Nicorandil is a hybrid ATP-sensitive K+ (KATP) channel opener and nicotinamide nitrate NO donor. Selectively activates SUR2B- versus SUR2A-containing KATP channels. It enhances endothelial NO synthase expression and protects against ischemic ventricular arrhythmias. It attenuates MMP-2 and -9 plasma levels, thereby suppressing ventricular remodeling. A clinically useful antianginal agent. Product Specification MW:211.2 CAS:65141-46-0 Purity:98% Long Term Storage:-20°C
