Stated parent concept

763158003 |Medicinal product (product)

Semantic tag(clinical drug)
Definition status

900000000000073002 |Sufficiently defined by necessary conditions definition status (core metadata concept)|

  • Exceptions:
    • Concepts with product strength that is "not equal to" (e.g. with product strength expressed as a range, greater than, or less than) will have definition status 900000000000074008 |Necessary but not sufficient concept definition status (core metadata concept)|.

Attribute:

Has manufactured dose form

Range: 736542009 |Pharmaceutical dose form (dose form) - descendants only

      • NOTE: While the allowed range for this attribute is broader, the CD-precise discrete dose form concepts should only use descendants of 736542009 |Pharmaceutical dose form (dose form), excluding grouper concepts based on intended site (e.g. 740596000 |Cutaneous dose form (dose form)|, 385268001 |Oral dose form (dose form)|)

Cardinality: 1..1

The attribute value should represent the manufactured dose form.

Notes:

  • Concepts with dose form of drops or spray will be modeled in the International Release with Pharmaceutical dose form concepts that do not specify the basic dose form (e.g. 385018001 |Conventional release oral drops (dose form)| or 385073003 |Conventional release oromucosal spray (dose form)|).
      • More specific Pharmaceutical dose form concepts (e.g. 385019009 |Conventional release solution for oral drops (dose form)| or 761905004 |Conventional release solution for oromucosal spray (dose form)|) will be retained in the International Release but will not be used for modeling Clinical drug concepts; they can be used for modeling in national extensions.
  • Powder and granules for oral suspension, solution, etc. may be modeled using concentration strength and the administrable dose form (e.g. 1145409004 |Product containing precisely amoxicillin 25 milligram/1 milliliter and clavulanic acid (as clavulanate potassium) 6.25 milligram/1 milliliter conventional release oral suspension (clinical drug)|)
  • Clinical drug concepts in the International Release should not be modeled using dose forms for “lyophilized powder” because it is not a clinically relevant distinction at the Clinical drug level.
    • Pharmaceutical dose forms referring to “lyophilized powder” will be retained in the International Release but will not be used for modeling Clinical drug concepts; they can be used for modeling in national extensions.

Attribute:

Has unit of presentation

Range: 732935002 |Unit of presentation (unit of presentation)| - descendants only

Cardinality: 1..1

Attribute:

Count of base of active ingredient (attribute)

Concrete Type: Integer

Range: >#0..

Cardinality: 1..1

Relationship groupOne relationship group containing one instance of each of the following attributes is required for each precise active ingredient.
  • Has precise active ingredient

Range: 105590001 |Substance (substance)| - descendants only, excluding concepts representing structural groupers, dispositions, or combined substances

Cardinality: 1..1 per relationship group

Notes:

  • The PAI cannot be modeled as a substance hydrate or solvate unless the BoSS is expressed as a hydrate or solvate.
  • Concepts containing pancreatic enzymes will be modeled based on the discrete enzymes; because of variability between real clinical drugs, synonyms representing a total amount in a particular product will not be included in the International Release.
  • Has basis of strength substance
  • Range: 105590001 |Substance (substance)| - descendants only, excluding concepts representing structural groupers, dispositions, or combined substances
  • Cardinality: 1..1 per relationship group
  • Has presentation strength numerator value 

Concrete Type: Decimal

Range: >#0..

Cardinality: 1..1 per relationship group

Expression of product strength in metric units is preferred.

To avoid semantically equivalent concepts, product strength for metric units are normalized as follows:

  • Use milligram if value is <1000; if > then convert to gram
  • Use microgram if value is <1000; if > then convert to milligram
  • Use nanogram if value is <1000; if > then convert to microgram
  • Use picogram if value is <1000; if > then convert to nanogram

To avoid semantically equivalent concepts, product strength for units are normalized as follows:

  • Use million unit if value is >1000000 unit

The following units are not allowed unless specifically noted as an exception:

  • 408165007 |Mega u (qualifier value)|

Repeating decimals are rounded to three decimal places (with 5 and above rounded up and 4 and below rounded down).

  • Has presentation strength numerator unit

Range: 767524001 |Unit of measure (qualifier value)| - descendants only

Cardinality: 1..1 per relationship group

  • Has presentation strength denominator value

Concrete Type: Decimal

Range: >#0..

Cardinality: 1..1 per relationship group

For this pattern the attribute value must be 38112003 |1 (qualifier value)|

Note: the denominator strength value is required for concepts in the International Release even if the value = 1 because including denominators for only some concepts negatively affects the classification results.

  • Has presentation strength denominator unit
  • Range: 767524001 |Unit of measure (qualifier value)| - descendants only
    • While the allowed range for this attribute is broader, the CD-precise concepts representing discrete dose forms should only use descendants of 732935002 |Unit of presentation (unit of presentation).
  • Cardinality: 1..1 per relationship group
