The generic name of Bayzapine is Acarbose. There are some differences between Gliclazide and Acarbose in terms of mechanism of action, indications, contraindications, and adverse reactions. 1. Mechanism of action: Acarbose is an α-glucosidase inhibitor, which can delay the degradation of oligosaccharides, disaccharides, and polysaccharides in the intestinal tract, slow down the degradation of glucose from carbohydrates and its absorption into the bloodstream, and ultimately lower blood sugar. Gliclazide is a sulfonylurea oral hypoglycemic drug, which can selectively act on pancreatic β-cells to promote insulin secretion, and then lower blood sugar. 2. Indications: Acarbose is mainly used for the treatment of patients with elevated blood glucose after meals. Gliclazide can reduce fasting and postprandial blood glucose. 3. Contraindications: Gliclazide should not be used in people who are allergic to this drug and other sulfonylureas, pregnant and lactating women, severe hepatic and renal insufficiency, etc.; Acarbose should not be used in patients who are allergic to this drug, severe renal impairment, diabetic ketoacidosis and so on. 4. Adverse reactions: taking gliclazide can appear hypoglycemia, abdominal pain, nausea, vomiting, rash, itching and other adverse reactions; taking acarbose may appear after abdominal distension, bowel sound hyperpnea, increased gas, allergies and other adverse reactions. Patients requiring treatment with gliclazide or acarbose should take the medication under the supervision of a doctor.
