17 Cards in this Set

  • Front
  • Back
Antihistamines Uses?
allergic reactions, induce sleep, relieve nausea, prevent motion sickness
Antitussives Uses?
suppress cough
Antitussives (opioids)?
codeine added
WATCH for resp depression!!
Antitussives (non-opioids)?
used to supress cough that's non-productive, painful, or prevents sleep
are used to relax the smooth muscle in the bronchi & bronchioles in conditions like asthma, bronchitis & emphysema
Adrenergic bronchodilators: beta 2?
adrenergic receptors in smooth muscles of bronchi & bronchioles-stimulate increased production of cAMP, which induces relaxation of smooth muscle & lets airways dilate.
Adrenergic bronchodilators: beta 1?
adrenergic receptors as well, which results in cardiac stimulation
Adrenergic bronchodilators: Selective beta 2?
adrenergic agonists produce bronchodilation w/ minimal sx of cardiac stimulation. (reason they're “selective”).
Anticholinergic bronchodilators?
Ipratropium (Atrovent)don't relieve acute bronchoconstriction, but enhance bronchodilating effects adrenergics. SE: GI distress, cough, hypotension.
increase cAMP, by inhibiting enzyme that breaks it down. cause mild diuresis by increasing blood flow to kidneys. theophylline (Theo-Dur)
Theophylline (Theo-Dur)?
monitor serum drug levels regularly (drugs narrow safety and toxicity margin; can cause fatal arrhythmias. Therapeutic levels are 10 – 20 mcg / ml
stimulate resp secretions and thin mucus for easier expectoration
Inhaled Corticosteroids?
reduce airway inflammation, increase # & sensitivity of beta- 2 receptors to adrenergic bronchodilators
Leukotriene Modifiers?
prevent asthma sx by suppressing synthesis of leukotrienes or blocking their receptors
Mast Cell Stabilizers?
reduce sx of inflammation in the resp tract by preventing release of histamine from mast cells-Cromolyn (Intal)
Asthma Prevention Meds?
Cromolyn (Intal), Montelukast (Singular), & Zafirkulast (Accolate)
react directly w/ mucus-makes thinner (easier to expectorate).
