title: Effect of ascorbic acid on brain amphetamine concentrations in the rat.
abstract: Ascorbic acid is reported to have antiamphetamine effects in rodents. The effect of ascorbic acid (1 g/kg ip) on the half-life of amphetamine (10 mg/kg) in rat brain using 3H-amphetamine and on amphetamine-induced stereotyped behaviour was investigated. Ascorbic acid had no effect on amphetamine-induced stereotyped behaviour or on the half-life of amphetamine in brain. If ascorbic acid antagonizes amphetamine-induced behavioural responses this is unlikely to be a result of altering the pharmacokinetics of amphetamine.
