Renal
Diuretics that regulate fluid volume, electrolytes, and blood pressure by acting at specific points along the nephron. Learn them as a map of the tubule: where each acts sets its potency, its electrolyte fingerprint, and its dangers. (The Cardiovascular section covers diuretics from the heart-failure/blood-pressure angle — this section takes the renal view.)
Loop Diuretics
-semide High-yieldThe most powerful ("high-ceiling") diuretics — they work even in kidney failure. Watch potassium, volume, and hearing.
Thiazide Diuretics
High-yieldFirst-line for hypertension — a milder diuretic acting further down the nephron. Remember "hyperGLUC" and that they retain calcium (opposite of loops).
Potassium-Sparing Diuretics
High-yieldWeak diuretics that preserve potassium instead of wasting it — the defining danger is hyperkalemia. Two mechanisms; spironolactone also lowers heart-failure mortality.
Electrolyte & Fluid Replacement
High-yieldReplacing potassium, magnesium, calcium & fluids. IV potassium is high-alert — NEVER push it.
