Abstract
Abstract—
Solid dispersions based on acyclovir and polysaccharides (starch and sodium carboxymethylcellulose) have been prepared by means of mechanochemistry. Mechanical co-processing of the drug and the polymers in a ball mill, an extruder, and a pulse mechanical action cell has led to amorphization of acyclovir, followed by its uniform distribution in the polymer matrix. A set of the IR and UV spectroscopy, DSC, and X-ray diffraction analysis data has revealed the presence of intermolecular interactions between the polysaccharide matrix and the drug. The obtained materials can be considered as potential system for further investigation as solid formulations of acyclovir with improved bioavailability.
摘要--通过机械化学方法制备了基于阿昔洛韦和多糖（淀粉和羧甲基纤维素钠）的固体分散体。在球磨机、挤压机和脉冲机械作用池中对药物和聚合物进行机械共处理后，阿昔洛韦发生了非晶化，随后均匀地分布在聚合物基质中。一组红外光谱、紫外光谱、DSC 和 X 射线衍射分析数据显示，多糖基质与药物之间存在分子间相互作用。所获得的材料可被视为具有进一步研究潜力的系统，作为阿昔洛韦的固体制剂，可提高其生物利用率。
