Hi, welcome to our video on medications
This video, we're going to focus on
a particular group of medications
known as calcium channel blockers.
Now, you'll see this chart of blood pressure
categories in most of our videos.
So keep in mind that normal is
< 120 systolically,
and < 80 diastolically.
Now, you watch the numbers rise,
but anything higher than 120/80
means you're starting to get
into some elevation.
Goes all the way up through what
we see as a hypertensive crisis.
That's a systolic number that's > 180
and a diastolic number that's > 120.
Now I want to underscore
hypertensive crisis means you
don't treat this at home.
A patient with a blood pressure this
high is in significant danger
and needs to seek advanced medical help.
Now, just a quick review, again,
of the medications
we use to treat hypertension.
We have ACE inhibitors, and
one of our tips is
the generic names for ACE
inhibitors ends in "pril."
We have angiotensin II receptor blockers
and they end in "tan."
We talk about those in a separate video.
We've got beta blockers
and they end in "olol,"
and we've got calcium channel blockers
and they usually end in "pine."
So those are the ones that we're
going to zero in on for this video.
But we've got a couple others
that are kind of in our
bag of tricks in how we teach hypertension.
Sympatholytic drugs, other
than beta blockers,
those are drugs that kind of go against
the effect of the sympathetic
Because, remember, the sympathetic
nervous system causes everything to --
heart beats faster, stronger,
because we're in danger.
Sympatholytic drugs are the
exact opposite of that.
We can use direct vasodilators
because when you vasodilate the vessels,
the blood pressure will lower,
and we can use selective aldosterone-
because those will help us have less volume
on board and should therefore, give us
a lower blood pressure.
