Description
技术领域
本公开属于药物制剂领域,具体涉及一种包含S-氟比洛芬的外用剂组合物。
背景技术
氟比洛芬是一种外消旋体的丙酸类非甾体抗炎药(NSAIDs),主要用于治疗类风湿关节炎、骨关节炎、强直性脊柱炎、外伤疼痛和其他疼痛。氟比洛芬通过抑制前列腺素合成酶环氧酶的活性从而起到消炎镇痛的作用。与口服给药相比,当用于外伤及关节、软组织、肌肉的炎症产生的疼痛时,采用外用制剂可以降低口服给药的副作用并加快药物起效速度。Chirality,1993,5(7):492-494和Mod Rheumatol,2017,27(1):130-136等多篇文献已经对氟比洛芬的两个对映体进行了相关研究,研究表明,氟比洛芬对映体中S型能更有效抑制环氧化酶,具有消炎镇痛效果,R型在此方面几乎没有治疗作用,而且表现出一些毒副反应和生理抵抗作用,尤其是S-氟比洛芬大大降低了氟比洛芬在消化道方面的副作用。
现有技术中,作为含有S-氟比洛芬的外用剂组合物,US5776484公开了含薄荷油和多元醇的中链脂肪酸酯SEFSOL作为经皮吸收促进剂的S-氟比洛芬外用贴剂。CN107148269A公开了包含S-氟比洛芬、薄荷油和二辛酸丙二醇酯的外用贴剂,但在储存稳定性方面尚存在进一步改善的余地。
