DescriptionLosartan is an angiotensin II receptor blocker (ARB) used to treat hypertension.[L7423] Angiotensin-converting enzyme (ACE) inhibitors are used for a similar indication but are associated with a cough.[L7423] When patients with ACE inhibitor associated coughs are switched to ARBs like losartan, they have an incidence of cough similar to placebo or [hydrochlorothiazide].[L7423] Losartan is available as losartan potassium oral tablets as well as a combination tablet of losartan potassium and hydrochlorothiazide.[L7423,L7426] Patients taking losartan should have their renal function and potassium levels monitored.[L7423] Losartan was granted FDA approval on 14 April 1995.[L7423]
