用途: Sitafloxacin Hydrate is a new-generation, broad-spectrum oral fluoroquinolone antibiotic.Target: AntibacterialSitafloxacin Hydrate, a new-generation, broad-spectrum oral fluoroquinolone that is very active against many Gram-positive, Gram-negative and anaerobic clinical isolates, including strains resistant to other fluoroquinolones, was recently approved in Japan for the treatment of respiratory and urinary tract infections [1]. In terms of clinical efficacy, oral sitafloxacin was noninferior to oral levofloxacin in the treatment of community-acquired pneumonia or an infectious exacerbation of chronic respiratory tract disease, noninferior to oral tosufloxacin in the treatment of community-acquired pneumonia, and noninferior to oral levofloxacin in the treatment of complicated urinary tract infections, according to the results of randomized, double-blind, multicentre, noninferiority trials. Noncomparative studies demonstrated the efficacy of oral sitafloxacin in otorhinolaryngological infections, urethritis in men, C. trachomatis-associated cervicitis in women and odontogenic infections [2]. 作用: 西他沙星具有广谱抗菌作用,对革兰阴性菌抗菌活性显著,活性要强于环丙沙星和氧氟沙星,同时对革兰阳性菌(耐甲氧西林金黄色葡萄球菌、耐甲氧西林表皮葡萄球菌)、厌氧菌(包括脆弱类杆菌)以及支原体、衣原体等具有较强的抗菌活性,对许多临床常见耐氟喹诺酮类菌株也具有良好杀菌作用。本品口服吸收好、生物利用率大于70%,组织分布广,在中枢神经系统外的多种组织中的药物浓度均高于血清药物浓度,因此,本品有望成为治疗呼吸道、泌尿生殖道、腹腔以及皮肤软组织等单一或混合细菌感染的重要药物。 物理化学性质: CAS号:163253-35-8 常用中文名:西他沙星水合物 常用英文名:Sitafloxacin hydrate 分子式:C19H18ClF2N3O3.3/2H2O 分子量:436.84 密度:N/A 沸点:629.2ºC at 760mmHg 熔点:145-147°C (dec.) 闪点:334.3ºC 储存条件:Hygroscopic, -20°C Freezer, Under Inert Atmosphere |
