Sulfonylureas refer to a group of medications that are commonly used to treat type 2 diabetes. Some of the synonyms for sulfonylurea include oral hypoglycemic agents, anti-diabetic drugs, and sulfonylurea derivatives. These medications work by increasing the amount of insulin produced by the pancreas and helping the body to better utilize glucose in the blood. Some commonly prescribed sulfonylureas include glyburide, glipizide, and tolbutamide. While these medications can be very effective in controlling blood sugar levels in people with type 2 diabetes, they can also have side effects such as low blood sugar levels and weight gain. It is important to work closely with a healthcare provider to ensure the safe and effective use of these medications.
