Aceon (Perindopril Erbumine) - Drug Interactions, Contraindications, Overdosage, etc

 
 



DRUG INTERACTIONS

Drug Interactions:

Diuretics: Patients on diuretics, and especially those started recently, may occasionally experience an excessive reduction of blood pressure after initiation of ACEON® Tablets therapy. The possibility of hypotensive effects can be minimized by either discontinuing the diuretic or increasing the salt intake prior to initiation of treatment with perindopril. If diuretics cannot be interrupted, close medical supervision should be provided with the first dose of ACEON® Tablets, for at least two hours and until blood pressure has stabilized for another hour. (See WARNINGS and DOSAGE AND ADMINISTRATION)

The rate and extent of perindopril absorption and elimination are not affected by concomitant diuretics. The bioavailability of perindoprilat was reduced by diuretics, however, and this was associated with a decrease in plasma ACE inhibition.

OVERDOSAGE

In animals, doses of perindopril up to 2,500 mg/kg in mice, 3,000 mg/kg in rats and 1,600 mg/kg in dogs were non-lethal. Past experiences were scant but suggested that overdosage with other ACE inhibitors was also fairly well tolerated by humans. The most likely manifestation is hypotension, and treatment should be symptomatic and supportive. Therapy with the ACE inhibitor should be discontinued, and the patient should be observed. Dehydration, electrolyte imbalance and hypotension should be treated by established procedures.

However, of the reported cases of perindopril overdosage, one (dosage unknown) required assisted ventilation and the other developed hypothermia, circulatory arrest and died following ingestion of up to 180 mg of perindopril. The intervention for perindopril overdose may require vigorous support (see below).

Laboratory determinations of serum levels of perindopril and its metabolites are not widely available, and such determinations have, in any event, no established role in the management of perindopril overdose.

No data are available to suggest physiological maneuvers (e.g., maneuvers to change the pH of the urine) that might accelerate elimination of perindopril and its metabolites. Perindopril can be removed by hemodialysis, with clearance of 52 mL/min for perindopril and 67 mL/min for perindoprilat.

Angiotensin II could presumably serve as a specific antagonist-antidote in the settling of perindopril overdose, but angiotensin II is essentially unavailable outside of scattered research facilities. Because the hypotensive effect of perindopril is achieved through vasodilation and effective hypovolemia, it is reasonable to treat perindopril overdose by infusion of normal saline solution.

CONTRAINDICATIONS

ACEON® (perindopril erbumine) Tablets is contraindicated in patients known to be hypersensitive to this product or to any other ACE inhibitor. ACEON® Tablets is also contraindicated in patients with a history of angioedema related to previous treatment with an ACE inhibitor.
