Uma abordagem atual da utilização de antidepressivos no manejo da depressão pós-parto / A current approach to the use of antidepressants in the management of postpartum depression / Enfoque actual de la utilización de antidepresivos en el manejo de la depresión postparto

OBJETIVO: caracterizar a utilização de antidepressivos no manejo da depressão pós-parto. MÉTODO: empregou-se uma revisão integrativa de literatura, das bases de dados PubMed e Biblioteca Virtual em Saúde, com aplicação de descritores, visando responder a pergunta norteadora do trabalho, entre os dias 25 de fevereiro e 10 de março de 2019. Com base nos critérios de inclusão e exclusão, foram selecionados 23 artigos que, posteriormente, foram submetidos à categorização. RESULTADOS: a sertralina deve ser a droga de escolha para o tratamento farmacológico da depressão puerperal. Constatou-se também, que a utilização profilática de antidepressivos em mulheres susceptíveis é contestável e pouco se sabe sobre os possíveis efeitos colaterais. Ademais, foi encontrado que não há consenso sobre a superioridade da terapia farmacológica em detrimento às psicoterapias. CONCLUSÃO: há evidencias que fundamentam o uso de sertralina, paroxetina, duloxetina, nortriptilina e imipramina para tratar mulheres com depressão pós-parto, sendo a amamentação sempre recomendada. Ressalta-se que emerge a necessidade de estudos com amostras representativas para validar ou restringir o uso de psicofármacos na profilaxia da depressão puerperal.

OBJECTIVE: this study aimed to characterize the use of antidepressants in the management of postpartum depression. METHOD: an integrative literature review of the PubMed and Virtual Health Library databases was used, with the application of descriptors, aiming to answer the guiding question of the work, between February 25th and March 10th, 2019. Based on the inclusion and exclusion criteria, 23 articles were selected that were later submitted to categorization. RESULTS: sertraline should be the drug of choice for the pharmacological treatment of puerperal depression. It was also found that the prophylactic use of antidepressants in susceptible women is controversial and little is known about the possible side effects. In addition, it was found that there is no consensus on the superiority of pharmacological therapy to the detriment of psychotherapies. CONCLUSION: there is evidence supporting the use of sertraline, paroxetine, duloxetine, nortriptyline and imipramine to treat women with postpartum depression, and breastfeeding is always recommended. It is worth noting that the need for studies with representative samples to validate or restrict the use of psychotropic drugs in the prophylaxis of puerperal depression emerges.

Amitriptyline, clomipramine, and maprotiline attenuate the inflammatory response by inhibiting neutrophil migration and mast cell degranulation

Objective: Despite the recognized anti-inflammatory potential of heterocyclic antidepressants, the mechanisms concerning their modulating effects are not completely known. Thus, we evaluated the anti-inflammatory effect of amitriptyline, clomipramine, and maprotiline and the possible modulating properties of these drugs on neutrophil migration and mast cell degranulation. Methods: The hind paw edema and air-pouch models of inflammation were used. Male Wistar rats were treated with saline, amitriptyline, clomipramine or maprotiline (10, 30, or 90 mg/kg, per os [p.o.]) 1 h before the injection of carrageenan (300 μg/0.1 mL/paw) or dextran (500 μg/0.1 mL/paw). Then, edema formation was measured hourly. Neutrophil migration to carrageenan (500 μg/pouch) and N-formyl-methionyl-leucyl-phenylalanine (fMLP) (10-6 M/mL/pouch) was also investigated in 6-day-old air-pouch cavities. Compound 48/80-induced mast cell degranulation was assessed in the mesenteric tissues of antidepressant-treated rats. Results: All tested antidepressants prevented both carrageenan- and dextran-induced edema. The anti-inflammatory effect of these drugs partially depends on the modulation of neutrophil migration, since they significantly counteracted the chemotactic response of both carrageenan and fMLP (p < 0.01). Furthermore, amitriptyline, clomipramine and maprotiline inhibited compound 48/80-induced mast cell degranulation (p < 0.001). Conclusions: These results suggest an important anti-inflammatory role of heterocyclic antidepressants, which is dependent on the modulation of neutrophil migration and mast cell stabilization. .

