“5 of …, D-amphetamine … pM , (+)methamphetamine at 114 pM, but methylphenidate only at 291 pM. This interaction was stereospecific as evidenced by the higher relative K0.s … DLamphetamine (75 pM) and (+/-)methamphetamine (179) pM. These compounds also inhibit the initial rate of serotonin transport by platelet plasma membrane vesicles.”
“ D-Amphetamine and (+)methamphetamine also inhibited transport with K0.s values of 7.4 and 8.7 pM , respectively.”
