Abstract:
Objective:To prepare compound mupirocin film forming gel and establish the quality control methods. Methods:The compound film forming gel was prepared using tannic acid and salicylic acid as the esterifying agents interacting with hydroxypropyl cel-lulose followed by cross-linking with tartaric acid and sorbitol to form a new film forming material, and then antimicrobial mupirocin and anesthetic dyclonine were added to prepare compound mupirocin film forming gel. The contents of mupirocin and dyclonine were deter-mined by HPLC. The column was Hypersil ODS2 (250 mm × 4. 6 mm, 5 μm) and the mobile phase consisted of methanol-ammonium acetate buffer (1. 15 g ammonium acetate, 300 ml water, 1 ml glacial acetic acid) (75 :25). The flow rate was 1. 0 ml·min-1 and the detection wavelength was 230 nm. The column temperature was 30℃ and the injection volume was 20μl. Results:The film form-ing gel was yellow, brown and gelatinous at the normal temperature, and formed transparent film after coating on the skin. The linear range of mupirocin and dyclonine was 20-400μg﹒ml-1(r=0. 9999) and 10-200μg﹒ml-1(r=0. 9996), respectively. The aver-age recovery was 99.9%(RSD=0.54%, n=9) and 99.6%(RSD =1.45%, n =9), respectively. Conclusion: The preparation process is reasonable, simple and controllable in the preparation of ideal film forming gel.
