Abstract

The invention relates to a tirofiban hydrochloride lyophilized powder injection and a preparation method thereof, belonging to the field of western medicine preparation. The tirofiban hydrochloride lyophilized powder injection contains 1 part by weight of tirofiban hydrochloride and 0.5-100 parts by weight of dextran, and the pH value of solution before lyophilization is 1.8-2.6. Preferably, the weight ratio between the dextran and the tirofiban hydrochloride is 2:1-20:1. The tirofiban hydrochloride lyophilized powder injection has good composite dissolubility and stability as well as high safety.

Description

technical field [0001] The invention relates to a tirofiban hydrochloride freeze-dried powder injection and a preparation method, belonging to the field of western medicine preparations. Background technique [0002] Tirofiban is used for patients with unstable angina, non-Q wave myocardial infarction, and patients undergoing coronary angioplasty or intracoronary atherectomy. The currently marketed dosage form is isotonic sodium chloride. Regulators, citric acid buffer salts as pH regulators for concentrated solutions for injection and large infusions have disadvantages such as poor stability, unstable pH value, and insoluble particles in the solution during storage, which brings great harm to the patient's medication safety. hidden danger, and the volume and weight of the injection are relatively large, making transportation and storage inconvenient. In the production process of freeze-dried powder injection, the medicine is freeze-dried under low temperature and near vacu...
