Asthma/COPD Flashcards
(27 cards)
Steroids (inhaled, systemic)
Leukotrine modifying agents
Roflumilast
Anti inflammatory agents
Beta 2 agonists
MOA
Act like NE and E at B2 receptors- bind and cause smooth muscle relaxation and mast cell stabalization
-useful in asthma and copd
Beta 2 agonists
AEs
Skeletal muscle tremor Tachycardia Nervousness Hypokalemia MDI: dry mouth, cough
Beta 2 agonists
Available agents
Short acting: fast onset/short duration
-used for acute attack
Long acting: slow onset/long duration
- not used as rescue therapy
- longer half life
- preventative
B2 agonists
Anticholinergic agents
Theophylline
Bronchodilators
Long acting beta agonists
LABAs
Warnings/recommendations
- increase/worsening of increased risk of asthma related deaths for PTs using labas for asthma treatment
- use only when paired with a glucocorticoid
- use for a shortest duration possible
- use in combo product to increase compliance
- desensitize beta 2 receptors; steroids help lessen the desensitizing of the receptors
Albuterol (vetolin, Proventil): PO, MDI, neb
Lavalbuterol (xopenex): MDI, neb
Metaproterenol (alupent, metaprel):PO, neb
Pirbuterol (max air): autohaler

Olodaterol (striverdi respimat): MDI
Vilanterol (breo ellipta, anoro ellipta): powder for inh- only available in combo with fluticasone or umeclidium
Long acting beta 2 agonists
LABAs
Inhaled have beta 2 agonists
Have a low risk of AEs
Systemic beta 2 agonists
Have a a higher risk of AEs
Anticholinergic agents
MOA
Inhibit the Ach effects on bronchial smooth muscle
- use in asthma limited to acute attacks
- technique is very important for use
Aclidinium (Tudorza press air): powder for inh
Ipratopium (atrovent HFA): MDI, neb, nasal spray

Ipratopium + albuterol (combivent):MDI
Ipratopium + fenoterol (duovent)
Tiotoprium (spriva handihaler): oral inhalation
Glycopyrrolate + indacaterol(utibron): powder for inh
Anticholinergic agents (inhaled)
Anticholinergic agent
AEs
Dry mouth Constipation Urinary hesitancy Tachycardia (Anti slud)
Theophylline
MOA
Bronchodilation
Stimulates respiratory center
Augments diaphragm contractility
Theophylline
AE/risks
Not commonly used/last resort
*Narrow therapeutic index: effectiveness and toxicity is very close together (high variability)
Dosing varies by population: smokers(metabolized faster), elderly, children
*monitor closely
Tachycardia, GI upset, nervousness, sleep disturbances
Toxicity: N/V, PVC, seizures, arrhythmia
Corticosteroids
Anti inflammatory agent
MOA
Anti inflammatory
Inhibit. Migration of inflammatory cells
Inhibit mucus production
Improve response to b2 stimulation
Formulations: systemic, inhaled (topical)
Corticosteroids
AEs
Systemic effects
Acute: fluid retention, mood changes, sleep disturbances, increased appetite, hypokalemia, hypoglycemia
Chronic: *growth suppression, cataracts, osteoporosis, HTN, HPA axis suppression
Inhaled: oral candidiasis, dysphonia, brush teeth, rinse mouth
Fluticasone (Flovent): MDI Budensonide (pulmicort): turbohaler, neb Triamcinolone (azmacort): MDI Beclomethasone (beclovent, Qvar): MDI Flunisolide (aero-bid): MDI Ciclesonide (alvesco): MDI
Inhaled corticosteroids
Leukotriene modifying agents
Anti inflammatory
MOA
Reduce inflammation and bronchoconstriction caused by leukotrienes Receptor antagonism (zafirlukast, montelukast) Inhibition of 5-lipoxygenase pathway (Zileuton)
Zafirlukast (accolate)
Montelukast (singulair)
Zileuton (zyflo)
Leukotriene modifiers
Zafirlukast (accolate)
LTD4 antagonist: block LTD4 from binding to its receptor
-important drug inx concerns
AE: GI upset, increased LFTs, suicide risk, anxiety, nightmares, aggression, depression
Montelukast (singulair)
LTD4 antagonist: blocks LYD4 from binding to its receptor
No significant drug inx
AE: GI upset, suicide risk, nightmare, aggression, anxiety, depression
Zileuton (zyflo)
Leukotriene modifier
5-lip oxygenase inhibitor
AE: GI upset, increased LFTs, low WBC, weakness, conjunctivitis, suicide risk, anxiety, nightmares, depression, aggression
liver damage**
Omalizumab (Xolair)
Other anti inflammatory
Biologic agent: monoclonal antibody
-injectable
*Used to treat severe allergic rxn asthma
-binds to free igE to mast cells and basophils and promotes release of inflammatory mediators
Only approved for PTs under 12 with positive skin prick test