Riesgo de suicidio en población pediátrica tratada con antidepresivos: impacto de la alerta de 2003 en la prescripción e investigación en eficacia y seguridad / Suicide risk in pediatric populations treated with antidepressives: impact of the 2003 alert in prescription and research in efficacy and safety

Objective: To analyze the use and research in efficacy and safety of antidepressants in Mayor Depressive Disorder (MDD) in paediatric population after the 2003 international warning from regulatory agencies (EMA, FDA) about an increased suicide risk in children and adolescents treated with antidepressants. Method: A review of the last 10 years publications regarding the prescription trends and efficacy and safety of antidepressants in paediatric depression was carried out. Cochrane and Pub Med databases were used. Results: Since the alert there has been a change in previous ascending trends of antidepressant prescription to children and adolescents with a decrease in their use, as well as an increase in the completed suicide rate in this population. Clinical management and monitoring of these patients have been slightly modified. Since 2004, two studies (escitalopram, citalopram) showed significant efficacy vs placebo for paediatric depression, adding more evidence to previous Fluoxetine results. Three studies show significant efficacy in adolescent MDD but only one with sertraline was designed to detect subgroup age differences. No more evidence of increased suicide risk has been found. Conclusions: Safety warnings from regulatory agencies EMA and FDA about antidepressant use in paediatric population has modified sligthtly clinical practice, with a decreased trend in prescription. More research has been conducted since 2004, adding evidence for efficacy but not for an increased risk of suicide. Methodological flaws of conducted studies after the warnings remain similar to previous research.

Objetivos: Analizar el uso de antidepresivos (AD) y la investigación sobre su eficacia y seguridad en población pediátrica con Trastorno Depresivo Mayor (TDM), tras la alerta de las agencias reguladoras European Medicines Agency (EMA) y la americana Food and Drugs Administration (FDA) en 2003 sobre el riesgo de suicidio en menores de 18 años tratados con antidepresivos. Métodos: Se han revisado las publicaciones en los últimos 10 años sobre eficacia y seguridad de los antidepresivos en menores de 18 años, y sobre las prácticas de prescripción de estos fármacos en esta población. Se utilizaron las bases de datos Cochrane y Pub Med. Resultados: Desde la Alerta se ha producido un cambio en la tendencia previa ascendente en la prescripción de antidepresivos a niños y adolescentes, así como un incremento de las tasas de suicidio en esta población. La monitorización de estos pacientes se ha modificado ligeramente. Desde 2004, dos ensayos clínicos (1 citalopram, 1 escitalopram) han obtenido significación estadística en eficacia frente a placebo en niños y adolescentes, sumándose a la evidencia previa para fluoxetina. Tres estudios demuestran eficacia en adolescentes pero sólo uno con sertralina fue diseñado para evaluar separadamente los grupos de edad. No se han encontrado estudios que añadan evidencia sobre el incremento del riesgo de suicidio. Conclusiones: La advertencia de las agencias reguladoras (EMA y FDA) ha modificado levemente la práctica clínica de los profesionales. Se han publicado estudios desde 2004, que aportan nuevos resultados de eficacia pero no más evidencia respecto a su seguridad.

