What are the treatments for diseases of the lower respiratory tract? - correct answer
✔✔*Bronchodilators: *
Beta-adrenergic agonists
Xanthine derivatives
Anticholinergics
*Non-Bronchodilators: *
Leukotriene receptor antagonists (LTRAs)
Corticosteroids
What is the function of beta-adrenergic agonists? - correct answer ✔✔Quickly reduce airway
constriction and restore airflow.
Sympathomimetic - Imitate the effects of norepinephrine on beta receptors.
Categorized by their onset of action:
Short-Acting (SABA) - Symptomatic treatment
Long-Acting (LABA) - Prophylactic treatment
What is the function of xanthine derivatives? - correct answer ✔✔Prevention of asthmatic symptoms
and COPD (not for relief of acute asthma attacks).
What are the contraindications of xanthine derivatives? - correct answer ✔✔Uncontrolled cardiac
dysrhythmias
Seizure disorders
Hyperthyroidism
Peptic ulcers
What are the adverse effects of xanthine derivatives? - correct answer ✔✔*Mild:* N/V, anorexia, GI
reflux
*Severe:* Tachycardia, extrasystole, palpitations, ventricular dysrhythmias
*Toxicity:* Requires laboratory monitoring of drug levels.
What is the function of leukotriene receptor antagonists (LTRA's)? - correct answer ✔✔Inflammation in
the lungs is blocked.
Prevent smooth muscle contraction of bronchioles.
