Unravelling the Mystery of Capsaicin: A Tool to Understand and Treat Pain

The rationale of this review is to bring together and discuss the different types of studies that exploit capsaicin actions to shed light upon Capsaicin working both as a tool to understand pain but also as a treatment for chronic pain.

Role of extrinsic afferent neurons in gastrointestinal motility.

It is proposed that NO may be a sensory neurotransmitter, which plays a role in sympathetic reflexes, such as the inhibition of GI motility after laparotomy or by peritoneal irritation in animals with functionally inhibited capsaicin-sensitive nerves.

Facilitation and inhibition by capsaicin of cholinergic neurotransmission in the guinea-pig small intestine

Capsaicin has a dual effect on cholinergic neurotransmission and the facilitatory effect is indirect and involves tachykinin release and excitation of NK1 and NK3 receptors on cholinergic neurons.

High-Concentration Piperine: Capsaicin-Sensitive and -Insensitive Effects on Isolated Organs

The current isolated organ study in the guinea-pig ileum, urinary bladder and trachea confirms the presence of such components of effect and indicates TRPV1 involvement in the effect of 5 or 30 µmol/l of P on the basis of an inhibitory action of the antagonist BCTC.

Capsaicin, Nociception and Pain

The chemical and pharmacological properties of capsaicin and its derivatives in relation to their analgesic properties are described and the use of Capsaicin as an agonist of TRPV1 to model acute inflammation in slices and other ex vivo preparations is discussed.

Functional study on TRPV1‐mediated signalling in the mouse small intestine: involvement of tachykinin receptors

Activation of TRPV1 in the mouse intestine induces a contraction that is mediated by tachykinins most likely released from afferent nerves, which does not involve activation of intrinsic enteric motor nerves.

The mouse main bronchus appears to be a monoreceptorial tissue containing only NK1 receptors which subserve bronchodilator functions and the consequent relaxation is probably mediated by the generation of prostanoids.

Release of Calcitonin Gene—Related Peptide from Sensory Neurons a

CGRP released upon irritation of peripheral branches of primary afferents may evoke a variety of cardiovascular actions and influence motility in the gastrointestinal and urogenital tracts.

Effect of capsaicin on smooth muscles of rat vas deferens: involvement of calcitonin gene-related peptide?

The results suggest that capsaicin releases endogenous C GRP and that the released CGRP inhibits the contraction of the rat vas deferens by acting directly on smooth muscle cells but not on the sympathetic nerves.
