The Effect of Aldose Reductase Inhibition on Motor Nerve Conduction Velocity in Diabetic Rats

This study examined the effects of an aldose reductase inhibitor (CP 45634, Sorbinil, Pfizer, New York, New York) on the neuropathy of streptozotocin-induced diabetic rats. Sorbinil treatment for 4 wk reduced sciatic nerve sorbitol concentration and improved motor nerve conduction velocity in diabetes of 2–9 mo duration. It remains to be determined whether Sorbinil can prevent chronic diabetic neuropathy.
