  • Crystalline composition containing escitalopram
    Publication number: 20050197388
    Abstract: The present invention discloses crystalline particles of escitalopram oxalate which either have a broad particle size distribution or comprise at least 0.01% (w/w) of Z-4-(4-dimethylamino-1-(4-fluorophenyl)-but-1-enyl)-3-hydroxymethyl-benzonitrile, said particles being suitable for use in direct compression. Furthermore, the invention discloses a novel pharmaceutical unit dosage form containing such crystalline particles of escitalopram oxalate as well as methods for manufacture of such crystalline particles of escitalopram oxalate Finally, the invention provides a method for reduction of the amount of hydroxyl containing impurities in a solution of citalopram or escitalopram.
    Type: Application
