Disease background and treatment goals

GERD occurs when reflux of stomach contents causes troublesome symptoms or complications. Reducing acidity can reduce injury and discomfort, but acid suppression does not remove every cause of reflux. [W]

How the medicines relate to the condition

Antacids — Short-term symptom relief

Neutralize stomach acid already present. Symptom relief is not confirmation of the diagnosis. [C1]

H2 blockers — Acid suppression

Reduce stomach acid production. Treatment intensity depends on the diagnosis. [C1]

Omeprazole / PPIs — Acid suppression / healing

Suppress gastric acid secretion through proton pump inhibition. Review interactions and ongoing need. [C2]

Understanding selection and combination treatment

Antacids help with mild symptoms. H2 blockers and proton pump inhibitors reduce acid production; PPIs can heal reflux-related oesophageal injury more effectively than H2 blockers. Lifestyle measures and reassessment still matter. [C1]

Monitoring, risks and reassessment

Persistent symptoms, difficulty swallowing or suspected bleeding need assessment rather than indefinite self-treatment. Omeprazole can interact with other medicines. The reason and duration for acid suppression should be reviewed. [C2]

Questions for a clinician or pharmacist

1. Are we treating occasional symptoms or confirmed oesophageal injury?

2. When should continued symptoms lead to further investigation?
