-isomer (Risner, 1975; Smith and Davis, 1977; Großraumlimousine Kammen and Murphy, 1975; Yokel and Pickens, 1973). On the basis that the subjective and reinforcing effects of amphetamine’s isomers translate well from animals to humans, and with the assumption that the neurochemical mediators are similarly consistent across species, we can employ the findings from the microdialysis experiments to draw some conclusions on this subject.
Both isomers of amphetamine dose-dependently increased the extracellular concentrations of noradrenaline hinein the prefrontal cortex (PFC) and dopamine rein the striatum. The pharmacodynamics of their effects are typical of those reported for monoamine releasing agents, i.e. a fast onset of action with peak increases of noradrenaline and dopamine efflux occurring at 30–45 min, large effects (400–450% of baseline for noradrenaline and 700–1500% of baseline for dopamine), with a relatively rapid decline after the maximum (Figure 4). Although no comparative results have been included hinein this Bericht, the magnitude of the increases produced by amphetamine’s isomers are greater than those reported for classical reuptake inhibitors such as atomoxetine or bupropion, and there is no dose-effect ceiling to amphetamine’s actions (Bymaster et al.

Although the pharmacological effect of amphetamine welche medikamente enthalten amphetamin is predominantly mediated by monoamine release, this mechanism is complemented by reuptake inhibition and probably also inhibition of monoamine oxidase (MAO) that combine additively or synergistically to augment synaptic monoamine concentrations. The description of amphetamine as a ‘monoamine reuptake inhibitor’ often causes some confusion, and the difference between the mechanisms of amphetamine, which is a competitive reuptake transport substrate, and classical reuptake inhibitors is illustrated in Figure 3.
Immediate-release formulations may Beryllium 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.

Although amphetamine has been established as an effective treatment for ADHD, as well as other central nervous Anlage (CNS) disorders such as narcolepsy for decades, its use rein the UK (and rein the wider European context) has been rather limited in comparison with its widespread use hinein the USA.
As indicated above, it is the combination of the rapid Satz of increase and magnitude of effect that accounts for the powerful stimulant effects of amphetamine.
The association between amphetamine and severe cardiovascular events is controversial.
