<p>The present invention provides Crystalline ivabradine oxalate, optionally in a form characterized by at least one of the following:
a) power X-ray diffraction peaks at about 2.04, 2.13, 4.26, 7.06, 8.02, 8.53, 9.32, 10.91, 13.63, 15.07, 16.1 l, 16.44, 17.48, 18.37, 19.32,20.38, 20.94,21.95, 23.61, 24.26, 27.54 and 33.07 degrees 20; or
b) a differential scanning calorimetry thermogram, which shows one endothermic peak about 110°C.</p> |
