The aim of this study was to create nanoparticles of human serum albumin immobilized with anti-TB drugs (rifampicin, isoniazid) using the desolvation method. Central Composite Design (CCD) was applied to study the effect of albumin, urea, L-cysteine, rifampicin and isoniazid concentration on particle size, polydispersity and loading degree of the drugs. The optimized nanoparticles were spherical in shape with an average particle size of 216.7 ± 3.7 nm and polydispersity of 0.286 ± 4.9. The loading degree of rifampicin and isoniazid in the optimized nanoparticles were 44% and 27%, respectively. The obtained nanoparticles were examined by Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC); the results showed the absence of drug-polymer interactions. The drug release from the polymer matrix was studied using dialysis membranes.
本研究的目的是采用去溶剂化法制备固定有抗结核药物（利福平、异烟肼）的人血清白蛋白纳米颗粒。应用中心复合设计（CCD）研究白蛋白、尿素、L-半胱氨酸、利福平和异烟肼浓度对粒径、多分散性和药物负载度的影响。优化后的纳米颗粒呈球形，平均粒径为216.7±3.7nm，多分散性为0.286±4.9。优化后的纳米颗粒中利福平和异烟肼的负载度分别为44%和27%。通过傅里叶变换红外光谱（FTIR）、热重分析（TGA）和差示扫描量热法（DSC）对所得纳米颗粒进行了检测；结果表明不存在药物-聚合物相互作用。使用透析膜研究了药物从聚合物基质中的释放。
