DrugStrength

DrugStrength is a MedicalIntangible for the strength in which a drug is available in a specific country. A single drug usually has several DrugStrength entries (5 mg, 10 mg, 20 mg tablets), each with its own regulatory approval.

Direct properties:

activeIngredient (Text): chemical / biologic active substance.
strengthValue (Number): numeric strength.
strengthUnit (Text): unit (mg, mg/ml, IU).
maximumIntake (MaximumDoseSchedule): the recommended population-level intake ceiling.
availableIn (AdministrativeArea): where the strength is marketed.

Common DrugStrength mistakes

Mistakes that pass validation but silently fail to earn rich results or mislead consumers walking the graph. Avoid these and your markup will be ahead of most sites in the wild.

01
Strength concatenated in name only
Wrong
```
Drug.name = "XooStat-12 10 mg" with no DrugStrength
```
Right
```
Separate DrugStrength entity with strengthValue + strengthUnit
```
Prescribing systems parse strengthValue and strengthUnit; embedded-in-name strength is invisible to them.
