Medical mx of GORD?

Prescribe antacids and alginates
H2- receptor antagonists
PPIs
How do antacids and alginates work?
Form viscous gel that floats on stomach surface to prevent reflex
Relieve mild symptoms
What are commonly used antacids and alginates in mx of GORD?
Gaviscon
Peptac
How do H2- receptor antagonists work?
Block H2 histamine receptors on gastric parietal cells–> reduced proton pump activity
What is the most commonly used H2- receptor antagonist?
Ranitidine
Why is the use of H2-receptor antagonists in management of GORD limited?
Reduced efficacy within 2-6 weeks of initiation due to tachyphylaxis
What is the gold standard treatment of moderate to severe GORD
PPIs
How do PPIs work?
Inhibit H/K proton pump on gastric parietal cells, significantly increasing gastric pH
When should PPIs be taken?
Morning at least 30 minutes before first meal of the day
What PPI is generally prescribed and why?
Omeprazole- cheapest
No difference between different PPIs
How should PPIs be prescribed for GORD?
Full dose OD for 4-8 weeks e.g. omeprazole 40mg
If unresponsive, either increase PPI (e.g. 40mg BD) or switch to alternate PPI
If unresponsive refer for OGD
How should you take patients off PPIs?
Try off period after 4-8 weeks
In those whose sx recur (majority), restart PPI and titrate down to lowest effective dose
Some its may only need as a “pill in pocket”
