    Formulations with diltiazem is really confusing to me and I was hoping someone could clarify there is the IR, 12hr formulation, 24 forumlation, beads, CD, LX, Tazatia.... Also, what do you think when there was a script written for diltizem er 12 hr capsules taken tid, is that something that is pretty common? Why can't they just do regular diltizem if they wanted to take it tid.

    Stop looking for it to make sense. It doesn't.

    Look back and see what the patient was taking before in their profile and if it's different then I would contact prescriber. Also interaction with simvastatin gets flagged

    You can use the link below. Click on a drug in question then select the Therapeutic Equivalents link and this will tell you the forms "appropriate" to substitute. If your state doesn't stipulate AB substitution consider it a resource for clarification of generics for Cardizem CD vs Dilacor XR. Also note marketing status as many are discontinued. I pasted an example showing what TAZTIA XT is considered interchangeable with per FDA standard.
