[Study of the acute and chronic toxicity of a new preparation of the 3,5-dioxopyrazolidine series, butaglionamide, in comparison with amidopyrine and butadione].

An acute and chronic toxicity of butaglionamide, a new drug in the series of 3,5-dioxopyrazolidines, was contrasted against that of amidopyrine and butadion. The data obtained testify to a much lower toxicity of butaglionamide for rats of different age, both with a single and chronic administration.
