Linked identity set
Multiple linked identities can reflect reviewed source-sequence differences, variant entries, or precursor-like entries. Use the reference identity as the main product-context link.

| Identity match | Reference | Link review |

Interpretation boundary
The link supports product-context interpretation beside a peptide identity. It is not a measured endpoint, and it does not promote label, safety, or trial context into peptide-level endpoint truth by itself.

There appeared to be no significant effect of rhinitis, i.e., nasal congestion, on the systemic bioavailability of SYNAREL; however, if the use of a nasal decongestant for rhinitis is necessary during treatment with SYNAREL, the decongestant should not be used until at least 2 hours following dosing with SYNAREL.

Six. Provenance, scope & access
How to read, trace, cite, and reopen this profile: evidence scope, reference lineage, and reproducible data access.
Evidence scope
How to read this profile
Evidence roles stay separate before interpretation
Endpoint summaries, product-context lanes, identity links, and source references answer different questions. This boundary keeps the page useful without converting context into stronger claims than the current review layer supports.
Endpoint comparison
Traceable within endpoint context
Compare PK results only when endpoint and experimental context are compatible.
Product-context reading
Context available, not endpoint truth
Label, trial, safety, immune, and nonclinical records remain contextual unless separately extracted as an endpoint.
