Clinical use for H2 blockers
Acid reflux disease, duodenal ulcer and peptic ulcer disease
NSAID that is used for acute condition, such as pre-op anesthesia and has limited duration (<5 days) of use due to nephrotoxicity
Ketorolac
Receptors for serotonin (5HT-1) are located
Mostly in the brain, and they mediate synaptic inhibition via increased K+ conductance
Used intranasally and decreases bone resorption

H1 blocker that is also a serotonin antagonist
Cyproheptadine
COX 2 inhibitors may have reduced risk of
Gastric ulcers and GI Bleeding
Agents for reduction of postpartum bleeding
Oxytocin, ergonovine and ergotamine
Vitamin given with calcium to ensure proper absorption
Vitamin D
Agents used in treatment of carcinoid tumor
Ketanserin cyproheptadine, and phenoxybenzamine
COX 2 inhibitors should be used cautiously in pts with
Pre-existing cardiac or renal disease
5HT-3 antagonist used in chemotherapeutic induced emesis
Ondansetron, granisetron,
dolasetron and alosetron
