Problems solved by technology

However, DG is a weakly acidic drug, and its physical and chemical properties determine that it is easily soluble in water but not easily soluble in acidic solutions. Therefore, the capsule dissolves slowly and incompletely in the stomach, and enteric-coated tablets and enteric-coated capsules also have slow disintegration. The problem
[0004] Therefore, in the current DG preparations, enteric-coated tablets, enteric-coated capsules and capsules have poor absorption in the human body, low bioavailability, and the effect of protecting the liver and reducing enzymes is not very satisfactory (compared with its injections), and at the same time It is also difficult for people who have difficulty taking medicine, such as children and the elderly, to take it, which is very inconvenient

Abstract

he invention relates to a preparation method of a diammonium glycyrrhizinate lipid compound effervescent granule. The method provided by the invention aims to effectively improve the effect of drug absorption and bioavailability, in order to protect liver cytomembrane and improve liver function, and the effervescent granule has the characteristic of convenience. A technical scheme is as below: the preparation method of diammonium glycyrrhizinate lipid compound effervescent granule is carried out according to the following steps: 1) preparing a diammonium glycyrrhizinate lipid compound mixture; and 2) preparing the diammonium glycyrrhizinate lipid compound mixture into the diammonium glycyrrhizinate lipid compound effervescent granule by a wet granulation method. The preparation method of the diammonium glycyrrhizinate lipid compound comprises steps of: 1) preparing a soybean phospholipid tetrahydrofuran solution; 2) weighing a diammonium glycyrrhizinate extractive, conducting reflux dissolution, and when the solution is clear, taking out the solution for standing; and 3) preparing the diammonium glycyrrhizinate lipid compound. The preparation method of a sodium bicarbonate clathrate compound comprises steps of: 1) conducting clathration, and cooling to room temperature after uniform clathration; and 2) acquiring the sodium bicarbonate clathrate compound.

Description

technical field [0001] The invention relates to a preparation method of medicine, in particular to a preparation method of diammonium glycyrrhizinate lipid complex effervescent granules. Background technique [0002] Diammonium Glycyrrhizinate (DG) is an effective drug for the treatment of liver diseases. It can significantly reduce serum alanine aminotransferase and aspartate aminotransferase, protect liver cell membranes and improve liver function. Persistent hepatitis and chronic active hepatitis. [0003] The DG preparations currently on the market mainly include enteric-coated tablets, enteric-coated capsules and capsules (there is no significant difference in bioavailability among the three and are bioequivalent). If the drug dissolves quickly and stays in the stomach for a long time, the better the absorption effect of the drug and the higher the bioavailability. However, DG is a weakly acidic drug, and its physical and chemical properties determine that it is easil...
