lilley ch 50 acid-controlling drugs Flashcards
3 divisions of stomach
cardiac
pyloric
gastric
3 cells of gastric gland
parietal
chief
mucous
cells from gastric gland that produce and secrete hydrochloric acid. Site of action to treat acid-related
disorders
parietal cells
cells from gastric gland that secrete pepsinogen which becomes pepsin when activated by pepsin. Pepsin
breaks down protein
chief
cells from gastric gland that secrete mucous that serves
as a protective coating against digestive actions
mucous
substance secreted from parietal cells that aids in the proper digestion of food and defenses against microbial
infection via the GI tract
hydrochloric acid (HCl)
what foods/drinks stimulate parietal cells to secrete HCl (4)
food
caffeine
chocolate
alcohol
Hyperproduction of hydrochloric acid is stimulated
by what two things
large fatty meals
emotional stress
acid-related disease: Gastric or duodenal ulcers that involve digestion of the GI mucosa by the enzyme pepsin
peptic ulcer disease
what med treats H pylori
PPIs and combo of antibiotics
what factors may lead to stress-related mucosal damage (6)
- decreased blood flow
- mucosal ischemia
- hypoperfusion
- reperfusion injury
- NG tube
- ventilator
2 meds given to prevent stress-related mucosal damage
histamine receptor-blocking drug
PPIs
3 types acid-controlling drugs
antacids
H2 antagonists
PPIs
type of acid-controlling drug:
-Basic compounds used to neutralize stomach acid
-Salts of aluminum, magnesium, calcium, and/or
sodium
antacids
what minerals can make you constipated (2)

calcium
what mineral counteracts constipation
