There are many reasons why gaining control over high blood pressure (BP) in older patients is desirable. When choosing an antihypertensive agent for older patients, physicians should seek a drug that sustains BP control, especially in the last six hours of the dosing interval or if a dose is missed. Agents with a long duration of action that inhibit the renin-angiotensin system (RAS) are likely to be more useful in controlling the early-morning surges in norepinephrine that have been linked to target organ damage and stroke, particularly in older patients.
Key words: hypertension, renin-angiotensin, angiotensin-receptor blockers, norepinephrine, peroxisome proliferator-activated receptor (PPAR).
