FIELD: medicine, hematology, pharmacy.

SUBSTANCE: invention relates to the composition of factor VIII composed without addition of albumin and comprising the following excipients of composition in addition to factor VIII: from 4% to 10% of filling agent taken among group consisting of mannitol, glycine and alanine; from 1% to 4% of stabilizing agent taken among group consisting of sucrose, trehalose, raffinose, arginine; from 1 mM to 5 mM of calcium salt, from 100 mM to 300 mM of NaCl, and buffer agent for pH value maintenance about between 6 and 8. Alternatively, the composition can comprise from 2% to 6% of hydroxyethylstarch; from 1% to 4% of stabilizing agent taken among group consisting of sucrose, trehalose, raffinose, arginine; from 1 mM to 5 mM of calcium salt, from 100 mM to 300 mM of NaCl, and buffer agent for pH value maintenance between 6 and 8. In additional variant of realization of invention the composition can comprise: from 300 mM to 500 mM of NaCl, from 1% to 4% of stabilizing agent taken among group consisting of sucrose, trehalose, raffinose and arginine; from 1 mM to 5 mM of calcium salt, and buffer agent. The composition provides stability in the absence of albumin or other proteins.

EFFECT: valuable properties of compositions.
