This document discusses treatment options after metformin for type 2 diabetes, comparing sulfonylureas and gliptins. It provides the following key points:
1. Sulfonylureas are more effective at reducing HbA1c levels and achieving glycemic control targets compared to gliptins. They lower HbA1c by 1-2% on average versus 0.5-1% for gliptins.
2. Studies show sulfonylureas may better preserve beta-cell function in the long-term compared to metformin or gliptins. They have been shown to enhance insulin secretion from beta and alpha cells.
3. While older studies linked sulfonylureas
