Enantioselective determination of plasma protein binding of common amphetamine-type stimulants.
2021
Amphetamine-type stimulants (ATS) like amphetamine ('speed'), methamphetamine ('crystal meth') and 3,4-methylenedioxy-N-methylamphetamine (MDMA, 'ecstasy') represent some of the most frequently abused drugs worldwide. Another less frequently abused ATS is 4-fluoroamphetamine (4-FA). The enantiomers of these four compounds exhibit different pharmacokinetic and pharmacodynamic properties. According to the free drug theory, the pharmacological properties of a substance are dependent on its plasma protein binding (PPB). However, data on PPB of stimulant enantiomers in humans are rare or non-existent. Human plasma samples were spiked with racemic mixtures of the stimulants and subjected to ultra…
