For the treatment of hypertension.

Losartan is the first of a class of antihypertensive agents called angiotensin II (AG II) receptor antagonists. It is, along with its longer acting active metabolite (E-3174), a specific and selective AT1 receptor antagonist. Losartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II by selectively blocking the binding of angiotensin II to the AT1 receptor found in many tissues, (e.g., vascular smooth muscle, adrenal gland).

Well absorbed, the systemic bioavailability of losartan is approximately 33%

Hypotension and tachycardia; Bradycardia could occur from parasympathetic (vagal) stimulation, LD₅₀= 1000 mg/kg (orally in rat)
