the treatment of hypertension and psychiatric disorders.
