Generic Tiazac products are sold under the name Diltiazem extended-release capsules and Taztia XT capsules. Various manufacturers (including Ethex Corporation and Watson Pharmaceuticals) make these generic products. The FDA has assigned all generic Tiazac products with an "AB" rating, meaning that the generic versions should be equivalent to the brand-name medication. However, generic medicines can have different inactive ingredients (such as fillers or dyes).
