Interaksi Amlodipin dan benazepril dan Fosinopril dan hidroklorotiazid

Fosinopril sodium and hydrochlorothiazide is also contraindicated in patients who are hypersensitive to fosinopril, to any other ACE inhibitor, to hydrochlorothiazide, or other sulfonamide-derived drugs, or any other ingredient or component in the formulation.

Like other ACE inhibitors, fosinopril has been only rarely associated with hypotension in uncomplicated hypertensive patients.

The thiazide component of fosinopril sodium and hydrochlorothiazide may potentiate the action of other antihypertensive drugs, especially ganglionic or peripheral adrenergic-blocking drugs.

Other ACE inhibitors have had less than additive effects with beta-adrenergic blockers , presumably because drugs of both classes lower blood pressure by inhibiting parts of the renin-angiotensin system.

Fosinopril sodium and hydrochlorothiazide tablets should be used cautiously in patients receiving concomitant therapy with other antihypertensives.

Symptomatic hypotension is most likely to occur in patients who have heart failure, severe aortic or mitral stenosis, obstructive hypertrophic cardiomyopathy or have been volume or salt depleted as a result of diuretic therapy, dietary salt restriction, dialysis, diarrhea, or vomiting.

In patients with congestive heart failure, start amlodipine and benazepril hydrochloride therapy under close medical supervision; follow closely for the first 2 weeks of treatment and whenever the dose of the benazepril component is increased or a diuretic is added or its dose increased.

Risk factors for the development of hyperkalemia include renal insufficiency, diabetes mellitus, and the concomitant use of potassium-sparing diuretics, potassium supplements, and/or potassium-containing salt substitutes.

Potassium supplements/potassium-sparing diuretics: hyperkalemia ( 7.1 )

Potassium-sparing diuretics (spironolactone, amiloride, triamterene, and others) or potassium supplements can increase the risk of hyperkalemia.
