FIELD: medicinal agents. SUBSTANCE: isolation and purification of sodium nitroprusside is carried out by sodium nitroprusside dissolving in acidified water or aqueous-spirituous solution using tertiary aminoalcohols as stabilizing agent at concentration 0.5-1% Prepared solution is purified with activated carbon, and the following isolation of sodium nitroprusside is performed with low-molecular aliphatic alcohol. EFFECT: increased yield and quality of product.
