    Scientific background

    Glibenclamide is a member of the sulfonylurea class of drugs, an anti-diabetic that inhibits KATP channels in pancreatic β-cells, leading to increased insulin release. Sulfonylurea drugs work by inhibiting sulfonylurea receptor 1 (SUR1). In addition, this drug acts as aTRPA1 agonist and demonstrates pleiotropic protective effects in acute CNS injury. Glibenclamide activates human TRPA1 in a concentration range that is commonly used to inhibit KATP channels in vitro. It has an EC50 value isof 48 nM at pH 7.45.

    Glibenclamide exhibits adverse effects such as abdominal pain, gastrointestinal disturbances and nocturia1,2. It is a weak acid, lipid soluble, with an oral clearance ranging from 11.2 to 230 l/h, with an elimination half-life estimated at about 4 h3.

    Promising preclinical results suggest that glibenclamide significantly reduces cerebral edema and lowers the rate of hemorrhagic conversion following ischemic stroke. In non-lethal models, glibenclamide reduces brain swelling and infarct volume and improves neurological function. In lethal models of malignant cerebral edema, glibenclamide reduces edema, brain swelling, and mortality3,4.
