Acarbose tablets and metformin extended-release tablets can be taken at the same time under the guidance of a doctor, their mechanism of action is different, generally no interaction, for the commonly used glucose-lowering joint program. Acarbose tablets: inhibit α-glucosidase in the small intestine, inhibit the decomposition of polysaccharides in food, slow down the absorption of sugar accordingly, so as to reduce the postprandial hyperglycemia, and cooperate with the dietary treatment of diabetes mellitus. It needs to be swallowed whole or chewed with the first few bites of food immediately before a meal. Metformin extended-release tablets: Metformin is an oral hypoglycemic drug. It has several mechanisms of action, including delaying the uptake of glucose from the gastrointestinal tract, increasing peripheral glucose utilization by improving insulin sensitivity, and inhibiting excessive hepatic glycogen isomerization, and should be taken with food. The combination of the two can control both fasting and postprandial blood glucose, reduce blood glucose fluctuations, and facilitate the control of blood glucose levels. If you suffer from diabetes, do not take medication on your own, but go to the hospital in time and take medication under your physician’s guidance, taking into account your individual situation.
