When is it appropriate to use a short acting beta agonist
Short Acting Beta Agonists (SABA)
so short-acting beta agonist
bronchodilator mule ating the the beta
receptors on the bronchioles smooth
muscle and they have a very quick onset
and because of that they're considered
the first-line treatment for patients
with asthma symptoms and there's about
five short-acting beta agonists you may
expect to see on the exam albuterol is
really the drug of choice for patients
who are wheezing it's the fastest and
the most effective beta-2 agonist Laval
butyl has less cardiac side effects than
albuterol so if you have a patient whose
heart rate has increased more than 20
beats per minute may be a good choice
and the other three per bureau meta
precht eronel and racemic epinephrine
those are just here for completions sake
you probably want to see them on the
exam but you may so the key points I
want you to remember regarding
short-acting beta agonists are that
number one you should prescribed these
first any time a patient on the exam is
showing acute asthma symptoms or there's
evidence that they're having an asthma
attack secondly if the patient's heart
rate increases while taking any of these
beta agonists then you should change to
a different drug within the same class
such as level butor all which is known
to have less cardiac side effects or you
can decrease the dosage so long as it
still remains therapeutic so don't go
too low with the dosage the third thing
to keep in mind is to not combine
short-acting beta agonists
together so you don't want to combine
albuterol with Laval butyl or medicate
eronel with racemic epinephrine that's
never a good idea and that will lose you
points on the exam for sure and finally
on the exam you can mix short-acting
beta agonists with anticholinergics such
as if trevean bromide
