Dose-equivalence by class

Loop diuretic equivalent-dose calculator

Equivalence chart

Each loop diuretic expressed as the dose equivalent to Furosemide 40 mg by relative INTRAVENOUS potency, from a peer-reviewed table. The ratio is IV potency, not oral bioequivalence — furosemide oral bioavailability is wide and variable. Educational, not a prescription.

Loop diuretic equivalent doses express furosemide, torasemide and bumetanide on a furosemide-equivalent scale from a peer-reviewed relative-intravenous-potency table (furosemide 40 mg ≈ torasemide 20 mg ≈ bumetanide 1 mg); the ratio is intravenous potency and oral bioavailability differs, so it is an educational estimate, not a proven oral bioequivalence or a prescription.
