替比培南匹伏脂的体外抗菌作用研究
The Chinese Journal of Clinical Pharmacology(2012)
Abstract
目的 评价替比培南匹伏脂的体外抗菌作用.方法 用琼脂对倍稀释法测定替比培南匹伏脂对519株临床分离菌的体外抗菌活性.结果 对革兰阳性球菌中的肺炎链球菌、化脓性链球菌及对甲氧西林敏感的金葡菌和凝固酶阴性的葡萄球菌,替比培南匹伏脂均显示良好的抗菌活性.尤其是对青霉素不敏感肺炎链球菌,替比培南匹伏脂的MIC50最低,为0.25 mg·L-1.本品对流感嗜血杆菌、卡他莫拉菌、产ESBLs和不产ESBLs的肺炎克雷伯菌和大肠埃希菌、易产诱导酶的阴沟肠杆菌、产气肠杆菌、枸橼酸杆菌、粘质沙雷菌的MIC50为≤0.03~5.00 mg· L-1,低于其他5种抗菌药物.结论 替比培南匹伏脂对社区感染中常见病原菌有较好的抗菌活性.
