[Comparative study on the saluretic activity of etacrynic acid and BAY g 2821 in patients with cardiac decompensation (author's transl)]. 1977

W Klein, and A Passath, and H Harpf, and J Dýcka

In a randomised double-blind comparative study 40 mg 3-amino-1-(3,4-dichloro-alpha-methyl-benzyl)-2-pyrazolin-5-one (BAY g 2821), a novel diuretic agent, were tested against 50 mg etacrynic acid in patients with cardiac decompensation. BAY g 2821 has a rapid onset of action which slowly decreases until 12 h after administration. Within a period between the second and the fourth hour after administration, the efficacy of BAY g 2821 is superior to that of etacrynic acid. The difference is statistically significant. The total elimination of BAY g 2821 is markedly more pronounced than that of etacrynic acid throughout the 5-day treatment course. Neither subjective nor objective side effects were observed.
