Respiratory Flashcards
(136 cards)
1
Q
What do adrenergic drugs stimulate?
A
beta 2- adrenergic receptors of the sympathetic nervous system
2
Q
What are some side effects of beta 2- adrenergic drugs?
A
tachycardia, heart palpitations, tremors, and angina with those with compromised cardiac blood vessels.
3
Q
What disorders are inhaled anticholinergics used for?
A
those with COPD
4
Q
What are the expected actions of anticholinergics?
A
inhibit acetylcholine, which causes vasoconstriction of the bronchioles and blocks the stimulation of parasympathetic receptors.
5
Q
How do glucocorticoids help chronic asthma?
A
They suppress the immune system including decreasing inflammation in the airway by preventing the release of leukotrienes, prostaglandins, and histamine, which mediate inflammation.
6
Q
What can mast cell stabilizers be used for?
A
Allergic rhinitis and chronic allergies.
7
Q
Which generation antihistamines caused sedation?
A
First gen, the older of two types
8
Q
What can first gen antihistamines be used for?
A
insomnia, allergic and anaphylactic reactions
9
Q
What receptors do antihistamines bind to?
A
H1 receptors to block the release of histamine
10
Q
What are second-gen antihistamines used for?
A
chronic and/or idiopathic urticaria
11
Q
Why don’t second-gen antihistamines cause drowsiness?
A
they antagonize histamine effects without binding to or inactivating histamine like first-gen do
12
Q
What are sympathomimetics for?
A
allergic rhinitis, sinusitis, and common cold.
13
Q
What happens if a drug like sympathomimetics bind to alpha one-adrenergic receptors?
A
causes vasoconstriction
therefore nasal turbinates shrink, and relieves nasal congestion
14
Q
What are antitussives used for?
A
Chronic nonproductive coughing related to allergies and other upper respiratory conditions
15
Q
What is the pharmacologic action of opioid and nonopioid antitussives?

Suppress the cough reflex in the brain
16
Q
What are expectorants used to treat?
A
Colds, other respiratory infections, and bronchitis to remove expectorants.
17
Q
How does expectorants work?
A
reduces surface tension of secretions making it easy to cough out of the lungs and drain
18
Q
Beta2 agonists and methylxanthines cause what in the airway?
A
cause bronchodilation by relaxing bronchial smooth muscle
19
