<p>No drug interactions have been observed in studies of Azilsartan Medoxomil or Azilsartan given with amlodipine, antacids, chlorthalidone, digoxin, fluconazole, glyburide, ketoconazole, metformin, pioglitazone and warfarin. The antihypertensive effect of Azilsartan may be attenuated by the non-steroidal anti-inflammatory drugs including selective COX-2 inhibitors. Dual blockade of the RAS with angiotensin receptor blockers, ACE inhibitors or aliskiren is associated with increased risks of hypotension, hyperkalemia and changes in renal function.</p>
