Summary
Combining a beta-blocker with an ARB is common and gives additive blood pressure reduction, with possible hypotension or bradycardia. Beta-blockers can modestly raise potassium, and ARBs add to this. Both classes carry fetal risk in pregnancy, but that stems from the ARB rather than the combination.
What this interaction means in plain words
Candesartan and Nadolol 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; Nadolol belongs to Cardiovascular.
Why it happens
Additive antihypertensive effect; beta-blockade impairs cellular potassium uptake while the ARB reduces aldosterone-mediated potassium excretion.
What to do
Monitor blood pressure, heart rate and potassium, particularly with renal impairment. Avoid candesartan in pregnancy.
