RESUMEN

Objectives: This study aimed to make a bibliographic update on the already published data on bumetanide, addressing the main information on its use in Autism Spectrum Disorder (ASD). Methods: This was an integrative narrative review in which the following databases were used: Web of Science, MEDLINE, ScienceDirect, and Scielo. The descriptors used were: Autism Spectrum Disorder, Autistic Disorder and Bumetanide. It was considered only articles published in English and French. Original articles, randomized clinical trials, case reports, and review articles were included. Results: The results show that the use of bumetanide alters regions of the brain linked to the positive development of language, improvement of visual contact, improvement in social interactions, among others. Studies are also concerned about the safety and efficacy of bumetanide in ASD since several adverse effects have been reported. The most frequent were hypokalemia, polyuria, and loss of appetite. Conclusion: Bumetanide has proven as effective in improving some important symptoms in ASD, especially linked to language and social interaction, however, studies with larger groups of patients and with longer treatment and observation time are needed to confirm the efficacy and clarify the safety profile in use for people with ASD.


Objetivo: O objetivo deste trabalho foi fazer uma atualização bibliográfica sobre os dados já publicados da bumetanida, abordando as principais informações sobre seu uso no Transtorno do Espectro Autista (TEA). Metodologia: Foi realizada uma revisão do tipo narrativa integrativa, da qual foram utilizadas as bases de dados: Web of Science, MEDLINE, ScienceDirect e Scielo, com a utilização dos seguintes descritores: Autism Spectrum Disorder, Autistic Disorder e Bumetanide. Foram considerados apenas artigos publicados nas línguas inglesa e francesa. Foram incluídos artigos originais, ensaios clínicos randomizados e relatos de caso. Foram excluídos artigos de revisão. Resultados: Os resultados mostram que o uso da bumetanida altera regiões do cérebro ligadas ao desenvolvimento positivo da linguagem, melhora do contato visual, melhora nas interações sociais, entre outros. Os estudos também se preocupam em relacionar a segurança e a eficácia da bumetanida no TEA, do qual foram relatados diversos efeitos adversos, sendo os mais frequentes a hipocalemia, a poliúria e a perda de apetite. Conclusão: A bumetanida mostrou ser eficaz na melhoria de alguns importantes sintomas no TEA, especialmente ligados à linguagem e interação social, entretanto, estudos com grupos maiores de pacientes e com maior tempo de tratamento e observação são necessários para confirmar a eficácia e esclarecer o perfil de segurança no uso para pessoas com TEA.

RESUMEN

OBJECTIVE: Mexico has the second largest prevalence of obesity among adults worldwide, a condition especially affecting the low-income population. There is a pressing need to improve therapeutic options for weight loss. Phentermine is an old and low-cost agent given as an adjuvant therapy for obesity for a 12-week period, at an initial dose of 15 mg or 30 mg. However, there are no precise guidelines on the suitability of both the starting dose and the continuation of treatment for 6 months. The aim of this study was to evaluate the 3- and 6-month efficacy and safety of phentermine in obese Mexican patients to elucidate the aforementioned. MATERIALS AND METHODS: In this prospective, multi-center, open-label study, 932 obese adults received 15 mg or 30 mg phentermine once daily for 6 months. RESULTS: 30 mg phentermine was more effective than 15 mg phentermine in improving anthropometric variables in the 3-month follow-up, but not after completing the 6-month treatment period. Nearly 40% of 3-month non-responders reached a body weight reduction of at least 5% at 6 months. Conversely, ~ 65% and 25% of 3-month responders maintained or improved, respectively, their body weight reduction with long-term phentermine. Potential tolerance as weight regain was ~ 10% from 3 to 6 months. None of the doses increased cardiovascular risk, although mild-to-moderate adverse events were more frequent with 30 mg phentermine. CONCLUSION: 30 mg phentermine was more effective than 15 mg phentermine after 3 months, but not at 6 months of treatment. An important number of subjects could benefit following the therapy from 3 to 6 months.

