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
