Key takeaways
Nateglinide (formerly Starlix) and glyburide (Glynase) are both oral medications used to manage Type 2 diabetes, but they belong to different classes and have distinct characteristics. Nateglinide needs to be taken three times a day before meals and works by quickly stimulating the pancreas to release insulin, helping to control blood sugar levels after meals. Glyburide, on the other hand, is typically taken once or twice daily with the first main meal. Like nateglinide, it also stimulates the release of insulin in the pancreas but does it in a different way. Glyburide can lower A1C levels by 1.5%, which is higher than the 0.75% reduction seen with nateglinide. Both medications can cause low blood sugar, but glyburide has a higher risk, especially in older adults or those with kidney or liver issues. On the other hand, nateglinide is more likely than glyburide of causing weight gain. Additionally, glyburide has a potential risk of heart problems and hemolytic anemia.
