Valsartan + Amlodipine Valsartan And Hydrochlorothiazide Interaction

Description

7 DRUG INTERACTIONS No drug interaction studies have been conducted with amlodipine/valsartan/hydrochlorothiazide and other drugs, although studies have been conducted with the individual components. A pharmacokinetic drug-drug interaction study has been conducted to address the potential for pharmacokinetic interaction between the triple combination, amlodipine/valsartan/hydrochlorothiazide, and the corresponding 3 double combinations. Valsartan Agents Increasing Serum Potassium: Concomitant use of valsartan with other agents that block the renin-angiotensin system, potassium-sparing diuretics (e.g., spironolactone, triamterene, amiloride), potassium supplements, salt substitutes containing potassium or other drugs that may increase potassium levels (e.g., heparin) may lead to increases in serum potassium and in heart failure patients to increases in serum creatinine.
