|
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
|
|
|
Bronchodilators?
|
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.
|
|
|
Xanthines?
|
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
|
|
|
Expectorants?
|
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)
|
|
|
Mucolytics?
|
react directly w/ mucus-makes thinner (easier to expectorate).
