INTRODUCTION
In the last decade, there has been a growing concern in the academic world regarding the continuous use of psychostimulants to improve school performance amongst undergraduate students1. These substances are characterized by their capacity to stimulate the Central Nervous System (CNS)2, enhancing attention and concentration. Among these substances, ‘energy beverages’ (drinks based on caffeine, guaranine, cola, and taurine), medications used for weight loss, and the drugs indicated for the treatment of attention deficit and hyperactivity disorder (ADHD) and narcolepsy stand out 2),(3.
The medications more frequently utilized to improve cognitive performance are those indicated for the treatment of ADHD, which is characterized by loss of attention, mental organization, and hyperactivity/impulsivity, starting at childhood and being able to persist up to adult life, which can harm an individual’s social, academic, and professional life4. The ADHD pharmacological treatment includes using Methylphenidate (MPH)5, a stimulant drug sold in Brazil under the commercial names Concerta®, Ritalina®, and Ritalina LA®(6, as first-class medications for therapeutic intervention2),(5),(7),(8),(9. This drug promotes an increase in attention and the control of behavioral impulses; however, it has the potential for the development of drug dependence when inadequately used6. Therefore, the recommendation for its use should follow strict criteria, after a medical and psychological evaluation taking into account family history, development during childhood, school performance, an analysis of the use of other psychoactive substances, as well as the level of intelligence of the personality10.
The use of stimulants to enhance mental activity has been described as an option to deal with the demands that undergraduate school requires and to improve academic performance2, generating concerns about the risks to the individuals’ health and quality of life. Recent investigations carried out at the University of Rhode Island, Brown University, and at the Rhode Island Memorial Hospital studied the consequences of the unprescribed use, of Adderall® (a mixture of amphetamine salts, also used to treat ADHD) by undergraduate students. The authors verified that the attention capacity improves, albeit to the detriment of the working memory functions, which, in turn, could compromise the performance of daily tasks, solving problems, and social relations as well1.
Amongst the university courses, a degree in Medical Science is considered one of the most demanding in respect to the performance of its students2),(11. Their journeys begin the moment they choose the profession, going through pre-college preparatory courses, competing with others to get into a university, and after that having to keep up the high performance during the entire graduation11. Most of the students arrive at the University hoping that the level of continued dedication demand will slack down and gets frustrated when they realize that, quite to the contrary, the rhythm of studies will continue at a very high rate of demand11. Besides this, other factors such as sleep and leisure deprivation contribute to stress and low academic performance2. Committed to a strenuous routine, the students may resort to means to attain efficiency in the course activities, amongst them the use of brain stimulants such as the MPH2.
This subject is essential to all Higher Medical Education institutions and those that render student support. This essay aims to make a literature revision concerning the usage of MPH among medical students without a doctor’s prescription, seeking a better understanding of the aspects of using psychostimulants and promoting preventive actions to offer medical students better learning conditions and quality of life.
METHOD
A comprehensive revision was carried out in international and Brazilian national literature, focusing on articles published in the last seven years (January 2013 through December 2019). In addition, the authors included articles written in English, Spanish and Portuguese, about the usage of MPH without medical indication by medicine students based on data made available by Pubmed/Medline and Scielo, using the following as keywords or key expressions in these three languages, respectively:
Medical Students; Methylphenidate; Stimulants and Cognitive Enhancement.
Estudiantes de Medicina; Metilfenidato; Estimulantes; Mejora Cognitiva.
Estudantes de Medicina; Metilfenidato; Estimulantes; Aprimoramento Cognitivo.
To this effect, a selective structure was established, comprising four stages, which included articles focusing on the scope of the research, follows: title of the article, analysis of the abstracts, dynamic reading of the articles, and complementary search in the bibliographic references of the selected ones, which met the same appropriate criteria concerning the topic, abstracts, and dynamic reading.
RESULTS
In total, 224 articles were found, of which 09 were from the Scielo database, and 215 from Pubmed. The repeated articles or the ones that did not address MPH use by medical students without clinical orientation were excluded, as shown in Figure 1.
