目的制备复方奥硝唑中空栓剂,并建立质量控制方法。方法以混合脂肪酸甘油酯为基质制备中空栓剂;采用等吸收-双波长法同时测定其主药奥硝唑和左氧氟沙星的含量;对制剂进行卫生学、刺激性及稳定性等试验。结果奥硝唑和左氧氟沙星的平均回收率(n=9)分别为99.7%,100.2%,其他各项检查均符合栓剂的有关规定。结论本制剂制备工艺简单,性质稳定,质量可控。
Objective To prepare the compound ornidazole hollow suppository and establish the quality control method. Methods Hollow suppositories were prepared with mixed fatty acid glyceride as matrix. The content of ornidazole and levofloxacin, the main drug, was determined by the method of isobsorption - double wavelength. The preparation was tested for hygiene, irritation and stability. Results The mean recoveries of ornidazole and levofloxacin (n = 9) were 99.7% and 100.2%, respectively. All the other tests were in accordance with the relevant suppository. Conclusion The preparation process is simple, stable in nature and quality controllable.
