1

drugs that act by coating the wall of the GI tract and absorbing bacteria or toxins that cause diarrhea (EX: kaolin, pectin, Pepto-Bismol)

Adsorbents

2

the active ingredients in marijuana approved for clinical use to alleviate nausea & vomiting resulting from cancer treatment

Cannabinoids

3

drugs used to eliminate fecal matter; "laxative"

Carthartics

4

cerebral center lying near the medulla that causes vomiting when stimulated

Chemoreceptor Trigger Zone (CTZ)

5

drugs that act as lubricants and stool softeners used to prevent constipation

Emollients

6

"hyperolmolar laxatives" including salts or saline products, lactulose, and glycerin

Osmotics

7

"harsh" carthartics that cause water stool with abdominal cramping

Purgatives

8

drugs that promote ulcer healing by neutralizing hydrochloric acid and reducing pepsin activity; do not coat the ulcer; two types: systemic & nonsystemic

Antacids

9

thick, viscous, mucous material that provides a barrier between the mucosal lining and acidic gastric secretions; maintains the integrity of the gastric lining and is a defense against corrosive substances

Gastric Mucosal Barrier (GMB)

10

ulcer frequently occurring because of breakdown of the GMB

Gastric Ulcer

11

ulcer caused by hypersecretion of acid from the stomach passing into the duodenum because of (1) insufficient buffers to neutralize gastric acid in the stomach (2) defective pyloric sphincter or (3) hypermotility of the stomach

Duodenal Ulcer

12

inflammation or erosion of the esophageal mucosa caused by a reflux of gastric acid content from the stomach into the esophagus

Gastroesophogeal Reflux Disease (GERD)

13

popular drugs used in the treatment of gastric and duodenal ulcers that block the H2 receptors of the parietal cells in the stomach, thus reducing gastric acid secretion and concentration (EX: ranitidine, cimetidine, axid)

Histamine2 Receptor Antagonists (H2 Blockers)

14

acid released by the parietal cells of the stomach influenced by histamine, gastrin & acetylcholine

Hydrochloric Acid

15

broad term used for an ulcer occurring in the esophagus, stomach or duodenum within the upper GI tract

Peptic Ulcer

16

ulcer resulting from the reflux of acidic gastric secretions into the esophagus as a result of a defective or incompetent cardiac sphincter

Esophageal Ulcer

17

digestive enzyme activated at a pH of 2

Pepsin

18

ulcer following a critical situation such as extensive trauma or major surgery (burns, cardiac surgery)

Stress Ulcer

19
