The SPC basic tools have been applied in the process of the tuberculost?ticos drugs encapsulation, primarily concerning the objective to choose, between two speeds, which one is the best one to perform the tuberculostatics encapsulation. Later on, with the company effectively operating, the SPC was applied intending to know the variability of the process and, through the tracking of the process itself, to arrive at an estimated limit for the control of future lots of tuberculostatics of equal dosage. As special causes were detected acting in the process, a cause-and-effect diagram was built in order to try to discover, in each factor that composes the productive process, the possible causes of variation of the capsules average weight. The hypotheses raised will be able to serve as a base for deepened the study to eliminate or reduce these interferences in the process. Also a study on the capacity of the process to attend the specifications was carried out, and this study has shown the process?s inaptitude to take care of them. However, on the side of NUPLAM exists a real yearning to implant the SPC and consequently to improve the existing quality already present on its medicines / Esta disserta??o apresenta um estudo de caso sobre a utiliza??o do Controle Estat?stico do Processo (CEP) no N?cleo de Pesquisas em Alimentos e Medicamentos (NUPLAM). As ferramentas b?sicas do CEP foram aplicadas no processo de encapsulamento de tuberculost?ticos primeiramente com o objetivo de escolher entre duas velocidades qual a melhor para a realiza??o do encapsulamento dos tuberculost?ticos. Posteriormente, com a empresa efetivamente funcionando, o CEP foi aplicado com o intuito de conhecer a variabilidade do processo e atrav?s do monitoramento do mesmo chegar a um limite de controle estimado para o controle de lotes futuros de tuberculost?ticos que possuam a mesma dosagem do tuberculost?tico monitorado. Como foram detectadas causas especiais atuando no processo, um diagrama de causa-e- efeito foi constru?do a fim de tentar descobrir em cada fator que comp?e o processo produtivo as poss?veis causas de varia??o do peso m?dio das c?psulas. As hip?teses levantadas poder?o servir de base para um estudo mais aprofundado para a elimina??o ou redu??o dessas interfer?ncias no processo. Tamb?m foi realizado um estudo sobre a capacidade do processo em atender ?s especifica??es o qual se mostrou incapaz de atend?-las. Contudo, existe por parte do NUPLAM um real anseio em implantar o CEP e conseq?entemente melhorar a qualidade j? existente em seus medicamentos
