How Epalrestat works
Epalrestat is a reversible aldose reductase inhibitor.
It works by blocking the enzyme aldose reductase, which usually converts glucose to sorbitol. In people with diabetes, high blood sugar levels cause this enzyme to become overactive, leading to excess sorbitol buildup in nerves, which can damage them. By inhibiting aldose reductase, Epalrestat helps reduce sorbitol accumulation and protects nerve function.
