Other information


Indication
For the treatment of hypertension.

Pharmacology
Irbesartan, an angiotensin II receptor antagonist similar to losartan and valsartan, is used alone or with hydrochlorothiazide to treat hypertension

Mechanism Of Action
Irbesartan antagonizes angiotensin II, the primary vasoactive hormone of the renin-angiotensin system, at the AT1 receptor subtype. As angiotensin II is vasoconstrictor which stimulates aldosterone secretion by the adrenal gland, blockage of its effects results in a decrease in systemic vascular resistance.

Drug Category
Antihypertensive Agents; Angiotensin II Receptor Antagonists; ATC:C09CA04

Brand Names/Synonyms
Avalide; Avapro; CHEMBANK1635; Irbesarran; Irbesartan; Irbesartan [Usan:Inn]; Lrbesartan

Dosage Forms
Oral tablets

Absorption
60-80%

Interactions
-->Interactions for Irbesartan:

No significant drug-drug pharmacokinetic (or pharmacodynamic) interactions have been found in interaction studies with hydrochlorothiazide, digoxin, warfarin, and nifedipine.

In vitro studies show significant inhibition of the formation of oxidized irbesartan metabolites with the known cytochrome CYP 2C9 substrates/inhibitors sulphenazole, tolbutamide and nifedipine. However, in clinical studies the consequences of concomitant irbesartan on the pharmacodynamics of warfarin were negligible. Based on in vitro data, no interaction would be expected with drugs whose metabolism is dependent upon cytochrome P450 isozymes 1A1, 1A2,2A6,2B6,2D6,2E1,or 3A4.

In separate studies of patients receiving maintenance doses of warfarin, hydrochlorothiazide, or digoxin, irbesartan administration for 7 days had no effect on the pharmacodynamics of warfarin (prothrombin time) or pharmacokinetics of digoxin. The pharmacokinetics of irbesartan were not affected by coadministration of nifedipine or hydrochlorothiazide.
