Summary
Nonselective beta-blockers can modestly raise serum potassium by impairing cellular potassium uptake, which may add to the potassium-raising effect of drospirenone. The effect is generally small in patients with normal renal function.
What this interaction means in plain words
Drospirenone and Penbutolol have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Additive potassium elevation from aldosterone antagonism and beta-blockade reducing cellular potassium uptake.
What to do
Routine monitoring is usually sufficient; check potassium in patients with renal impairment or on other potassium-raising drugs.
