This document discusses angiotensin II receptor blockers (ARBs), which are used to treat hypertension and other conditions. It lists the major ARBs available worldwide and in Bangladesh specifically. Data on the top selling ARBs in Bangladesh from 2001-2012 shows losartan as the highest selling, with strong growth from olmesartan and irbesartan as well. Clinical trials findings suggest azilsartan may provide better blood pressure control than other ARBs. A price comparison table shows the monthly and annual costs of common ARBs.
