What Felypressin Is

Felypressin is a synthetic peptide compound with no approved prescribing label on file. It has a molecular formula of C46H65N13O11S2 and a molecular weight of approximately 1,040.2 g/mol (PubChem CID 14257662). Because no FDA label exists for this compound, there are no established indications, dosing, or mechanism descriptions to report here. Any use of felypressin outside of registered clinical research falls outside current regulatory oversight.

Trial Footprint

Public registries list a small number of clinical trials, two in total, referencing felypressin. The available trial sample involves studies comparing dental anesthetic agents, including a completed Phase 4 trial comparing articaine and prilocaine for maxillary tooth extraction, and a completed Phase 1 trial evaluating liposomal prilocaine for maxillary infiltration anesthesia. These trials appear to examine felypressin in the context of combination dental anesthetic formulations rather than as a standalone study subject. No efficacy or safety conclusions can be drawn from trial titles or status alone.

FAQ

Is felypressin FDA approved?
No. Felypressin has no approved FDA label, and this overview reflects only registered research and identity data. It should be considered an unapproved research compound at this time.
What is felypressin used for in research?
Available trial records associate felypressin with dental anesthesia research, often alongside agents like articaine and prilocaine. Only two registered trials reference the compound, and neither establishes an approved use.
What is the molecular structure of felypressin?
Felypressin has the molecular formula C46H65N13O11S2 and a molecular weight of about 1,040.2 g/mol. It is cataloged in PubChem under CID 14257662.
Are there side effects reported for felypressin?
No adverse event report data is currently available for felypressin in the sources reviewed. This means no side effect pattern can be summarized at this time.
How many clinical trials have studied felypressin?
Public registries show two clinical trials referencing felypressin, both completed and both focused on comparative dental anesthesia. These studies do not represent dedicated efficacy trials of felypressin itself.
