0INGRingredientRelates a component (player) to a mixture (scoper). E.g., Glucose and Water are ingredients of D5W, latex may be an ingredient in a tracheal tube.
1  ACTIactive ingredient**Definition:** a therapeutically active ingredient (player) in a mixture (scoper), where the mixture is typically a manufactured pharmaceutical. It is unknown if the quantity of such an ingredient is expressed precisely in terms of the playing ingredient substance, or, if it is specified in terms of a closely related substance (active moiety or reference substance).
2    ACTIBactive ingredient - basis of strength**Description:** Active ingredient, where the ingredient substance (player) is itself the "basis of strength", i.e., where the Role.quantity specifies exactly the quantity of the player substance in the medicine formulation. **Examples:** Lopressor 50 mg actually contains 50 mg of metoprolol succinate, even though the active moiety is metoprolol, but also: Tenormin 50 mg contain 50 mg of atenolol, as free base, i.e., where the active ingredient atenolol is also the active moiety.
2    ACTIMactive ingredient - moiety is basis of strength**Description:** Active ingredient, where not the ingredient substance (player), but itaTMs active moiety is the "basis of strength", i.e., where the Role.quantity specifies the quantity of the player substance's active moiety in the medicine formulation. **Examples:** 1 mL of Betopic 5mg/mL eye drops contains 5.6 mg betaxolol hydrochloride equivalent to betaxolol base 5 mg.
2    ACTIRactive ingredient - reference substance is basis of strength**Description:** Active ingredient, where not the ingredient substance (player) but another reference substance with the same active moiety, is the "basis of strength", i.e., where the Role.quantity specifies the quantity of a reference substance, similar but different from the player substance's in the medicine formulation. **Examples:** Toprol-XL 50 mg contains 47.5 mg of metoprolol succinate equivalent to 50 mg of metoprolol tartrate.
1  ADJVadjuvantA component (player) added to enhance the action of an active ingredient (scoper) (in the manner of a catalyst) but which has no active effect in and of itself. Such ingredients are significant in defining equivalence of products in a way that inactive ingredients are not.
1  ADTVadditiveAn ingredient (player) that is added to a base (scoper), that amounts to a minor part of the overall mixture.
1  BASEbaseA base ingredient (player) is what comprises the major part of a mixture (scoper). E.g., Water in most i.v. solutions, or Vaseline in salves. Among all ingredients of a material, there should be only one base. A base substance can, in turn, be a mixture.
1  CNTMcontaminant ingredientAn ingredient whose presence is not intended but may not be reasonably avoided given the circumstances of the mixture's nature or origin.
1  IACTinactive ingredientAn ingredient which is not considered therapeutically active, e.g., colors, flavors, stabilizers, or preservatives, fillers, or structural components added to an active ingredient in order to facilitate administration of the active ingredient but without being considered therapeutically active. An inactive ingredient need not be biologically inert, e.g., might be active as an allergen or might have a pleasant taste, but is not an essential constituent delivering the therapeutic effect.
2    COLRcolor additiveA substance (player) influencing the optical aspect of material (scoper).
2    FLVRflavor additiveA substance (player) added to a mixture (scoper) to make it taste a certain way. In food the use is obvious, in pharmaceuticals flavors can hide disgusting taste of the active ingredient (important in pediatric treatments).
2    PRSVpreservativeA substance (player) added to a mixture (scoper) to prevent microorganisms (fungi, bacteria) to spoil the mixture.
2    STBLstabilizerA stabilizer (player) added to a mixture (scoper) in order to prevent the molecular disintegration of the main substance.
1  MECHmechanical ingredientAn ingredient (player) of a medication (scoper) that is inseparable from the active ingredients, but has no intended chemical or pharmaceutical effect itself, but which may have some systemic effect on the patient. An example is a collagen matrix used as a base for transplanting skin cells. The collagen matrix can be left permanently in the graft site. Because it is of bovine origin, the patient may exhibit allergies or may have cultural objections to its use.

Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
