生物活性
Clobetasol propionate is a anti-inflammatory corticosteroid used to treat various skin disorders including eczema and psoriasis. Clobetasol propionate is also highly effective for contact dermatitis caused by exposure to poison ivy/oak. Clobetasol belongs to US Class I (Europe: class IV) of the corticosteroids, making it one of the most potent available. Clobetasol propionate has very high potency and typically should not be used with occlusive dressings, or for extended continuous use (beyond two weeks). Clobetasol propionate is also used to treat several auto-immune diseases including alopecia areata, vitiligo and lichen planus.

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。
