Congestive respiratory Flashcards
acronym?
ADEMA
antitussives
decongestants
expectorants/mucolytics
antihistamines
Antitussives
- acts on
- purpose
- mechanism of action
- side effects
short term cough suppression
used with acetaminophen
questionable efficacy
decongestants
alpha 1 adrenergic agonists
stimulate nasal vasoconstriction
can cause CNS excitation (dizziness, HTN, palpitations)
may cause rebound congestion when used long term
expectorants/mucolytics
Acetylcystein: breaks disulfide bonds of mucoproteins
forming less viscous secretion
used with other decongestants and antihistamines
Guaifenesin: encourages ejection of mucous
GI upset
Antihistamines
Blocks H1 receptors
decreases nasal congestion, mucosal irritation, discharge (rhinitis, sinusitis)
able to cross blood brain barrier
newer generation much improved to CNS sedation
