Abstract
The invention comprises 1-phenyl-2-methyl-4-dimethylamino - 3, 6 - dioxo - 1, 2, 3, 6 - tetra - hydropyridazine, the preparation thereof by treating 1 - phenyl - 2 - methyl - 5 - bromo - 3, 6 - dioxo - 1, 2, 3, 6 - tetrahydropyridazine or 1 - phenyl - 2 - methyl - 4, 5 - dibromo - 3, 6 - dioxo-1,2,3,4,5,6-hexahydropyridazine with dimethylamine, and pharmaceutical preparations containing the product (see Group VI). Specification 880,016 also is referred to.ALSO:Pharmaceutical preparations for enteral, parenteral and topical administration and having antipyretic and analgesic activity, contain 1 - phenyl - 2 - methyl - 4 - dimethylamino - 3,6-dioxo - 1,2,3,6 - tetrahydropyridazine together with an inert pharmaceutical carrier. They may take the form of tablets, dragees, solutions, suspensions or emulsions, and may be sterilized and/or may contain preserving, stabilizing, wetting or emulsifying agents, salts for regulating the osmotic pressure, buffers, or additional therapeutically valuable substances. Specification 880,016 also is referred to.
