An RP-HPLC method has been developed for the simultaneous determination of butenafine hydrochloride and betamethasone dipropionate on an Inertsil C18 column (250 x 4.6 mm id) using a mobile phase gradient consisting of methanol and water at a flow rate of 1 mL/min. Detection was carried out at 254 nm. Retention times of betamethasone dipropionate and butenafine hydrochloride were 4.82 (+/- 0.80) and 16.18 (+/- 0.17) min, respectively. The method was validated with respect to specificity, linearity, accuracy, precision, ruggedness, and robustness. This method is simple, precise, and sensitive, and applicable for the simultaneous quantification of butenafine hydrochloride and betamethasone dipropionate in a cream formulation.
已开发出一种反相高效液相色谱法，用于在Inertsil C18柱（250×4.6 mm内径）上同时测定盐酸布替萘芬和二丙酸倍他米松，流动相梯度由甲醇和水组成，流速为1 mL/分钟。检测波长为254 nm。二丙酸倍他米松和盐酸布替萘芬的保留时间分别为4.82（±0.80）分钟和16.18（±0.17）分钟。该方法在特异性、线性、准确度、精密度、耐用性和稳健性方面得到了验证。该方法简单、精确、灵敏，适用于同时定量乳膏制剂中的盐酸布替萘芬和二丙酸倍他米松。
