The antidiabetic drug glibenclamide exerts direct retinal neuroprotection.
Abstract Sulfonylureas, widely used as hypoglycaemic agents in adults with type 2 diabetes, have neuroprotective effects in preclinical models of central nervous system injury, and in children with neuropsychomotor impairments linked to neonatal diabetes secondary to ATP-sensitive potassium channel mutations. In the human and rodent retina, we show that the glibenclamide activated channel SUR1 is expressed in the retina and enriched in the macula; we also show that it co-localizes with the potassium channel Kir6.2, and with the cation channel transporter TRPM4. Glibenclamide (glyburide), administered at doses that...