The publications concerning cognitive intensifiers that included the use of MPH were maintained, resulting in 20 articles that were revised and had their bibliographical references assessed. In this process, 69 articles were submitted to the forementioned screening method, plus another five articles to be analyzed. Thus, in total, 25 articles were selected for this review (Table 1) and the highlights of the review are presented in Chart 1.

Topic | Description |
---|---|
Epidemiological data | Significant variability in use rates (3% to 47%), depending on the location of the study and methodological differences in data collection (use throughout life or after entering University; prescribed or self-recommended use; frequent use or experimentation). |
Indications of an average rate of use in life are around 10%. | |
Conflicting data regarding gender distribution: some studies point to greater use by men, and others have found no differences. | |
Data are inconclusive regarding the course period most associated with the use. | |
Most studies suggest a preponderance of use after entering University. | |
Motivations for use | Unlike medical students’ usual consumption pattern of other psychoactive substances (recreational use and in social contexts), psychostimulants, particularly MPH, are mostly related to the search for increased waking time and improved concentration, attention, memory, and academic performance. |
Use of other substances | Some studies indicate higher consumption rates among students who use other icit and illicit substances - particularly alcohol - however, there are little data on the risks of interaction and abuse or dependence rates. |
Risks related to use | Few studies address the topic, but they mainly point out increased anxiety and problems with sleep. There is no confirmation of benefits in cognitive functions, only increased waking time. |
The role of the medical school | Articles point to concern about how university disciplines present the substances to the students, as there are indications of greater use after its mention in the initial years of the course. |
Other studies indicate the need to discuss the topic with students, mainly because they describe behavior facilitated by peers. | |
Additionally, they highlight the importance of addressing the risks of use, self-prescription, and the ethical aspects involved. | |
Few articles discuss, although they point out, the need for studies on issues related to medical education, content, forms of teaching/learning, competitiveness, and mental health of future doctors. |

DISCUSSION
The study indicated significant variability in the frequency of consumption, related to the pattern of use investigated, use with or without indication, before or after entering University and country where the study was performed. Among the assessed articles, the students from Latin American countries were the ones who showed a higher prevalence of MPH use. A Puerto Rican survey showed the highest prevalence (47.4 %)12, followed by 45% of the students interviewed in a Paraguayan school, of which 33% used the drug without adequate clinical indication13. Then comes a total of 34.2% of the students from a medical school in the Rio Grande do Sul, Brazil, of which 23% used it without adequate indication14. The other two studies carried out in Brazil2),(7) indicated higher rates of use when compared to other countries such as the USA, with 18%15, Israel8 and Africa with 17%16, North of Iran with 11%17 and a study in Pakistan with 9%18.
The most recent study in Brazil, published in 2016, showed consumption (at least once in the lifetime) of 20%2 of the students, and another study carried out in Rio de Janeiro7 in 2013 indicated a rate of 23.7% of use during the lifetime of those students that participated in the study. At a literature review carried out in 2013, it was described, this same group of students, a percentage of use of 3 to 16%19, while 14.5%19 admitted they had already used MPH to improve academic performance.
Seven studies were carried out on the difference in use between the genders, without significant differences. Five, however, indicated a higher rate of consumption of psychostimulants (including MPH) by the male gender 3),(9),(15),(17),(20, while one of these specified the use of MPH9. Only one article described a higher prevalence of use by the female gender21.
Some studies suggest that the majority of the medical students that use MPH started using it after entering the University. A study carried out in the USA says that 57% of the interviewed students who had already used MPH declared having started using it during college15 and a study carried out in Brazil pointed to the fact that 64% of the students with a background of use claimed they started using this substance during the medical course2. In a North American study performed with students of Osteopathic Medicine, the authors found that the frequency of students that admitted the use of psychostimulants without medical indication was higher than the diagnosis rate in the population22.
In a study carried in a University in the Brazilian state of Minas Gerais, half of the students who used psychostimulants did it before the exams21. Another study in Puerto Rico found a rate of 60.3%12. These findings emphasize that the stimulants seem to be considered a facilitator for “good” results in the exams21. Other studies also pointed out that the motivation leading to the use of MPH without a medical indication aimed at better academic performance23, increasing waking hours, improving concentration, attention capacities, and extended memory2),(3),(7),(8),(9),(12),(13),(14),(15),(17),(18),(21),(24),(25. In addition, research in Iran revealed the role of social groups in the indication of brain stimulants17, also considered a motivator for consumption without medical indication.
