Study Notes

Xanthine Derivatives

Mechanism of action: Increase cAMP levels, leading to bronchodilation and diuresis
Not a xanthine derivative: Beta-agonists
Not a therapeutic use: Treating hypertension
Potential side effect: Diuretic effect, nausea, vomiting, and tremors

Beta-Agonists

Therapeutic use in addition to relief of bronchospasm: Prevention of exercise-induced bronchospasm
Not a therapeutic use of bronchodilators: Treating hypertension
Main function: Stimulating beta-2 receptors, leading to bronchodilation and relaxation of airway smooth muscle

Other Medications

Antileukotrienes (LRTAs): Mechanism of action: Inhibiting the production of leukotrienes, which cause bronchoconstriction
Inhaled corticosteroids: Potential side effect: Oropharyngeal candidiasis
Medications associated with trembling, particularly in the hands: Beta-agonists
Medication used to prevent bronchoconstriction by binding to ACh receptors: Anticholinergics
