TITLE:
摘要: 目的:制备盐酸氨溴索凝胶膏剂,并研究其体外透皮特性。方法:以聚乙烯醇、甘氨酸铝、聚丙烯酸钠等基质制备盐酸氨溴索凝胶膏剂。在单因素考察基础上,采用Box-Behnken响应面法,以外观性状、初黏力、持黏力、剥离强度的综合评分为指标优化处方中聚乙烯醇、甘氨酸铝、聚丙烯酸钠的用量,并进行验证试验。通过改良Franz扩散池法考察所制凝胶膏剂的体外透皮特性。结果:最优处方为聚丙烯酸钠2.35 g、甘氨酸铝0.1 g、聚乙烯醇1.0 g;所制3批凝胶膏剂的综合评分分别为9.4、9.5、9.7,与预测值比较的相对误差分别为2.08%、1.04%、1.04%;24 h内盐酸氨溴索的体外透皮速率为9.472 μg/(cm2·h),符合零级动力学模型(r=0.994)。结论:凝胶膏剂处方合理,具有较好的透皮特性,透皮行为符合零级动力学过程。
ABSTRACT: OBJECTIVE: To prepare Ambroxol hydrochloride hydrogel patch and study its transdermal permeability in vitro. METHODS: Polyvinyl alcohol (PVA), aluminum glycinate and polyacrylic acid sodium (PAAS) were used as excipients to prepare Ambroxol hydrochloride hydrogel patch. Based on single factor experiments, using appearance and property, initial bonding strength, endurance bonding strength and peel strength as indexes, Box-Behnken response methodology was used to optimize the amount of PVA, aluminum glycinate and PAAS. Validation test was also conducted. The transdermal permeability in vitro of prepared hydrogel patch was investigated by Franz diffusion cells. RESULTS: The optimal prescription was as follows as PAAS 2.35 g, aluminum glycinate 0.1 g, PVA 1.0 g. Comprehensive score of 3 batches of hydrogel patch were 9.4, 9.5, 9.7, respectively; relative errors were 2.08%, 1.04%, 1.04% compared with the predicted values. Within 24 hours, the transdermal rate of ambroxol hydrochloride was 9.472 μg/(cm2·h), which was up to zero-order kinetic model (r=0.994). CONCLUSIONS: Hydrogel patch formula is reasonable and shows good transdermal properties. Its transdermal absorption meets zero-order kinetic process.
