Farm Quiz - Pulmonary Meds Flashcards
opioids to control cough
ex: codine, hydrocodone
antitussive
How do antitussives work?
what is the primary side effects?
suppress sensitivity of cough reflex at the level of the brainstem
SE: developing addiction, some degree of tolerance
How do antihistamines work?
reduce cough/sneeze by blocking the type 1 histamine (H1 receptors)
SE of antihistamines? Why is this the older version not as used?
sedation, fatigue, dizziness, incoordination
older generation: antihistamines cross BBB and active the RAS –> tremors, more sedative
How do decongestants work?
stimulates alpha 1 receptors in smooth muscle in nose –> vasoconstriction –> decreasing congestion
Ephedrine (primatene), Oyxmetazoline (Afrin), pseudoepharine (sudafed) are examples of ___
decongestants
Brompheniramine (Dimetapp), cetirizine (zyrtec), diphenhydramine (benadryl), (claratin) are examples of __
antihistamines
What are SE of decongestants
increase sympathetic response –> CNS and cardiac excitation –> headache, dizziness, increase BP and palpitations
How do mucolytics work?
decrease viscosity of respiratory secretions
mucomyst, mucosil, pulmozyne are administered via __ and are examples of ___
What are the SE?
inhaler
mucolytics
nausea/vomit, inflammation of oral mucosa
What combo of med + technique is helpful for airway clearance
mucolytics + airway clearance therapy
How do expectorants work?
facilitate production and clearance of mucus
Guaifenesin (Musinex) is an example of a ____
What are the SE?
Expectorant
minor GI disturbances
How do Bronchodilators work?
stimulate B2 receptors in the respiratory smooth muscle –> relaxation of bronchiolar smooth muscle –> bronchodilation
Ventolin (albuterol) and serevent (salmeterol) are exmaples of __
What are the SE?
B adrenergic agonists (bronchodilators)
SE: increase bronchial irritability and spasm, tolerance
