生物活性
Pranlukast is a selective cysteinyl leukotriene receptor antagonist. Pranlukast has an anti-inflammatory effect on bronchial eosinophilic infiltration. Pranlukast is now widely used in the treatment of asthma. Many clinical studies have indicated that pranlukast is well tolerated and is effective in reducing bronchial hyperresponsiveness and allergen-induced bronchoconstriction. The anti-asthmatic effect of pranlukast may be rendered not only by antileukotriene activity, but also by pharmacological activity including antieosinophilic effects.

不同实验动物依据体表面积的等效剂量转换表(数据来源于FDA指南)
| 小鼠 | 大鼠 | 兔 | 豚鼠 | 仓鼠 | 狗 |
重量 (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
体表面积 (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
Km系数 | 3 | 6 | 12 | 8 | 5 | 20 |
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,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
