Recent treatment approaches of osteoarthritis (OA) face a number of obstacles due to the progressive multitude of pain generators, nociceptive mechanisms, first pass mechanism, less efficacy and compromised safety. The present study was aimed to bring a novel approach for the effective management of OA, by developing sublingual targeted nanovesicles (NVs) bearing tapentadol HCl (TAP), surface modified with chondroitin sulphate (CS). Optimised nontargeted nanovesicle formulation (MB-NV) was developed by an ultrasound method, characterised as spherical in shape, nanometric in size (around 150 nm) with narrow size distribution (polydispersity index <0.5), and good entrapment efficiency (around 50%). MB-NV conjugated with CS which was confirmed by IR and 1H NMR spectroscopy. C-MB-NV showed improved pharmacokinetics parameters i.e. increased t1/2 (9.7h), AUC (159.725 μg/ml*h), and MRT(14.99h) of TAP than nontargeted formulation and plain drug soln. C-MB-NV in In vitro release studies proved sustained drug release pattern for more than 24 h following Higuchi model kinetics with Fickian diffusion (n ≤ 0.5).Targeted nanovesicles exhibited an improved bioavailability and enhanced analgesic activity in a disease-induced wistar rat model which indicated the superior targeting potential of C-MB-NV exploiting CD44 receptors as mediators, overexpressed at the affected joints in the OA model. It could be a propitious approach to accustomed therapies for methodical and efficient management in advanced OA therapy.

舌下给药硫酸软骨素结合的他喷他多纳米囊泡治疗骨关节炎

由于越来越多的疼痛发生器、伤害性机制、首过机制、较低的疗效和安全性,最近的骨关节炎 (OA) 治疗方法面临许多障碍。本研究旨在通过开发含他喷他多盐酸盐 (TAP)、表面用硫酸软骨素 (CS) 改性的舌下靶向纳米囊泡 (NVs),为有效管理 OA 带来一种新方法。优化的非靶向纳米囊泡制剂 (MB-NV) 是通过超声方法开发的,其特征是球形、纳米尺寸(约 150 nm)、窄尺寸分布(多分散指数 <0.5)和良好的包埋效率(约 50%) . MB-NV 与 CS 共轭,经 IR 和 1H NMR 光谱证实。C-MB-NV 显示出改善的药代动力学参数,即增加 t1/2 (9. 7h)、AUC (159.725 μg/ml*h) 和 TAP 的 MRT (14.99h) 与非靶向制剂和普通药物溶液相比。体外释放研究中的 C-MB-NV 证明了在具有 Fickian 扩散的 Higuchi 模型动力学后超过 24 小时的持续药物释放模式(n ≤ 0.5)。靶向纳米囊泡在疾病诱导的 wistar 大鼠中表现出改善的生物利用度和增强的镇痛活性模型表明 C-MB-NV 利用 CD44 受体作为介质的优越靶向潜力,在 OA 模型中受影响的关节处过度表达。它可能是一种有益的方法,用于在高级 OA 治疗中进行有条不紊和有效管理的习惯疗法。体外释放研究中的 C-MB-NV 证明了在具有 Fickian 扩散的 Higuchi 模型动力学后超过 24 小时的持续药物释放模式(n ≤ 0.5)。靶向纳米囊泡在疾病诱导的 wistar 大鼠中表现出改善的生物利用度和增强的镇痛活性模型表明 C-MB-NV 利用 CD44 受体作为介质的优越靶向潜力,在 OA 模型中受影响的关节处过度表达。它可能是一种有益的方法,用于在高级 OA 治疗中进行有条不紊和有效管理的习惯疗法。体外释放研究中的 C-MB-NV 证明了在具有 Fickian 扩散的 Higuchi 模型动力学后超过 24 小时的持续药物释放模式(n ≤ 0.5)。靶向纳米囊泡在疾病诱导的 wistar 大鼠中表现出改善的生物利用度和增强的镇痛活性模型表明 C-MB-NV 利用 CD44 受体作为介质的优越靶向潜力,在 OA 模型中受影响的关节处过度表达。它可能是一种有益的方法,用于在高级 OA 治疗中进行有条不紊和有效管理的习惯疗法。在 OA 模型中受影响的关节处过度表达。它可能是一种有益的方法,用于在高级 OA 治疗中进行有条不紊和有效管理的习惯疗法。在 OA 模型中受影响的关节处过度表达。它可能是一种有益的方法,用于在高级 OA 治疗中进行有条不紊和有效管理的习惯疗法。
