Overview
CD-precise concepts representing continuous dose form (e.g., solutions, suspensions, creams, ointments, patches) are modeled using concentration strength attributes; presentation strength attributes are not allowed for these concepts in the International Release.
For example,
- Product containing precisely zidovudine 10 milligram/1 milliliter conventional release oral solution (clinical drug)
- Product containing precisely amikacin (as amikacin sulfate) 250 milligram/1 milliliter conventional release solution for injection (clinical drug)
- Product containing precisely clotrimazole 10 milligram/1 gram conventional release cutaneous cream (clinical drug)
- Product containing precisely mupirocin (as mupirocin calcium) 20 milligram/1 gram conventional release nasal ointment (clinical drug)
- Product containing precisely buprenorphine 70 microgram/1 hour prolonged-release transdermal patch (clinical drug)
For solids and semi-solids, a concentration strength will be mass/mass (w/w) – usually mg/g.*
For liquids, a concentration strength will be mass/volume (w/v) – usually mg/mL.*
*Requests for new concepts that conflict with the above require a clear justification for the variance.

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

Synonyms | Synonyms converting metric units to percent or parts per millions may be included for medical gas concepts (e.g. Helium 79% and oxygen 21% gas for inhalation, Helium 790,000 ppm and oxygen 210,000 ppm gas for inhalation). |
