Zucapsaicin (Civanex) is a medication used to treat osteoarthritis of the knee and other neuropathic pain. Zucapsaicin is a member of phenols and a member of methoxybenzenes. 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. It is the cis-isomer of capsaicin. Civamide, manufactured by Winston Pharmaceuticals, is produced in formulations for oral, nasal, and topical use (patch and cream).

Zucapsaicin has been tested for treatment of a variety of conditions associated with ongoing nerve pain. This includes herpes simplex infections; cluster headaches and migraine; and knee osteoarthritis. It was approved by the Health Canada in 2010 as topical cream sold under the brand name Zuacta. It has a melting point of 71.5–74.5 °C.
