It is a modulator of transient receptor potential cation channel subfamily V member 1 (TRPV-1), also known as the vanilloid or capsaicin receptor 1, that reduces pain and improves articular functions. Zucapsaicin has also been evaluated for the management of several conditions manifested by chronic nerve pain. These conditions include herpes simplex (HSV) infections, cluster headaches, migraine, and osteoarthritis of the knee. Zucapsaicin was approved by the Health Canada in 2010 as topical cream marketed under the brand name Zuacta but currently not FDA-approved."}]
