Abstract

This study aimed to develop a nanoparticle drug delivery system using poly (lactic-co-glycolic acid) (PLGA) for enhancing the therapeutic efficacy of lurasidone hydrochloride (LH) in treatment of schizophrenia through intramuscular injection. LH-loaded PLGA nanoparticles (LH-PNPs) were prepared using the nanoprecipitation technique and their physicochemical characteristics were assessed. Particle size (PS), zeta potential, morphology, % encapsulation efficiency, % drug loading, drug content, and solid-state properties were analyzed. Stability, in vitro release, and in vivo pharmacokinetic studies were conducted to evaluate the therapeutic efficacy of the developed LH-PNPs. The optimized batch of LH-PNPs exhibited a narrow and uniform PS distribution before and after lyophilization, with sizes of 112.7 ± 1.8 nm and 115.0 ± 1.3 nm, respectively, and a low polydispersity index. The PNPs showed high drug entrapment efficiency, drug loading, and drug content uniformity. Solid-state characterization indicated good stability and compatibility, with a nonamorphous state. The drug release profile demonstrated sustained release behavior. Intramuscular administration of LH-PNPs in rats resulted in a significantly prolonged mean residence time compared with the drug suspension. These findings highlight that intramuscular delivery of the LH-PNP formulation is a promising approach for enhancing the therapeutic efficacy of LH in treatment of schizophrenia.

优化用于肌内给药的 Lurasidone HCl-Loaded PLGA 纳米颗粒:提高生物利用度、减少给药次数、药代动力学和治疗效果。
本研究旨在利用聚乳酸-聚乙二醇酸(PLGA)开发一种纳米颗粒给药系统,通过肌肉注射提高盐酸鲁拉西酮(LH)治疗精神分裂症的疗效。研究人员采用纳米沉淀技术制备了负载 LH 的 PLGA 纳米粒子(LH-PNPs),并对其理化特性进行了评估。分析了颗粒尺寸(PS)、ZETA电位、形态、包封效率%、载药率%、药物含量和固态特性。为评估所开发 LH-PNPs 的疗效,还进行了稳定性、体外释放和体内药代动力学研究。优化批次的 LH-PNPs 在冻干前和冻干后的 PS 分布窄且均匀,尺寸分别为 112.7 ± 1.8 nm 和 115.0 ± 1.3 nm,多分散指数较低。PNPs 具有较高的药物包载效率、药物负载量和药物含量均匀性。固态表征表明其具有良好的稳定性和相容性,呈非晶态。药物释放曲线显示了持续释放行为。与药物悬浮液相比,大鼠肌肉注射 LH-PNPs 可显著延长平均停留时间。这些研究结果表明,肌肉注射 LH-PNP 制剂是提高 LH 治疗精神分裂症疗效的一种可行方法。
