药物掩味技术及其味觉评价技术的研究进展

Research progress of taste masking and evaluation technology of medicine

  • 摘要: 多数药物味道苦涩、口感刺激,导致患者顺应性差,其不良气味严重影响药物治疗效率。一款药物的成功研发不仅应满足有效性、稳定性、安全性、均一性、经济性的五大质量特征,同时患者对不良气味药物的顺应性也不容忽视。味觉掩蔽技术针对不同性质药物进行掩味,其发展对改善药物口感具有重要意义。本文综述了传统掩味技术的原理及优缺点,并介绍了新型掩味技术如熔融制粒、热熔挤出、3D打印、药物复合物制备、苦味抑制剂的掩味机制和适用范围。针对药物掩味效果阐述体外评测方法如功能性磁共振成像、体外溶出、味觉指纹分析技术以及体内评测手段如动物、人体口尝在掩味效果领域的应用,并提出BP神经网络评价预测模型对药物口感评测的新策略,以期为今后药物掩味研究提供理论参考。

     

    Abstract: Most drugs taste bitter and irritating, resulting in poor compliance of patients, and the bad odor affects the therapeutic effect. The successful research and development of a drug should not only conform to the five quality characteristics of effectiveness, stability, safety, uniformity and economy, but also the compliance of patients to drugs with bad odor. The development of taste masking techniques is critical for bitter drugs.This review describes the principles, advantages and drawbacks of traditional taste masking techniques, and introduces the mechanism and application of novel taste masking techniques, such as melt granulation, hot melt extrusion, 3D printing, drug complex preparation, and bitter taste inhibitors. The in vitro evaluation methods of drug taste masking effect, such as functional magnetic resonance imaging, in vitro dissolution, and electronic tongue technology, are described. And introduce in vivo evaluation methods, such as animal and human taste, in the field of taste masking effect. A new strategy of BP neural network prediction model for drug taste evaluation is proposed, with a view to providing theoretical reference for the future research on drug taste masking.
