“The current study assessed whether l-deprenyl or its isomer would maintain drug-seeking behavior on a second-order schedule and whether l-deprenyl would alter drug-seeking behavior maintained by d-amphetamine if given as a pretreatment.”
“Under conditions where drug-seeking and drug-taking behaviors are actively maintained by d-amphetamine, l-deprenyl , at doses that specifically inhibit type B monoamine oxidase, may not be effective as a treatment.”
