Technique for preparing oral liquid for cough and asthma of children

Abstract

The invention relates to a preparation technique for children cough oral liquid, which comprises the following steps in turn: (1) extracting primary liquid medicine; (2) purifying the primary liquid medicine to obtain clear solution, and further condensing the clear solution to obtain extractum; and (3) preparing the liquid medicine by the extractum, flavoring and water, and then obtaining the children cough oral liquid after filtering and condensing the liquid medicine in turn, in particular, in step (2), the purifying means filtering the primary liquid medicine through an ultramicro filter film; and in step (3), the filtering is also carried out by the ultramicro filter film. Through adopting the ultramicro filter film to effectively filter the primary extracted liquid medicine, the preparation technique achieves non-alcoholization production, simplifies processes, shortens production period, and reduces energy consumption and production cost; and at the same time, through adopting a filtering technique of a tubular ultrafilter film to carry out terminal filter for the prepared liquid medicine, the preparation technique ensures the content of effective components, improves clarity of the liquid medicine, improves quality of products, and ensures quality stability of the products.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine pharmacy, in particular to the improvement of the preparation process of the children's Kechuanling oral liquid. Background technique [0002] Pediatric Kechuanling Oral Liquid is a traditional Chinese medicine liquid preparation refined from ephedra, gold and silver, bitter almonds, isatid root, gypsum, licorice, and Trichosanthes.

Problems solved by technology

However, in actual production, Chinese herbal medicines are bulky, consume a lot of ethanol, consume a lot, cost is high, and have a low boiling point, which is not conducive to safe production, poor safety, long cycle, high labor intensity, and poor production environment.

[0004] In addition, traditional talcum powder filter-aid plate frame filtration is generally used to filter and refine the traditional Chinese medicine liquid in the preparation process of Xiaoer Kechuanling Oral Liquid. Since this filtering method depends on the shape of the talc powder filter cake, when the amount of talc powder is not enough When it is suitable or improperly operated, the talcum powder filter cake will not be tight, which seriously affects the filtering effect of the liquid medicine, and the clarity of the liquid medicine cannot meet the requirements, so it is necessary to re-prepare the talc powder filter cake to repeatedly filter the liquid medicine, resulting in operating time Extended, the operation steps are cumbersome, and the product quality cannot be guaranteed
