| '''Irbesartan''' (INN) ({{pronEng|ɜrbəˈsɑrtən}}) is an [[angiotensin II receptor antagonist]] used mainly for the treatment of [[hypertension]]. Irbesartan was developed by Sanofi Research (now part of [[sanofi-aventis]]). It is jointly marketed by [[sanofi-aventis]] and [[Bristol-Myers Squibb]] under the trade names '''Aprovel''', '''Karvea''', and '''Avapro'''.

| ===Indications===
| |
| As with all angiotensin II receptor antagonists, irbesartan is indicated for the treatment of [[hypertension]]. Irbesartan may also delay progression of diabetic nephropathy and is also indicated for the reduction of renal disease progression in patients with type 2 diabetes,<ref name="Lewis-2001">{{cite journal | author=Lewis EJ, Hunsicker LG, Clarke WR, Berl T, Pohl MA, Lewis JB, Ritz E, Atkins RC, Rohde R, Raz I; Collaborative Study Group. | title=Renoprotective effect of the angiotensin-receptor antagonist irbesartan in patients with nephropathy due to type 2 diabetes. | journal=N Engl J Med | year=2001 | volume=345 | issue=12 | pages=851-60 | id=PMID 11565517}}</ref> hypertension and microalbuminuria (>30 mg/24 hours) or proteinuria (>900 mg/24 hours).<ref name="Rossi2006">Rossi S, editor.

| ===Combination with diuretic===
| |
| Irbesartan is also available in a combination formulation with a low dose [[thiazide diuretic]], invariably [[hydrochlorothiazide]], to achieve an additive antihypertensive effect. Irbesartan/hydrochlorothiazide combination preparations are marketed under similar trade names to irbesartan preparations, including '''CoAprovel''', '''Karvezide''', '''Avalide''' and '''Avapro HCT'''.
