Abstract

The invention provides a drying method for tirofiban hydrochloride. A tirofiban hydrochloride wet product is subjected to fluidized drying through an efficient fluidized drying machine, wherein the drying temperature in the efficient fluidized drying machine is 40-50 DEG C, the drying time is 10-20 minutes, and the air flow is 30-70 m3/h. The tirofiban hydrochloride prepared through the drying method for the tirofiban hydrochloride is low in water content, is an off-white solid in appearance, meets the requirement for preparing a tirofiban hydrochloride sodium chloride injection, and has the advantages of being not likely to be caked and being low in impurity content.

Description

technical field [0001] The invention relates to the field of chemical pharmacy, in particular to a drying method for tirofiban hydrochloride. Background technique [0002] Tirofiban Hydrochloride, Tirofiban Hydrochloride, chemical name: N-(n-butylsulfonyl)-O-[4-(4-piperidinyl)butyl]-L-tyrosine hydrochloride monohydrate, Molecular formula: C 22 h 36 N 2 o 5 S·HCl·H 2 O, molecular weight 495.08. The product before the compound is salted - tirofiban is a non-peptide reversible antagonist of platelet glycoprotein Ⅱb / Ⅲa receptor, which can block the combination of fibrinogen and glycoprotein Ⅱb / Ⅲa Cross-linking of platelets and pharmacological activity of platelet aggregation. [0003] Tirofiban hydrochloride is suitable for patients with unstable angina or non-Q wave myocardial infarction. It can prevent cardiac ischemic events, and it is also suitable for patients with coronary ischemic syndrome undergoing coronary angioplasty or intracoronary atherectomy to prevent car...
