Controlled drug delivery is a key strategy aimed at reducing both the frequency of therapeutic dosages and potential systemic side effects, particularly in the case of high drug concentrations. The nanocomposite hydrogel systems presented in this study were synthesized by combining carboxymethyl cellulose, polyvinyl alcohol, and (3-aminopropyl)triethoxysilane-functionalized halloysite nanotubes (fHNTs). This hydrogel system is a potential candidate for the controlled release of cefadroxil monohydrate. These hydrogels are analyzed by Fourier transform infrared spectroscopy, scanning electron microscopy, thermogravimetric analysis, and rheological measurements. Additionally, swelling properties, porosity, hydrophilicity, drug release, and in vitro and in vivo analyses were also evaluated. The observed trends in swelling and drug release demonstrated that the outcomes are dependent on the presence of fHNTs in the hydrogel matrix. Notably, fHNTs-loaded hydrogels displayed sustained drug release patterns. This innovative approach eliminates the need for traditional encapsulation and presents promising and translatable strategies for achieving more effective drug release.
控释给药是一种关键策略,旨在减少治疗剂量的给药频率以及潜在的全身副作用,尤其是在药物浓度较高的情况下。本研究中呈现的纳米复合水凝胶体系是通过将羧甲基纤维素、聚乙烯醇和(3-氨丙基)三乙氧基硅烷功能化的埃洛石纳米管(fHNTs)相结合而合成的。这种水凝胶体系是一水头孢羟氨苄控释的潜在候选材料。通过傅里叶变换红外光谱、扫描电子显微镜、热重分析和流变学测量对这些水凝胶进行了分析。此外,还评估了溶胀性能、孔隙率、亲水性、药物释放以及体外和体内分析。观察到的溶胀和药物释放趋势表明,结果取决于水凝胶基质中fHNTs的存在。值得注意的是,负载fHNTs的水凝胶呈现出持续的药物释放模式。这种创新方法无需传统的包封,并为实现更有效的药物释放提供了有前景且可转化的策略。
