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 in the USA the abuse risk of d-

Cardiac status should have an assessment before initiating therapy rein patients with known cardiac abnormalities. Patients with exertional chest pain, shortness of breath, pathologic heart murmurs, or any other signs and symptoms suggestive of cardiac disease should undergo full cardiac assessment, as should any patients with a family history of cardiomyopathy, arrhythmias, or ECG abnormalities such as long QT syndrome.
A comparison of the mean peak increases rein systolic and diastolic blood pressure produced by intravenous versus oral administration of 50 mg lisdexamfetamine.
Although the pharmacological effect of amphetamine 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.
Einige wenige Amphetamine sind nicht je den medizinischen Indienstnahme zugelassen und werden illegal hergestellt ebenso verwendet.
Due to their ability to produce powerful euphoric effects, amphetamines are common drugs of abuse. All major drugs of 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 website the concentrations seen for natural rewarding stimuli.

amphetamine, which welches the more potent of the two isomers, under the trade name of Dexedrine®. Sales of Benzedrine and Dexedrine hinein chemist stores were unrestricted until 1939, when these drugs could only be obtained either on prescription from a registered medical practitioner or by signing the Poison Register (Bett, 1946). The cognitive-enhancing properties of amphetamine were quickly recognised, with reports of Benzedrine producing improvements rein intelligence tests leading to its widespread use to reduce Nervosität and improve concentration and intellectual performance by academics, students and medical professionals (Weiher Guttmann and Sargent, 1937; Tidy, 1938).
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.
Amphetamine’s allerlei 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.
