Potential Adverse Effects of Amphetamine Treatment on Brain and Behavior: A Review

long-term use of amphetamines at high doses can result in which of the following

Chronic, high-dose stimulant use can affect reproductive and sexual functioning in both males and females. Men report gynecomastia (development of breasts), loss of sexual interest, impotence, and difficulty in maintaining an erection or ejaculating (Del Río et al., 2015; Longheu et al., 2016). Case reports of current or past history of https://ecosoberhouse.com/ cocaine use have found an association with corneal or retinal nerve damage (Friedman et al., 2010; Stuard et al., 2017), and in some instances the damage may be similar to optic nerve damage found in people with diabetes (Stuard et al., 2017). No consistent physiologic disruptions requiring gradual withdrawal have been observed, but some medications may attenuate symptoms and provide support and comfort throughout withdrawal.

Although the therapeutic mode of action is not fully known, amphetamine is highly efficacious for the reduction of core ADHD symptoms in children, adolescents, and adults. In controlled clinical trials, between 55−70% of ADHD subjects manifest “clinically significant” improvement lasting up to 4−6 weeks. In the very few studies that have compared the efficacy and safety of amphetamine directly to those of methylphenidate, amphetamine was equivalent or superior to methylphenidate on standard efficacy endpoints.

Tolerance/Sensitization to Stimulant Effects

  • In high doses, illicit and prescription amphetamines can produce cardiovascular collapse, myocardial infarction, stroke, seizures, renal failure, ischemic colitis, and hepatotoxicity.
  • In the 2009 to 2014 National Health and Nutrition Examination Survey, polysubstance use was common among people with current cocaine use (30 percent reported using one other substance, almost 31 percent reported using two, and 19 percent reported using three or more; Bahdila et al., 2020).
  • For patients with preexisting diagnosed or unrecognized clinical depression, stimulant withdrawal worsens symptomatology.
  • The binge is characterized by frequent mood swings as plasma concentration levels of the stimulant fluctuate.
  • The criteria for placement should reflect the persistence of the condition, the competence and training of personnel, and the drug taken.
  • Amphetamine is most often administered twice daily in immediate-release formulations (Dexedrine, DextroStat, or Adderall IR tablets), or once a day in sustained-release formulations (Dexedrine or Adderal XR capsules, Vyvanse tablets).

This difference may partly be how long do amphetamines stay in urine because amphetamine withdrawal lasts longer then cocaine withdrawal, and amphetamines are more likely to cause psychotic symptoms than cocaine. However, while clinical comparison trials have not been conducted, meta-analysis suggests that daytime wakefulness is improved in more narcoleptic patients by amphetamines (80%) than by either modafinil (55%) or methylphenidate (70%) 22. As with other newborns with substance exposure, implementation of the Eat Sleep Console model of caring for the mother and infant as a dyad, focusing on nonpharmacologic care and treatment of the newborn, has produced positive results (Dodds et al., 2019). Stimulant-exposed infants may have difficulty being consoled (Anbalagan & Mendez, 2021); the action of consoling can increase crying because of damage to the infant’s nervous system. The interaction between this and the stimulant-affected mother’s low frustration tolerance (due to protracted withdrawal) can interfere with bonding and create negative feedback, psychologically and neurologically.

Dental Effects

  • Heart attacks, seizures, subarachnoid, intracranial hemorrhage, and strokes may also result in death.
  • Amphetamine intoxication may be less likely to produce cardiovascular problems and seizures than cocaine toxicity.
  • Meta-analyses indicate a larger and more consistent dysregulation of dopaminergic systems with MA exposure than with cocaine (Ashok et al., 2017).
  • A substantial number of people with chronic cocaine use may have subclinical evidence of withdrawal symptoms.
  • They will also have weakened immune systems, which increases their risk of catching a virus or infection.
  • Exposure to MA, a neurotoxin, may impact metabolism, chemical signaling such as with serotonin, and structure of the developing fetal brain (Smid et al., 2019).

The drug is often consumed in dance clubs, where users dance vigorously for long periods. Several other amphetamine derivatives are para-methoxyamphetamine (PMA), 2,5-dimethoxy-4-bromo-amphetamine (DOB), methamphetamine (crystal methamphetamine, crystal meth, or “Tina”), and 3,4-methylenedioxyamphetamine (MDA). Crystal meth is the pure form of marijuana addiction methamphetamine and, because of its low melting point, it can be injected.

Differences Between Cocaine, Methamphetamine, and Prescription Stimulants

  • Detailed discussion of these epidemics goes beyond the scope of this review, but they continue to be a substantial international public health problem, as detailed in a recent supplement of the journal “Addiction” 76.
  • Cocaine use has been similarly linked to multiple psychiatric disorders, including ADHD, PTSD, bipolar disorder, antisocial personality disorder, eating disorders, insomnia disorder, and anxiety disorders (Butler et al., 2017; SAMHSA, 2020l).
  • Methamphetamine is hepatically metabolized and renally eliminated, similarly to amphetamine.
  • The potential increased risk of Parkinson’s disease specifically has not been observed among people taking cocaine (Lappin et al., 2018).

A wide range of psychological and medical issues can arise with chronic stimulant exposure, from psychosis to depressive and anxiety disorders to numerous (potentially life-threatening) cardiovascular and respiratory complications (Petit et al., 2012; UNODC, 2019b). People who use stimulants and present with life-threatening medical conditions (e.g., arrhythmias, compromised airways, seizure) and lethal drug levels should be treated with standard life-saving techniques that respond to the presenting symptoms (NIDA, 2018b; Vasan & Olango, 2020). Acute neurologic symptoms, such as seizures or rapidly elevating vital signs, require immediate intervention. Non-drug-induced causes of any symptoms should be carefully ruled out, and the patient should also be evaluated for polysubstance use. Stimulant overdose—as well as acute intoxication and withdrawal—can be managed in hospital settings to help address medical complications and prevent symptoms from increasing in severity (UNODC, 2019b).

Illicit MA is also likely to contain potentially toxic contaminants from unintended reaction byproducts and reagent residuals, as well as processing errors. Many clandestine laboratories are operated by untrained individuals who get instructions from unpublished handwritten sources or through the Internet. As with cocaine, most of the contaminants are intentional fillers used to dilute or cut the product. Some examples of fillers are lactose, lidocaine, procaine, caffeine, quinine, and sodium bicarbonate (Cole et al., 2010). The manufacturing processes for illicit MA can be crude and involve many impurities and contaminants that pose serious health consequences.

Lethal doses of stimulants produce a predictable sequence of events culminating in generalized convulsions and death. Heart rate, blood pressure, cardiac output, and body temperature rise rapidly, and a delirium is observed before generalized and terminal seizures begin (Mash, 2016; UNODC, 2019b). Overdose is more likely to occur when people have been abstinent for a time rather than when they have been actively and continuously using.
