Vocacapsaicin hydrochloride

개요Vocacapsaicin, formerly designated as CA-008 HCl, is a novel prodrug of trans-capsaicin (trans-8-methyl-N-vanillyl-6-nonenamide) being developed as a nonopioid, site-specific treatment for postsurgical pain management. It is designed to provide long-lasting (at least 96h) postsurgical analgesia following a single intraoperative administration. The free base form of vocacapsaicin rapidly cyclizes under physiological conditions to yield active capsaicin and CA-101 (cyclic urea) as the sole conversion products. Vocacapsaicin was developed to improve the solubility profile of capsaicin and allow for an aqueous formulation that could be simply administered at the wound site to achieve a long-lasting analgesic effect. Vocacapsaicin has little or no pharmacologic activity as the intact prodrug and is rapidly converted to capsaicin[1].
