Bumetanide sodium, a highly potent loop diuretic, is a Na+-K+-Cl+ cotransporter (NKCC) blocker. Bumetanide sodium is a selective NKCC1 inhibitor, and also inhibits NKCC2, with IC50s of 0.68 and 4.0 μM for hNKCC1A and hNKCC2A, respectively[1][2]. | [in vivo]
Bumetanide sodium (7.6-30.4 mg/kg; i.v.) attenuates the decrease in apparent diffusion coefficients (ADC) ratios for both cortex and striatum (by 40-67%), indicating reduced edema formation[3].
Bumetanide sodium also reduces infarct size[3].
Bumetanide sodium shows different half-lives of 21.4 min, 53.8 min and 137 min following 2 mg/kg, 8 mg/kg and 20 mg/kg intravenous injection, respectively, in rats[4]. | [References]