A Belgium study of 2019, set to investigate what would be “behind” the need of the students seeking cognitive enhancement, questioned 3,159 students that used non-therapeutic stimulant medications26. The authors pointed out that the clearer the perception that the medical school is a competitive environment, the more significant the levels of stress and the higher the probability for inadequate stimulant use. The research reveals that, contrary to expectations, the association of competition with stress was significantly stronger in those students who wanted to become general practitioners, with the consequent use of stimulants, compared to those aiming to have a medical specialization24. In another study, medical supervisors and medical students reported greater use of psychostimulants, without medical indication, than the Pharmacy course students. These three groups showed stress rates roughly two times higher than the adult population in general27.
A study carried out in the state of Rio Grande do Sul, Brazil, determined that 14.3%14 of the users of stimulants were associated with alcohol consumption, and 5.7% admitted using MPH in parties as well14. These findings suggest that the most frequent use was not related to social activities or parties, such as the other psychoactive substances, but was probably associated with academic performance improvement. This research also realized that MPH users who used it together with alcohol, with or without a medical prescription, showed alcohol consumption patterns that were considered a health risk14. The MPH, when associated with alcohol, produces a euphoric effect decreases the sensation of inebriation or drunkenness14. However, this combination produces a toxic metabolite, and its effect on the organism remain little known14.
The medical schools in South Africa adopted the posture of not providing information about the indications and effects of MPH in the first five semesters of the course28. They based this decision on research carried out in 2017, in which the higher percentage of consumption was reported by students attending the third year of medical school (18.5%), raising the hypothesis that the knowledge about the pharmacological effects of the substance can contribute to its demand and misuse28.
Brazilian and Paraguayan studies found a higher rate of psychostimulant consumption (including caffeine, methylphenidate, modafinil, piracetam, energy drinks, and amphetamines) by the students attending the first years of medical school. In the state of Rio Grande do Sul, the rates were decreasing according to the year of the course: from 69.2% in the 1st year, to 61.5% in the 2nd, 40.8% in the 3rd year, and 34.8% in the 4th year2 moreover, in the state of Minas Gerais the rates went from 65.78% in the 1st year, to 64.10% in the 2nd and 41.02% in the 3rd year21; furthermore, in Universidad Internacional Tres Fronteras, in Paraguay, the rates were 22% in the first year, 32% in the second, 18% in the third and 14% in the fourth and fifth years13, differently from those observed in the American28 and Puerto Rican12 studies, which showed similar ratesamong all years.
One aspect that deserves special attention is the obtaining of a controlled medication without an appropriate prescription. MPH is sold only under medical prescription in Brazil and other countries. In Brazil, the prescription necessarily requires the yellow prescription pad for controlled drugs (A3). In addition, the packaging has a black strip across the box, which indicates that it can only be sold with a medical prescription, and it carries information concerning the risk of chemical and psychological dependence according to specifications 344 of SVS/MS Ordinance of May, 199829. Despite these measures, a recent study showed that 24.3% of the MPH user students obtained it through a ‘self-written prescription,’ and 15% obtained it from a friend12.
This fact flashes a red alert on the risks of self-medication and the importance of medical assessment for the consumption of prescribed medications by undergraduate medical students. An Iranian study pointed to a rate of 4.9% related to the misuse of medicaments requiring a medical prescription (in this study, opioids, tranquilizers, and MPH were taken into consideration)20. Considering that all of them are medications that offer risks of dependence, it is relevant to question whether the easy access to these drugs can contribute to this self-medication behavior and the trivialization of the use by future doctors.
Despite the known potential dependence properties of the substance, the only cross-sectional study carried out in the state of Rio de Janeiro, Brazil, showed a prevalence of 10.8%7 of students that claimed they had to increase the dose to attain the same effect, suggesting a possible development of tolerance, one of the diagnostic criteria for dependence5. Although the included articles have not explored MPH dependence of in detail, suggestions were there for broader research on this topic14. Some references deal with the dependence on this medication as something more theoretical than practical3; however, the increase in consumption by the young people seeking cognitive enhancement deserves attention and care, for its use without therapeutic indication can raise the potential of dependence. According to Dafny5, sensitization can increase the experienced effects when compared to those experienced at the first use of the same dose, which can be considered an additional warning signal for the need to evaluate groups regarding the chemical dependence.
