Description

Transient receptor potential vanilloid type 1 (TRPV1) is a member of the transient receptor potential (TRP) family that is activated or sensitized by a variety of endogenous stimuli as a result of tissue injury and inflammation. TRPV1 is upregulated during inflammation and plays a role in the perception of pain.1,2 Capsazepine is a competitive antagonist of TRPV1 which blocks the capsaicin-induced uptake of Ca2+ in neonatal rat dorsal root ganglia with an IC50 of 0.42 µM and Chinese hamster ovary cells with an IC50 of 17 nM.1,3 It does not block acid- or heat-induced activation of TRPV1 and may block receptors other than TRPV1.4,5
