Summary
Prednisolone has reached the approved stage (maximum clinical phase 4) for at least one indication, so its use in Bipolar Disorder would be drug repurposing rather than first-in-human development. This does not mean it is approved for Bipolar Disorder. ClinicalTrials.gov lists 1 registered trial linking Prednisolone to Bipolar Disorder: 1 has completed. None of the registered studies carries a drug-development phase label, which is typical for behavioural, device and supplement protocols. It plans or enrolled 3520 participants. Registered activity dates to 2011. No published literature item is linked to Prednisolone and Bipolar Disorder in the OSMF database yet, so the record rests on registry entries alone. Registry entries describe intent to study, not outcomes.
The RepurpOS disease-intelligence file for Bipolar Disorder ranks 389 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: Natural episodic pattern: untreated, median episode length 3-6 months; recurrence in 90% within 5 years; functional impairment between episodes in 30-60%; suicide risk 20-30x general population.

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trial scores by status (recruiting / active / enrolling 3, completed 2.5, not yet recruiting 2, unknown 1, terminated / withdrawn / suspended 0.5) plus a phase bonus (phase 3-4 +2, phase 2 +1, phase 1 +0.5).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.
Registered clinical trials
| NCT ID | Title | Status | Phase | Enrolment |

No publication is linked to this pair yet.
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 DGIdb, in this case via the biomarker or target CD40. The tier describes how well the drug-disease link is documented, not how well the drug works.
Frequently asked questions
Is Prednisolone approved for Bipolar Disorder?
Prednisolone has reached the approved stage (maximum clinical phase 4) for at least one indication, so its use in Bipolar Disorder would be drug repurposing rather than first-in-human development. This does not mean it is approved for Bipolar Disorder. Approval status for the specific indication should always be confirmed with the relevant regulator and prescribing information.
Is Prednisolone in clinical trials for Bipolar Disorder?
ClinicalTrials.gov lists 1 registered trial linking Prednisolone to Bipolar Disorder: 1 has completed. None of the registered studies carries a drug-development phase label, which is typical for behavioural, device and supplement protocols. It plans or enrolled 3520 participants. Registered activity dates to 2011.
What does the evidence show for Prednisolone in Bipolar Disorder?
Prednisolone has 1 completed registered trial for Bipolar Disorder but no linked publication, which usually means results are unpublished, pending, or not yet matched to this record. OSMF's existing evidence tier for this pair is A (Strong), derived from the strength of the disease association recorded in DGIdb, in this case via the biomarker or target CD40. The tier describes how well the drug-disease link is documented, not how well the drug works.