RESUMEN

Sibutramine is a non-selective serotonin-norepinephrine reuptake inhibitor orally administered for weight loss. In a previous study, we showed pharmacological mechanisms involved in the reduction of sperm quality and fertility of rats exposed for 30 days to this anorexigen in the light phase of the light-dark (l/d) cycle. It is already known that rodents are nightlife animals, with higher metabolic activity during the dark phase than in the light phase of the light-dark (l/d) cycle. Thus, the present study aimed to investigate whether the deleterious effects on reproductive parameters after sibutramine administration would be enhanced after a shorter period of exposure during the dark phase of the l/d cycle. For this, adult male Wistar rats were treated with sibutramine (10 mg/kg/d) or vehicle for 15 days during the dark phase of the l/d cycle. Sibutramine treatment decreased final body and reproductive organ weights, as well as serum testosterone levels. Sperm transit time through the epididymis was accelerated, and sperm concentration and motility were diminished in the sibutramine-exposed rats. The decrease in sperm concentration was also verified in the epididymal histological sections. In conclusion, the deleterious effects of sibutramine on reproductive parameters of male rats were enhanced when the exposure occurred in the dark phase of the l/d cycle, even after a short exposure duration. Our results reinforce the impact of timing on drug therapeutic action.

RESUMEN

Las mujeres han sido tratadas por décadas con testosterona intentando aliviar una gran variedad de síntomas con riesgos y beneficios inciertos. En la mayoría de los países, la testosterona se prescribe "off-label", de modo que las mujeres están utilizando compuestos y dosis ideadas para tratamientos en hombres. En este sentido, varias sociedades médicas de distintos continentes adoptaron recientemente por consenso una toma de posición sobre los beneficios y potenciales riesgos de la terapia con testosterona en la mujer, explorar las áreas de incertidumbre e identificar prácticas de prescripción con potencial de causar daño. Las recomendaciones con respecto a los beneficios y riesgos de la terapia con testosterona se basan en los resultados de ensayos clínicos controlados con placebo de al menos 12 semanas de duración. A continuación se comentan las recomendaciones. (AU)


There are currently no clear established indications for testosterone replacement therapy for women. Nonetheless, clinicians have been treating women with testosterone to alleviate a variety of symptoms for decades with uncertainty regarding its benefits and risks. In most countries, testosterone therapy is prescribed off-label, which means that women are using testosterone formulations or compounds approved for men with a modified dose for women. Due to these issues, there was a need for a global Consensus Position Statement on testosterone therapy for women based on the available evidence from placebo randomized controlled trials (RCTs). This Position Statement was developed to inform health care professionals about the benefits and potential risks of testosterone therapy intended for women. The aim of the Consensus was to provide clear guidance as to which women might benefit from testosterone therapy; to identify symptoms, signs, and certain conditions for which the evidence does not support the prescription of testosterone; to explore areas of uncertainty, and to identify any prescribing practices that have the potential to cause harm.

RESUMEN

INTRODUCTION: Obesity shows a multifactorial disease and presents a serious public health problem, with an alarming epidemic character. According to NHANES (National Health and Nutrition Examination Survey) from 2015 to 2016, 39.6% of American adults and 18.5% of young people were obese and 7.7% of adults and 5.6% of young people had severe obesity. Brazil ranks fifth in the world ranking, with about 18 million people reaching up to 70 million overweight individuals. Despite shortterm weight loss with diet and exercise, weight regain continues to be a concern. Anti-obesity drugs, such as Sibutramine (SIB), Phentermine (PHEN), Fenproporex (FEN), Mazindol (MAZ), Amfepramone (AMFE) and Orlistat (ORL) may play a role in weight reduction in patients whose condition is refractory to non- and maintenance of weight loss. OBJECTIVE: A systematic review followed by meta-analysis of randomized clinical trials over the past five years to explore the efficacy and safety of anorexigenic drugs for weight reduction and consequent treatment of obesity. METHODS: The search strategy in MEDLINE / Pubmed, Web of Science, ScienceDirect Journals (Elsevier), Scopus (Elsevier), OneFile (Gale) is as follows : - search for mesh terms (Sibutramine, Phentermine, Fenproporex, Mazindol, Amfepramone , Orlistat, Weight loss, Safety), and the use of booleans "and" between mesh terms and "or" among historical findings. RESULTS: It was observed that in the last five years of randomized studies no significant general complications were found, with only 5.7%. The mean overall weight loss was 6.18 (± 2.8) kg in the mean time of 12 months. The overall success rate among these drugs was 80.18%. The p-value values did not present a significant statistical difference, being p <0.05 within each drug group analyzed, for both weight and success rates. CONCLUSION: The scientific findings of randomized studies on the use of anorexigenic drugs to treat obesity have shown safety and efficiency in the last five years, with a reasonable weight loss and no significant complications.

