Management and public health are important domains of competency for pharmacists. In about 90% of Brazilian health departments, pharmacists manage the selection and purchase of medicines. The Pharmaceutical Services and Access to Medicines Management Course (PSAMM) was offered to pharmacists working in the public health system. The aim of this study is to analyze the impacts of the course as perceived by the students (pharmacists). Two thousand five hundred pharmacists completed the course. It is a mixed-methods study, including subscribing forms (n = 2500), evaluation questionnaire (n = 1500), focus groups (n = 10), and semi-structured interviews (n = 31). Participants reported a high level of satisfaction with the course; they considered to have developed competencies related to leadership and management, competencies needed to enhance and sustain their practices in health services. Data analyses showed important barriers to complete the course: high course workload, poor quality of Internet access, lack of support from the health services. Participants highlighted crucial features of the course that helped them develop key competencies: practical in-service activities, useful and realistic contents, tutoring. These features helped participants overcome some important constraints described by them. The educational model described in this study was perceived as having a long-term impact on their behaviors and management practices in health services.
