Abstract

The invention provides an echinacoside preparation. Raw materials of the echinacoside preparation comprise the following components in parts by weight of 5-58 parts of echinacoside; 32-84 parts by weight of a filler; 5-12 parts by weight of a disintegrating agent; 0-5 parts by weight of an adhesive; 0.1 to 2 parts by weight of a lubricant, wherein the filler comprises pregelatinized starch. According to the echinacoside preparation, the pregelatinized starch is used as the filler and is matched with the disintegrating agent, adhesive and lubricant, so that the finally obtained echinacoside tablet is smooth in surface, proper in thickness and hardness, qualified in friability and good in dissolution rate.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to an echinacoside preparation and a preparation method thereof. Background technique [0002] During the use of drugs, in order to meet the needs of different drug routes, drug effects, and drug users, it is necessary to make drugs into different dosage forms, such as tablets, pills, injections, aerosols, ointments, etc. Through the study of pharmacy, various biological drugs, chemical raw materials, and traditional Chinese medicine extracts have been made into drugs that can be directly used in the human body, which not only ensures the efficacy of drugs, but also improves the absorption and utilization of drugs. Due to the effectiveness, stability, uniformity, and economical properties of pharmaceutical preparations, it not only ensures the convenience of medication for patients, but also ensures the controllability of drug quality and reduces the risk of drug...
