Why can we give kids more Albuterol than adults?


because they metabolize the drug faster than the drug can reach its potential


What percent of Albuterol MDI actually goes to the lungs? rest goes where?


30% goes to lungs
70% to stomach


1 ML =


1 cc


1 mg=


.001 grams


500 ml=


.5L


We use mg's for?


solutions


Mcgs are used for?


inhalers


Parasympathetic controls what?


SLUD
salivation, lacrimation,urination, defication
when you stimulate, you get more
Uses ACH to create SLUD


Sympathetic controls what?


Fight or Flight
not essential to life
Uses two major receptors:
Alpha and Beta 1& 2


Parasympathomimetic does what?


stimulates parasympathetic nervous system


Parasympatholytic does what?


blocks effects of parasympathetic nervous system
Increases HR and causes bronchodilation


Sympathomimetic does what?


stimulates sympathetic nervous system


Sympatholytic does what?


blocks effects of sympathetic nervous system


Cholinergic does what?


stimulates a receptor for ACH
same as parasympathomimetic


When stimulated; the sympathetic nervous system throw these Alpha and Beta 1 and 2 into action. What do these receptors do in turn?


Alpha- stimulates vasoconstriction
Beta 1- Increases HR(think 1 heart=
beta 1)
Beta 2- causes bronchodilation
(think 2 lungs=beta 2)



Adrenergic does what?
Give an example of and adrenergic drug


stimulates a receptor for Norepinephrine and Epinephrine causing bronchodilation
Albuterol


Anticholinergic does what?


blocks ACH in turn blocking parasympathetic system



Antiadrenergic does what?


blocks Norepinephrine and Epinephrine
is a sympatholytic


Anticholinergic is parasympatholytic blocking SLUD so if we are blocking a natural derease in HR caused by SLUD then an anticholinergic would?


increase HR


Adrenergic is hand in hand with?


Sympathomimetic


Adrenergics are also referred to as?


B-agonists
meaning they stimulate B2(bronchoconstriction)


What are indications for adrenergic bronchodilators?


Relaxation of airway bronchial smooth muscle in the presence of reversible airflow obstruction


What are some short acting adrenergic bronchodilators?
Rescue inhalers?


Albuterol, levalbuterol, and pirbuterol


Long acting adrenergic brochodilators?


Salmeterol and Formoterol


Another unspecific adrenergic bronchodilator?


Racemic Epinephrine


Albuterol

0.5ml (2.5mg) via SVN



Albuterol Dose
MDI


2 puffs of 90mcg


Albuterol Dose
DPI

Onset of bronchodilation for Albuterol?


15 min.


Time to peak bronchodilating effect for Albuterol?


30-60 min.


Duration of action Albuterol


5-8 hours


Levalbuterol is also known as:


Xopenex


Adult dosages of Levalbuterol


0.63mg & 1.25mg


Levalbuterol MDI dose


2 puffs of 90 mcg/puff Q4-6


What 2 drugs are in Advair?


salmeterol and flovent
