What it is Filled
Flunisolide is a synthetic fluorinated glucocorticoid used as a locally administered anti-inflammatory drug in inhaled preparations for asthma maintenance and intranasal preparations for allergic rhinitis.
In scope
- Molecular structure, stereochemistry and verified substance identifiers
- Anhydrous, hydrated or solvated material descriptions within the registry entry
- Lot composition, assay basis, impurities and pharmaceutical or research grade
- Physical properties, dissolution behaviour and storage-dependent condition
- Evidence linking substance quality and hazards to an intended use
Out of scope
- Finished nasal solutions and inhalation products, including excipients and labelled strength
- Spray pumps, inhalers and delivered-dose performance
- Patient diagnosis, prescribing and individual treatment decisions
- Manufacturing processes and production equipment
- Other corticosteroids and flunisolide metabolites as independent substances
Why it exists Filled
Enable an agent to recognise flunisolide, assess the identity and condition of a material lot, and determine its suitability for a specified research or pharmaceutical use.
Distinguishing features Filled
- Require agreement with the reference flunisolide stereostructure, including its 6α-fluoro substitution and cyclic 16,17-acetal with acetone; a corticosteroid class label alone is insufficient.
- Use C24H31FO6 and approximately 434.51 g/mol as consistency checks for the unsolvated molecule, while requiring structural evidence to distinguish isomers. [DailyMed substance description](https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=f39cae46-c68f-47ef-82f3-4fd3dd46c74c)
- Distinguish neat flunisolide from a solution containing flunisolide by recording the full composition and the denominator used for concentration.
- Distinguish water or solvent associated with the material from the parent molecular identity before interpreting molecular mass, assay or weighed quantity.
- Match identifiers to a stereochemically specified substance record rather than accepting a similarly named supplier or product record; PubChem lists flunisolide as CID 82153. [PubChem flunisolide](https://pubchem.ncbi.nlm.nih.gov/compound/Flunisolide)
What robots and AI may and may not do Filled
Must not
- Recommend it or a dose for a particular person's asthma or rhinitis.
- Present a maintenance inhaler as a rescue treatment for an asthma attack.
- Supply it outside lawful pharmaceutical channels.
Only with a human decision

- Releasing or destroying a material lot.
May
- Identify flunisolide by name, identifiers and documented properties, citing sources.
- Report approved inhaled and nasal uses from official product information.
- Check a material lot's certificate of analysis against its specification.
Moral aspects Filled
- Asthma attacks can kill; confusion between maintenance and rescue treatment is dangerous.
- Steroid use in children raises concerns that need honest information.
Who is affected
- People with asthma or rhinitis
- Children and parents
- Prescribers and pharmacists
