Mechanism of Action
Hydrochlorothiazide increases renal excretion of sodium and chloride and reduces cardiac load. Losartan is an angiotensin II receptor (type AT1) antagonist antihypertensive which acts by blocking the actions of angiotensin II of renin-angiotensin-aldosterone system. The drug and its active metabolite selectively block the vasoconstrictor and aldosterone secreting effects of angiotensin II. The two drugs exert additive effects in hypertension.
