摘要:
Objective To prepare 1% voriconazole eye drops, establish its method of quality control and inspect the eye irritation. Methods Voriconazole was solubilizing by SBE-β-CD in order to prepare voriconazole eye drops. The content of voriconazole was determined by HPLC, observed stability and irritation to rabbits'eyes of voriconazole eye drops. Results The eye-drops was colorless and transparent liquid, specification of 5 mL: 50 mg, content of voriconazole was 1%. Its identification and test conformed to the related standards stated in Ch.P(2015). There was a good linear relationshop with the concentration range of 20~800μg/mL(r=0.9999, n=6)for voriconazole, and its average recovery was 100.13%(RSD=0.78%, n=9). Both intra- and inter-day precision RSD were less than 2%(n=5). The eye drops had no irritation to rabbits'eyes, accelerated stability test is good. Conclusion The preparation process of voriconazole eye drops is simple, its quality control method is reliable.%目的 制备1%伏立康唑滴眼液,建立质量控制方法并进行眼刺激性试验.方法 以SBE-β-CD为增溶剂来制备伏立康唑滴眼液,采用高效液相色谱法测定主药含量,考察滴眼液的稳定性及兔眼刺激性.结果 所得制剂为无色澄明液体,规格为5 mL:50 mg,含药量为1.0%;鉴别、检查结果均符合2015版中国药典中的相关规定,伏立康唑检测浓度的线性范围为20~800μg/mL(r=0.9999,n=6),平均回收率为100.13%(RSD=0.78%,n=9),日内和日间精密度RSD均小于2%(n=5),该滴眼液对兔眼无刺激性,稳定性良好.结论 本制剂处方及工艺简单、质量可控,无眼部刺激性,适用于医院配制使用.
