Biochem/physiol Actions

Nitecapone is a short-acting inhibitor of catechol-O-methyltransferase (COMT). Nitecapone displays in vivo activity in peripheral tissues, but does not pentrate the blood brain barrier. The compound increases mechanical and thermal nociception, and reduces neuropathic pain in diabetic rats and in a spinal nerve ligation model.
