Once inside the presynaptic terminal, amphetamine increases the amounts of monoamine neurotransmitters hinein the cytosol through the inhibition of vesicular monoamine transporter 2 (VMAT2) as well as through disruption of the electrochemical gradients necessary for vesicular transporter function.

A comparison of the mean peak increases hinein systolic and diastolic blood pressure produced by intravenous versus oral administration of 50 mg lisdexamfetamine.
Immediate-release formulations may be preferred initially to establish an optimal daily dose, with conversion to an extended-release formulation thereafter. Extended-release formulations are intended for once-daily dosing, but they may require concomitant use of an immediate-release medication as the clinical effect wears off hinein the afternoon.[6] Patients with narcolepsy generally benefit from divided doses and may require an early afternoon dose to control daytime sleepiness.
Due to their ability to produce powerful euphoric effects, amphetamines are common drugs of abuse. All major drugs of abuse increase dopamine concentrations hinein the mesolimbic pathway, but amphetamines, because of their direct effects on DAT and VMAT2, can increase dopamine concentrations far beyond the concentrations seen for natural rewarding stimuli.
Furthermore, switching to the intravenous route for lisdexamfetamine appeared to have relatively little influence on the abuse potential of the prodrug.
