Ramipril, an ACE inhibitor, reduces lithium renal clearance through decreased glomerular filtration, leading to potentially toxic lithium accumulation.

Combining empagliflozin with an ACE inhibitor such as ramipril can cause additive blood pressure reduction and volume depletion, increasing the risk of hypotension and acute kidney injury.
