Description
This medication concept set includes the following ingredients: Chlorothiazide, Chlorthalidone, Hydrochlorothiazide, Indapamide, and Metolazone. It also includes combinations of these ingredients with other antihypertensive medications. This code list was generated by taking the descendants of all the thiazide diuretic ingredients of interest, and also doing string matching on the concept_name of the ingredient. This broad concept set was intended to identify patients who received thiazide diuretics. Limited to NDC, RxNorm and RxNorm Extension codes. Meds were expected to be only oral/enteral/IV, not topical or buccal.
Technical 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, which would also make this easier to refresh.
