Dextroamphetamine may impair your thinking or reactions. The amphetamine molecule exists as two enantiomers,[note 1] levoamphetamine and dextroamphetamine. [23] It also shares many chemical and pharmacological properties with human trace amines, particularly phenethylamine and N-methylphenethylamine, the latter being an isomer of amphetamine produced within the human body. [85][99][100] Once FosB is sufficiently overexpressed, it induces an addictive state that becomes increasingly more severe with further increases in FosB expression. [note 16]. [61][67] Due to the potential for reversible growth impairments,[note 6] the USFDA advises monitoring the height and weight of children and adolescents prescribed an amphetamine pharmaceutical. Dextroamphetamine is a central nervous system stimulant. Skip the missed dose if it is almost evening. [44] Therapeutic doses of amphetamine also enhance cortical network efficiency, an effect which mediates improvements in working memory in all individuals.

[98], A systematic review and meta-analysis from 2019 assessed the efficacy of 17 different pharmacotherapies used in randomized controlled trials (RCTs) for amphetamine and methamphetamine addiction;[118] it found only low-strength evidence that methylphenidate might reduce amphetamine or methamphetamine self-administration. [106] Most of the research on gene regulation and addiction is based upon animal studies with intravenous amphetamine administration at very high doses. [154][156], The oral bioavailability of amphetamine varies with gastrointestinal pH;[61] it is well absorbed from the gut, and bioavailability is typically over75% for dextroamphetamine. [80][138] According to the same review, there is at least one trial that shows antipsychotic medications effectively resolve the symptoms of acute amphetamine psychosis. The military did not accept this explanation, citing the lack of similar incidents.

[41], In 2015, a systematic review and a meta-analysis of high quality clinical trials found that, when used at low (therapeutic) doses, amphetamine produces modest yet unambiguous improvements in cognition, including working memory, long-term episodic memory, inhibitory control, and some aspects of attention, in normal healthy adults;[42][43] these cognition-enhancing effects of amphetamine are known to be partially mediated through the indirect activation of both dopamine receptor D1 and adrenoceptor 2 in the prefrontal cortex. [14], The half-lives of amphetamine enantiomers differ and vary with urine pH. Aurobindo refuses to provide updated availability information. The 95%confidence interval indicates that there is a 95%probability that the true number of deaths lies between 3,425 and 4,145. [sources 10] Amphetamine has a variety of excreted metabolic products, including 4-hydroxyamphetamine, 4-hydroxynorephedrine, 4-hydroxyphenylacetone, benzoic acid, hippuric acid, norephedrine, and phenylacetone. [106] This suggests that medical use of amphetamine does not significantly affect gene regulation. [14] The immediate-release and extended release variants of salts of both isomers reach peak plasma concentrations at 3hours and 7hours post-dose respectively. "[127] This review noted that withdrawal symptoms in chronic, high-dose users are frequent, occurring in roughly 88% of cases, and persist for 34weeks with a marked "crash" phase occurring during the first week. [120][121] Amphetamine addiction is largely mediated through increased activation of dopamine receptors and co-localized NMDA receptors[note 9] in the nucleus accumbens;[98] magnesium ions inhibit NMDA receptors by blocking the receptor calcium channel. [note 11][129], In rodents and primates, sufficiently high doses of amphetamine cause dopaminergic neurotoxicity, or damage to dopamine neurons, which is characterized by dopamine terminal degeneration and reduced transporter and receptor function. [103], Drug tolerance develops rapidly in amphetamine abuse (i.e., recreational amphetamine use), so periods of extended abuse require increasingly larger doses of the drug in order to achieve the same effect.
