Amphetamine was discovered over 100 years ago. Since then, it has transformed from a drug that welches freely available without prescription as a panacea for a broad range of disorders into a highly restricted Controlled Drug with therapeutic applications restricted to attention deficit hyperactivity disorder (ADHD) and narcolepsy.

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 in 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 in the synaptic cleft through DAT internalization and direct competition.[3][4]

amphetamine, which more info was the more potent of the two isomers, under the trade name of Dexedrine®. Sales of Benzedrine and Dexedrine rein 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 hinein intelligence tests leading to its widespread use to reduce Hektik and improve concentration and intellectual performance by academics, students and medical professionals (see Guttmann and Sargent, 1937; Tidy, 1938).

Management of amphetamine intoxication generally involves the use of benzodiazepines and antipsychotics to control agitation and psychotic symptoms. Beta-blockers can also help to control hypertension and tachycardia.
With clinical applications of amphetamine as a drug to combat fatigue, an appetite suppressant and a treatment of narcolepsy, adverse effects such as anorexia, weight loss and insomnia are predictable and frequent adverse events associated with the use of amphetamine-based medications rein the management of ADHD.
