Abstract

Mebeverine hydrochloride (MBH) is an antispasmodic drug that holds the potential to exert a local anesthetic action via blocking voltage operated sodium channels. However, its local anesthetic activity was not yet exploited due its poor skin permeability. Nanocarriers have emerged as efficient vehicles for delivering both lipophilic and hydrophilic drugs through the stratum corneum. In this study, therefore, the efficacy of ethosomes for delivering MBH via skin for local anesthetic effect was investigated. The ethosomes were formulated, optimized and characterized for particle size, zeta potential, entrapment efficiency and in vitro permeation studies. Then, the optimized formula was incorporated into Carbopol 940® gel and evaluated for skin irritation and in vivo local anesthetic action. Ethosomes were spherical in shape with vesicle sizes varied from 308.2 ± 18.2 nm to 78.8 ± 8.6 nm and entrapment efficiencies of 18-65%. In vitro drug permeation across rabbit ear skin revealed enhanced drug permeation and higher transdermal flux with ethosomal formulations, compared to aqueous drug solution. In addition, an ethosomal gel of optimized formula showed a potent local anesthetic effect as manifested by a 2.3-fold increase in the area under the efficacy curve (AUEC) of MBH loaded ethosomal gel, compared to the MBH gel. Furthermore, skin irritation experiments demonstrated that MBH ethosomal gel induced neither erythema nor edema upon application to rabbit skin. Collectively, MBH loaded ethosomal vesicles might represent a promising delivery vehicle for safe and efficient local anesthetic effect.

摘要

盐酸美贝维林(MBH)是一种抗痉挛药物,通过阻断电压门控钠离子通道,具有发挥局部麻醉作用的潜力。然而,由于其皮肤渗透性差,其局部麻醉活性尚未得到开发。纳米载体已成为通过角质层递送亲脂性和亲水性药物的有效载体。因此,在这项研究中,研究了通过皮肤传递 MBH 的乙醇osomes 的局部麻醉效果。对乙醇osomes 进行了配方设计、优化和粒径、ζ电位、包封效率和体外渗透研究。然后,将优化的配方纳入 Carbopol 940®凝胶中,并评估其皮肤刺激性和体内局部麻醉作用。乙醇osomes 呈球形,粒径从 308.2±18.2nm 变化到 78.8±8.6nm,包封效率为 18-65%。兔耳皮肤体外药物渗透研究表明,与水溶液药物相比,乙醇osomes 制剂增强了药物渗透和更高的透皮通量。此外,优化配方的乙醇osomal 凝胶表现出更强的局部麻醉作用,载有 MBH 的乙醇osomal 凝胶的疗效曲线下面积(AUEC)增加了 2.3 倍,与 MBH 凝胶相比。此外,皮肤刺激实验表明,MBH 乙醇osomal 凝胶施用于兔皮时既不会引起红斑也不会引起水肿。综上所述,载有 MBH 的乙醇osomal 囊泡可能是一种有前途的安全有效局部麻醉作用的递药载体。
