He reports that he has been compliant with his current antidiabetic medication regimen. His hemoglobin A1c concentration is 8.5. The physician prescribes a drug that reversibly inhibits a membrane-bound enzyme that hydrolyzes carbohydrate bonds. Which of the following drugs was most likely added to this patients medication regimen?? A: Linagliptin, B: Canagliflozin, C: Pramlintide, D: Miglitol, E: Rosiglitazone,  <response>: This is a clinical vignette about a 56-year-old man with type 2 diabetes mellitus who has an elevated hemoglobin A1c level of 8.5 despite being compliant with his antidiabetic medications. The physician prescribes a new medication that inhibits an enzyme that breaks down carbohydrates. Based on the information provided, the new medication is likely a glucosidase inhibitor like acarbose or miglitol. These drugs work by inhibiting alpha-glucosidase enzymes in the brush border of the small intestine, which prevents the breakdown of complex carbohydrates into simple sugars and thereby reduces postprandial hyperglycemia. Of the answer choices provided, miglitol is a glucosidase inhibitor that fits with the mechanism of action described in the question stem. The other options are drugs with different mechanisms of action that do not match the description provided.D: Miglitol
