Agitation and seizures are controllable with benzodiazepines, phenothiazines, pentobarbital, and propofol. A beta-blocker such as propranolol can help to manage cardiac tachyarrhythmias. Consider intravenous nitroprusside (start at 0.5 to 1 mcg/kg per minute and titrate as needed) for severe hypertension. Intravenous fluid should be given as it counters hyperthermia, assists in maintaining renal function, and helps promote the elimination of amphetamine and its analogs. Concurrent use of amphetamine and serotonergic agents that inhibit CYP2D6 may increase amphetamine exposure and increase the risk of serotonin syndrome.

  • A less significant mechanism may include their ability to block the reuptake of catecholamines by competitive inhibition.
  • Fenproporex is the world’s second most popular amphetamine-like anorectic medication 30,36, and its derivatives are used in the treatment of male-type obesity.
  • To avoid withdrawal symptoms, take your medication exactly as your provider prescribed it to you.
  • They are most often used to treat attention-deficit hyperactivity disorder (ADHD) and narcolepsy.

In 2020, about 5.1 million people in the United States reported misusing prescription stimulants, such as Adderall, within the past year.

Doctors prescribe amphetamines for conditions such as ADHD, obesity, narcolepsy, and depression.

Methamphetamine Toxicity

There are case reports regarding the Takotsubo cardiomyopathy (TTC), also known as stress-induced cardiomyopathy, which is triggered by amphetamine overdose. In one case, a patient presented to the emergency department after ingesting 30 amphetamine salt tablets with symptoms of chest pain and shortness of breath. At the time of presentation, cardiac enzymes were elevated, the electrocardiogram was unremarkable, and ejection fraction (EF) was 25% to 30% with severe hypokinesis. However, 24 half life of amphetamines hours later, symptoms were resolved, and a repeated echocardiogram performed three days later showed an EF of 60% with no regional wall motion abnormalities. Overall, the therapeutic application of amphetamine-type stimulants continues to evolve, and further research is needed to fully understand their mechanisms of action, dosage requirements, and potential risks and benefits for various psychiatric disorders. Each patient is different, and each treatment with MAS may induce different results and TEAEs.

The Therapeutic Potential of Amphetamine-like Psychostimulants

A study of children receiving licit stimulants in the Netherlands found that 90% of them were diagnosed with ADHD 32. Medical use of stimulants is highest in North America (1 to 2 % of the population), and Australia, particularly the state of Western Australia (2.4%), with somewhat lower values in Europe (0.8 to 1.7%). This frequency of amphetamine use parallels regional differences in the prevalence estimates of ADHD 33. In 2004, 70% of the stimulant prescriptions for children in Western Australia were for d- amphetamine. However, as methylphenidate was approved for government subsidies in late 2005, its use has probably since increased 33. In 2000, the number of prescriptions for amphetamine exceeded eight million, a 1600% increase over nine years.

However, another study showed conflicting results, as the mean scores on the Fugl-Meyer motor scale were not significant for the amphetamine group compared with the placebo group. P-cresol can hinder myelination by obstructing myelin gene expression and differentiation 41. Furthermore, P-cresol can act as an inhibitor of dopamine beta-hydroxylase, affecting the dopaminergic system, with a single intravenous administration of P-cresol elevating the dopamine metabolism 41. In this context, it is important to note that dopaminergic dysfunctions play a central role in the pathophysiological mechanisms underlying PTSD 41. An abnormal dopamine level in the prefrontal cortex may contribute to the disruption of the top-down inhibitory control exerted by this region over the limbic regions, a key factor responsible for the occurrence of both intrusion and hyperarousal symptoms 41. When it comes to PTSD, modifications in gut microbiota have also been shown to enhance vulnerability to trauma by promoting the production of specific metabolites that influence various brain functions and systems 41.
