Abstract

The present invention relates to medicine preparation technology, and is one kind of orally disintegrated sodium ferulate tablet for treating coronary heart disease, cerebral vascular diseases, angeitis and other diseases and its preparation process. The orally disintegrated sodium ferulate tablet consists of sodium ferulate as active component in 10-50 wt% and pharmaceutically acceptable supplementary material including disintegrating agent, stuffing, adhesive, lubricant and corrective in 50-90 wt%. It may be prepared through freeze drying process, direct powder tabletting process or wet tabletting process with different supplementary material being selected. The orally disintegrated sodium ferulate tablet has fast leaching, easy swallowing and other advantages, and is especially suitable for old patients with dysphagia.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, and relates to a sodium ferulate orally disintegrating tablet and a preparation method thereof. Background technique [0002] Sodium ferulate (sodium ferulate) is the sodium salt of ferulic acid, the main component of traditional Chinese medicine extracts such as angelica and chuanxiong. disease treatment. The curative effect is definite, and its marketed oral dosage form is common tablet. However, sodium ferulate tablets are insoluble in the stomach. According to the dissolution test of sodium ferulate tablets in the 2005 edition of "Chinese Pharmacopoeia", it is found that commercially available sodium ferulate tablets (Chengdu Hengda Pharmaceutical Co., Ltd., batch number 040804) Only 10% of the drug dose is dissolved in the artificial gastric juice in 45 minutes, which affects the absorption of the drug in the body, and the drug takes effect slowl...
