Moisture absorption is one of the main reasons leading to the instability of solid preparations of traditional Chinese medicine. The main factors influencing its absorption of moisture include the property of the Chinese medicine, the constitutions of the formulation, the extraction and purification processes, package and storage. Moisture-proof technology is summarized in this review by analysis of the parameters of the mathematical model so as to provide the evidence for moisture-proof of the solid preparations of traditional Chinese medicine.% 吸湿是导致中成药固体制剂质量和疗效不稳定主要原因之一,而中药成分的性质、提取纯化工艺、处方组成、包装和贮藏条件是造成中成药固体制剂吸潮的主要因素。本文应用数学模型参数总结现有的防潮技术,为中成药固体制剂防潮提供依据。