RESUMEN

Amfepramone (AFP) is an appetite-suppressant drug used in the treatment of obesity. Nonetheless, studies on interindividual pharmacokinetic variability and its association with genetic variants are limited. We employed a pharmacokinetic and pharmacogenetic approach to determine possible metabolic phenotypes of AFP and identify genetic markers that could affect the pharmacokinetic variability in a Mexican population. A controlled, randomized, crossover, single-blind, two-treatment, two-period, and two sequence clinical study of AFP (a single 75 mg dose) was conducted in 36 healthy Mexican volunteers who fulfilled the study requirements. Amfepramone plasma levels were measured using high-performance liquid chromatography mass spectrometry. Genotyping was performed using real-time PCR with TaqMan probes. Four AFP metabolizer phenotypes were found in our population: slow, normal, intermediate, and fast. Additionally, two gene polymorphisms, ABCB1-rs1045642 and CYP3A4-rs2242480, had a significant effect on AFP pharmacokinetics (P < 0.05) and were the predictor factors in a log-linear regression model. The ABCB1 and CYP3A4 gene polymorphisms were associated with a fast metabolizer phenotype. These results suggest that metabolism of AFP in the Mexican population is variable. In addition, the genetic variants ABCB1-rs1045642 and CYP3A4-rs2242480 may partially explain the AFP pharmacokinetic variability.

RESUMEN

PURPOSE: Obesity is a chronic clinical condition that is considered one of the most serious health problems in the world because it can cause other chronic metabolic disorders. A meta-analysis was conducted to evaluate the safety and efficacy of 4 central-acting drugs, all approved in Brazil's market for weight loss. METHODS: PubMed, EMBASE, and Cochrane library databases were searched from inception until January 2018 to retrieve randomized controlled trials comparing sibutramine, diethylpropion, mazindol, and fenproporex versus placebo in overweight or obese patients. Language was not a restriction for the database searches. We extracted and combined data from studies that reported adverse drug events and weight change. A random effects meta-analytic model was applied in all calculations. The Cochrane Collaboration tool was used to assess the quality and bias of all included studies. Quality of evidence was assessed by using the Grading of Recommendations, Assessment, Development, and Evaluation criteria. FINDINGS: Fifty-three studies were included, with a total of 16,903 patients with a median follow-up of 12 weeks (2-260 weeks). The appetite suppressants showed a significant weight loss compared with placebo (mean difference [MD], -4.70 kg; 95% CI, -5.25 to -4.15; I2 = 100%; 43 studies). There was an increased total number of adverse events, dry mouth, constipation, insomnia, dizziness, and tachycardia reported in the intervention group (risk ratio [RR], 1.06; 95% CI, 1.01 to 1.10; I2 = 20% [22 studies]; RR, 2.08; 95% CI, 1.76 to 2.47; I2 = 34% [25 studies]; RR, 2.31; 95% CI, 1.88 to 2.84; I2 = 0% [25 studies]; RR, 1.84; 95% CI, 1.40 to 2.39; I2 = 0% [17 studies]; RR, 1.78; 95% CI, 1.24 to 2.58; I2 = 0% [13 studies]; and RR, 2.01; 95% CI, 1.42 to 2.86; I2 = 0% [10 studies], respectively). Sibutramine showed a significant increase in heart rate and mean diastolic pressure compared with placebo (MD, 4.17 beats/min [95% CI, 3.60 to 4.74; I2 = 99%; 23 studies]; MD, 1.68 mm Hg [95% CI, 1.29 to 2.07; I2 = 98%; 22 studies]). IMPLICATIONS: These drugs are effective for weight loss in overweight and obese patients; however, they increase the risk of adverse events. In fact, the evidence is of low quality, the data availability of studied agents (especially for cardiovascular outcomes) are limited, and the studies are of short duration. PROSPERO identifier: CRD42018091083.

