What it is Filled

Cefsulodin is a semisynthetic third-generation cephalosporin antibiotic with a relatively narrow antibacterial spectrum, notably including Pseudomonas aeruginosa, that inhibits bacterial cell-wall synthesis.

In scope

  • Cefsulodin molecular identity, stereochemistry and source-qualified identifiers
  • Parent-substance, salt and hydrate distinctions relevant to supplied materials
  • Batch composition, purity, water content and antibacterial potency
  • Physical state, dissolution conditions and chemical stability
  • Condition-specific antibacterial evidence and material-use restrictions

Out of scope

  • Finished medicinal products, their excipients and packaging systems
  • Patient diagnosis, prescribing, dosing and treatment decisions
  • Manufacturing routes and production equipment
  • Complete bacterial organism and resistance-system models
  • Complete culture-medium formulations and microbiological procedures

Why it exists Filled

Enable an agent to recognise cefsulodin, assess the identity and condition of a particular material, and determine whether evidence supports its intended use.

Distinguishing features Filled

  • Require a structure match to cefsulodin, including its pyridinium-substituted cephalosporin identity; membership in the cephalosporin class alone is insufficient. [PubChem](https://pubchem.ncbi.nlm.nih.gov/compound/Cefsulodin)
  • Check counterions and hydration explicitly: PubChem records cefsulodin sodium separately from cefsulodin. [PubChem: cefsulodin sodium](https://pubchem.ncbi.nlm.nih.gov/compound/656644)
  • Compare stereochemical specification as well as connectivity before accepting a synonym or supplier identifier as an exact identity match.
  • Distinguish a cefsulodin material from a formulated preparation by identifying other constituents and the basis on which cefsulodin content is reported.
  • Use analytical identity evidence to distinguish cefsulodin from other antibiotics; a similar antibacterial response does not establish chemical identity.

What robots and AI may and may not do Filled

Must not

  • Recommend it or a dose for a person.
  • Supply it outside the regulated medicines chain.
  • Encourage antibiotic use that is not needed, which fuels resistance.

Only with a human decision

  • Any decision to treat an infection with it.

May

  • Describe cefsulodin, its antibacterial spectrum and its laboratory use in selective media.
  • Report its authorization status, which differs between countries.

Moral aspects Filled

  • Misuse of antibiotics breeds resistance that harms everyone.
  • People with penicillin or cephalosporin allergy face serious reactions.

Who is affected

  • Patients
  • The public at risk of resistant infection

Owners Filled

Steward

The marketing authorization holder or supplier; regulators and prescribers control its use.

Master systems

  • Medicines regulators' product registers

Links to other meta-models Filled

  • Q120892315 - registry parent class

Hazards and failure modes required Filled

  • Allergic reactions, including anaphylaxis, in sensitive people.
  • Misuse contributes to antibiotic resistance.

Standards and interfaces required Filled

  • The Anatomical Therapeutic Chemical classification, maintained by the World Health Organization Collaborating Centre for Drug Statistics Methodology, classifies cefsulodin among third-generation cephalosporins.