Effectiveness of cognitive-behavioral therapy and amitriptyline in patients with chronic temporomandibular disorders: a pilot study

The aim of this pilot study was to evaluate the effectiveness of cognitive-behavioral therapy (CBT) and use of amitriptyline, a tricyclic antidepressant, in patients with chronic temporomandibular disorders (TMD). Forty-seven women (mean age = 35.4 years old) with chronic TMD were enrolled in the study and divided into 4 groups: amitriptyline; amitriptyline and CBT; placebo and CBT; and placebo only (control). Patients were managed for 7 consecutive weeks. Follow-up evaluations were done at the 1st, 7th and 11th weeks of treatment. The presence and severity of pain, levels of depression, and quality of life and sleep were measured. Data were analyzed using ANOVA, Chi-square and Cochran tests, considering a significance level of 5 percent. Improvements were found for all factors considered in the intragroup analysis, although no significant differences were detected among groups. However, at the end of the treatment (11 weeks of follow-up), these positive outcomes persisted only for the women treated with amitriptyline and CBT. The obtained results suggest that the combination of amitriptyline and CBT may be effective in reducing pain and depression levels as well as in improving the quality of life and sleep in patients with chronic TMD.

O objetivo deste estudo piloto foi avaliar a eficácia do uso de uma terapia cognitivo comportamental (TCC) e da amitriptilina, um antidepressivo tricíclico, no tratamento de pacientes portadores de disfunções temporomandibulares (DTM) crônicas. Quarenta e sete mulheres (com 35,4 anos em média) diagnosticadas com DTM crônica foram selecionadas e divididas em 4 grupos: amitriptilina; amitriptilina + TCC; placebo + TCC; e placebo (controle) e controle. As pacientes foram submetidas às terapias por 7 semanas consecutivas. As reavaliações aconteceram 1, 7 e 11 semanas após o início da terapia (11 semanas de avaliações). Foram avaliados a presença e severidade de dor, o nível de depressão, a qualidade de vida e do sono. Os dados foram avaliados através de ANOVA, Qui-quadrado e teste de Cochran, considerando um nível de significância de 5 por cento. Foram observadas melhoras significantes em todos os fatores avaliados para todos os grupos, porém não foram observadas diferenças entre os grupos. Após o final da terapia, os resultados positivos persistiram apenas para o grupo amitriptilina + TCC. Os resultados sugerem que o uso associado de amitriptilina e TCC no tratamento de pacientes portadores de DTM crônicas pode ser efetivo na melhora da dor, nível de depressão, qualidade de vida e do sono.

Pharmacoeconomics of antidepressants in moderate-to-severe depressive disorder in Colombia / Farmacoeconomía de antidepresivos en trastornos de depresión moderada e intensa en Colombia

OBJECTIVE: To compare three antidepressant drugs from different classes used in treating moderate-to-severe major depressive disorder (MDD) in Colombian adults. METHODS: Based on expert input, a decision-tree model was adapted for Colombia to analyze data over 6 months from the government-payer perspective. The cost-effectiveness of amitriptyline, fluoxetine, and venlafaxine was determined. The clinical outcome was remission of depression (a score <7 on the Hamilton Depression [HAM-D] scale or <12 on the Montgomery-Åsberg Depression Rating Scale [MADRS]) after 8 weeks of treatment. Clinical data were obtained from the literature and costs from standard Colombian price lists. One-way and multivariate sensitivity analyses tested model robustness. RESULTS: Costs per patient (in 2007 US$) for treatment were: venlafaxine, $1 618; fluoxetine, $1 207; and amitriptyline, $1 068. Overall remission rates were 73.1 percent, 64.1 percent, and 71.3 percent, respectively. Amitriptyline dominated fluoxetine (i.e., it had lower costs and higher outcomes). The incremental cost-effectiveness ratio (ICER) of venlafaxine over amitriptyline was US$ 31 595. The acquisition price of venlafaxine was the model's cost driver, comprising 53.4 percent of the total cost/patient treated, compared with 18.5 percent and 24.8 percent for fluoxetine and amitriptyline, respectively. For the others, hospitalization comprised the major cost (72.1 percent and 65.2 percent, respectively). Probabilistic (Monte Carlo) sensitivity analysis confirmed the original findings of the pharmacoeconomic model. CONCLUSIONS: Amitriptyline is cost-effective in comparison to fluoxetine and venlafaxine in Colombia. However, the cost of venlafaxine was estimated for the brand-name product, as generics were not currently available. These cost-effectiveness results can be substantially affected by the presence of generics or drug cost regulations.