An US article published in 2013 measured the consumption pattern of stimulants, with a predominance of amphetamine salts and MPH15. Among the users, an average frequency of drug use ranged from 10 to 12 occasions during a 30 day period, which consisted in most cases in oral administration (92%), with a smaller percentage (18%) of inhaled administration, associated or not with oral administration13. In 2018, an Iranian study demonstrated that most interviewed individuals consumed these substances through an oral route (79.6%). However, 6.1% said they consumed it by an intravenous route and 2% by the inhaled route17. Thus, although the selected studies indicate the use of MPH primarily by oral administration, it is essential to follow a possible increase in the other means of administration of these substances, keeping in mind that the use of intravenous or intranasal drugs implies more severe damage and potential risks such as of overdose.
Addressing the possible consequences of MPH use, Beyer30 points to the need for more comprehensive studies that an demonstrate whether the cognitive improvement justifies the risk of eventual harm to the body. Moreover, a study with undergraduate medical students disclosed the presence of side effects, among them, body pain, headache, tachycardia, anxiety18, cardiac arrhythmias and glaucoma30 in African undergraduate students, and in Paraguayan undergraduate students, tachycardia, decreased appetite and tremors13.
The therapeutic effects of MPH on those suffering from ADHD appeal to the students without such diagnosis2),(10. Nevertheless, using the substance as an intensifier to attain success in exams31 can harm the cognitive functions, such as the capacity to solve problems1, in addition the risk of acquiring a chemical dependence5),(6),(19. These consequences can, in turn, worsen academic performance, making what seemed an apparent advantage a new problem to be dealt with31.
Besides this, an Indian study addressed some ethical questions concerning the prescription of cognitive stimulants to individuals who do not need them, creating an even more severe behavioral problem when they are self-prescribed by future doctors30),(32. Furthermore, this study proposes a reflection about the competition for higher grades among medical students and the use of medications to boost this performance, since the stimulant does not create skills, but rather intensifies a condition that already exists in a person, which can be improved through different strategies, not of a pharmacological nature and exempt from acute and chronic risks31.
National33),(34 and international35),(36 studies have pointed out that the required workload and the predominantly transmitting pedagogy, combined with impacts on lifestyle, social relationships, and poor sleep quality, have been associated with emotional exhaustion, dehumanization, and feelings of dissatisfaction and inefficiency among medical students. The students report factors related to a decrease in their quality of life, including competition, unprepared teachers, excess of activities, medical school schedules that demand exclusive dedication, contact with pain, death, and suffering, and harsh social realities, as well as frustrations with the program and insecurity regarding their professional future. The scarcity of time for studying, leisure activities, relationships, and rest can influence the use of substances, including psychostimulants. These data indicate the necessity of national quantitative and qualitative studies to discuss these difficulties in our universities and subsidize ways of approaching them adapted to our scenario.
CONCLUSION
An analysis of the articles reveals that MPH misuse consumption rates among medical students is a matter of concern. The undergraduate medical school students that use the substance without medical indication, generally speaking, resort to MPH to enhance academic performance, both in the study and when facing exams. Few studies have evaluated the cognitive, behavioral, and psychological risks, including the dependence associated with such consumption patterns. Finally, some studies addressed the ethical aspects related to the context of use, besides the trivialization of self-prescribed medicines.
Considering this scenario, we highlight the importance of prevention actions inside medical schools, by providing information concerning the risks of MPH consumption without clinical indication, educational programs that can help to deal with the University routine, behavioral strategies aimed to improve cognitive performance, with emphasis on measures covering sleep hygiene, study organization, mnemonic activities and the valorization of measures that improve quality of life, such as physical and recreational activities. Such initiatives can stimulate the self-confidence of innate capabilities and contribute to maintain the future doctors’ physical and mental health.
