amphetamine-containing medications, especially MES-amphetamine, have been very widely used as treatments for ADHD. Familiarity with prescribed amphetamines together with the increased availability of more and more tamper-deterrent drug formulations to reduce the potential for abuse, for example Adderall XR®, have created a situation where rein the USA the abuse risk of durchmesser eines kreises-

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 was recently placed into Class A because of fears of an explosion of recreational abuse similar to that seen in the USA and Thailand.

Amphetamine is contraindicated hinein patients with hypersensitivity to any component of the drug formulation. Amphetamine is also contraindicated during or within 14 days of MAOI therapy, e.
The Na+ concentration gradient is maintained by Na+/K+ ATPase that pumps two Na+ ions out of the cell whilst simultaneously pumping rein one K+ ion. There are two pools of monoamine neurotransmitter within each Durchschuss of nerve terminal: the cytosolic Schwimmbecken that holds newly synthesised monoamines, and the vesicular Swimmingpool that stores the monoamines and from which they are released when neurones fire action potentials.

Finally, excess monoamines within the nerve Am ende gelegen are catabolised by the mitochondrial-bound enzyme, MAO. Inhibition of MAO would further augment the quantity of neurotransmitter that is available for retro-transport into the synapse. Amphetamine’s isomers have long been known to be inhibitors of this important catabolising enzyme (Mantle et al.

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 rein 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 hinein the synaptic concentrations of dopamine rein the basal striatum and mesolimbic Anlage of the human brain.
