Abstract

A δd-crystalline form of ivabradine hydrochloride of formula (I): characterised by its powder X-ray diffraction data. Medicinal products containing the same which are useful as bradycardics.

1 . A δd-Crystalline form of ivabradine hydrochloride of formula (I): 
       
         
           
           
               
               
           
         
       
     
     
         2 . The δd-Crystalline form of ivabradine hydrochloride of  claim 1  having a powder X-ray diffraction diagram exhibiting peaks at 14.6, 15.3, 17.2, 18.1 and 21.4 deg 2 theta. 
     
     
         3 . The δd-Crystalline form of ivabradine hydrochloride of  claim 1  having a powder X-ray diffraction diagram exhibiting peaks at 8.6, 9.1, 10.9 and 11.7 deg 2 theta. 
     
     
         4 . A pharmaceutical composition comprising as active ingredient the δd-crystalline form of ivabradine hydrochloride of  claim 1 , in combination with one or more pharmaceutically acceptable, inert, non-toxic carriers. 
     
     
         5 . A method for treating or preventing a condition requiring a bradycardic, such method comprising the step of administering to a living animal body, including a human, a therapeutically effective amount of the δd-crystalline form of ivabradine hydrochloride of  claim 1 . 
     
     
         6 . A method for treating or preventing clinical situations of myocardial ischaemia and/or a condition involving rhythm disturbances, such method comprising the step of administering to a living animal body, including a human, a therapeutically effective amount of the δd-crystalline form of ivabradine hydrochloride of  claim 1 . 
     
     
         7 . The method of  claim 6 , wherein the clinical situation of myocardial ischaemia is selected from angina pectoris, myocardial infarct and associated rhythm disturbances. 
     
     
         8 . The method of  claim 6 , wherein the condition involving rhythm disturbances is selected from supraventricular rhythm disturbances and heart failure.
