Interação entre Amilorida e Bisoprolol + hidroclorotiazida

Hyperkalemia occurs commonly (about 10%) when amiloride is used without a kaliuretic diuretic.

When amiloride HCl is used concomitantly with a thiazide diuretic in patients without these complications, the risk of hyperkalemia is reduced to about 1-2 percent.

It is thus essential to monitor serum potassium levels carefully in any patient receiving amiloride, particularly when it is first introduced, at the time of diuretic dosage adjustments, and during any illness that could affect renal function.

Diabetes Mellitus In diabetic patients, hyperkalemia has been reported with the use of all potassium-conserving diuretics, including amiloride HCl, even in patients without evidence of diabetic nephropathy.

(See WARNINGS .) Lithium generally should not be given with diuretics because they reduce its renal clearance and add a high risk of lithium toxicity.

Because of the relative beta 1 -selectivity of bisoprolol fumarate, bisoprolol fumarate and hydrochlorothiazide tablets may be used with caution in patients with bronchospastic disease who do not respond to, or who cannot tolerate other antihypertensive treatment.

Drug Interactions Bisoprolol fumarate and hydrochlorothiazide tablets may potentiate the action of other antihypertensive agents used concomitantly.

Other antihypertensive drugs - additive effect or potentiation.

Diuretic agents reduce the renal clearance of lithium and add a high risk of lithium toxicity.

Nonsteroidal anti-inflammatory drugs - In some patients, the administration of a nonsteroidal anti-inflammatory agent can reduce the diuretic, natriuretic, and antihypertensive effects of loop, potassium sparing, and thiazide diuretics.
