You could also train a custom parser like in this [example](https://spacy.io/usage/examples#intent-parser). So you keep `DRUG` as an entity but `DOSAGE` is a relation to that entity. This [example](https://spacy.io/usage/examples#entity-relations) might inspire you as well.

If you find those approaches relevant then I suggest you follow this [thread](https://support.prodi.gy/t/annotation-scheme-workflow-for-entity-relations/3547) that I just started on the subject.
