Problems solved by technology

Another example: Some clinical research lacks reasonable scientific research design, such as lack of rigorous randomization, control, double-blind, small sample size, poor repeatability, and clinical efficacy needs to be further confirmed and improved; some clinical detection indicators are too simple
Another example: Some clinical treatments only stay in the dosage form of traditional Chinese medicine decoction, lack of necessary dosage form reform, and the research and development of new Chinese medicine is a relatively weak link

Abstract

The invention discloses a Chinese medicinal preparation for treating unstable angina pectoris and its preparation method. The preparation is prepared from Astragalus membranaceus, Ligusticum chuanxiong, Radix Puerariae, Ilex pubescens, and Herba Asari. Preparation method comprises extracting volatile oil from Ligusticum chuanxiong and Herba Asari, and collecting medicinal residue; diluting the volatile oil in anhydrous ethanol, dropping tobeta-cyclodextrin solution, stirring, and drying to obtain clathrate; extracting Astragalus membranaceus and Radix Puerariae with ethanol under reflux to obtain extractive liquid and collecting residue; mixing the above medicinal residues with Ilex pubescens, extracting with water, and concentrating the extractive liquid; mixing the above extractive liquids, concentrating to give soft extract, and making granule, pill, capsule or oral liquid with different adjuvants through conventional method. The inventive preparation is effective in dilating coronary artery, increasing coronary flow, improving blood supply to cardiac muscle, and reducing myocardial oxygen consumption.

Description

1. Technical field [0001] The invention relates to a traditional Chinese medicine preparation (named Ningxintong) and a preparation method, in particular to a Chinese medicinal preparation for treating unstable angina pectoris of coronary heart disease (chest pain and heart pain in traditional Chinese medicine) made from Chinese herbal medicines and a method for preparing the preparation method. 2. Background technology [0002] Unstable angina (UA) is a complex clinical syndrome between coronary heart disease between stable angina (SA) and acute myocardial infarction (AMI). According to the report "Nomenclature and Diagnostic Criteria of Ischemic Heart Disease" by the International Society of Cardiology and Associations and the World Health Organization (ISFC / WHO) Joint Task Force on Clinical Nomenclature Standardization, at present, initial exertional angina pectoris, worsening angina pectoris, spontaneous Chronic angina is collectively referred to as unstable angina. ...
