用途: Clarithromycin is a macrolide antibiotic and a CYP3A4 inhibitor.Target: Antibacterial; CYP3A4Clarithromycin is a macrolide antibiotic used to treat pharyngitis, tonsillitis, acute maxillary sinusitis, acute bacterial exacerbation of chronic bronchitis, pneumonia (especially atypical pneumonias associated with Chlamydophila pneumoniae), skin and skin structure infections. Clarithromycin prevents bacteria from growing by interfering with their protein synthesis. It binds to the subunit 50S of the bacterial ribosome and thus inhibits the translation of peptides. Clarithromycin has similar antimicrobial spectrum as erythromycin, but is more effective against certain Gram-negative bacteria, particularly Legionella pneumophila. Besides this bacteriostatic effect, clarithromycin also has bactericidal effect on certain strains, such as Haemophilus influenzae, Streptococcus pneumoniae and Neisseria gonorrhoeae. Clarithromycin is a CYP3A4 inhibitor. Even low doses of the cytochrome P4503A4 (CYP3A4) inhibitor clarithromycin increase the plasma concentrations and effects of repaglinide. Concomitant use of clarithromycin or other potent inhibitors of CYP3A4 with repaglinide may enhance its blood glucose-lowering effect and increase the risk of hypoglycemia [1, 2]. 作用: 用途 大环内酯类抗生素,为红霉素的衍生物,把红霉素A的6位上的OH基改为OCH3,即为克拉霉素。对革兰阳性菌和阴性菌、衣原体以及分枝杆菌有效,几乎能有效地抑制所有呼吸系统病原菌。对胃酸稳定,口服吸收好,血药浓度高,血半衰期长。其用途和红霉素相似,对呼吸道、泌尿道、皮肤、耳鼻喉科等多种感染有效。 用途 属大环内酯类抗生素,用于治疗上、下呼吸道感染,皮下软组织感染等 物理化学性质: CAS号:81103-11-9 常用中文名:克拉霉素 常用英文名:Clarithromycin 分子式:C38H69NO13 分子量:747.953 密度:1.2±0.1 g/cm3 沸点:805.5±65.0 °C at 760 mmHg 熔点:217-220ºC 闪点:440.9±34.3 °C 储存条件:室温,密封 |
