Nicorandil(Ikorel)is potassium channel activator. It acts by relaxing the smooth muscle of the blood vessels, especially those of the venous system. It does this through two methods. Firstly, by activating potassium channels, and secondly by donating nitric oxide to activate the enzyme guanylate cyclase. Guanylate cyclase causes activation of cGMP leading to both arterial and venous vasodilatation by de-phosphorylation of the myosin light chain.

Conversion of different model animals based on BSA(Value based on data from FDA Draft Guidelines)
Animal A (mg/kg)=Animal B(mg/kg)multiplied by AnimalBm系数/AnimalAm系数 For example, to modify the dose of resveratrol uesd for a mouse(22.4mg/kg) to a dose based on the BSA for a rat, multiply 22.4mg/kg by the Km factor for a mouse and zhen divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2mg/kg
