Groupers Based on Disposition
Overview
A high-level grouper concept supports the organization of the medicinal product concepts based on disposition: 766779001 |Medicinal product categorized by disposition (product)|
Disposition is a behaviour that something can exhibit (or participate in) given the appropriate context in which to do this. For example, a person may be "disposed" (or pre-disposed) to fidget in their seat when in a stressful situation such as an interview. For medicinal products, disposition behaviour can be thought of as "mechanism of action" of its active ingredient substance(s): the behaviour that the active ingredient substance(s) in the product exhibit when used clinically. Disposition (mechanism of action) is distinguishable from therapeutic role, which is context dependent: for example the mechanism of action of timolol is as a beta-adrenoceptor antagonist; this action can be used therapeutically to reduce hypertension when administered in a product given orally or to treat glaucoma when administered in a product intended to be given ophthalmically. Medicinal products can be collected together into groups based on the disposition of their active ingredient substance(s).
Disposition is a characteristic of the active ingredient substance(s) present in the Medicinal Product, therefore disposition grouping concepts are assigned (inferred) by the classifier to medicinal products and to all their child concepts (medicinal product form and clinical drug concepts) although in a browser such as DailyBuild the inferred grouping concepts will be shown on the proximal concept only (the "medicinal product containing" concept).

This section applies to grouper concepts representing a single disposition; groupers comprised of multiple dispositions are described in Groupers Based on Multiple Dispositions, Structures.
