Abstract

The invention relates to injection containing tirofiban hydrochloride and belongs to the field of pharmaceutical preparations. The injection consists of 0.05 to 0.5 percent (w / v) of tirofiban hydrochloride, 5 to 25 percent (v / v) of 1,2-propylene glycol, 5 to 25 percent(v / v) of ethanol and water, and the pH value of the injection is 3.5 to 6.5. When the injection containing the tirofiban hydrochloride is clinically used, the transfusion volume of a patient is lowered, and the injection can also be added in sodium chloride or glucose transfusion for intravenous drip of the patient, so that the patients suitable to be treated by the injection is increased, and the injection is suitable for more patients suffering from acute coronary syndromes.

Description

technical field [0001] The invention relates to a tirofiban hydrochloride injection, which belongs to the field of pharmaceutical preparations. Background technique [0002] Tirofiban is a non-peptide platelet membrane glycoprotein IIb / IIIa (GP IIb / IIIa) receptor antagonist, which has the effect of blocking platelet cross-linking and platelet aggregation. Its chemical name is (S)-N-(n-butylsulfonyl-O[4-(4-piperidinyl)butyl]-L-tyrosine, and its hydrochloride-hydrate is generally used in medicine. [0003] Tirofiban hydrochloride inhibits the binding of fibrinogen to platelet membrane G PIIb / IIIa receptors, thereby blocking platelet cross-linking and platelet aggregation. It is clinically used to treat patients with acute coronary syndrome (ACS), and it is also suitable for patients with acute coronary syndrome to undergo coronary angioplasty or intracoronary plaque resection, which can reduce death, myocardial infarction, and refractory Incidence of the composite endpoint o...