RESUMEN

Over the past decades, consume of slimming agents considerably increased in several countries, including Brazil, due to weight-loss and stimulant properties. Since these drugs are controlled to prevent illicit and indiscriminate use, there is a parallel illegal market that uses the Internet and irregular pharmacies in order to distribute these formulations. Slimming agents produced by these illegal sources are known for being manufactured with little or none quality control resulting in uncertain and unknown formulations. For forensic purposes, apprehended pharmaceuticals have to undergo a process of chemical identification that can be difficult due to its complex matrix. In this sense, application of assisted energies in the extraction step such as microwave irradiation can be a promising method to increase the recuperation of the target molecules of the sample. Therefore, the aim of this research was to identify four slimming agents apprehended in Brazil by means of visual inspection, Fourier Transform Infrared Spectroscopy, Differential Scanning Calorimetry and Gas Chromatography - Mass Spectrometry. Moreover, the efficiency of solid-liquid extraction and microwave-assisted extraction was compared. It should be noted that our work was one of the few to use Differential Scanning Calorimetry and the application of microwave irradiation in the analysis of apprehended materials. Results showed that the majority of the samples was counterfeit being composed of one or several adulterants or contaminants. Initially, visual inspection resourcefully screened the slimming agents for possible signs of falsification, however it failed to detect fraudulent products that were very similar to veridical medicines. Sequentially, Fourier Transform Infrared Spectroscopy detected functional groups present in the samples while the presence or absence of the alleged active ingredients were successfully measured with Differential Scanning Calorimetry and, thus, providing a full chemical screening of the apprehended materials. Gas Chromatography- Mass Spectrometry confirmed the presence of adulterants such as caffeine, fluoxetine and phenolphthalein as well as contaminants such as sulfurol in the falsified samples. Finally, comparison of extraction procedures indicated that microwave-assisted extraction increased the recovery of compounds detected in chromatographic analysis to a greater extent than solid-liquid extraction.

RESUMEN

OBJECTIVE: This study evaluated the effect of a protein, the isolated Trypsin Inhibitor (TTI) from Tamarindus indica L. seed, as a CCK secretagogue and its action upon food intake and leptin in obese Wistar rats. METHODS: Three groups of obese rats were fed 10 days one of the following diets: Standard diet (Labina®) + water; High Glycemic Index and Load (HGLI) diet + water or HGLI diet + TTI. Lean animals were fed the standard diet for the 10 days. Food intake, zoometric measurements, plasma CCK, plasma leptin, relative mRNA expression of intestinal CCK-related genes, and expression of the ob gene in subcutaneous adipose tissue were assessed. RESULTS: TTI decreased food intake but did not increase plasma CCK in obese animals. On the other hand, TTI treatment decreased CCK-1R gene expression in obese animals compared with the obese group with no treatment (p = 0.027). Obese animals treated with TTI presented lower plasma leptin than the non-treated obese animals. CONCLUSION: We suggest that TTI by decreasing plasma leptin may improve CCK action, regardless of its increase in plasma from obese rats, since food intake was lowest.

RESUMEN

Preclinical Research & Development Current drugs for obesity treatment have limited efficacy and considerable adverse effects. Combination of drugs with complementary mechanisms of action at lower doses may produce a greater efficacy with a better safety profile. This study was designed to assess the anorectic effect and safety of a diethylpropion + topiramate mixture in rats. The anorectic effect of drugs was measured using a sweetened milk consumption model, and the corresponding interaction was determined by isobolographic analysis, interaction index and confidence intervals. Additionally, blood pressure was measured using a sphygmomanometer in the rat tail. Diethylpropion and topiramate alone or in combination increased the anorectic effect in a dose-dependent fashion in either nondeprived or 12 hr food-deprived rats. All theoretical ED30 values of diethylpropion + topiramate combinations at 1:1, 1:3, and 3:1 dose ratios were significantly higher than experimental ED30 values. In addition, interaction indices and confidence intervals confirmed the potentiation between both drugs. Theoretical ED30 of diethylpropion + topiramate combination did not affect the blood pressure. Data suggests that low doses of the diethylpropion + topiramate combination can potentiate the anorectic effect of individual drugs with a better safety profile, which deserves further investigation in clinical trials.

