Asthma and COPD are primarily treated with ___________ as the antiinflammatory agents
and____________ as the bronchodilators Correct-glucocorticoids; beta2 agonists
how do bronchodilators work with asthma and COPD Correct-symptomatic relief,
therefore they do not alter the underlying inflammation that accompanies the disease
Specific antiinflammatory effects of glucocoritcoids Correct-decreased release of
inflammatory mediators leukotrienes and histamine, decreased presence of eosinophils and
leukocytes in the bronchi, decreased edema
Leukotriene Modifiers Correct-
Leukotriene Modifiers reduce inflammation Correct-prevent smooth muscle contraction or
bronchial airways, decreasing mucous secretion, and reduce vascular permeability
inhaled beta2 agonists activate Correct-receptors in the smooth muscle of the lung, which
promotes vasodilation

SABAs examples Correct-Short-acting beta agonist rescue treatment; albuterol,
levalbuterol, pirbuterol, terbutaline, and metaproterenol
LABAs examples Correct-Long-acting beta agonist; arformoterol, formoterol, and
salmeterol
Decongestant agents Correct-are vasoconstriction (sympathomimetics) agents used to
shrink swollen nasal mucous membranes and relieve nasal stuffiness
drugs that suppress harmful or non-productive coughs Correct-antitussives
two types of antitussives Correct-opioid (codeine and hydrocodone) and nonopioid
(dextromethorphan)
how do opioid antitussives work Correct-direct action in the CNS medulla, drying effect on
mucosa of the respiratory tract
how do nonopioid antiussives work Correct-no analgesic properties,

benzonatate what is it and how does it work Correct-nonopioid antitussive, suppresses
cough reflex by numbering stretch receptors in the respiratory tract which prevents
stimulation of the medulla
reduce viscosity of secretions, allowing the ejection of excessive mucus Correct-
expectorants
most common expectorant OTC Correct-guaifenesin
drugs that relate directly with mucus to make it more watery Correct-mucolytics MAKES
THE COUGH MORE PRODUCTIVE
Acetylcysteine Correct-mucolytic adminsitered with a nebulizer,
side effects and AE of acetylcysteine Correct-may trigger bronchospasm, nausea,
vomitting, stomatitis (oral ulcers), runny nose; bad smell because it contains sulfer
