Nicorandil is N-(2-hydroxyethyl)-nicotinamide nitrate (ester). It is a white crystalline powder or white needles with a faint, characteristic odour. It is freely soluble in methan ol, ethanol, aceto ne or glacial acetic acid, slightly soluble in chloro form or water, almost insoluble in ether or benzene. Melting point 88.5-93.5 ºC. Acute toxicity LD50 rat (mg/kg): 1200-1300 orally, 800-1000 intravenously.Nicorandil is a nitric oxid e donor and ATP-sensitive potassium channel opener. A study showed that Nicorandil is able to protect against stress-induced cell death in dystrophin-deficient cardiomyocytes and also preserve cardiac function in the mdx mouse heart subjected to ischemia and reperfusion injury.
Dufite inganda nyinshi zo mu rwego rwo hejuru hamwe nubufatanye bwimbitse, zishobora kuguha ibicuruzwa byiza kandi nibiciro byapiganwa. Turashobora kandi gutanga kugabanyirizwa kugura byinshi.Kandi turafatanya namasosiyete menshi yohereza ibicuruzwa byumwuga, birashobora gutanga ibicuruzwa neza kandi neza mumaboko yawe. Igihe cyo gutanga ni iminsi 3-20 nyuma yo kwemeza ko wishyuye.
