Current Treatments For Hypertension
Numerous recent, large, randomized clinical trials have indicated
that treating hypertension in older adults can reduce the risk of kidney
disease, stroke,
and cardiovascular events.10 Unfortunately, bringing blood pressure down to healthy levels is easier said than done. Many clinicians start therapy with a mild diuretic (“water pill”) at
low doses, then gradually increase doses until either blood pressure is
controlled or
the maximum dose is reached.10
However, nearly 75% of patients do not get adequate blood pressure control on a single drug, which means a second medication is often
necessary.11 This process may continue until a person finds himself or herself on three, four, or more drugs.2,11,12
A frequently prescribed class of antihypertensives used today are the angiotensin II receptor blockers.
These drugs block the angiotensin
II receptor and often induce more profound and sustained blood
pressure control than older classes of medications. However, there are
side effect risks
associated with angiotensin II receptor blocker drugs. In some
individuals, angiotensin II receptor blockers can cause an increase in
potassium and changes
in kidney function. Also, do not take angiotensin receptor blockers
if you are pregnant or plan on becoming pregnant because this class of
medication can
cause harm to the fetus.
One of the most commonly used approaches to treating hypertension
involves the combination of two drugs: an ACE inhibitor and a calcium
channel blocker.2,3 A large 2013 study demonstrated that for
most people, this combination was more effective at reducing
cardiovascular consequences of
hypertension than using either drug with a diuretic.13 This combination also demonstrated the greatest probability of reducing death.14
Here’s how the combination drug therapy works.
Angiotensin converting enzyme, or ACE, is a natural enzyme in the body that activates the hormone angiotensin, which causes blood vessels to
constrict, thus increasing blood pressure.15 Inhibiting ACE can return blood pressure to lower levels. ACE inhibitors alone, however, are not
always entirely effective, which is why doctors often combine them with a second drug called a calcium channel blocker.16
Calcium channel blockers lower blood pressure by a different
mechanism than ACE inhibitors. They prevent the entry of calcium ions
into muscle cells in the
arterial wall. Since calcium ions are a major signal telling those
cells to contract and raise muscle tone in the artery, blocking calcium
influx into the
cells will prevent contraction and lower blood pressure.17
Use of the combination of an ACE inhibitor and a calcium channel
blocker has become one of the mainstays of modern pharmacological blood
pressure control,
since the two drugs act in parallel, but different ways.
Unfortunately, as is usually the case, both drugs bring with them side
effects.17,18
Scientists have discovered two natural ingredients that work in ways
similar to mainstream drugs, but without the numerous side effects.
Olive leaf extract
and celery seed extract act as ACE inhibitors and calcium channel
blockers, respectively.6,7 Each has been shown in clinical studies to lower
blood pressure.
