Risk of angioedema may be increased w/ ACE inhibitors. Higher frequency of adverse events (eg, hypotension, hyperkalemia & decreased renal function including acute renal failure) w/ aliskiren. May increase systemic exposure of OATP1B1 & OATP1B3 substrates eg, statins. Increased C
max & AUC of atorvastatin. Greater BP reduction w/ PDE5 inhibitors (eg, sildenafil) compared to Entresto alone. May lead to increases in serum K & creatinine w/ K-sparing diuretics (triamterene, amiloride), mineralocorticoid antagonists (spironolactone, eplerenone), K supplements, K-containing salt substitutes or other agents (eg, heparin). May lead to increased risk of worsening renal function w/ NSAIDs including selective COX-2 inhibitors in elderly patients, vol-depleted patients (including those on diuretic therapy), or those w/ compromised renal function. Reversible increases in serum lithium conc & toxicity. Reduced C
max & AUC of furosemide; metformin. Concomitant use w/ nitrates eg, nitroglycerine. Systemic exposure of sacubitril/valsartan may be increased w/ OATP1B1, OATP1B3, OAT3 (eg, rifampicin, ciclosporin), OAT1 (eg, tenofovir, cidofovir) or MRP2 (eg, ritonavir) inhibitors.
