# Omeprazole vs Esomeprazole in Nigeria: is the newer ulcer drug worth the extra naira?

**The short answer:** For most heartburn and ulcer treatment, omeprazole does the job at a fraction of the price. Esomeprazole — chemically the refined half of the same molecule — suppresses acid slightly more strongly milligram-for-milligram, which occasionally matters for stubborn reflux or healing erosive damage. Start cheap; step up only if symptoms genuinely persist.

These two are closer than their marketing suggests: esomeprazole is literally one of the two mirror-image forms that make up omeprazole, isolated and sold separately. The refinement gives modestly stronger and more consistent acid suppression at equivalent doses, and studies show slightly better healing rates for badly eroded oesophagus — but for the everyday burning chest, sour belches, or ulcer pain that sends Nigerians to the chemist, both work well.
Two cautions matter more than the choice between them. First, 'ulcer' pain that keeps returning deserves an H. pylori test — the bacteria behind most true ulcers — because eradicating it beats years of acid tablets. Second, these drugs are for courses, not for life; long-term unsupervised daily use has real downsides, so recurring symptoms are a reason to see a doctor, not to keep buying packs.

## Reach for Omeprazole when…

- First treatment of heartburn, gastritis, or an ulcer course
- Budget matters — the difference funds the rest of your treatment
- It's part of an H. pylori combination a clinician prescribed

## Reach for Esomeprazole when…

- A proper omeprazole course genuinely didn't settle symptoms
- Endoscopy showed erosive damage a doctor wants healed harder
- Night-time reflux keeps breaking through

## I've taken ulcer drugs for months and the pain keeps coming back — what now?

Get tested for H. pylori. Most recurring 'ulcer' in Nigeria is driven by this bacteria, and a one-to-two-week eradication combination (two antibiotics plus one of these acid drugs) can end the cycle for good. Also watch NSAID painkillers like diclofenac and ibuprofen, which quietly cause ulcers.

## When should I take it?

30–60 minutes before the first meal of the day. Both drugs need to be in your system before the stomach's acid pumps switch on with food — swallowing them after a meal wastes much of the dose.
