Pizotifen is an antagonist of muscarinic receptors and a serotonin antagonist acting mainly at the 5-HT1, 5-HT2A and 5HT2C receptors with some antihistamine activity.
Pizotifen is an antagonist of muscarinic receptors and a serotonin antagonist acting mainly at the 5-HT1, 5-HT2A and 5HT2C receptors with some antihistamine activity. It is used for the prevention of vascular headache including migraine and cluster headache.
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。
