Does acarbose belong to with drug class?

Acarbose belongs to a family of medications known as alpha-glucosidase inhibitors. It works by slowing down the action of enzymes that break down meals into glucose.

Why is acarbose used for hypoglycemia?

Acarbose inhibits an enzyme that converts glucose from starchy carbs (like bread, potatoes, etc.) in the colon. As a result, your body will absorb less glucose from food, giving your pancreas more time to produce more insulin and decrease blood sugar levels after meals.

Does acarbose prevent diabetes?

It has been demonstrated to reduce the incidence of type 2 diabetes and hypertension in people with impaired glucose tolerance (IGT). The only oral diabetic medication that is presently licensed for the treatment of both prediabetes and type 2 diabetes is acarbose.
