Vilanterol (GW642444; GW 642444X) is a novel, inhaled, long-acting β(2) agonist with inherent 24-h activity under development as a once-daily combination therapy with an inhaled corticosteroid for COPD and asthma.
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
