Drug-Induced Pulm Disease Flashcards
most common drug-induced resp problem
bronchospasm
four methods of bronchospasm
Anaphylaxis (IgE)
COX inhibition
Pharmacologic effects
Direct airway irritation (smoke, n-acetylcysteine)
Samter’s syndrome
Asthma
nasal polyps
aspirin intolerance
aspirin/NSAIDs can cause
bronchospasm
what class is used to treat NSAID induced bronchospasm (DOC)
Leukotriene antagonists (Zileutron)
therapy options for aspirin/NSAID bronchospasm
COX2 selective NSAIDs
Acetaminophen
Cross sensitivity in NSAID induce BS
Ibuprofen/naproxen
yellow dye tartrazine
(colors food, drinks, cosmetics)
the use of this drug early in life may increase risk of asthma and allergic disease
Acetaminophen
beta blockers can cause
bronchospasm (by directly inhibiting B2 receptors)
what could you use to treat b blocker induced bronchospasm
anticholinergics (ipratropium)
management options for people with b blocker bronchospasm
inhaled bronchodilator
use selective b blockers, lowest dose possible
potassium metabisulfite, a preservative in food and wine and some injectable drugs, can induce what
bronchospasm
mechanisms of sulfite induced BS
- sulfite converted to sulfur dioxide (parasymp)
- IgE mediated
- Reduced enzyme sulfite oxidase (which catalyzes sulfITES to sulfATES)
pretreatment for sulfite induced BS
cromolyn, anticholinergics, cyanocobalamin
inhaled agents can cause
bronchospasm
