目的 优化虎力散凝胶贴膏(Hulisan gel plaster,HLS-GP)成型工艺,并进行初步药效学考察。方法 以初黏力、持黏力、黏着力和感官评分为指标,正交试验优化HLS-GP成型工艺;以党参炔苷、三七皂苷R1(notoginsenoside R1,NR1)、8-去乙酰滇乌碱(8-deacetyl yunaconitine,8D-YNA)、滇乌碱和人参皂苷Rg1(ginsenoside Rg1,GRg1)为指标,考察HLS-GP体外释药性及经皮渗透性,并从氮酮、丙二醇和薄荷脑中筛选最佳促渗剂;通过耳肿胀和醋酸扭体模型,初步探讨HLS-GP的抗炎镇痛作用。结果 HLS-GP的最佳处方为NP700 11 g,甘羟铝0.8 g,高岭土1.5 g,甘油40 g,酒石酸0.8 g,PVPK90 6 g,水20 g,验证实验结果符合要求。建立的党参炔苷、NR1、8D-YNA、滇乌碱和GRg1定量测定方法适用性好;5种成分24 h的累积释放率分别为(65.93±0.10)%、(77.42±0.13)%、(80.08±0.87)%、(69.86±0.17)%、(21.90±0.68)%,释放行为均符合一级动力学方程;筛选得到的最佳促渗剂为5%丙二醇,5种成分24 h的累积渗透量分别为(136.16±0.07)、(319.50±0.05)、(16.92±0.05)、(10.27±0.06)、(166.69±0.08)μg/cm2;抗炎镇痛结果表明,与对照组相比,模型组小鼠耳肿胀明显、潜伏期短、扭体次数多,而HLS-GP能够显著抑制小鼠耳肿胀、延长潜伏期,并减少扭体次数(P<0.05、0.01);同时,HLS-GP能够显著降低小鼠血清中炎症因子白细胞介素-6(interleukin-6,IL-6)、IL-1β、肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α)和5-羟色胺(5-hydroxytryptamine,5-HT)、前列腺素E2(prostaglandin E2,PGE2)的水平(P<0.05、0.01)。结论 制得具有良好体外释药性和经皮渗透性的HLS-GP,且具有良好的抗炎镇痛作用,为虎力散经皮给药制剂的开发奠定基础。

[Abstract]
Objective To optimise the forming process of Hulisan gel plaster (HLS-GP, 虎力散凝胶贴膏) and conduct preliminary pharmacodynamic investigation. Methods Orthogonal test was used to optimise the forming process of HLS-GP with initial tack, holding power, adhesion and sensory score as indicators. Lobetyolin, notoginsenoside R1 (NR1), 8-deacetyl-yunaconitine (8D-YNA), yunaconitine and ginsenoside Rg1 (GRg1) were used as indicators to investigate the in vitro release and transdermal permeability of HLS-GP and to screen for the optimal osmotic enhancer from azone, propylene glycol and menthol. A preliminary investigation of the anti-inflammatory and analgesic effects of HLS-GP through ear swelling and acetic acid writhing modelling. Results The optimum formulation of HLS-GP was 11 g NP700, 0.8 g aluminium glycinate, 1.5 g kaolin, 40 g glycerol, 0.8 g tartaric acid, 6 g PVP K90 and 20 g water, which confirmed that the results of the experiment met the requirements. The established methods for the determination of 8D-YNA, yunaconitine, lobetyolin, NR1 and GRg1 contents were applicable. And the 24 h cumulative release rates were (65.93 ±0.10)%, (77.42 ±0.13)%, (80.08 ±0.87)%, (69.86 ±0.17)% and (21.90 ±0.68)%, respectively, and the release behaviour followed the first-order kinetic equation. The optimal osmotic enhancer obtained from the screening was 5% propylene glycol, and the cumulative osmolality of the five components at 24 h were (136.16 ±0.07), (319.50 ±0.05), (16.92 ±0.05), (10.27 ±0.06) and (166.69 ±0.08) μg/cm2, respectively. The anti-inflammatory and analgesic results showed that, compared with the control group, mice in the model group had obvious ear swelling, short latency, and a high number of writhing, whereas HLS-GP was able to significantly inhibit ear swelling, prolong latency, and reduce the number of writhing in the mice (P < 0.05). At the same time, HLS-GP was able to significantly reduce the serum levels of the inflammatory factors interleukin-6 (IL-6), IL-1β and tumor necrosis factor-α (TNF-α) in the mice with ear swelling and significantly reduce the serum levels of 5-hydroxytryptamine (5-HT), IL-1β and prostaglandin E2 (PGE2) in the acetate writhing mice (P < 0.05, 0.01). Conclusion HLS-GP with good in vitro drug release and transdermal permeability and good anti-inflammatory and analgesic effects were obtained, which can lay the foundation for the development of transdermal drug delivery formulations of Hulisan.
