COPD drugs Flashcards
Mast cell stabilizer
cromolyn sodium
cromyolyn sodium MOA
- stabilize mast cells –> prevent histamine release
- decrease bronchial hyper-reactivity (not direct bronchodilator)
What is the only anti-asthmatic that blocks both early and late phase responses?
cromolyn sodium
Cromolyn uses
- decrease hyper responsiveness
- mild to moderate asthma with allergic component
- limited overall use
- NOT bronchodilating
- NOT for acute asthma
Cromolyn adverse effects
- cause bronchospasm, wheezing
- throat irritation, cough, dry mouth
- bad taste
- joint swell, pain, HA
What is one of the safest anti-asthma meds?
cromolyn
Leukotriene modifiers
montelukast
zileuton
LTD4 leukotriene receptor antagonist
montelukast
leukotriene synthesis inhibitor
zileuton
Alternative to steroids for mild persistent asthma
leukotriene modifiers
leukotriene modifiers use
- aspirin sensitive asthma
- allergic rhinitis, chronic sinus
- limited effects in acute attacks
- may cause some bronchodilation
Leukotriene modifiers side effects
- well tolerated
- mild HA, GI
zileuton side effects
occasional reversible liver toxicity increase serum (warfarin and theophylline)
montelukast side effects
psychosis/depression risk
Biologic for airway
omalizumab
omalizumab MOA
prevent IgE from binding
- blocks all components of allergic response
omalizumab PK
onset 12 weeks
omalizumab use
- moderate to severe disease not well controlled by inhaled steroids
- allergic asthma –> non seasonal allergic
- reduce frequency and severity of exacerbation
- allow reduction of anti-inflammatory GC dose
omalizumab adverse effects
- irritation at injection site
- CV and stroke risk
BBW omalizumab
analphylaxis
new subset of asthma
eosinophilic asthma
