生物活性
Cloxacillin sodium (Cloxacap) is a sodium salt of cloxacillin that is a penicillinase-resistant, acid resistant, semi-synthetic penicillin. Cloxacillin sodium exerts a bactericidal action against susceptible microorganisms during the stage of active multiplication. Cloxacillin sodium acts through the inhibition of biosynthesis of cell wall mucopeptides. Cloxacillin sodium is readily absorbed following i.m. administration and rapidly reaches therapeutically effective blood levels. Serum levels are approximately proportional to dosage. Peak plasma concentrations of 15 ug/ml have been observed 30 minutes after an i.m. injection of cloxacillin (Cloxapen, Cloxacap and Orbenin) 500 mg; plasma concentrations may be doubled by administration of a doubled dose. At the end of a 3-hour i.v. infusion of cloxacillin (Cloxapen, Cloxacap and Orbenin) 250 mg given to normal subjects, its plasma concentrations were 15 ug/ml. After 2 hours, plasma concentrations were 0.6 ug/ml.

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。
