[2025-10-01T16:49:09.286946] [PI reasoning] **Evaluating DPP-4 inhibitors for renal failure**

I'm focusing on which DPP-4 inhibitors are safe for individuals with renal failure. Sitagliptin and saxagliptin both require dose adjustments due to renal excretion. Vildagliptin also needs adjustment for moderate or severe impairment, while linagliptin doesn’t need any adjustments since it's mostly excreted through the bile. So, I'll highlight linagliptin as my answer. I need to find some articles to support this claim about linagliptin's renal safety. Let’s look for evidence!
