Spironolakton i Triamteren + hydrochlorotiazyd: interakcja

CONTRAINDICATIONS Antikaliuretic Therapy and Potassium Supplementation Triamterene and hydrochlorothiazide should not be given to patients receiving other potassium-sparing agents such as spironolactone, amiloride, or other formulations containing triamterene.

Thiazides may add to or potentiate the action of other antihypertensive drugs.

See INDICATIONS AND USAGE for concomitant use with other antihypertensive drugs.

This risk is increased by impaired renal function or concomitant potassium supplementation, potassium-containing salt substitutes or drugs that increase potassium, such as angiotensin converting enzyme inhibitors and angiotensin receptor blockers [see Drug Interactions ( 7.1 )] .

NSAIDs: May reduce the diuretic, natriuretic and antihypertensive effect of spironolactone oral suspension ( 7.3 )

…drugs that can increase potassium include: ACE inhibitors angiotensin receptor blockers aldosterone blockers non-steroidal anti-inflammatory drugs (NSAIDs) heparin and low molecular weight heparin trimethoprim 7.2 Lithium Like other diuretics, spironolactone oral suspension reduces the renal clearance of lithium, thus increasing the risk of lithium toxicity.

Nonsteroidal Anti-inflammatory Drugs (NSAIDs) In some patients, the administration of an NSAID can reduce the diuretic, natriuretic, and antihypertensive effect of loop, potassium-sparing, and thiazide diuretics.

Therefore, when spironolactone oral suspension and NSAIDs are used concomitantly, monitor closely to determine if the desired effect of the diuretic is obtained [see Clinical Pharmacology ( 12.3 )] .
