Abstract

The invention discloses a method for preparing changyanning granules, which comprises the following steps: weighing the following raw materials in parts by weight: 5-10 parts of heba euphorbiae humifusae, 8-10 parts of goldhair hedyotis herb, 5-10 parts of camphor tree root, 2-4 parts of elsholtzia ciliata, 2-4 parts of maple tree leaf, 0.2-0.5 part of dextrin and 0.5-0.8 part of lactose; preparing an extract after leaching the five traditional Chinese medicinal materials by water and alcohol, preparing medicinal powder after mixing, spraying and drying the extract and a right amount of dextrin, mixing the medicinal powder and the remanent auxiliary materials thrice and preparing the changyanning granules by granulating in a dry method. The changyanning granules prepared by the method havestable, controllable and uniform quality, simple operation, short production period, no need of special equipment, low cost and high yield and are suitable for industrialized production.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to a preparation method of Changyanning Granules. Background technique [0002] Existing Changyanning preparations are generally made from the five flavors of traditional Chinese medicines such as Dijincao, Pleurotus chinensis, camphor tree root, fenugreek and maple leaves. Diseases, dyspepsia in children, is currently one of the most commonly used gastrointestinal drugs. [0003] Most of the preparations of Changyanning are based on the quality standard of Changyanning syrup (WS 3 The syrup prepared by -B-3597-98) has high sugar content, which is unfavorable for diabetics to take, large volume, inconvenient transportation and storage, and easy mildew and other shortcomings. If it is made into granules, it is beneficial to divide doses, it is convenient to take, easy to transport and store, and it is made into solid preparations, which improves the stability of the drug....
