Abstract
The present invention relates to a process for the preparation of amorphous carvedilol phosphate comprising; adding carvedilol base or carvedilol phosphate to a solvent consisting of water miscible cyclic ether(s) or aliphatic nitrile(s) or a mixture thereof and optionally adding water; optionally, adding orthophosphoric acid or its diluted solution to the preceeding; and spray drying the solution thus obtained to afford amorphous carvedilol phosphate.
