Q

Beta Agonists

A

Short acting:
- Albuterol (inhaled, short-acting, lasts 5 to 15 mins, treats acute bronchospasm)
- Cromolyn (10 - 15 mins before exercise)

Long acting:
- Formoterol (inhaled, long-acting, lasts 10 hours, starts working in 1-3 mins., treats long-term control of asthma)
- Salmeterol (inhaled, long-acting, lasts 12 hours, starts working in 10-20 mins., treats long-term control of asthma)
- Terbutaline (oral, lomg-acting, treats long-term control of asthma)

Facts:
- work on bronchial smooth muscle and promote bronchodilation
- do not give to patients with tachydysrythmias, hyperthyroidism, hypertension, angina, or heart disease
- beta blockers will reduce effects (do the opposite, especially nonselective that work on muscles and organs)
- MAOIs will increase effects
- do not use salmeterol more than once every 12 hours
- tachycardia, tremors, palpitations may occur

Q

Methylxanthines

A
  • Aminophylline
  • Theophylline

Facts:
- bronchodilators
- long-term control of asthma
- do not give to patients with peptic ulcer disease
- phenobarital and phenytoin decrease theophylline
- caffeine, furosemide, cimetidine, fluorquinolones, acetaminophen, and phenylbutazone falsely elevate therapeutic levels
- toxicity can cause tachycardia, tachypnea, and seizures
- toxicity: stop parental infusion, activated charcoal to decrease absorption in oral overdose, lidocaine for dysrhythmias, diazepam to control seizures

- PREVENT acute bronchospasms, not treat
- manage allergen or exercise induced asthma
- treats COPD
- do not give to patients with peanut allergy or soy
- caution with patients who have BPH and narrow-angle glaucoma

Intravenous:
- hydrocortisone sodium succinate

Facts:
- short term IV agents for status asthmaticus
- short term oral agents for symptoms following an acute attack
- long term oral agents for chronic asthma
- long term inhalation use for prophylaxis of asthma
- patients with diabetes may need higher doses
- don’t stop abruptly
- can cause hyperglycemia, peptic ulcers, insomnia, fluid retention, inceased appetite
- give with meals

Q

Leukotriene Modifiers

A
  • Montelukast (for ages 1+)

  • Zileutron (for ages 12+)

Facts:
- used for long-term management of asthma
- montelukast only available as tablet or granules
- Zs: high risk for liver disease, increased warfarin effects, theophylline toxicity
