Respiratory Flashcards
B2 agonists short acting - acute management
Salbutamol
albuterol
terbutaline
metaproterenol
B2 agonists long acting - used for prophylaxis
salmeterol
formeterol
stimulate B2 receptors
increase cAMP
decrease muscle tone
bronchial smooth muscle relaxation
Salbutamol
albuterol
terbutaline
metaproterenol
salmeterol
formeterol
ADR: usually have minimal to no ADR, fine tremors, dizziness, restlessness, agitation
B2 agonists
antagonize the actions of leukotrienes
inhibit brinchoconstriction
decrease microvascular leakage and mucus production
inhibit influx of basophils and lymphocytes into airways
leukotriene modulators (LOX)
leukotriene receptor blockers
montelukast
zafirlukast
leukotriene synthesis inhibitors
zileuton - blocks LOX
Bronchodilation CNS stimulant CVS stimulant inhibit PD4 in bronchial mucosa antagonism of adenosine receptors
Theophylline
Theobromine
caffeine
all are xanthine deriavtives
block M3 receptors
increase mucociliary clearance
used in nebulizers
ipratropium
ocitropium
tiotropium
atropine cannot use cause it blocks mucus clearance
Glucocorticoids
beclomethasone
fluticasone
triamicinolone
budesonide
modulate cytokine and chemokine production
inhibit eicosanoid synthesis
inhibit accumulation of mast cells
decrease vascular permeability
Glucocorticoids
beclomethasone
fluticasone
triamicinolone
budesonide
ADR: most common is dysphonia and oral candidiasis
beclomethasone
fluticasone
triamicinolone
budesonide
mast cell stabilizers from degranulation
inhibit further release of inflammatory
mediators from mast cells
sodium cromoglicate
nedocromil sodium
dry antitussives - opioids
act on medullary anti cough center
codeine
pholcodeine
morphine
dry antitussives - non opioid
act on medullary anti cough center
noscapone
dextromethorphan
