摘要: 益康唑软膏是由益康唑与适宜基质制成的外用制剂。其基质由十八醇、十二烷基硫酸钠、白凡士林、甘油、香精、尼泊金乙酯和水按一定比例混合而成。采用定氮法测定益康Abstract: Econazole has a larger absorption but the ointment base has less absorption in ultraviolet region. Interference of base absorption in econazole contained in the ointment can be eliminated with a dual-wavelength spectrophotometry and therefore content of e
