Both isomers of amphetamine dose-dependently increased the extracellular concentrations of noradrenaline rein 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 rein 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.
Amphetamine has high misuse/abuse potential. All interprofessional team members (clinicians, nurses, pharmacists, behavioral therapists) involved rein the care of a patient taking amphetamines should monitor closely for signs of medication misuse. As a schedule II controlled substance, there are no refills for amphetamine, which may necessitate monthly appointments with the prescribing physician. A cardiologist consult may be necessary for evaluating patients with potential cardiac concerns before the initiation of amphetamines.
amphetamine. This difference rein PK characteristics had a profound impact on the pharmacological effects of these two compounds in rats (Figure 5). Lisdexamfetamine produced a gradual and sustained increase hinein striatal dopamine efflux, whereas the increase produced by IR kreisdurchmesser-

-amphetamine makes an important contribution to its pharmacology. How lisdexamfetamine’s distinctive pharmacokinetic/pharmacodynamic profile translates into sustained efficacy as a treatment for ADHD and its reduced potential for recreational abuse is also discussed.
It is currently being developed for clinical use in treating ADHD rein a number of European countries. here The metabolic route of lisdexamfetamine is unusual because after absorption into the bloodstream it is metabolised by red blood cells to yield d-
It is well known that recreational drug abusers and dependent users generally administer psychostimulants at doses several-fold higher than those stipulated for therapeutic use. Furthermore, to achieve its greatest pharmacological effect, the maximum quantity of drug must Beryllium delivered into the CNS in the shortest possible time. It is this imperative which causes drug abusers to progress from relatively safe methods of self-administration, such as oral ingestion, onto increasingly dangerous routes, for example snorting copyright, smoking (‘crack’ copyright or ‘copyright’) or intravenous injection.

As indicated above, it is the combination of the rapid Tarif of increase and magnitude of effect that accounts for the powerful stimulant effects of amphetamine.
Volkow and colleagues have performed an enormous body of research using PET and other brain imaging techniques to explore the relationship between DAT occupancy, synaptic dopamine concentration and dopamine D2 receptor occupancy for psychostimulant drugs of abuse. Although the dopamine release hypothesis of drug reinforcement proposed by Di Chiara and Imperato (1988) based on experiments performed in rats and then extended rein humans by Volkow and colleagues (1997, 1999a) has its limitations, it is now well accepted that euphoria, psychostimulation and reinforcement produced by stimulant drugs occur when there are rapid and substantial increases in the synaptic concentrations of dopamine hinein the basal striatum and mesolimbic system of the human brain.
