FIELD: pharmaceutics.
SUBSTANCE: present invention relates to 2-iminobiotine pharmaceutical aqueous composition, having pH from 3 to 7 and containing 1 mg/ml or more of 2-iminobiotine and from 2.5 to 40 % of substituted beta-cyclodextrin, wherein said substituted beta-cyclodextrin is selected from sulfobutylether-beta-cyclodextrin (SBE-CD) and hydroxypropyl-beta-cyclodextrin.
EFFECT: invention provides creation of aqueous solution of 2-iminobiotine with high content of 2-iminobiotine (higher solubility of 2-iminobiotine), which is ensured by introduction of substituted beta-cyclodextrin into disclosed composition or citric acid/citrate buffer to ensure solution pH from 3 to 7.
