Pulmonary Pharm Flashcards
What are the 3 subclasses of bronchodilators
Beta 2 Agonists
Anticholinergics
Xanthine derivatives
3 subclasses of anti-inflammatories
leukortriene receptor antagonist (LTRAs)
inhlaed glucocoritcoids
mast cell stabilizers
2 Other medication classes
omalizumab
roflumilast
Classes for COPD treatment that dilate bronchioles
beta 2-adrenergics
inhaled anticholinergics
xanthine derivatives
Classes for COPD treatment that decrease bronchial inflammation
glucocorticoids
mast cell stabilizer
LTRAs
MOA of bronchodilators
work by relaxing bronchial smooth muscle
Causes dilation of bronchi/bronchioles
3 classes of bronchodilators
Beta-Adrenergic Agonists
Anti-cholinergics
Xanthine derivatives
2 beta-adrenergic agonists Short Acting drugs
Albuterol (Proventil) PO/Inhalant
Levalbuterol (Xopenex) Inhalant
2 beta-Adrenergic Agonist Long Acting drugs
Salmetrol (Servent)
Formoterol (Foradil)
What type of beta-adrenergic agonist should be used in an asthmatic attack
Short Acting
What is the timing of short acting beta agonists
inhaled q 4-6 hrs
what is the timing of long acting beta agonists
inhaled q 12 hours
What type of beta agonists are resuce drugs
short acting
what are long acting beta agonists used for
prevention
what is the duration of long acting beta agonists
12-24 hrs
MOA of beta-adrenergic agonist
mic action of SNS flight or flight
Relax and dilate the airways by stimulating the beta2-adrenergic receptors throughout the lungs
Bronchial dilation & increased airflow into and out of the lungs=goal
what are the 3 subtypes of beta-adrenergic agonist
Non-selective adrenergic drugs– stimulate both beta-1 AND beta-2 receptors AND alpha receptors (epinephrine)
Non-selective beta-adrenergic– stimulate both beta-1 AND beta-2 receptors (metaproterenol)
Selective beta-2 receptors (albuterol) preferred medication to treat pulmonary conditions
MOA of non-selective drugs
stimulate alpha receptors= vasoconstriction
Decreases edema/swelling in mucous membranes, limits amount of secretions
stimulate beta1= cardiovascular effects
What effects would these be?
CNS stimulation also occurs nervousness/tremors occur
Indications for beta adrenergic agonists
prevention or relief of bronchospasm related to asthma/bronchitis/other pulmonary conditions
Will see them used for conditions outside the pulmonary system
Contraindications for beta adrenergic agonist
uncontrolled hypertension, cardiac dysrhythmias, high risk for stroke
beta-adrenergic agonist should not be given with what other drugs
MAOIs and sympathomimetics (ephedrine/sudafed) bc risk of hypertension
What may diabetics need with beta-adrenergic agonist
Diabetics may need higher doses of meds because raises blood sugar
