Benzoguanamine derivatives, their production and pharmaceutical compositions containing the same

Novel 2-amino-4-nicotinoylamino-6-halogenophenyl-s-triazines and acid addition salts thereof, possessing strong anti-inflammatory action when the phenyl group is mono- or di-halogen substituted. The compounds are formulated into pharmaceutical compositions in bulk or dosage form, and are administered to humans and animals having inflammatory conditions or disorders until the same are reduced or overcome. The novel compounds are prepared by various procedures such as reacting a benzoguanamine which is halogen-substituted with an active derivative of nicotinic acid, and recovering the 2-amino-4-nicotinoylamino-6-halogenophenyl-s-triazines thus formed.
