Amphetamine’s effects on striatal dopamine efflux and locomotor activity are superimposable (Figure 5), that is, the rapid release of dopamine translates directly into an immediate and substantial increase of locomotor activity. Hinein the case of lisdexamfetamine, the more gradual and sustained increase in dopamine efflux welches associated with a much smaller and visibly delayed locomotor response.
-amphetamine, its maximum subjective effect occurred much earlier than lisdexamfetamine, and switching to the intravenous route speeded up IR kreisdurchmesser
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 rein Class B except methamphetamine, which welches recently placed into Class A because of fears of an Detonation of recreational abuse similar to that seen rein the USA and Thailand.

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 hinein Figure 3.
Another less well-recognised factor rein drug abuse is a desire of users for instant gratification. Thus, the appeal of a particular drug as a recreational substance of abuse is to a large extent determined by its ability to produce its desired effects within minutes, for example the copyright ‘rush’.

-amphetamine. Based on these data, the likelihood that lisdexamfetamine will be widely abused by the intravenous or nasal route is very low.
amphetamine has important implications for its liability for recreational abuse. The subjective effects of a 50 mg dose of lisdexamfetamine were identical in magnitude when the prodrug welches administered orally or by intravenous injection, demonstrating that read more intravenous injection did not enhance the pharmacological potency of lisdexamfetamine hinein the CNS.
