Interação entre Amilorida e Tolvaptana

Co-administration of diuretics also increases the risk of too rapid correction of serum sodium and such patients should undergo close monitoring of serum sodium.

Monitor serum potassium during concomitant therapy with ( 7.2 ): Angiotensin receptor blockers Angiotensin converting enzyme inhibitors Potassium sparing diuretics 7.1 CYP3A Inhibitors and Inducers Strong CYP3A Inhibitors Tolvaptan's AUC was 5.4 times as large and C max was 3.5 times as large after co-administration of tolvaptan and 200 mg ketoconazole [see Warnings…

Adverse reactions of hyperkalemia were approximately 1 to 2% higher when tolvaptan was administered with angiotensin receptor blockers, angiotensin converting enzyme inhibitors and potassium sparing diuretics compared to administration of these medications with placebo.

Dehydration and hypovolemia can occur, especially in potentially volume-depleted patients receiving diuretics or those who are fluid restricted.

Angiotensin Receptor Blockers, Angiotensin Converting Enzyme Inhibitors and Potassium Sparing Diuretics Although specific interaction studies were not performed, in clinical studies, tolvaptan was used concomitantly with beta-blockers, angiotensin receptor blockers, angiotensin converting enzyme inhibitors and potassium sparing diuretics.
