Summary
Esomeprazole Magnesium has reached the approved stage (maximum clinical phase 4) for at least one indication, so its use in Rheumatoid Arthritis would be drug repurposing rather than first-in-human development. This does not mean it is approved for Rheumatoid Arthritis. No registered clinical trial in this database tests Esomeprazole Magnesium specifically in Rheumatoid Arthritis. The evidence below comes from published literature only, so any clinical signal has not yet been tested prospectively against this condition in a registered study. The literature layer holds 2 publications for this pair: 2 clinical trial publications. Publication years run from 2011 to 2014. These are primary trial reports rather than syntheses, so results have not yet been pooled or graded independently.
The RepurpOS disease-intelligence file for Rheumatoid Arthritis ranks 544 candidate therapeutics from Open Targets, ChEMBL, DGIdb and PubMed; only a minority carry direct clinical evidence, and this page covers one of those. Spontaneous remission context recorded for the condition: 11% achieve drug-free remission (DFR) at median 74 months; most cohorts show 10-15% DFR ceiling.

How the evidence score is calculated
- Each registered trial scores by status (recruiting / active / enrolling 3, completed 2.5, not yet recruiting 2, unknown 1, terminated / withdrawn / suspended 0.5) plus a phase bonus (phase 3-4 +2, phase 2 +1, phase 1 +0.5). The trial component is capped at 30.
- Each literature item scores by design (Cochrane review 5, meta-analysis 4, systematic review 3, RCT 3, clinical trial publication 2, curated reference 1.5, other PubMed record 1). The literature component is capped at 30.
- The existing evidence tier adds 15 (A / Strong), 10 (B / Moderate), 5 (C / Preliminary) or 0 (D / Anecdotal).
- Agents approved for any indication (max clinical phase 4) add 5, because an approved agent has an established safety profile that lowers the barrier to repurposing trials.
- The score ranks what has been studied, not what works. It does not read effect sizes or directions of effect.

Mechanism and notes
No mechanism of action is recorded for this pair in the source databases.
OSMF's existing evidence tier for this pair is A (Strong), derived from the strength of the disease association recorded in Open Targets and ChEMBL. The tier describes how well the drug-disease link is documented, not how well the drug works.
Frequently asked questions
Is Esomeprazole Magnesium approved for Rheumatoid Arthritis?
Esomeprazole Magnesium has reached the approved stage (maximum clinical phase 4) for at least one indication, so its use in Rheumatoid Arthritis would be drug repurposing rather than first-in-human development. This does not mean it is approved for Rheumatoid Arthritis. Approval status for the specific indication should always be confirmed with the relevant regulator and prescribing information.
Is Esomeprazole Magnesium in clinical trials for Rheumatoid Arthritis?
No registered clinical trial in this database tests Esomeprazole Magnesium specifically in Rheumatoid Arthritis. The evidence below comes from published literature only, so any clinical signal has not yet been tested prospectively against this condition in a registered study.
What does the evidence show for Esomeprazole Magnesium in Rheumatoid Arthritis?
The record for Esomeprazole Magnesium in Rheumatoid Arthritis rests on 2 publications without a registered trial. This is a lead for hypothesis generation, not evidence of efficacy. OSMF's existing evidence tier for this pair is A (Strong), derived from the strength of the disease association recorded in Open Targets and ChEMBL. The tier describes how well the drug-disease link is documented, not how well the drug works.
