Interação entre Lisinopril + hidroclorotiazida e Quinapril

…sometimes associated with oliguria and/or progressive azotemia, and rarely with acute renal failure and/or death, include patients with the following conditions or characteristics: heart failure, hyponatremia, high dose diuretic therapy, recent intensive diuresis or increase in diuretic dose, renal dialysis, or severe volume and/or salt depletion of any etiology.

No pharmacokinetic interaction was observed when single doses of quinapril hydrochloride and hydrochlorothiazide were administered concomitantly.

It may be advisable to eliminate the diuretic (except in patients with heart failure), reduce the diuretic dose or cautiously increase salt intake (except in patients with heart failure) before initiating therapy with quinapril hydrochloride in patients at risk for excessive hypotension who are able to tolerate such adjustments.

Such patients should be followed closely for the first two weeks of treatment and whenever the dose of quinapril hydrochloride and/or diuretic is increased.

If symptomatic hypotension develops, a dose reduction or discontinuation of quinapril hydrochloride or concomitant diuretic may be necessary.

When a diuretic is added to the therapy of a patient receiving lisinopril, an additional antihypertensive effect is usually observed (see DOSAGE AND ADMINISTRATION ).

Other antihypertensive drugs - additive effect or potentiation.

Leukopenia/Neutropenia/Agranulocytosis: Another angiotensin-converting enzyme inhibitor, captopril, has been shown to cause agranulocytosis and bone marrow depression, rarely in uncomplicated patients but more frequently in patients with renal impairment, especially if they also have a collagen vascular disease.

Most epidemiologic studies examining fetal abnormalities after exposure to antihypertensive use in the first trimester have not distinguished drugs affecting the renin-angiotensin system from other antihypertensive agents.