RESUMEN

Introdução: nos dias atuais, a obesidade tornou-se um problema de saúde pública em escala global. Entre os tratamentos disponíveis, destaca-se o uso da sibutramina. Entretanto, este fármaco apresentou diversos efeitos adversos (EA), sendo os de maior relevância os cardiovasculares. Objetivo: o objetivo deste estudo foi avaliar se a terapia com a sibutramina traz malefícios à saúde humana. Métodos: a revisão sistemática foi realizada seguindo o protocolo PRISMA para revisões sistemáticas e utilizando as bases de dados PubMed, LILACS e SciElo. Nestas, buscaram-se estudos publicados entre 2006 e 2016, utilizando-se dos descritores "sibutramine" e "adverse effects" junto com o operador booleano "AND". Resultados: dezoito artigos, das 479 publicações encontradas, atenderam aos critérios de inclusão, sendo, então, utilizados para compor a presente revisão. Os EA mais encontrados foram complicações cardiocirculatórias (66,6%), sendo as mais frequentes a taquicardia e a hipertensão arterial sistêmica (HAS). Adicionalmente a esses, a constipação intestinal e a boca seca/xerostomia (55,5%), cefaleia e insônia (38,8%) e alterações de humor (26,6%) também foram relatados. Além disso, o tratamento com sibutramina mostrou-se eficaz na perda de peso em 88,88% dos estudos analisados. Conclusão: apesar da terapêutica com sibutramina ter apresentado efetividade na redução de peso, não se pode concluir acerca da segurança desse fármaco.(AU)


Introcuction: in the modern times, obesity has become a global health problem. Sibutramine stands out among the available treatments. However, this drug is associated to several adverse events (AE), being the cardiovascular the most relevant ones. Objetive: the aim of this study was to evaluate whether therapy with sibutramine is harmful to human health. Methods: the systematic review was performed following the PRISMA protocol for systematic reviews and using the databases PubMed, LILACS and SciElo, aiming for studies published between 2006 and 2016. For the search of the papers, the descriptors "sibutramine" and "adverse effects" were used, together with the boolean operator "AND". Results: eighteen studies of 479 publications met the inclusion criteria, and were used in the present review. The main AE founded after the analysis of the articles were cardiocirculatory complications (66.6%), with more frequent tachycardia and systemic arterial hypertension. In addition, intestinal constipation and dry mouth/xerostomia (55.5%), headache and insomnia (38.8%) and mood alteration (26.6%) were also reported. Furthermore, treatment with sibutramine was effective in reducing weight in 88.88% of the studies analyzed. Conclusion: although sibutramine therapy has an effective effect on weight reduction, the safety of the drug is not proved.(AU)

RESUMEN

INTRODUCTION: Different studies have assessed the influence of chewing gum to aid control of appetite and reduce food intake. PURPOSE: The aims of the present study were to evaluate the effects of chewing gum on satiety, food hedonics and snack intake and to explore the potential effects of the combination of Garcinia c ambogia, green coffee extract and L-carnitine on satiety, when administered in a gum format. METHODS: This was a prospective study in which 57 subjects randomly received three kinds of treatments, in a crossover design: (1) active gum; (2) placebo gum; and (3) no gum. Food preferences and appetite sensations were evaluated by means of the Leeds Food Preference Questionnaire and visual analog scales. RESULTS: There was a significant reduction in low-fat sweet snack intake with placebo gum and the active gum compared to no gum and a reduction in high-fat sweet snack intake with the active gum compared to placebo gum and no gum. Total caloric intake was only reduced in the active gum condition. Both the active and placebo gum conditions significantly reduced hunger and prospective food consumption and increased fullness compared to no gum and were associated with a reduced wanting for sweet food in the LFPQ, consistent in a reduction in the relative preference for sweet snacks versus savoury snacks. CONCLUSION: This study supports the notion that chewing gum containing nutraceutical products might aid in the control over snack intake and reduce hunger sensations.

