Summary
Levalbuterol has reached the approved stage (maximum clinical phase 4) for at least one indication, so its use in Peripheral Artery Disease (PAD) would be drug repurposing rather than first-in-human development. This does not mean it is approved for Peripheral Artery Disease (PAD). ClinicalTrials.gov lists 1 registered trial linking Levalbuterol to Peripheral Artery Disease (PAD): 1 is terminated, withdrawn, suspended or of unknown status. None of the registered studies carries a drug-development phase label, which is typical for behavioural, device and supplement protocols. It plans or enrolled 500 participants. Registered activity dates to 2017. No published literature item is linked to Levalbuterol and Peripheral Artery Disease (PAD) 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 Peripheral Arterial Disease ranks 292 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: Progressive disease; spontaneous improvement rare; limb ischaemia worsens in 25-30% over 5 years; major adverse limb events (MALE) in 10-15%/year in advanced PAD; major amputation in 5-10% at 5 years without revascularisation.

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trial scores by status (recruiting / active / enrolling 3, completed 2.5, not yet recruiting 2, unknown 1, terminated / withdrawn / suspended 0.5) plus a phase bonus (phase 3-4 +2, phase 2 +1, phase 1 +0.5).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

Published literature
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 ADRB2. The tier describes how well the drug-disease link is documented, not how well the drug works.
Frequently asked questions
Is Levalbuterol approved for Peripheral Artery Disease (PAD)?
Levalbuterol has reached the approved stage (maximum clinical phase 4) for at least one indication, so its use in Peripheral Artery Disease (PAD) would be drug repurposing rather than first-in-human development. This does not mean it is approved for Peripheral Artery Disease (PAD). Approval status for the specific indication should always be confirmed with the relevant regulator and prescribing information.
Is Levalbuterol in clinical trials for Peripheral Artery Disease (PAD)?
ClinicalTrials.gov lists 1 registered trial linking Levalbuterol to Peripheral Artery Disease (PAD): 1 is terminated, withdrawn, suspended or of unknown status. None of the registered studies carries a drug-development phase label, which is typical for behavioural, device and supplement protocols. It plans or enrolled 500 participants. Registered activity dates to 2017.
What does the evidence show for Levalbuterol in Peripheral Artery Disease (PAD)?
Trials of Levalbuterol in Peripheral Artery Disease (PAD) 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 ADRB2. The tier describes how well the drug-disease link is documented, not how well the drug works.
