Amphetamine’s effects on striatal dopamine efflux and locomotor activity are superimposable (Figure 5), that is, the rapid release of dopamine translates directly into an immediate and substantial increase of locomotor activity. Hinein the case of lisdexamfetamine, the more gradual and sustained increase hinein dopamine efflux was associated with a much smaller and visibly delayed locomotor response.
Other illicit amphetamine analogs such as copyright have a higher affinity for NET and SERT and are potentially more likely to cause hyperthermia, serotonin syndrome, and rhabdomyolysis. The risk of hyperthermia and rhabdomyolysis may become compounded by the association of copyright use rein dance clubs.[15][17]
amphetamine can lead to excessive use of it as a prescribed drug by the patient and the (mis)use of the prescription by others (diversion). For these reasons, all current amphetamine-type stimulant treatments are Controlled Drugs under the UK Misuse of Drugs Act 1971, with all members of being placed hinein Class B except methamphetamine, which welches recently placed into Class A because of fears of an explosion of recreational abuse similar to that seen rein the USA and Thailand.
Both isomers of amphetamine dose-dependently increased the extracellular concentrations of noradrenaline hinein the prefrontal cortex (PFC) and dopamine in 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 review, 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.
Based on observations that the isomers of amphetamine evoke very large and rapid increases hinein the efflux of dopamine and noradrenaline hinein the PFC and dopamine hinein the striatum, it was predicted that these drugs would be highly effective in the treatment of ADHD. This welches confirmed by reports of efficacy rein ADHD with durchmesser eines kreises
