Losartan/Hydrochlorothiazide fixed combination versus amlodipine monotherapy in korean patients with mild to moderate hypertension.

Background And Objectives: The antihypertensive efficacy and tolerability of losartan (LST) in fixed combination with hydrochlorothiazide (HCTZ) has not been compared to those of amlodipine monotherapy in Asians. This is an important comparison to draw, because Asians have been suggested to respond more favorably to calcium channel blockers and less favorably to angiotensin-converting enzyme inhibitors in comparison to Westerners. We sought to compare these two regimens in Korean patients with mild to moderate hypertension.
