are in this video we are going to get
into respiratory medications and
specifically we're going to talk about
respiratory medications that cause
bronchodilation so the first class I'm
going to discuss here are beta to add
your genic agonists so if you're
following along with cards I'm on card
number one and the two medications that
I'd be familiar with that fall under
this class are albuterol and some metal
so these medications can be used for
asthma or COPD they can be used alone or
in combination with a glucocorticoid or
with an anticholinergic medication such
as a proto pium the motive action of
beta to a genetic agonist is to bind to
the beta 2 receptors in the lungs so the
way to remember that beta 2 receptors
are in the lungs is that you have two
lungs as opposed to beta 1 receptors
which are on the heart and you only have
one heart so these medications bind to
those beta 2 receptors and they result
in bronchodilation they help open up the
airways these medications do carry some
common side effects including like
nervousness tremors possible chest pain
and possible palpitations there is some
there's a key difference between
albuterol and some metals so albuterol
is a short-acting beta-2 a genetic
agonist so it is used for acute asthma
attacks
so albuterol starts with the letter A
and acute asthma attacks also I'll start
with the letter A so that will help you
remember that cell metal is long acting
and it is more for prevention of asthma
attacks so I think about eating salmon
you know say man supposed to be very
healthy and it will help you lead a long
life if you incorporate salmon into your
diet so I think about salmon and leading
a long life and that helps me to
remember that Psalm edirol is long
acting in terms of if you're using a
beta 2
a Trojan antagonist with a
glucocorticoid you want to use the
bronchodilator first so use the beta to
a genetic agonist first wait five
minutes and then use the glucocorticoid
that's going to be very important to
know and the way you can remember it is
that B comes before G so bronchodilator
first wait five minutes and then the
glucocorticoid all right so moving on to
cart - we're going to talk about
xanthines the key medication that falls
within this class is theophylline so
theophylline can be used for long-term
control of asthma or COPD it works by
increasing C AB which ultimately results
in bronchodilation so it comes with some
very serious side effects however so in
addition to GI upset headache and
nervousness it also carries risk for
dysrhythmias as well as seizures and
because of those very serious side
effects this medication is not used as
much as other medications for asthma and
COPD if your patient is going to be on
theophylline they will need to get
regular blood draws to really monitor
the levels of theophylline in their
bloodstream so the therapeutic levels
should be somewhere between 10 and 20
micrograms per milliliter so the way I
remember this medication is the you know
the drug name is theophylline so the
beginning of that is the Theo
so Theo means God or God like so if you
take theophylline you might end up
seeing God sooner versus later because
of those very serious side effects
all right now we're going to talk about
anticholinergic medications that are
either inhaled or intranasal so the key
medication that I would know that's an
anticholinergic in this class is it bruh
chögyam so in Petro priam can be used
for COPD it can be used for rhinitis
which is a
for congestion like a runny nose it can
also be used for asthma but that is
really off-label it can be used alone or
can be used in combination with
albuterol when used in combination with
albuterol that medication is called doin
em so it works by blocking acetylcholine
receptors in the Airways smooth muscle
which causes bronchodilation because
it's an anticholinergic it will have
drying effects so the key side effects
with this medication include dry mouth
as well as a bitter taste and throat or
nasal irritation depending whether we're
using an inhaler or an intranasal form
of epitope IAM so some key teaching that
you'll need to do for your patients you
should advise them to increase their
fluid intake because of the drying
effects they can suck on candy for a dry
mouth and then the petropia m--
albuterol combination which is doing ab
is contraindicated for patients who have
a peanut allergy so that's something to
keep in mind as well okay in my next
video we will be talking about
corticosteroids both inhaled and nasal
we'll be talking about leukotriene
receptor antagonists as well as
antitussive medications so hang in there
with me and we will get through these
medications together
