All meds MoA Flashcards
Proton pump inhibitor
decrease acid secretions by binding to H+,K-ATPase enzyme
h2 receptor antagonist
block h2 receptors in parietal cells to decrease acid production in daytime and nocturnal
antacids
react with gastric acids to produce neutral salt, alter systemic pH, EXCEPT FOR BICARBONATE
bismuth compounds
stimulate mucosal bicarbonate and prostaglandin production, inhibit h.pylori from adhering to tissue
sucralfate
stimulate mucus, bicarbonate and prostaglandin secretion, coat stomach to form barrier
1st gen receptor antagonist
block main histamine receptors
2nd gen h1 receptor agonist
compete with histamine for h1 receptor in peripheral
intranasal corticosteroid
inhibit mast cells, microphages and inflamm mediators, vasoconstriction
pseudoephedrine
activate alpha-adrenergic receptors, cause vasoconstriction in nasal mucosa
nonopioid antitussive
act on cough center in medulla
guaifenesin
(expectorant) irritate respiratory tract, loosen and thin secretion
acetylcystine
(mucolytic) breakdown proteins in mucus to make thinner
beta2 adrenergic agonist
bind to beta2 adrenergic receptors in bronchial smooth muscle to cause bronchodilation
anticholinergic
block cholinergic receptors in bronchial smooth muscle, decrease nasal hypersecretion
corticosteroid
decrease inflammatory and immune response
