title: Inhibition of gamma-aminobutyric acid uptake into astrocytes by pentobarbital.
abstract: Pentobarbital (0.5-2mM), but not phenobarbital, was found to inhibit the uptake of gamma-aminobutyric acid into mouse astrocytes in primary cultures up to 45%. This inhibition was additive to a reduction in uptake rate caused by excess potassium. Its possible role in the pharmacological action of pentobarbital is discussed.
