生物活性
Prednisone (Adasone) is a synthetic corticosteroid agent that is particularly effective as an immunosuppressant compound. Prednisone (Adasone) is used to treat certain inflammatory diseases and (at higher doses) some types of cancer, but has significant adverse effects. Because prednisone (Adasone) suppresses the immune system, prednisone (Adasone) leaves patients more susceptible to infections. Prednisone (Adasone) is usually taken orally but can be delivered by intramuscular injection or intravenous injection. Prednisone (Adasone) has a mainly glucocorticoid effect. Prednisone (Adasone) is converted by the liver into prednisolone, which is the active compound and also a steroid.

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。
