[Application regularity and solution strategies of mineral medicine Cinnabaris in pediatric preparations]

Mineral medicine is a characteristic element of advantage of traditional Chinese medicine(TCM), which embodies unique scientific connotation. Cinnabaris is a characteristic drug in Chinese medicinal preparations, especially in Chinese medicinal pediatric preparations. Because of the adverse reactions caused by mercury contained, the safety and application of Cinnabaris have attracted much attention. To explore the application regularity and the value of the pediatric preparations containing Cinnabaris, this study statistically analyzed 32 Cinnabaris-contained pediatric preparations in the 2020 edition of the Chinese Pharmacopoeia and 105 pediatric preparations containing Cinnabaris in the Dictionary of Traditional Chinese Medicine Prescriptions(Vol. Ⅰ and Ⅱ). The statistical results indicated that the pediatric preparations and formulae containing Cinnabaris had great advantages in the treatment of pediatric convulsions, but there were still problems in dosage form, dosage, and quality control. In this study, ICP-MS and LC-AFS were further used to determine the content of total mercury and soluble mercury in 15 commercially available pediatric preparations containing Cinnabaris. It was found that the total mercury content was far higher than soluble mercury content in the sample preparations, and there was no obvious correlation between them. According to the results, the research and application strategies of Cinnabaris were put forward in order to provide references for the rational application of Cinnabaris in pediatric preparations.
