Conclusion: Proton pump inhibitor drugs (PPIs) are effective in the treatment of dyspepsia in these trials which may not adequately exclude patients with gastro-oesophageal reflux disease (GORD). The relative efficacy of histamine H2-receptor antagonists (H2RAs) and PPIs is uncertain. Early investigation by endoscopy or H. pylori testing may benefit some patients with dyspepsia but is not cost effective as part of an overall management strategy.

Conclusion: Dentoxol mouthwashes, Plantago major extract, thyme honey extract, zinc oxide paste, vitamin B complex combined with GeneTime, and the consumption of L-glutamine are effective in diminishing the severity of OM. Pain intensity was lower with doxepin mouthwashes and diphenhydramine-lidocaine-antacid mouthwashes.
PubMed 37314054 ↗Conclusion: The clinicians and patients should be cautious about these effects so that they can avoid the serious outcomes. PPIs should be avoided for long-term use mainly in older adults unless there is a proper indication.
PubMed 32718584 ↗Conclusion: In this meta-analysis of patients with newly diagnosed glioblastoma, PPI use was associated with inferior survival outcomes. These findings suggest that PA-PPI use should be discouraged in patients with glioblastoma, since alternative agents are available and a detrimental effect cannot be excluded. Translational research studies should explore whether PPI-induced activity of ALDH mediates the potential adverse effects of PPI in glioblastoma. .

First-hand experiences, quoted verbatim. We show one positive and one negative where both exist.
“it says not to take it with antacids because doing so increases the bioavailability. ... I got some empty capsules, cut the pills in half, and put them in a capsule with part of a rolaids tablet. It wasn't quite the same but was a heck of a lot better than the dose I'd been left with.”
“I did notice that my ADD symptoms were gone for longer when I used an antacid with my Adderall.”
