    摘要: A stable pharmaceutical aqueous solution of cyanocobalamin comprised of cyanocobalamin and water wherein said solution of cyanocobalamin is suitable for intranasal administration, has a viscosity less than about 1000 cPs, and yields a bioavailability of cyanocobalamin when administered intranasally of at least about 5% relative to an intramuscular injection of cyanocobalamin. The present invention is also directed towards a method for elevating the vitamin B 12 levels in the cerebral spinal fluid (CSF) comprising administering intranasally a sufficient amount of a cyanocobalamin solution so as to increase the average ratio of vitamin B 12 in the CSF to that in the blood serum (B12 CSF/B12 Serum x 100) to at least about 1.1 comprising intranasally administering an aqueous solution of a cyanocobalamin, wherein said solution of cyanocobalamin has a bioavailability of at least 5% relative to an intramuscular injection of a cyanocobalamin.

    摘要: 57 A process for the separation of vitamin B 12 in pure form which comprises bringing a vitamin B 12 -containing liquid having impurities into contact with a divinylbenzene styrene copolymer resin, and causing vitamin B 12 to be adsorbed to the resin. The vitamin B 12 thus adsorbed is eluted an eluent which is an aqueous solution containing a compound selected from the group consisting of a lower ketone, a lower ester and a lower ether. The resin may be treated before elution with purified water or an aqueous low-acidity solution.
