Acarbose tablets are an oral medication used to manage type 2 diabetes by lowering blood sugar levels after meals. Acarbose works by inhibiting enzymes in the small intestine that break down complex carbohydrates into simple sugars, which slows glucose absorption. By delaying carbohydrate digestion, acarbose helps prevent spikes in blood glucose levels following meals. It is most effective when taken with the first bite of each main meal and is typically used alongside diet and exercise or in combination with other diabetes medications.
