title: Diuretic effect of ITA 529.
abstract: The diuretic and saluretic activity of ITA 529 (Ethyl-beta-[(5-tert-butyl-3-chloro-2-hydroxy)benzylamino]crotonate++ +) in rat, rabbit and monkey is described in this study. In rat, the diuretic ED50 of ITA 529 was 1.23 mg/kg p.o. and its ED100 1.69 mg/kg p.o. The diuretic ED50 of furosemide was 18.48 mg/kg p.o. and its ED100 22.38 mg/kg p.o. Their effect lasted approximately 3 hours. In monkey, the diuretic ED50 of ITA 529 was 2.29 mg/kg p.o. and its ED100 6.54 mg/kg p.o. while for furosemide its ED50 was 2.44 mg/kg p.o. and its ED100 5.72 mg/kg p.o. In rabbit the ED50 of ITA 529 was 1.83 mg/kg p.o. and its ED100 3.37 mg/kg p.o. For furosemide, its ED50 was 2.25 mg/kg p.o. and its ED100 7.13 mg/kg p.o. The natriuretic activity of ITA 529 was reduced by indomethacin.
