   2-[(5methoxy-1H-indol-3-yl)methylene]-N- pentylhydrazinecarboximidamide hydrogen maleate commercial tablet contains form A It was found by X-Ray powder diffraction analysis that the commercial tablet ZELNORM of 2-[(5methoxy-1H-indol-3-yl)methylene]-N- pentylhydrazinecarboximidamide hydrogen maleate contains 2-[(5methoxy-1H-indol- 3-yl)methylene]-N-pentylhydrazinecarboximidamide hydrogen maleate crystal form denominated form A.

The attached figure shows the X-Ray patterns of 2-[(5methoxy-1H-indol-3- yl)methylene]-N-pentylhydrazinecarboximidamide hydrogen maleate form A, the commercial tablet, and lactose hydrous. The peaks of 2-[(5methoxy-1H-indol-3- yl)methylene]-N-pentylhydrazinecarboximidamide hydrogen maleate form A are clearly seen at 5.4, 6.0, 6.6, 10.8 degrees two-theta.
