In hospital organizations there is a wide variety of products and there is a commitment not to allow the losses and the operational failure (Portela, 2001). One way to avoid these losses is the rational use of medicines through standardization (Klügl et al, 1999). Thus you can create value to the patient so that the pharmacy handling the products properly offering quality services (Barbieri and Machline, 2006). In this scenario, the management of the health costs organizations have strategic role. Medicines represent a significant portion of these costs and their internal logistics, complex and with many details, should work in the best possible way. This is because the processes, in which they are involved, are fundamental parts to the quality of care both prized by hospitals. This study aims to investigate and analyze the current situation of two processes, unitarization and the dispensation that directly affect the pharmacy, observing the practices adopted in the hospital segment. For this, he was made an analysis of hospital pharmacies and flows of both processes in order to understand them better. Then studied in a real case, diagnosing the points of improvement of the operation. Thus, we could come up with some solutions that were designed to optimize the processes studied for improvement points raised and prove the hypothesis that the stock of centralization can be applied, with necessary adaptations respecting the individual, to hospitals.
