The invention discloses new addition salts of ziprasidone, namely sulfamates and N- substituted sulfamates in amorphous and crystal form and in the form of hydrates. The processes for their preparation comprise the reaction of 1 mol of ziprasidone base with 1 mol of sulfamic acids, and the method for the isolation of these salts in solid form. The invention further comprises a process for the preparation of granulate for tabletting and incapsulation, wherein ziprasidone salt finely distributed on an inert carrier is obtained. According to the invention, the new salts of ziprasidone are used for the treatment and prevention of psychotic disorders and diseases.
