FIELD: chemistry.
SUBSTANCE: as medications composition includes beclomethazone dipropionate and salbutamol, with beta-glycine serving as carrier. Composition is obtained by dispersing solutions of initial medications in mixed solvent into tank with liquid nitrogen with further removal of solvents from obtained by dispersion mixture solid phases in dry nitrogen flow under pressure 600±20 mtorr to pressure drop less than 8 mtorr with stopping nitrogen supply by step-by-step increase of temperature: in the interval from -196°C to -15°C, then from -15°C to +30°C. As initial substances used are: beclomethazone dipropionate 1.9-5.1 wt %, salbutamol 1.9-10.2 wt %, alpha-glycin to 100%. Composition of mixed solvent includes tetrahydrofurane 5-15 wt %, tert-butyl alcohol 15-5 wt %, water 77-80 wt %.
EFFECT: invention provides obtaining highly dispersed pharmaceutical composition of salbutamol and beclomethazone dipropionate.
