[southalln]

FDA's SPL contains information on the intended use of products that corresponds nicely to Treament Modality in Inxight.

I forget how this information comes from FRDB - but one might be able to supplement it with FDA SPL data.

Primary Substance halts or slows disease progression. Treatment often targets the primary pathology of a disease. Preventing Substance is intended to prevent the development of a medical condition. Palliative Substance improves the quality of life by alleviating the associated symptoms, without necessarily affecting the underlying pathology. Secondary Substance treats adverse effects associated with the treatment of a condition. Diagnostic A substance used for diagnostic purposes, including disease detection and monitoring of disease progression. Inactive Ingredient An ingredient of a given formulation (most frequently, an excipient) that does not exhibit pharmacological activity. In this case, a condition is only related to such compound via the formulation used to affect (treat or diagnose) this condition.
