Aldose reductase inhibitors in clinical practice. Preliminary studies on diabetic neuropathy and retinopathy.

Abstract

Extensive animal data now exist to indicate potential benefit of sorbinil in the treatment of the major complications of diabetes mellitus. A clinical programme has been constructed to explore this therapeutic potential and encouraging evidence of drug effect has already been observed in patients with neuropathy and retinopathy. Two small preliminary studies in patients with painful neuropathy have shown that clinically significant reduction of pain was more frequently achieved with sorbinil than with placebo. A 6-month study of patients with retinopathy, using vitreous fluorophotometry as the criterion of retinal damage, showed significant (p = 0.03) benefit for the sorbinil group compared with the placebo group. Drug evaluation in these areas is complex and difficult but it is anticipated that the accumulation of additional data will further substantiate the efficacy suggested by these early findings. The only clinically important adverse effect of sorbinil is the hypersensitivity reaction. This usually occurs during the initial weeks of therapy and is similar to that seen with phenytoin. The long term use of sorbinil is without significant adverse effects.
