Respiratory Drugs Flashcards
Xanthines cause bronchodilation by increasing levels of energy producing substance cAMP. Competitively inhibit phosphodiesterase, the enzyme responsible for breaking down cAMP. (higher cAMP contributes to smooth muscle relaxation and inhibits Ig-E induced chemical mediators
Animophylline
Prodrug of theophylline, that is metabolized to theophylline in the body
aminophylline
Sometimes given to patients with status asthmaticus that haven’t responded to fast acting b-agonists such as epinephrine
aminophylline
Adverse effects such as nausea, vomiting, anorexia, GI reflux, transient urination and hyperglycemia, and cardiac AE.
Xanthine derivatives
Consist of plant alkaloids caffeine, theobromine, and theophylline
Xanthine derivatives (natural)
Increase the levels of cAMP
xanthine derivatives
Potential overdose of xanthine derivatives
charcoal
Method for taking respiratory corticosteroid meds
shake, inhale, rinse mouth. Should use aerochamber
Important patient teaching to rinse mouth and gargle with warm water after admin. to prevent development of oral fungal infections.
Fluticasone
If taking a b-agonist bronchodilator, the bronchodilator should be taken several minutes before to provide bronchodilation before admin. of corticosteroid.
Fluticasone patient teaching
Drugs used in treatment of acute asthma attack
Short acting b2-agonists (sympathomimetics)
Inhaled ipratropium treatment for
acute asthma attack
inhaled corticosteroids and LABA (specifically budesone and formoteral - Symbicourt use)
acute asthma attack
Corticosteroid adverse effects
Irritation, dry mouth, oral fungal infections
Can affect any organ (systemic)
The nurse is teaching a group of patients about the use of bronchodilators. It is important to remind them that using bronchodilators too frequently can cause which AE? select all
a) blurred vision
b) increased heart rate
c) decreased heart rate
d) nausea
e) nervousness
