注射用加替沙星与注射用头孢拉定的配伍稳定性考察

Study on the Compatibility of Gatifloxacin for Injection with Cefradine for Injection

目的:考察注射用加替沙星与注射用头孢拉定分别在5%葡萄糖注射液和0.9%氯化钠注射液中的配伍稳定性。方法:分别观察及测定配伍液在室温下放置8h内的外观及pH值变化,并用紫外分光光度法测定其含量。结果:两药配伍后,外观无明显变化,而pH值及含量变化很大。结论:注射用加替沙星与注射用头孢拉定存在配伍禁忌。

OBJECTIVE:To observe the compatibility of gatifloxacin for injection with cefradine for injection in 5% glucose injection and in 0.9% sodium chloride injection respectively.METHODS:At room temperature for8hours the change in appearance and pH value were observed,while the content was determined by UV spectrophotometry as well.RESULTS:There was no evident change in appearance after the mixture,but the pH value and concentration changed significantly.CONCLUSIONS:There exists incompatibility between gatifloxacin for injection and cefradine for injection.
