1. Upper GI Disease Flashcards
Medication used to treat upper GI disease can (3)
Eliminate formed acid/neutralise stomach acid
Reduce acid secretion
Improve mucosal barrier
Which medication eliminates formed acid/neutralises stomach acid
Antacids
Which medications reduced acid secretion (2)
Hydrogen receptor pump
Proton pump inhibitors
How do medications improve mucosal barrier (2)
Eliminate helicobacter
Inhibit prostaglandin removal
Drugs that exacerbate upper GI disease (2)
NSAIDs (stop PG production and prevent healing)
Steroids - damage ulcer healing process
Mechanism of hydrogen receptor antagonists
Reduce acid production by preventing histamine activation of acid production
Limitations of hydrogen receptor antagonists
Alternative pathways still operate (that can be inhibited by ACh and gastrin)
Types of hydrogen receptor antagonists (2)
Ranitidine
Cimetidine
Types of proton pump inhibitors (3)
Omeprazole
Lansoprazole
Pantoprazole
Examples of oral diseases (3)
ROU
Lichen planus
OFG
Examples of oesophageal disorders (3)
Dysphagia
Dysmobility disorders
GORD
Definition of dysphagia
Food sticking in throat
Mechanical block/compression, may be intermittent
Types of dysphagia (3)
Functional
Dysmobility
Due to external compression
Causes of GORD (3)
Deective lower oesophageal sphincter
Impaired lower clearing
Impaired gastric emptying
GORD may cause (3)
Ulceration
Inflammation
Metaplasia
Signs/symptoms of GORD (4)
Epigastric burning - worse when lying down, bending, during pregnancy
Dysphagia - oesophagi’s, stricture, dysmobility
GI bleeding
Severe pain (mimics MI) - oesophageal muscle spasm/suspected MI
