Potentiated by CYP3A4 inhibitors; may need dose reduction. Antagonized by NSAIDs (including selective COX-2 inhibitors); may impair renal function (monitor). Dual inhibition of the renin-angiotensin system with ARBs, ACEIs, or aliskiren may increase risk of hypotension, hyperkalemia, renal function changes; monitor closely.
