Summary
Finerenone is a CYP3A4 substrate, and inhibition of CYP3A4 raises its exposure and the risk of hyperkalemia. Primaquine is not an established CYP3A4 inhibitor, so the interaction is largely theoretical.
What this interaction means in plain words
Finerenone and Primaquine have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Finerenone belongs to Cardiovascular; Primaquine belongs to Anti Parasitic.
Why it happens
Possible weak CYP3A4 inhibition by primaquine raising finerenone exposure; not firmly established.
What to do
Monitor serum potassium and renal function when primaquine is started during finerenone therapy and adjust the finerenone dose if hyperkalemia develops.
