Abstract:
The preparation of Calculus bovis and its compounding preparations have been used widely in clinical practice.Traditionally,the forms of medicine were in raw material medicine way,preparing tablet,pill,powder or directly taking its powder.The main active ingredient of Calculus bovi were considered to be bilirubin and bile acids.However,the traditional formulations caused low bioavailability and wasted expensive herbs because its main component were insoluble in water.In recent years,many researchers have tried to use modern preparation technology to prepare its compounding formulations,such as solid dispersion technology,ultrafine grinding technology,powder coating technology,liposome encapsulation technology,or simplifying the prescription by using of known pharmacological effects of soluble components as substitutes.These methods were considered to be feasible to develop new formulations of Calculus bovis.In this paper,in order to provide reference of method and technology for the improvement of Calculus bovis compounding preparation and the development of new dosage form,ultramicrostructure,chemical composition,improvement methods and techniques of compounding preparation were analyzed.In addition,the relevant techniques and method of improving the formulation Calculus bovis compounding preparation in recent years were reviewed.
