Question Answer
Decongestants- examplesPseudoephedrine, phenylephrine, oxymetazoline, naphazoline
Decongestants- mechanism of actiondisplace norepinephrine from presynaptic vesicles, causes vasocontriction
Decongestants- patient precautionsHTN, CAD, do not use sustained release in children or elderly
Decongestants- adverse effectsCNS excitability, arrhythmias, HTN, increased intraocular pressure, rebound congestion
Antihistamines- examplesdiphenhydramine, chlorpheniramine, brompheniramine
Antihistamines- mechanism of actioncompetively compete with histamine for receptors blocking the action of histamine
Antihistamines- adverse effectsCNS depression, anticholinergic effects: dry eyes, dry mouth, urinary retention, constipation
Examples of non-sedating antihistaminesloratidine (claritin), certirizine (zyrtec)
Antacids- patient precautionsrenal insufficiency, watch for sodium content
Histamine-2 blockers examplescimetidine (tagamet), ranitidine (zantac), famotidine (pepcid), nizatidine (axid)
Proton pump inhibitor- examplesomeprazole (prilosec OTC)

NSAIDS- examplesaspirin, diclofenac (voltaren), diflunisal (dolobid), etodolac (lodine), ibuprofen (mortin), naproxen (aleve)
Acetaminophen- mechanism of actiondirect action on hypothalamic heat regulating center, inhibits pyrogenic cytokines
True or false: acetaminophen inhibits peripheral prostaglandin synthetase?False
Acetaminophen- indicationsfever, mild to mod pain
Acetaminophen- kineticsrapidly absorbed orally, onset 30 min, metabolized in the liver and excreted in the kidney
Acetaminophen- adverse effectsrash, fever, neutropenia, thrombocytopenia, jaundice. Side effects rare, usually dose dependent
Acetaminophen- interactionscaution with hepatic disease, increased hepatotoxicity with barbiturates, phenytoin, etoh, rifampin, warfarin
