Interaction entre Chlorothiazide et Moexipril

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

Volume- and salt-depletion should be corrected and, in general, diuretics stopped, before initiating therapy with moexipril hydrochloride (see PRECAUTIONS, Drug Interactions , and ADVERSE REACTIONS ).

In these patients, moexipril hydrochloride therapy should be started under close medical supervision, and patients should be followed closely for the first two weeks of treatment and whenever the dose of moexipril or an accompanying diuretic is increased.

Drug Interactions Diuretics: Excessive reductions in blood pressure may occur in patients on diuretic therapy when ACE inhibitors are started.

Potassium Supplements and Potassium-Sparing Diuretics: Moexipril hydrochloride can increase serum potassium because it decreases aldosterone secretion.

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.
