Summary

Both sirolimus and ACE inhibitors are associated with angioedema, and combined use increases that risk. Swelling of the face, lips or airway can be life-threatening.

What this interaction means in plain words

Quinapril and Sirolimus can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Evidence level: Moderate

Why it happens

Additive angioedema risk, possibly through impaired bradykinin degradation by ACE inhibition combined with mTOR inhibitor effects.

What to do

Consider an alternative antihypertensive such as a calcium channel blocker, or an ARB with caution. Counsel patients to seek urgent care for swelling and stop the ACE inhibitor if angioedema occurs.

What to ask your pharmacist

  • Does the benefit of taking both outweigh the risk in my case?
