What Substance P Is

Substance P is a peptide with the molecular formula C63H98N18O13S and a molecular weight of approximately 1347.6 (PubChem CID 36511). It has no FDA-approved label, no approved brand name, and no approved indications. It is classified here as an unapproved, investigational research compound, meaning any use outside registered research settings falls outside regulatory oversight.

Trial Footprint

Substance P appears in 1,147 registered clinical trials. Sampled studies span a range of contexts and stages, from a not-yet-recruiting global health research center study (NCT07582380) to a Phase 4 investigation of cerebral flow-metabolism coupling during adult surgery (NCT05941494, status unknown). Another listed study is actively recruiting participants to examine signatures of Alzheimer's disease in subjective cognitive decline (NCT07402161). These entries reflect registration activity and status at the time of data retrieval, not confirmed outcomes or established efficacy.
