Summary
Drospirenone has antimineralocorticoid activity and can raise serum potassium. Combined with an ACE inhibitor, hyperkalemia risk increases, particularly with renal impairment.
What this interaction means in plain words
Drospirenone and Fosinopril 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.
Drospirenone belongs to Endocrine; Fosinopril belongs to Cardiovascular.
Why it happens
Additive potassium retention from aldosterone antagonism by drospirenone and reduced aldosterone production through ACE inhibition.
