Glucobay 25 Tablet contains Acarbose 25 mg, an oral antidiabetic agent used primarily for the management of type 2 diabetes mellitus. Acarbose acts as an alpha-glucosidase inhibitor, delaying the digestion and absorption of carbohydrates in the small intestine, thereby reducing postprandial hyperglycemia. It is indicated as an adjunct to diet and exercise to improve glycemic control in patients with type 2 diabetes, particularly when diet alone or in combination with other antidiabetic agents does not achieve adequate control. Glucobay 25 is administered orally, typically at the start of each main meal, with dosage individualized based on patient response and tolerability. Common side effects include gastrointestinal disturbances such as flatulence, diarrhea, and abdominal discomfort, which often diminish with continued use. It is contraindicated in patients with diabetic ketoacidosis, inflammatory bowel disease, or conditions associated with malabsorption. Regular monitoring of blood glucose levels is essential to assess therapeutic efficacy. Glucobay 25 should be used cautiously in patients with hepatic impairment and is not recommended during pregnancy or lactation unless clearly necessary. Patient education on adherence to dietary recommendations and recognition of hypoglycemia symptoms is crucial to optimize treatment outcomes.
