用途: Cefaclor, is a second-generation cephalosporin antibiotic used to treat certain infections caused by bacteria such as pneumonia and infections of the ear, lung, skin, throat, and urinary tract.Target: AntibacterialCefaclor belongs to the family of antibiotics known as the cephalosporins (cefalosporins). The cephalosporins are broad-spectrum antibiotics that are used for the treatment of septicaemia, pneumonia, meningitis, biliary tract infections, peritonitis, and urinary tract infections. The pharmacology of the cephalosporins is similar to that of the penicillins, excretion being principally renal. Cephalosporins penetrate the cerebrospinal fluid poorly unless the meninges are inflamed; cefotaxime is a more suitable cephalosporin than cefaclor for infections of the central nervous system, e.g. meningitis. Cefaclor is active against many bacteria, including both Gram-negative and Gram-positive organisms.Cefaclor is frequently used against bacteria responsible for causing skin infections, otitis media, urinary tract infections, and others. The following represents MIC susceptibility data for a few medically significant microorganisms. Cefaclor is passed into the breast milk in small quantities, but is generally accepted to be safe to take during breastfeeding. Cefaclor is not known to be harmful in pregnancy. Cefaclor has also been reported to cause a serum sickness-like reaction in children. 作用: 头孢克洛为第二代口服头孢菌素,其抗菌作用机制与其他头孢菌素类药相似,主要通过与细菌细胞内的青霉素结合蛋白(PBPs)结合,抑制细菌细胞壁的生物合成而起杀菌作用。金黄色葡萄球菌、表皮葡萄球菌(包括产青霉素酶和非耐甲氧西西林菌株)、肺炎链球菌、白喉杆菌、克雷白菌属、梭状芽胞杆菌属、大肠杆菌、奇异变形杆菌、流感嗜血杆菌、淋球菌、肺炎球菌、伤寒沙门菌属、志贺菌属、脑膜炎球菌等对头孢克洛敏感。吲哚阳性变形杆菌、沙雷菌属、不动杆菌属和铜绿假单胞菌等对头孢克洛耐药。 物理化学性质: CAS号:53994-73-3 常用中文名:头孢克罗 常用英文名:cefaclor 分子式:C15H14ClN3O4S 分子量:367.807 密度:1.6±0.1 g/cm3 沸点:713.4±60.0 °C at 760 mmHg 熔点:N/A 闪点:385.2±32.9 °C 储存条件:室温,干燥 |