RESUMEN

A adição fraudulenta de ativos farmacêuticos em suplementos nutricionais é um problema mundial. É comum encontrar mensagens sobre perda de peso, aumento da capacidade intelectual e/ou física, e estímulo sexual na embalagem de suplementos adulterados com fármacos sintéticos ocultos em formulações aparentemente inofensivas para os usuários. No Brasil, a disponibilidade de dados sobre a adulteração de suplementos nutricionais é escassa. No presente trabalho, foi desenvolvido e aplicado um método analítico empregando cromatografia gasosa com detector de nitrogênio fósforo (GC-NPD) para a detecção, identificação e quantificação de estimulantes/anorexígenos não declarados nos rótulos de suplementos alimentares, tais como: cafeína, femproporex, anfepramona, fenfluramina, sibutramina, fentermina, efedrina, fenilpropanolamina, pseudoefedrina e 4- metilhexan-2-amina. A técnica de extração/solubilização com metanol foi utilizada, ressaltando a utilização de baixa quantidade de amostra, solvente e padrões de estimulantes. Após o desenvolvimento e validação do método, as análises foram aplicadas em amostras de suplementos nutricionais obtidos em lojas especializadas em suplementos, de diversas partes do estado de São Paulo (n=125). Das 125 amostras de suplemento nutricional analisadas, 38 delas (30%) apresentaram resultado positivo para alguma das substâncias de interesse, dentre elas, sibutramina, cafeína e efedrina mediante a metodologia escolhida. As amostras positivas foram posteriormente analisadas qualitativamente por LC-MS/MS, no propósito de confirmar o resultado positivo obtido. A técnica analítica empregada proporciona seletividade, linearidade, precisão, exatidão, recuperação e limites em conformidade ao objetivo que foram destinadas. Os métodos de preparo de amostra desenvolvidos e validados demonstraram ser simples, práticos, eficientes e diferenciados pelo baixo uso de amostra e solvente


The fraudulent addition of active pharmaceutical compounds in nutritional supplements is, indeed, a worldwide problem. Often, it can be found several advertisements on various supplement packaging assuring weight loss, increased intellectual and/or physical capacity and sexual stimulation. These products may have been 'spiked' with synthetic drugs containing formulations which are apparently harmless to users. In Brazil, the availability of data about adulteration of nutritional supplements is scarce. In the present work, an analytical method using gas chromatography coupled with a nitrogen-phosphorus detector (GC-NPD) was developed and applied for the detection, identification and quantification of undeclared stimulants and/or anorectic agents in food supplement labels, such as: caffeine, fenproporex, amfepramone, fenfluramine, sibutramine, phentermine, ephedrine, phenylpropanolamine, pseudoephedrine e 4- metilhexan -2- amine. The extraction/solubilization with methanol presented satisfactory results, emphasizing the use of low amount of sample, solvent and standards of analytes. After the development and validation, the method was applied in samples of nutritional supplements obtained from specialty stores in various parts of the state of São Paulo (n = 125). From the 125 nutritional supplement samples analyzed, 38 of them (30%) presented positive results for some of the substances of interest, among them sibutramine, caffeine and ephedrine according to the chosen methodology. The positive samples were subsequently analyzed qualitatively by LCMS / MS, in order to confirm the positive result obtained. The analytical technique employed provides selectivity, linearity, precision, accuracy, recovery and limits in accordance with the intended purpose. The sample preparation methods developed and validated to be simple, practical, efficient and differentiated by the low sample and solvent usage

RESUMEN

Os inibidores de apetite são comercializados no Brasil há mais de 30 anos. Em 2010, a Agência Nacional de Vigilância Sanitária (Anvisa) iniciou um processo de revisão da avaliação de risco desses fármacos e cancelou, em 2011, o registro dos três emagrecedores à base de anfetamina (anfepramona, femproporex,mazindol), permitindo que apenas a sibutramina fosse comercializada. A decisão foi revogada em 2014 pelo Congresso Nacional, que autorizou a volta ao mercado brasileiro dos anorexígenos derivados da anfetamina. Este artigo analisa a construção dos sentidos sobre risco por jornais diários durante a cobertura noticiosa da controvérsia relativa aos emagrecedores, nesses dois momentos antagônicos. Com base na semiologia dos discursos sociais, foram analisadas 25 notícias de 2011 e 2014 que demonstraram que o discurso do risco,embora presente na maioria dos textos, foi minimizado pela cobertura política que privilegia os conflitos de interesses, os embates travados com a autoridade sanitária e as contradições do processo.(AU)


