描述 | Azosemide, a sulfonamide loop diuretic, was the most potent NKCC1 inhibitor (IC50s 0.246 µM for hNKCC1A and 0.197 µM for NKCC1B), being about 4-times more potent than bumetanide. Azosemide inhibits the sodium-potassium-chloride-cotransporter human variants hNKCC1A and hNKCC1B[3]. After oral administration of the same dose of azosemide and furosemide, the diuretic effect was similar between the two drugs, but after intravenous administration, the effect of azosemide was 5.5-8 times greater than that in furosemide[4]. Azosemide was absorbed from all regions of GI tract studied and approximately 93.5, 79.1, 86.1, and 71.5% of the doses (5, 10, 20, and 30 mg/kg, respectively) were absorbed between 1 and 24 hr after oral administration[5]. Azosemide is a new monosulfamyl diuretic which inhibits solute transport throughout the thick ascending limb of the loop of Henle. Azosemide 40 mg caused less potassium excretion than 40 mg of furosemide but there was no significant difference in the sodium/potassium excretion ratio[6]. |
