NSG-318: Introduction to Pharmacology
When administering Nexium, or any Proton Pump Inhibitor, what should you observe?
Observe hepatic function - this elevates AST, ALT
Should Nexium be taken with food or on an empty stomach?
On an empty stomach - this allows the stomach lining to be coated. Taking this with food blocks
this process.
What is the mode of action of Sucralfate (Carafate)?
Combines with protein to form a thick paste covering ulcer protecting ulcer from acid and
pepsin. This does not decrease acid production or neutralize acid
What is the mode of action of Diphenoxylate with Atropine (Lomotil) and what are some of
the side effects?
Anticholinergic properties: dries out, causes urinary retention; atropine decreases cramping,
motility and hypersecretions
Antihistamine used to treat allergic rhinitis, the common cold, cough, sneezing, pruritus,
urticaria, and to prevent motion sickness
Diphenhydramine (Benadryl)
What is the most common side effect of Benadryl?
