Simeglutide Injection mainly has the effect of stimulating insulin secretion and lowering blood glucose concentration. Simeglutide Injection is a long-acting glucagon-like peptide-1 analog that can stimulate insulin secretion, reduce glucagon levels and thus lower blood glucose concentration. It is indicated for adults with type 2 diabetes mellitus, especially those with cardiovascular disease or poor glycemic control on metformin or sulfonylureas. It is contraindicated in patients with hypersensitivity to the product or with a personal or family history of medullary thyroid carcinoma. Although Simeglutide Injection has more effects, some patients experience adverse reactions such as nausea, diarrhea, vomiting, and hypoglycemia after use. Therefore, it is recommended to use the drug under the guidance of a doctor, not blindly self-medication to avoid adverse effects.
