TOLRESTAT

Description

Tolrestat is a long-acting aldose reductase inhibitor reportedly useful in the prophylaxis of diabetic neuropathy, retinopathy and cataracts.

Description

Tolrestat is an aldose reductase inhibitor (IC₅₀ = 35 nM for the bovine lens enzyme). Dietary administration of tolrestat decreases sciatic nerve galactitol accumulation in a rat model of galactosemia (ED₅₀ = 7.3 mg/kg per day) and sciatic nerve sorbitol accumulation (ED₅₀ = 4.8 mg/kg per day) in a rat model of diabetes induced by streptozotocin (STZ; ). It also decreases urinary total protein exretion in a rat model of STZ-induced diabetes when administered at a dose of 25 mg/kg per day. Topical administration of tolrestat (2 and 3% in 10 μl four times per day) decreases levels of galactitol in the lens of and inhibits cataract formation in rats fed a high-galactose diet.
