Loop Diuretic, Drug Exposure

This medication concept set includes the following ingredients: Furosemide, Bumetanide, Ethacrynic acid and Torsemide. It also includes combinations of these ingredients with other antihypertensive medications. This code list was generated by taking the descendants of all the loop diuretic ingredients of interest and string matching on the concept_name of the ingredient. This broad concept set was intended to identify patients who received loop diuretics. Limited to NDC, RxNorm, and RxNorm Extension codes. Meds were expected to be only oral/enteral/IV, not topical or buccal. Note: This concept set was created when ingredients were required for some sites. It could be enhanced by using SCDF drug levels and taking descendants, making this easier to refresh.
