Wechselwirkung zwischen Chlorothiazid und Perindopril

Symptomatic hypotension is most likely to occur in patients who have been volume or salt-depleted as a result of prolonged diuretic therapy, dietary salt restriction, dialysis, diarrhea or vomiting [see Dosage and Administration (2.1) ] .

Patients should be followed closely for the first two weeks of treatment and whenever the dose of perindopril erbumine and/or diuretic is increased.

Some perindopril erbumine-treated patients have developed minor and transient increases in blood urea nitrogen and serum creatinine especially in those concomitantly treated with a diuretic.

Risk factors for the development of hyperkalemia include renal insufficiency, diabetes mellitus and the concomitant use of agents such as potassium-sparing diuretics, potassium supplements and/or potassium-containing salt substitutes [see Drug Interactions (7.2) ] .

Potassium-Sparing Diuretics/Potassium Supplements: Hyperkalemia.

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

Other Antihypertensive Drugs - additive effect or potentiation.

…renal function (e.g., elderly patients or patients who are volume-depleted, including those on diuretic therapy) who are being treated with NSAIDs, including selective COX-2 inhibitors, the co-administration of angiotensin II receptor antagonists or ACE inhibitors may result in a further deterioration of renal function, including possible acute renal failure.

These interactions should be considered in patients taking NSAIDs including selective COX-2 inhibitors concomitantly with diuretics and angiotensin II antagonists or ACE inhibitors.
