Drugs that also have the same effect as acarbose include voglibose and miglitol. Acarbose, voglibose, and miglitol are all alpha glucosidase inhibitors, and their main effect is to lower postprandial blood glucose. the mechanism of action of alpha glucosidase inhibitors is to inhibit the enzyme alpha glucosidase in the intestinal mucosa, thus delaying the breakdown of starch into glucose in the food, and decreasing or preventing the absorption of glucose in the small intestine, which can help to lower postprandial blood glucose. Common adverse reactions to this drug are gastrointestinal reactions such as bloating, increased gas or diarrhea. Starting with a small dose and gradually increasing the dosage is an effective way to minimize adverse reactions. Note that the drug should not be used in patients with gastrointestinal disorders, pregnant women, lactating women and children. Patients should use the drug under the supervision of a medical professional.
