Compounds of the class of acetals of 6-phenyl-4H-s-triazolo[4,3-a][1,4]benzodiazepine-1-carboxyaldehyde and the 5-oxides and pharmaceutically acceptable acid addition salts thereof have valuable pharmacological properties, in particular anticonvulsant effectiveness. Further, they show central depressant and muscle-relaxing activity and are active ingredients for therapeutic preparations. Specific embodiments are 6-phenyl-8-chloro-4H-s-triazolo[4,3-a][1,4]benzodiazepine-1-carboxalde hyde-diethylacetal, 6-(o-chlorophenyl)-8-chloro-4H-s-triazolo[4,3-a][1,4]benzodiazepine-1- carboxaldehydediethylacetal and 6-(o-fluorophenyl)-8-chloro-4H-s-triazolo [4,3-a][1,4]benzodiazepine-1-carboxaldehyde-diethylacetal. |
