Could an allergy drug shield diabetics from organ damage?

NCT ID NCT07685886

First seen Jul 06, 2026 · Last updated Jul 07, 2026 · Updated 1 time

Summary

This study tests whether montelukast, a common allergy medication, can reduce damage to the kidneys, eyes, and blood vessels in adults with type 2 diabetes and early kidney disease. The drug works by blocking inflammatory chemicals called leukotrienes, which are linked to diabetes complications. Participants take either montelukast or a placebo daily for 12 months while researchers measure changes in kidney function, blood vessel health, and eye health.
