Description

General description

Capsaicin occurs as the active ingredient of hot/red pepper and was first obtained by Thresh in 1846. It is a lipophilic vanilloid compound responsible for the acrid taste of hot peppers.

Application

Capsaicin has been used in the development and pharmaceutical production of a gastrointestinal mucosal protective drug.

Biochem/physiol Actions

Capsaicin shows its activity by binding to vanilloid receptors and eliciting a nociceptive response. It shows an analgesic effect in neuropathic and musculoskeletal disorders. Capsaicin is also used in the management of bladder detrusor hyperreflexia.

Prototype vanilloid receptor agonist. Neurotoxin; activates sensory neurons that give rise to unmyelinated C-fibers, many of which contain substance P. Topical application desensitizes the sensory nerve endings giving a paradoxical antinociceptive effect; systemic administration can be neurotoxic to capsaicin-sensitive cells, especially in newborn animals. Active component of chili peppers.

Prototype vanilloid receptor agonist; neurotoxin. Active component of chili peppers.
