pergolide

Identity anchor

Use a stereochemically explicit structure and authoritative identifiers as the recognition anchor.

1. Which structure and stereochemical specification define pergolide in this record? definition
2. Which authoritative record supports each identifier, and do all identifiers resolve to the same chemical form? provenance

Free base versus mesylate

Record the mesylate relationship explicitly and preserve the registry entry's granularity.

1. Does the material contain pergolide free base, its mesylate salt, or a formulation containing that salt? boundary
2. Which counterion, stoichiometry, and identifier evidence establish the supplied form? measurement

Assay normalization

Every content value needs a chemical basis, sample basis, and measurement method.

1. Is the reported assay expressed as pergolide free-base equivalent or pergolide mesylate, and on an as-is or corrected basis? measurement
2. What verified composition and calculation permit conversion between the reported and required quantities? action

Purity and release

Qualification requires lot-specific impurity evidence and an applicable acceptance specification.

1. Which related substances, stereoisomers, residual solvents, and other relevant impurities were measured, with what limits? measurement
2. Which specification and certificate support this lot's claimed grade and permitted use? provenance

Qualified physical data

Treat phase, thermal behavior, and solubility as conditional observations rather than universal name-level constants.

1. For which pergolide form, purity, and conditions were phase, solubility, and thermal behavior measured? measurement
2. Does a reported thermal value describe melting, decomposition, or another transition? definition

Stability disposition

Storage limits and retest decisions must be supported for the material form and container involved.

1. What evidence establishes temperature, light, moisture, container, and retest requirements for this pergolide material? provenance
2. Does the recorded exposure history permit continued use, or require quarantine and analytical reassessment? action

Activity evidence

Record dopamine and other receptor evidence with assay context rather than treating agonist labels as interchangeable potency values.

1. Which dopamine and serotonin receptor activities are established for pergolide, in which species and assays? measurement
2. Does each result measure binding, functional activation, or an in vivo outcome? boundary

Valvular and handling risk

FDA records associate pergolide mesylate with heart-valve damage and document the 2007 US market withdrawal announcement; occupational classifications require separate evidence. [Federal Register](https://public-inspection.federalregister.gov/2014-15371.pdf?1404218983=)

1. What population, exposure, and evidence support each reported pergolide adverse effect, including valvular risk? provenance
2. Which current safety data sheet and applicable exposure controls cover the exact material being handled? action

Species-specific status

Store authorizations and withdrawals as scoped records; the FDA's 2011 PRASCEND approval summary provides an equine product reference. [FDA](https://animaldrugsatfda.fda.gov/adafda/app/search/public/document/downloadFoi/890)

1. Which current authority record governs the proposed pergolide product, species, indication, and jurisdiction? provenance
2. Is the cited record a historical approval, withdrawal, current authorization, or another regulatory decision? definition

Decision prerequisites

A proposed use requires matching material qualification, product context, and applicable restrictions.

1. Does the proposed action concern research material, pharmaceutical manufacture, or administration of a specific medicine? boundary
2. Which unresolved qualification, species restriction, or authorization condition prevents the action from proceeding? action
