Scopolamine hydrobromide (氢溴酸东莨菪碱) 是毒蕈碱乙酰胆碱受体(mAChR)拮抗剂,IC50为55.3 nM。
Scopolamine HBr is a competitive muscarinic acetylcholine receptor with an IC50 of 55.3 nM.
动物 A (mg/kg) = 动物 B (mg/kg)×动物 B的Km系数/动物 A的Km系数 | |
例如,已知某工具药用于小鼠的剂量为88 mg/kg , 则用于大鼠的剂量换算方法:将88 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到该药物用于大鼠的等效剂量44 mg/kg。
