FIELD: pharmaceutics.
SUBSTANCE: group of inventions relates to pharmaceutics, namely to a pharmaceutical composition for oral administration of enzalutamide and a method for preparing it. Pharmaceutical composition for oral administration of enzalutamide includes enzalutamide and polyvinyl alcohol, where polyvinyl alcohol has a degree of saponification from 63 mol.% to 85 mol.%, and a degree of polymerisation from 100 to 500, where the content of polyvinyl alcohol ranges from 50 wt.% to 500 wt.% with respect to the weight of enzalutamide, and further includes potassium chloride, sodium chloride or potassium dihydrophosphate as a co-disintegrant. Method of producing said pharmaceutical composition involves a step for preparing a solid dispersion containing enzalutamide and polyvinyl alcohol.
EFFECT: obtained pharmaceutical composition has improved solubility, increased bioavailability and rate of absorption of enzalutamide.
