Abstract

The invention discloses a new crystal form omega-crystal form of ivabradine hydrochloride and preparation method thereof. The mixture of the ivabradine hydrochloride and water is heated and dissolved completely and then is frozen and dried to obtain delta-crystal form crystal. The crystal form has stable temperature and humidity, does not contain any organic solvent and moisture and is applicable to preparation technical process and a long period of storage. The medicine composite taking the crystal form composite as active ingredient can be used to treat or prevent angina, myocardial infarction and relative arhythmicity.

Description

technical field [0001] The present invention relates to omega-crystal form of ivabradine hydrochloride, its preparation method and pharmaceutical composition with the compound as active ingredient. Background technique [0002] The chemical name of ivabradine is 3-{3-[{[(7S)-3,4-dimethoxybicyclo[4.2.0]oct-1,3,5-trien-7-yl]- Methyl}(methyl)-amino]propyl}-7,8-dimethoxy-1,3,4,5-tetrahydro-2H-3-phenylacryrazine-2-one, Ivar The general formula (I) of Bradine hydrochloride (Ivabradine hydrochloride) is: [0003] [0004] Ivabradine hydrochloride has extremely valuable pharmacological and therapeutic properties, especially bradycardic properties, which make the compound useful in the treatment or prevention of various clinical conditions of myocardial ischemia such as angina pectoris, myocardial infarction and Associated arrhythmias, and various case conditions involving arrhythmias, especially supraventricular arrhythmias and heart failure. [0005] The preparation and thera...
