Investigational Drug Details

Drug ID: D309
Drug Name: Irbesartan
Synonyms:
Type: small molecule
DrugBank ID: DB01029
DrugBank Description: Irbesartan is an angiotensin receptor blocker (ARB) indicated to treat hypertension or diabetic nephropathy.[L7456,L7459] It can also be used as part of a combination product with [hydrochlorothiazide] for patients not well controlled or not expected to be well controlled on monotherapy.[L7459] Unlike angiotensin converting enzyme inhibitors, ARBs are not associated with a dry cough.[L7456,L7459] Irbesartan was granted FDA approval on 30 September 1997.[L7456,L7459]
PubChem ID: 3749
CasNo: 138402-11-6
Repositioning for NAFLD: Yes
SMILES: CCCCC1=NC2(CCCC2)C(=O)N1CC1=CC=C(C=C1)C1=CC=CC=C1C1=NNN=N1
Structure:
InChiKey: YOSHYTLCDANDAN-UHFFFAOYSA-N
Molecular Weight: 428.5294
DrugBank Targets: Type-1 angiotensin II receptor; Transcription factor AP-1
DrugBank MoA: Irbesartan prevents angiotensin II binding to the AT<sub>1</sub> receptor in tissues like vascular smooth muscle and the adrenal gland.[L7456,L7459] Irbesartan and its active metabolite bind the AT<sub>1</sub> receptor with 8500 times more affinity than they bind to the AT<sub>2</sub> receptor.[L7456,L7459] Irbesartan's prevention of angiotensin II binding causes vascular smooth muscle relaxation and prevents the secretion of aldosterone, lowering blood pressure.[L7456,L7459] Angiotensin II would otherwise bind to the AT<sub>1</sub> receptor, inducing vasoconstriction and aldosterone secretion, raising blood pressure.[L7456,L7459]
DrugBank Pharmacology: Irbesartan is an angiotensin receptor blocker used to treat hypertension and diabetic nephropathy.[L7456,L7459] It has a long duration of action as it is usually taken once daily and a wide therapeutic index as doses may be as low as 150mg daily but doses of 900mg/day were well tolerated in healthy human subjects.[L7456,L7459,A181165]
DrugBank Indication: Irbesartan is indicated to treat hypertension and diabetic nephropathy in hypertensive patients with type 2 diabetes, elevated serum creatinine, and proteinuria.[L7456] A combination product with hydrochlorothiazide is indicated for hypertension in patients with uncontrolled hypertension with monotherapy or first line in patients not expected to be well controlled with monotherapy.[L7459]
