Abstract

In today's medicine, progress often depends on new products with special qualities. Nanotechnology focuses on the creation of materials tailored to fulfill specific therapeutic requirements. This study aims to elucidate the potential of nanoparticles, particularly titanium dioxide nanoparticles, as carriers for pharmaceutical agents. To mitigate the release of potentially harmful titanium ions from the carrier's surface, modifications were implemented. In the initial phase, titanium dioxide, nanoparticles were obtained based on the sol-gel method, and their surfaces were coated with galactose. Characterization of these materials encompassed analysis of the particle size, specific surface area, microscopic morphology, and titanium ion release. Additionally, drug release profiles, particularly those of tadalafil, were investigated. assessments were conducted to evaluate the cytotoxic and mutagenic effects of the developed materials on CHO cells. The findings revealed a reduction in titanium ion release from the modified carrier compared to its unmodified counterpart. Pharmacokinetic studies in rats demonstrated enhanced absorption of the drug when the drug was delivered using the modified carrier. The synthesized materials exhibited high purity and favorable surface properties conducive to effective drug-carrier interactions. The results suggest that the modified titanium dioxide nanoparticles hold promise as efficient drug delivery vehicles in biomedical applications.

摘要

在当今医学中,进展往往取决于具有特殊性质的新产品。纳米技术专注于制造为满足特定治疗需求而量身定制的材料。本研究旨在阐明纳米颗粒,特别是二氧化钛纳米颗粒作为药物载体的潜力。为了减少载体表面潜在有害钛离子的释放,进行了改性处理。在初始阶段,基于溶胶 - 凝胶法获得二氧化钛纳米颗粒,并在其表面包覆半乳糖。对这些材料的表征包括粒径分析、比表面积分析、微观形态分析以及钛离子释放分析。此外,还研究了药物释放曲线,特别是他达拉非的释放曲线。进行了评估以评价所开发材料对CHO细胞的细胞毒性和致突变性。研究结果表明,与未改性的载体相比,改性载体的钛离子释放有所减少。在大鼠体内进行的药代动力学研究表明,当使用改性载体递送药物时,药物的吸收增强。合成材料具有高纯度和良好的表面性质,有利于有效的药物 - 载体相互作用。结果表明,改性二氧化钛纳米颗粒有望成为生物医学应用中高效的药物递送载体。
