生物活性
Amoxicillin sodium (Amox) is a moderate- spectrum, bacteriolytic, β-lactam antibiotic. Amoxicillin sodium (Amox) is used to treat bacterial infections caused by susceptible microorganisms. Amoxicillin sodium (Amox) is usually the drug of choice within the class because it is better absorbed, following oral administration, than other β-lactam antibiotics. Amoxicillin sodium (Amox) is susceptible to degradation by β-lactamase-producing bacteria, which are resistant to a broad spectrum of β-lactam antibiotics, such as penicillin. For this reason, it is often combined with clavulanic acid. Amoxicillin sodium (Amox) acts by inhibiting the synthesis of bacterial cell walls. Amoxicillin sodium (Amox) inhibits cross-linkage between the linear peptidoglycan polymer chains that make up a major component of the cell walls of both Gram-positive and Gram-negative bacteria.

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。
