  • This increases the delivery of sodium potassium and chloride to the distal nephron. (derangedphysiology.com)
  • Because of the main site of sodium reabsorption being the proximal tubule, theoretically only up to 20% of filtered sodium can be excreted by the blockade of all NKCC2 channels, which means loop diuretic therapy has a ceiling effect. (derangedphysiology.com)