Appetite suppressants are sold in Brazil over 30 years. In 2010, the Agência Nacional de Vigilância Sanitária- Anvisa (National Health Surveillance Agency) began a process to review the risk assessment of these drugs and in 2011 cancelled the register of the three amphetamine-based anorexigenics (anfepramone,fenproporex, mazindol), only allowing to be marketed in Brazil the sibutramine. In 2014, the Congressrevoked the decison-making by Anvisa and authorized the sale of the amphetamine derivatives. This paper analyzes how the meanings of risk were built by daily newspapers during the coverage of the appetite suppressants controversy, considering these two antagonistic moments. Based on the social semiotics, weanalyzed 25 newspaper articles published in 2011 and in 2014, which showed that the discourse of risk doesnot assume the center of the discursive scene, resulting in a political coverage that favours the conflicts ofinterests, as well as the disputes with the Anvisa and the contradictions of the process


Los inhibidores del apetito se venden en Brasil hace más de 30 años. En 2010, la Agência Nacional deVigilância Sanitária ­ Anvisa (Agencia Nacional de Vigilancia Sanitaria) inició un proceso de revisión dela evaluación de riesgos de estos fármacos y ha cancelado, en 2011, la inscripción en el registro de los tresinhibidores del apetito de la familia de las anfetaminas (dietilpropión, fenproporex, mazindol), permitiendoque sólo la sibutramina fuese mantenida en el mercado. La decisión ha sido revocada en 2014 por el Congreso Nacional, que autorizó la comercialización de los inhibidores del apetito derivados de la anfetamina.En este artículo se analiza la construcción del sentido del riesgo en periódicos diarios durante la coberturade la controversia relativa a esos fármacos, en los dos momentos antagónicos. Basado en la teoría de losdiscursos sociales, se analizaron 25 noticias de los años 2011 y 2014, que mostraron que el discurso delriesgo ha sido infravalorado por la cobertura política que privilegia los conflictos de intereses, así como lasdisputas con la autoridad sanitaria, y las contradicciones del proceso.

RESUMEN

The aim of this study was to evaluate efficacy and safety of amfepramone, fenproporex and mazindol as a monotherapy for the treatment of obese or overweight patients. A systematic review of primary studies was conducted, followed by a direct meta-analysis (random effect) and mixed treatment comparison. Medline and other databases were searched. Heterogeneity was explored through I2 associated with a p-value. Of 739 identified publications, 25 were included in the meta-analysis. The global evaluation of Cochrane resulted in 19 studies with a high level of bias and six with unclear risk. Due to the lack of information in primary studies, direct meta-analyses were conducted only for amfepramone and mazindol. Compared to placebo, amfepramone resulted in higher weight loss in the short-term (<180 days; mean difference (MD) -1.281 kg; p<0.05; I2: 0.0%; p=0.379) and long-term (≥180 days; MD -6.518 kg; p<0.05; I2: 0.0%; p=0.719). Only studies with long-term follow up reported efficacy in terms of abdominal circumference and 5-10% weight reduction. These results corroborated the finding that the efficacy of amfepramone is greater than that of placebo. Treatment with mazindol showed greater short-term weight loss than that with placebo (MD -1.721 kg; p<0.05; I2: 0.9%; p=0.388). However, metabolic outcomes were poorly described, preventing a meta-analysis. A mixed treatment comparison corroborated the direct meta-analysis. Considering the high level of risk of bias and the absence of important published outcomes for anti-obesity therapy assessments, this study found that the evaluated drugs showed poor evidence of efficacy in the treatment of overweight and obese patients. Robust safety data were not identified to suggest changes in their regulatory status.
