Abstract:This paper aims to reveal the existing problems of uniformity of Chinese materia medica solid preparation,discuss the causes and impact of problems,and provide the reference for consistency of the drug production.Through searching the literature reports about uniformity of solid preparations of Chinese medicine in the recent ten years,the problem of uniformity of Chinese materia medica solid preparation from the three aspects in physics,chemistry and biological effects were discussed,the causes of poor uniformity of solid preparation were discussed,the effect of effectiveness,safety and controllability of solid preparation that caused by ununiformity of solid were analysed.There were difference among solid preparations in physics,chemistry and biological effects,which mainly caused by the difference of production technics.Drug efficacy and safety were affeced by uniformity problems of solid preparation,and insiders should pay more attention to this problem.
