Summary

No clinically important effect on spironolactone absorption has been observed. The combination is often used deliberately to manage hyperkalemia and allow continued spironolactone therapy.
What this interaction means in plain words
Patiromer and Spironolactone 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
Theoretical binding of drug to the patiromer polymer in the gastrointestinal tract, which has not been shown to matter for spironolactone.
