Biochem/physiol Actions
A β-lactam antibiotic with an amino group side chain attached to the penicillin structure. Penicillin derivative that inhibits bacterial cell-wall synthesis (peptidoglycan cross-linking) by inactivating transpeptidases on the inner surface of the bacterial cell membrane. Bactericidal only to growing Escherichia coli . Mode of resistance: Cleavage of β-lactam ring of ampicillin by β-lactamase. Antimicrobial spectrum: Gram-negative and Gram-positive bacteria.
别名：氨苄青霉素钠/氨苄西林钠/ D(-)-6-(α-氨基-苯乙酰胺)青霉烷酸/(2S,5R,6R)-3,3-二甲基-6-[(R)-2-氨基-2-苯乙酰氨基]-7-氧代-4-硫杂-1-氮杂双环[3.2.0]庚烷-2-甲酸钠盐/Ampicillin sodium salt
药品为广谱半合成青霉素，毒性极低。抗菌谱与青霉素相似，对青霉素敏感的细菌效力较低，对草绿色链球菌的抗菌作用与青霉素相仿或略强。对白喉杆菌、破伤风杆菌和放线菌其效能基本和青霉素相同。对肠球菌及李斯特菌的作用则优于苄青霉素。对耐药葡萄球菌及其它能产生青霉素酶的细菌均无抗菌作用。对革兰阴性菌有效，但易产生耐药性。
