The solution relates to a method of preparation of an imatinib mesylate polymorph as an AP1 form suitable for dosage forms. Formation of new polymorphs of tyrosine kinase inhibitors proceeds depending on the conditions, said method consisting of the following steps: a) preparation of imatinib mesylate by reaction of the imalinib base and methanesulfonic acid in aqueous environment or in a water-organic solvent mixture, with optional addition of an organic solvent; b) addition of an inorganic salt in an aqueous solution, controlling the pH and ionic strength of the solution; c) crystallization process at controlled temperature. The solution also relates to the crystalline form of imatinib mesylate polymorph and use thereof. Two new polymorphous forms of Imatinib mesylate are accessible through this method, these forms are named polymorph "Z1" and "Z2". "Z1 " is characterized by peaks in the XRPD at 5,3; 7,5; 10,0; 10,6; 14,1; 15,0 and 16;6°. "Z2" is characterized by peaks in the XRPD at 5,5; 10,6; 10,9; 14.9; 17,0 and 21,9°.
