Renal and acid–base mnemonic

Segment sites of diuretic action

The mnemonic

Proximal Loops Distal Collect

What each word stands for

  • ProximalCarbonic anhydrase inhibitors (acetazolamide)
  • LoopsLoop diuretics block Na-K-2Cl in thick ascending limb
  • DistalThiazides block Na-Cl cotransporter in the DCT
  • CollectSpironolactone and amiloride act in the collecting duct

Why it matters clinically

Links each diuretic to its electrolyte pattern.

Where it stops being reliable

It orders sites only; electrolyte effects must be learned separately.