OBJETIVO: Comparar tres medicamentos antidepresivos de diferentes clases empleados para tratar trastornos depresivos mayores moderados e intensos en adultos colombianos. MÉTODOS: A partir de los aportes de expertos se adaptó un modelo de árbol de decisión para Colombia a fin de analizar los datos de seis meses desde la perspectiva del gobierno como pagador de los servicios. Se determinó la relación costo-efectividad de la amitriptilina, la fluoxetina y la venlafaxina. El desenlace clínico fue la remisión de la depresión (una puntuación <7 en la escala de depresión de Hamilton o <12 en la escala de valoración de la depresión de Montgomery-Åsberg) después de 8 semanas de tratamiento. Los datos clínicos se obtuvieron de la literatura especializada y los costos, de las listas habituales de precios de Colombia. Se realizaron análisis de sensibilidad simples y multifactoriales para probar la robustez de los modelos. RESULTADOS: Los costos del tratamiento por paciente (en dólares estadounidenses de 2007) fueron: US$ 1 618 para la venlafaxina, US$ 1 207 para la fluoxetina y US$ 1 068 para la amitriptilina. Las tasas de remisión general fueron 73,1 por ciento, 64,1 por ciento y 71,3 por ciento, respectivamente. La amitriptilina tuvo un menor costo y una mayor remisión que la fluoxetina. La razón de rentabilidad incremental de la venlafaxina sobre la amitriptilina fue de US$ 31 595. El inductor de costos (cost driver) del modelo fue el valor de adquisición de la venlafaxina, que representó 53,4 por ciento del total del costo por paciente tratado, en comparación con la fluoxetina (18,5 por ciento) y la amitriptilina (24,8 por ciento). En los otros casos, la hospitalización representó el mayor costo (72,1 por ciento y 65,2 por ciento, respectivamente). El análisis de sensibilidad probabilístico (Monte Carlo) confirmó los resultados preliminares del modelo farmacoeconómico. CONCLUSIONES: En Colombia, la amitriptilina es más efectiva en función del...

Antidepressivos e alterações no peso corporal / Effects of antidepressant medications on body weight

A depressão é uma doença que pode levar a mudanças no peso, influenciadas por fatores específicos da doença, como alterações no apetite e na atividade física, ou pelos antidepressivos. Este artigo objetiva analisar os estudos que descrevem os efeitos dos antidepressivos em alterações do peso corporal. Realizou-se uma pesquisa nas bases de dados Medline, Lilacs e Cochrane, utilizando as palavras chaves " antidepressivo" e " peso" . Foram selecionados os estudos que analisaram o tema em pacientes depressivos, priorizando-se aqueles relacionados às drogas mais utilizadas nos serviços de saúde no Brasil. A análise dos estudos indicou que a mudança de peso atribuída ao tratamento com antidepressivos apresenta resultados ainda controversos, sendo influenciada por fatores como o tempo de uso e a dosagem do medicamento, estudos com poder limitado, entre outros. Assim, estudos com maior poder, tendo como foco a ação das drogas antidepressivas nas alterações do peso corporal em pacientes depressivos, ainda são necessários.

Depression is a disorder that may affect patient's weight because of specific factors of the disease, such as changes in appetite and in the level of physical activity, as well as because of the use of antidepressant medications. The objectives of this paper are to analyze studies that discuss the effect of antidepressant medications on the patients' weight. Medline, Lilacs and Cochrane databases were searched for relevant studies using the words 'antidepressant' and 'weight'. Publications regarding antidepressant drugs commonly used in health services in Brazil and their effects on body weight in depressive patients were selected. The studies indicated that weight changes related to antidepressant therapies are still controversial, influenced by factors such as length and dosage of antidepressant use, limited power of the studies, among others. Thus, more powerful studies focusing on how antidepressant medications affect weight in depressive patients are still needed.
