This thesis aimed to understand pharmaceutical services regarding the responsibilities shared by Federal, State and Local Governments, based on Unified Health System (SUS) legal framework. It is a descriptive research, with qualitative approach. First, the construction and validation of a logical framework of pharmaceutical services in SUS was carried out. The logical framework was based on the elements of the evaluation model of pharmaceutical services proposed by Cosendey, Hartz and Bermudez (2003), interfederative responsibilities expressed in official documents and literature related to pharmaceutical services. For its validation, seven specialists were consulted, using Delphi method as a consensus technique. The logical framework of pharmaceutical services in SUS was composed by eight components (selection, financing, programming and acquisition, logistics, use, management, education and research), its objectives, and by an array of 54 responsibilities and 73 products that support the three expected outcomes of pharmaceutical services in SUS: access to essential medicines, rational use of medicines and structuring of pharmaceutical services. Then, it was held the characterization of pharmaceutical services in São Paulo State, according to health responsibilities and expected products of state government, described in the logical framework. The definition of the aspects considered in this process was based on bibliographic research. Documents obtained from different sources were organized and critically analyzed. There were advances and challenges of pharmaceutical services in São Paulo State: the share of medicines in health spending, the counterpart for basic care and fund-to-fund transfers to municipalities were higher than national parameters; on average, there was 83.5% availability and 59.5 days/year of drug shortages in the "Farmácias de Medicamentos Especializados", which served 3.09% of the population; the State Drug Policy was instituted in 2006 and there was integration of pharmaceutical services in management instruments; the need to reorient selection of medicines and the promotion of rational use, integration to social control and greater investment in monitoring / evaluation, training and research were identified. In conclusion, the logical framework of pharmaceutical services in SUS allows an understanding of the role of SUS managers in a comprehensive way, serving as a reference for the definition of strategies to implement and operationalize pharmaceutical services in health care networks, as well as for the construction of theoretical evaluation models of pharmaceutical services as shared responsibility within SUS.
