Predictive dissolution test

Abstract

Esta dissertação explora o conceito de Real Time Release aplicado à dissolução de comprimidos. O objetivo é propor uma estratégia de controlo de qualidade apropriada alternativa para um medicamento, cuja forma farmacêutica é comprimido revestido por película contendo ibuprofeno ativo, através da análise da guideline ICH Q6A e outros conceitos regulamentares. O ensaio de dissolução é dos testes mais relevantes pela indústria farmacêutica em formas farmacêuticas orais, nomeadamente no controlo de qualidade final dos lotes fabricados. O aumento do conhecimento nesta área e a aplicação de métodos de monitorização mais eficientes são fundamentais para a melhoria do processo de fabrico e do seu controlo. A metodologia envolveu as seguintes etapas: (1) desenvolvimento de análises de risco para identificar os parâmetros que impactam os atributos críticos de qualidade, que constituem ensaios que devem estar dentro de limites apropriados para assegurar a eficácia, qualidade e segurança de um medicamento, do ensaio de dissolução na formulação em estudo; (2) confirmar que os dados apresentam variabilidade suficiente para serem considerados no estudo de avaliação de robustez (3) se considerados suficientes, através de uma análise de robustez, investigar a relação existente entre os fatores identificados no projeto e respetivos perfis de dissolução. Os parâmetros identificados como possivelmente impactantes da cinética de dissolução são: tamanho da partícula de substância ativa, espessura do revestimento, dureza do comprimido e quantidade de substância ativa. Estes parâmetros são monitorizados em rotina, através de testes realizados durante o processo o fabrico, constituindo, assim, uma das abordagens previstas na guideline Real Time Release Testing. Com base nos resultados obtidos, comprovou-se que, para o medicamento em estudo, é viável eliminar o teste de dissolução das especificações do medicamento em estudo. A confirmação da robustez do processo e da formulação do medicamento em estudo asseguram que o perfil de dissolução tem um comportamento previsível e conforme as especificações.

This dissertation explores the concept of Real Time Release applied to the dissolution of tablets. The goal is to propose an alternative appropriate quality control strategy for medicine, whose pharmaceutical formulation is a film-coated tablet containing active ibuprofen, through the analysis of the ICH Q6A guideline and other regulatory concepts. The dissolution test is one of the most relevant tests carried out by the pharmaceutical industry in oral dosage forms, namely in the final quality control of manufactured batches. The increasing knowledge in this area and the application of more efficient monitoring methods are fundamental for the improvement of the manufacturing process and its control. The methodology involved the following steps: (1) development of risk analyses to identify the parameters that impact the critical quality attributes, which consists on those parameters that must be wihtih appropriate limits to ensure the adequate afficacy, quality and safety of a medicine, of the dissolution test in the formulation under study; (2) to evaluate the available data regarding its variability (3) if considered sufficient, through a robustness analysis, to investigate the relationship between the factors identified in the project and the respective dissolution profiles. The parameters identified as possibly impacting the dissolution profile are: active pharmaceutical ingredient particle size, coating thickness, tablet hardness and amount of active pharmaceutical ingredient. These parameters are already monitored in routine, through tests carried out during the manufacturing process, thus constituting one of the approaches considered in the Real Time Release Testing guideline. Based on the results obtained, it was proved that, for medicine under study, it’s feasible to eliminate the dissolution test from the specifications of the medicine under study. Confirmation of the robustness of the process and the formulation of the medicine under study ensures that the dissolution profile has a predictable behaviour and according to specifications.
