Summary
Epinephrine Bitartrate has reached the approved stage (maximum clinical phase 4) for at least one indication, so its use in Interstitial Cystitis / Bladder Pain Syndrome (IC/BPS) would be drug repurposing rather than first-in-human development. This does not mean it is approved for Interstitial Cystitis / Bladder Pain Syndrome (IC/BPS). ClinicalTrials.gov lists 1 registered trial linking Epinephrine Bitartrate to Interstitial Cystitis / Bladder Pain Syndrome (IC/BPS): 1 is currently recruiting. None of the registered studies carries a drug-development phase label, which is typical for behavioural, device and supplement protocols. It plans or enrolled 5 participants. Registered activity dates to 2024. No published literature item is linked to Epinephrine Bitartrate and Interstitial Cystitis / Bladder Pain Syndrome (IC/BPS) 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 Interstitial Cystitis ranks 50 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: Partial spontaneous remission in 20-30% at 2 years; complete resolution rare; chronic pain condition with significant disability; no biomarker-defined diagnosis complicates studies.

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trial scores by status (recruiting / active / enrolling 3, completed 2.5, not yet recruiting 2, unknown 1, terminated / withdrawn / suspended 0.5) plus a phase bonus (phase 3-4 +2, phase 2 +1, phase 1 +0.5).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
Recorded mechanism or class: agonist.
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 ADRB3. The tier describes how well the drug-disease link is documented, not how well the drug works.
Frequently asked questions
Is Epinephrine Bitartrate approved for Interstitial Cystitis / Bladder Pain Syndrome (IC/BPS)?
Epinephrine Bitartrate has reached the approved stage (maximum clinical phase 4) for at least one indication, so its use in Interstitial Cystitis / Bladder Pain Syndrome (IC/BPS) would be drug repurposing rather than first-in-human development. This does not mean it is approved for Interstitial Cystitis / Bladder Pain Syndrome (IC/BPS). Approval status for the specific indication should always be confirmed with the relevant regulator and prescribing information.
Is Epinephrine Bitartrate in clinical trials for Interstitial Cystitis / Bladder Pain Syndrome (IC/BPS)?
ClinicalTrials.gov lists 1 registered trial linking Epinephrine Bitartrate to Interstitial Cystitis / Bladder Pain Syndrome (IC/BPS): 1 is currently recruiting. None of the registered studies carries a drug-development phase label, which is typical for behavioural, device and supplement protocols. It plans or enrolled 5 participants. Registered activity dates to 2024.
What does the evidence show for Epinephrine Bitartrate in Interstitial Cystitis / Bladder Pain Syndrome (IC/BPS)?
Trials of Epinephrine Bitartrate in Interstitial Cystitis / Bladder Pain Syndrome (IC/BPS) are registered but none has completed, so there is no outcome evidence from those studies yet; the record is a signal of research interest. 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 ADRB3. The tier describes how well the drug-disease link is documented, not how well the drug works.
