DrugBank Description: | Losartan is an angiotensin II receptor blocker (ARB) used to treat hypertension. Angiotensin-converting enzyme (ACE) inhibitors are used for a similar indication but are associated with a cough. When patients with ACE inhibitor associated coughs are switched to ARBs like losartan, they have an incidence of cough similar to placebo or . Losartan is available as losartan potassium oral tablets as well as a combination tablet of losartan potassium and hydrochlorothiazide. Patients taking losartan should have their renal function and potassium levels monitored. Losartan was granted FDA approval on 14 April 1995. |

DrugBank Targets: | Type-1 angiotensin II receptor antagonist |
DrugBank MoA: | Losartan reversibly and competitively prevents angiotensin II binding to the AT<sub>1</sub> receptor in tissues like vascular smooth muscle and the adrenal gland. Losartan and its active metabolite bind the AT<sub>1</sub> receptor with 1000 times more affinity than they bind to the AT<sub>2</sub> receptor. The active metabolite of losartan is 10-40 times more potent by weight than unmetabolized losartan as an inhibitor of AT<sub>1</sub> and is a non-competitive inhibitor. Losartan's prevention of angiotensin II binding causes vascular smooth muscle relaxation, lowering blood pressure. Angiotensin II would otherwise bind to the AT<sub>1</sub> receptor and induce vasoconstriction, raising blood pressure. |
DrugBank Pharmacology: | Losartan is an angiotensin II receptor blocker used to treat hypertension, diabetic nephropathy, and to reduce the risk of stroke. Losartan has a long duration of action as it is given once daily. Patients taking losartan should be regularly monitored for hypotension, renal function, and potassium levels. |
DrugBank Indication: | Losartan is indicated to treat hypertension in patients older than 6 years, reduce the risk of stroke in patients with hypertension and left ventricular hypertrophy (though this benefit may not extend to patients with African heritage), and to treat diabetic nephropathy with elevated serum creatinine and proteinuria in patients with type 2 diabetes and hypertension. Losartan with hydrochlorothiazide is indicated to treat hypertension and to reduce the risk of stroke in patients with hypertension and left ventricular hypertrophy (though this benefit may not extend to patients with African heritage). |
