Abstract

Trends in Psychiatry and Psychotherapy Original ArticleResumo Introdução: Existe um padrão imprevisível na prescrição de antipsicóticos e outros medicamentos psicotrópicos para o tratamento da esquizofrenia, especialmente em ambientes com limitação de recursos em países em desenvolvimento. Objetivo: Determinar as prescrições psicotrópicas dadas a pacientes com esquizofrenia em uma clínica ambulatorial de um hospital terciário e descrever as escolhas e tendências dessas prescrições. Métodos: Este foi um estudo descritivo transversal das prescrições dadas a adultos com esquizofrenia. Após consulta clínica, os prontuários dos pacientes foram selecionados aleatoriamente ao longo de um período de 2 anos. Usando um formulário estruturado, os dados foram extraídos dos prontuários, incluindo dados biodemográficos, medicamentos psicotrópicos prescritos e mudanças feitas a essas prescrições. Os dados foram analisados por meio de estatística descritiva. Resultados: Um total de 103 pacientes foram selecionados, com idade média de 35,96±9,78 anos; 48,5% eram do sexo masculino e 51,5% do sexo feminino; 33% estavam desempregados e 38% haviam sido hospitalizados no passado. Houve 231 prescrições iniciais e 228 prescrições atuais, com aproximadamente 2,2 prescrições por paciente. O haloperidol (dose média de 14,77±6,28mg e 11,44±5,55mg para prescrições inicial e atual) e outros antipsicóticos de primeira geração foram os mais comumente prescritos para casos novos (98%). A duração média do uso de psicotrópicos foi de 7,78±5,6 anos. Todos os pacientes receberam prescrição de triexifenidil, e 56,3% dos pacientes tiveram seus medicamentos alterados como resultado de efeitos colaterais. Conclusão: Houve uma alta preferência pelo uso de antipsicóticos de primeira geração para todos os regimes de tratamento (internação e ambulatorial), um padrão que provavelmente persistirá. Descritores: Psicotrópico, prescrição, esquizofrenia, clínica.

“…These results are consistent with the findings in the 2017 study by Oktapaku in Nigeria, which reported that haloperidol was the most widely used antipsychotic among outpatients, and the 2018 study by Khan, which reported that the atypical antipsychotic risperidone was most widely used by patients with schizophrenia. 39,40 The American Psychiatric Association states that the use of different types of antipsychotics depends on the clinical outcome desired. In addition, factors, such as patient response, hospital policy, drug availability, and cost influence the choice of antipsychotics.…”

“…In some parts of the world, there is a higher preference toward the usage of typical antipsychotics, while in other parts of the world, atypical antipsychotics are preferred [ 4 ].
