Omeprazole

Conclusion: There is limited high-quality evidence favouring any specific widely used drug over the others in the management of high-output stoma. Evidence, however, is weak due to inconsistent definitions, risk of bias and poor methodology in the existing studies. We recommend the development of validated core descriptor and outcomes sets, as well as patient-reported outcome measures.

Conclusion: There were no significant differences in outcomes between other subgroups, including tolerability. Based on these results, a high dose of esomeprazole is recommended for GERD treatment and control in adults.

Conclusion: Although the pooled OR of vitamin B12 deficiency was slightly increased in PPI users, but there was significant heterogeneity, and the pooled OR was too low to imply an association clearly. Better-designed prospective studies in long-term users may clarify the issue.

Conclusion: Using twice-daily PPIs is more effective in increasing efficacy increasing once-daily PPI dosage. Omeprazole and lansoprazole (30 mg) and 20 mg of esomeprazole rabeprazole are functionally equivalent.
