Mode Of Action:

Alpha-glucosidase inhibitors slow down the digestion and absorption of carbohydrates by blocking the enzyme alpha-glucosidase, which helps in digesting carbohydrates in the small intestine. This slowing down of absorption causes the blood sugar level to peak less after a carbohydrate-rich meal and therefore aids in a better blood sugar control.

Both Voglibose and acarbose, associated with an increase in the glucagon-like peptide (GLP-1), which has an insulinotropic effect and which has an inhibitory effect on glucagon secretion, which results in overall reduction postprandial hyperglycemia. (source).
