title: Lignocaine disposition in blood in epilepsy.
abstract: 1 The plasma concentration of alpha 1-acid glycoprotein (AAG) was significantly greater in 27 epileptic subjects receiving anticonvulsants compared with 27 age- and sex-matched drug-free control subjects. 2 Increased AAG concentration was associated with enhanced lignocaine binding in the plasma of epileptics. 3 Increased AAG concentration was also associated with a redistribution of lignocaine out of red cells and into plasma thus lowering the blood to plasma concentration ratio. 4 Enhanced lignocaine binding in epileptics receiving anticonvulsant therapy may result in lower free (unbound) plasma concentrations of the drug compared to normal subjects with equivalent total plasma lignocaine concentrations.
