Can Omeprazole Make Reflux Worse?
Introduction to Omeprazole and Reflux
Omeprazole is a proton pump inhibitor (PPI) commonly prescribed to reduce stomach acid production and treat conditions like gastroesophageal reflux disease (GERD). However, there is ongoing debate about whether omeprazole can sometimes exacerbate reflux symptoms.
Omeprazole's Effectiveness in Treating Reflux Symptoms
Positive Impact on Sensitive Oesophagus
Research indicates that omeprazole can significantly improve symptoms in patients with a "sensitive oesophagus," a condition where patients experience reflux symptoms despite normal acid levels. In a study involving 18 patients, those with a positive symptom index (SI) showed marked improvements in symptom frequency, severity, and reduced antacid consumption when treated with omeprazole compared to a placebo1. This suggests that for certain patients, omeprazole is effective in managing reflux symptoms.
Comparison with Ranitidine
A comparative study between omeprazole and ranitidine in patients with reflux oesophagitis demonstrated that omeprazole provided faster and more pronounced relief of symptoms. Patients treated with omeprazole showed higher cumulative healing rates and quicker symptom relief compared to those treated with ranitidine3. This further supports the efficacy of omeprazole in treating reflux symptoms.
Omeprazole and Respiratory Symptoms
Lack of Improvement in Pulmonary Parameters
In patients with severe airway hyperresponsiveness and gastro-oesophageal reflux, omeprazole did not show beneficial effects on pulmonary parameters. Despite its effectiveness in reducing acid reflux, omeprazole did not improve airway hyperresponsiveness or other pulmonary symptoms in patients with asthma and chronic obstructive pulmonary disease (COPD)2. This indicates that while omeprazole can alleviate reflux symptoms, it may not necessarily improve associated respiratory conditions.
Conclusion
Overall, omeprazole appears to be effective in reducing reflux symptoms, particularly in patients with a sensitive oesophagus and those with reflux oesophagitis. However, its benefits do not extend to improving pulmonary symptoms in patients with severe airway hyperresponsiveness. There is no substantial evidence from the provided studies to suggest that omeprazole makes reflux worse. Instead, it generally improves symptoms in the majority of patients. Further research is needed to explore the long-term effects of omeprazole and its impact on different patient populations.

Double blind cross-over placebo controlled study of omeprazole in the treatment of patients with reflux symptoms and physiological levels of acid reflux--the "sensitive oesophagus".
Omeprazole improves symptoms in 11 out of 18 patients with normal acid reflux levels, particularly in those with a positive symptom index, supporting the theory that these patients have a "sensitive" oesophagus.
RCT
Highly CitedNo effects of high-dose omeprazole in patients with severe airway hyperresponsiveness and (a)symptomatic gastro-oesophageal reflux.
High-dose omeprazole does not improve pulmonary symptoms and function in patients with asthma and chronic obstructive pulmonary disease, despite reducing acid reflux.
RCTHighly CitedOmeprazole and ranitidine in treatment of reflux oesophagitis: double blind comparative trial
Omeprazole 40 mg in the morning is more effective than ranitidine 150 mg twice daily for short-term treatment of reflux oesophagitis, with faster symptom relief and improved mucosal appearance.
RCTHighly CitedOmeprazole v ranitidine for prevention of relapse in reflux oesophagitis. A controlled double blind trial of their efficacy and safety.
Daily omeprazole 20 mg every morning is a safe and highly effective maintenance treatment for preventing relapse of reflux oesophagitis over 12 months, while weekend omeprazole and daily ranitidine are ineffective.
RCTHighly CitedComparison of outcomes twelve years after antireflux surgery or omeprazole maintenance therapy for reflux esophagitis.
Antireflux surgery is superior to omeprazole in controlling overall GERD symptoms, but post-fundoplication complaints continue after surgery.

Nocturnal acid breakthrough (NAB) is common with omeprazole treatment, potentially contributing to oesophageal damage and chronic lesions.

Adding sodium alginate to omeprazole improves heartburn resolution in Japanese patients with nonerosive reflux disease compared to omeprazole alone.
RCTHighly CitedEffect of Omeprazole on Acid Gastroesophageal Reflux and Gastric Acidity in Preterm Infants With Pathological Acid Reflux
Omeprazole effectively reduces esophageal acid exposure in premature infants with pathological acid reflux, but safety and efficacy issues require further investigation.
RCTHighly CitedDouble blind comparison of omeprazole (40 mg od) versus cimetidine (400 mg qd) in the treatment of symptomatic erosive reflux oesophagitis, assessed endoscopically, histologically and by 24 h pH monitoring.
Omeprazole 40 mg once daily provides faster symptom relief, faster and sustained healing, and greater reduction of oesophageal acid exposure than cimetidine 400 mg four times daily for treating erosive reflux oesophagitis.
RCTHighly CitedDouble-blind placebo-controlled trial of omeprazole in irritable infants with gastroesophageal reflux.
Omeprazole significantly reduced esophageal acid exposure in irritable infants with gastroesophageal reflux, but not irritability, with irritability improving over time regardless of treatment.
