In his 1946 review, Bett commented on the widespread use of ‘energy pills’ by the allied forces in World War II, estimating that 150 million Benzedrine tablets were supplied to British and American service personnel during the course of the global conflict. In spite of considerable coverage hinein the medical literature and the popular press describing the powerful central effects of these new drugs, the addictive potential of amphetamine welches largely dismissed (Weiher Bett, 1946; Guttmann and Sargent, 1937; Tidy, 1938).
We have developed a systemic approach that brings together the human networks, processes and scientific tools necessary for collecting, analysing and reporting on the many aspects of the European drugs phenomenon.
stimulation of striatal dopamine transmission by amphetamine: evidence from microdialysis and Fos immunohistochemistry. J Neurosci
amphetamine is the less potent of the two isomers, its pharmacological efficacy should not be underestimated. Cheetham et al. (2007) reported that both isomers were capable of increasing striatal dopamine efflux by >5000% of baseline values, with these effects reaching a maximum within around 45 min. Hinein contrast, the maximum increases hinein dopamine efflux achieved by classical dopamine reuptake inhibitors (e.g. bupropion and GBR 12909) are five to tenfold smaller, and often take longer than an hour to reach their peak (Bredeloux et al.
The net result of this activity is increased efflux of dopamine into the synaptic cleft and reuptake inhibition hinein the synaptic cleft through DAT internalization and direct competition.[3][4]

Due to their ability to produce powerful euphoric effects, amphetamines are common drugs of abuse. All major drugs of more info abuse increase dopamine concentrations in 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.

-amphetamine’s onset of action and increased its potency. Although increasing the dose of lisdexamfetamine enhanced its efficacy, it also progressively delayed its time of peak effect.
Amphetamine’s verschiederlei pharmacological actions translate not only into therapeutic efficacy, but also into the production of adverse events and liability for recreational abuse. Accordingly, the balance of benefit/risk is the key challenge for its clinical use. The Bericht charts advances in pharmaceutical development from the introduction of once-daily formulations of amphetamine through to lisdexamfetamine, which is the first 2r
