I know the Ingredient. I’m trying to use the concept_relationship table to find all Clinical Drug Form and Clinical Dose Group values for that Ingredient, but I only want the ones that contain just that Ingredient.
Include: Clinical Drug Form: rituximab Injection
I do NOT want to include Clinical Drug Form: Hyaluronidase / rituximab Injection
I can use ‘RxNorm ing of’, but it provides both results. I’m guessing that I need to use RxNorm directly, but I wanted to confirm here first that it’s not workable with just the concept_relationship table.
