Q

CLINICAL PHARMACOLOGY – Leukotriene Inhibitor
• Mechanism of Action
– Selectively binds to airway cysteinyl leukotriene receptors blocking their stimulation by their endogenous
ligands (LTC4, LTD4, LTE4) which are released by mast cells and eosinophils

A

montelukast

18
Q

instead of pt using beta 2 agonist and steroids, if put on this drug it can reduce adverse side effects of the other drugs that could have serious complications

19
Q

serves as chemotaxic (recruitment of immune cells) mediators

20
Q

by blocking leukotriene what happens to immune system

A

immune system is unable to respond –> therefore flu symptoms are created

21
Q

CONSEQUENCE of thrombocytopenia

22
Q

thrombocytopenia

A

platelet reduction in circulation

23
Q

erythema nodosum

A

development of redness, manifested in arms and shin

24
Q

DRUG INTERACTIONS

• None involving ocular therapeutics

A

montelukast drug interaction

25
short acting beta two agonist
number one drug to provide quick relief of symptoms in asthma
26
can produce cataracts, elevated iop, impaired wound healing, infection
steroids
27
• INDICATION – Asthma, bronchospasm, COPD • DOSING [90μg/puff] – 2 puffs q4-6h
albuterol
28
distinction b/w montelukast and albuterol
albuterol is inhaled through mouth therefore only benefits lungs; while montelukast benefits nose and lungs
29
distinction b/w montelukast and albuterol
albuterol is inhaled through mouth therefore only benefits lungs; while montelukast benefits nose
30
distinction b/w montelukast and albuterol
albuterol is inhaled through mouth therefore only benefits lungs; while montelukast benefits nose
31
• CLINICAL PHARMACOLOGY – Short Acting β2 Agonist • Mechanism of Action – Selectively stimulates β2 adrenergic receptors causing relaxa3on in airway smooth muscle
albuterol moa
32
ADVERSE EFFECTS • Common: cough, dizziness, headache SEVERE ADVERSE EFFECTS • Respiratory: paradoxical bronchospasm • CVS: hypertension, angina, MI, arrhythmias
albuterol adverse effects
33
cough due to local irritation; different cough than salmeterol???
albuterol
34
causes a paradoxical bronchospasm
albuterol
35
would u use phenylephrine to dilate on a pt taking albuterol?
no, cuz it might increase bp further; always check their bp
36
how do we remember hyper/hypotension?
think beta 2 agonist elevates bp
37
if taking too much albuterol, it can effect bp how?
increase it
38
DRUG INTERACTIONS • Amphotericins, CAIs, Steroids, Macrolides (Hypokalemia) • Macrolides, Fluoroquinolones, Azoles (QT prolongation) • Sympathomimetics (Additive)
albuterol drug interactions
39
would u use phenylephrine to dilate on a pt taking albuterol?
no cuz it might increase bp further; always check their bp
40
how do beta blockers work for treating glaucoma?
Beta-blocker eyedrops work well to reduce how much fluid is made in the eye. They lower the pressure inside the eyes by about 25%. (reduce aqhu and lower pressure)
41

Beta-blocker eyedrops work well to reduce how much fluid is made in the eye. They lower the pressure inside the eyes by about 25%. (reduce aqhu and lower pressure)
42
asthma treatment for long term control
long acting beta 2 agonist and/or corticosteroid
43
asthma treatment for quick relief of symptoms
short acting beta 2 agonist
44
unlike the cough, an adverse effect seen in ace inhibitors, this drug causes a cough due to local inflammation
albuterol
