Higher frequency of adverse events (eg, hypotension, hyperkalaemia & decreased renal function including acute renal failure) associated w/ dual blockade of the RAAS through combination w/ ARBs or aliskiren. May increase risk of angioedema w/ racecadotril, mTOR inhibitors (eg, sirolimus, everolimus, temsirolimus) & gliptins (eg, linagliptin, saxagliptin, sitagliptin, vildagliptin). May increase occurrence of hyperkalaemia w/ aliskiren, K salts, K-sparing diuretics (eg, spironolactone, triamterene or amiloride), ACE inhibitors, AIIAs, NSAIDs, heparins, immunosuppressants (eg, ciclosporin or tacrolimus), trimethoprim & co-trimoxazole. Increased risk of hyperkalaemia, worsening of renal function & CV morbidity & mortality w/ aliskiren in diabetic or impaired renal patients. Increased risk of severe anaphylactoid reactions w/ extracorporeal treatments. Avoid use w/ lithium; K-sparing drugs (eg, triamterene, amiloride), K supplements or K-containing salt substitutes, other drugs which can increase K in the body (eg, heparin, co-trimoxazole); dantrolene (infusion); medicines most often used for diarrhea (eg, racecadotril) or to avoid rejection of transplanted organs (eg, sirolimus, everolimus, temsirolimus & other mTOR inhibitors); sacubitril/valsartan; other medicines for high BP eg, ACE inhibitor & ARBs. Caution in use w/ ARB, aliskiren, or diuretics; K-sparing diuretics for heart failure eg, eplerenone & spironolactone; anesth; iodinated contrast agent; bepridil; methadone; medicines for heart rhythm problems eg, dofetilide, ibutilide, bretylium, cisapride, diphemanil, procainamide, quinidine, hydroquinidine, disopyramide, amiodarone, sotalol; verapamil, diltiazem; digoxin or other cardiac glycosides; antibiotics for bacterial infections eg, rifampicin, erythromycin, clarithromycin, sparfloxacin, moxifloxacin; antifungals eg, itraconazole, ketoconazole, amphotericin B (inj); allopurinol; antihistamines for allergic reactions eg, hay fever (eg, mizolastine, terfenadine, astemizole); corticosteroids for severe asthma & RA, & NSAIDs (eg, ibuprofen) or high-dose salicylates (eg, ASA); immunosuppressants eg, ciclosporin, tacrolimus; tetracosactide; gold salts (especially IV); halofantrine; baclofen; medicines for diabetes eg, insulin or metformin; Ca including Ca supplements; stimulant laxatives eg, senna; medicines for cancer; vincamine; medicines for mental disorders eg, TCAs, antipsychotics, imipramine-like antidepressants, neuroleptics (eg, amisulpride, sulpride, sultopride, tiapride, haloperidol, droperidol); pentamidine; ritonavir, indinavir, nelfinavir;
Hypericum perforatum; trimethoprim; medicines for low BP, shock or asthma eg, ephedrine, noradrenaline or adrenaline; nitroglycerin & other nitrates, or other vasodilators that may further reduce BP. Increased blood levels of amlodipine which can increase BP-lowering effect w/ grapefruit juice & grapefruit.
