Summary
Torsemide and candesartan lower blood pressure additively and may cause hypotension or reduced renal function in volume-depleted patients. Candesartan lessens diuretic-induced potassium loss, but hyperkalemia can occur in renal impairment.
What this interaction means in plain words
Candesartan and Torsemide can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Candesartan belongs to Cardiovascular; Torsemide belongs to Cardiovascular.
Why it happens
Volume depletion plus angiotensin receptor blockade gives additive hypotension and reduced glomerular filtration; ARB lowers aldosterone-mediated potassium excretion.
What to do
Monitor blood pressure, creatinine and potassium after starting or changing either drug. Consider reducing the diuretic dose if the patient is volume depleted.
