Abstract
Objective
Overexpression of the drug transporter P‐glycoprotein (P‐gp) is thought to be involved in drug‐resistance in epilepsy by extrusion of antiepileptic drugs (AEDs). We used positron emission tomography (PET) and the P‐gp substrate radiotracer (R)‐[11C]verapamil (VPM) together with the third‐generation P‐gp inhibitor tariquidar (TQD) to evaluate P‐gp function in individuals with drug‐resistant epileptogenic developmental lesions.
Methods
Twelve healthy controls (7 male, median age 45, range 35‐55 years), and two patients with epileptogenic developmental lesions (2 male, aged 24 and 62 years) underwent VPM‐PET scans before ...
