<p>No drug interactions of clinical significance have been found. Compounds which have been studied in clinical trials include Cimetidine, Warfarin, Furosemide, Digoxin, Atenolol, Indomethacin, Hydrochlorothiazide, Amlodipine and Glibenclamide<br />

As Valsartan&nbsp;is not metabolized to a significant extent, clinically relevant drug-drug interactions in the form of metabolic induction or inhibition of the cytochrome P450 system are not expected with Valsartan. Although valsartan is highly bound to plasma proteins, in vitrostudies have not shown any interaction at this level with a range of molecules which are also highly protein bound, such as Diclofenac, Furosemide, and Warfarin. Concomitant use of potassium sparing diuretics (e.g., Spironolactone, Triamterene, Amiloride) potassium supplements, or salt substitutes containing potassium may lead to increase in serum potassium. If co medication is considered necessary, caution is advisable.</p>
