Abstract
The form B of paroxetine maleate polymorph is characterized by determined data of X ray diffraction: it has a chemical stability which is superior to that of the form A of paroxetine maleate. This superior stability enables to use the new polymorph for the fabrication of medicaments intended to the treatment of troubles related to dysfunctions of the central nervous system. The process for producing the paroxetine maleate comprises the preparation of paroxetine maleate solution and a consequent precipitation.
