Angiotensin II Receptor Blockers (ARBs)
These agents act further down the angiotensin pathway than
the ACE inhibitors and block the effects of angiotensin II on the cells
of the blood vessel wall. These agents are used in hypertension. Studies
are underway on their use in heart attack patients and patients with congestive
ARBs tend to have fewer side effects than ACE inhibitors in terms
of cough. They are equally effective in terms of blood pressure control.
