Acarbose is primarily used in the management of type 2 diabetes mellitus. It works by slowing down the digestion of carbohydrates in the intestine, which helps to control blood sugar levels after meals. This makes it particularly effective for individuals who experience significant postprandial glucose spikes. Acarbose is often prescribed alongside other diabetes medications or lifestyle changes, such as diet and exercise, to enhance glycemic control. It is taken orally with the first bite of each main meal. Additionally, it is sometimes used in the prevention of diabetes in individuals with prediabetes, as it can help delay the progression to full-blown diabetes. Due to its mechanism of action, it may cause gastrointestinal side effects like bloating, flatulence, or diarrhea, but these often diminish with continued use. Acarbose is not suitable for individuals with certain digestive disorders, such as inflammatory bowel disease or intestinal obstruction.
