Filing Date: | Oct 21, 2009 |
Application Number: | 12/589,283 |
Claims: | 1. A .beta.-Crystalline form of ivabradine hydrochloride of formula (I): ##STR00003## having a powder X-ray diffraction diagram exhibiting peaks at 9.2, 18.4, 19.7, 21.6 and 25.3 deg 2 theta. 2. A .beta.-Crystalline form of ivabradine hydrochloride of formula (I): ##STR00004## having a powder X-ray diffraction diagram exhibiting peaks at 9.2, 9.7, 10.0 and 14.8 deg 2 theta. 3. A solid pharmaceutical composition comprising as active ingredient the .beta.-crystalline form of ivabradine hydrochloride of claim 1, in combination with one or more pharmaceutically acceptable, inert, non-toxic carriers. 4. A method for treating a condition selected from angina pectoris, myocardial infarct, and heart failure, such method comprising administering to a human, a therapeutically effective amount of the .beta.-crystalline form of ivabradine hydrochloride of claim 1. 5. A solid pharmaceutical composition comprising as active ingredient the .beta.-crystalline form of ivabradine hydrochloride of claim 2, in combination with one or more pharmaceutically acceptable, inert, non-toxic carriers. 6. A method for treating a condition selected from angina pectoris, myocardial infarct, and heart failure, such method comprising administering to a human, a therapeutically effective amount of the .beta.-crystalline form of ivabradine hydrochloride of claim 2. |
