[Essential medicines and the selection process in management practices of pharmaceutical services in Brazilian states and municipalities].

The selection of medicines is a skilled process that produces an essential medicines list (EML) and substantiates rational management of pharmaceutical services. This paper presents the selection of essential medicines in Brazilian states and municipalities. It discusses the perception of pharmaceutical services managers regarding the concept of essential medicines and strategies adopted for their implementation, in addition to investigating how the National Essential Medicines List was adopted and is supporting local pharmaceutical services actions. A nationwide study was carried out adopting a qualitative methodological approach in health. State and municipal managers from the five Brazilian regions were interviewed. The findings point to weaknesses in local selection procedures and in the use of the National Essential Medicines List (Rename). Barriers such as lack of formalization of pharmaceutical services at regional levels, difficulties in drafting and maintaining a pharmacy and therapeutics committee and the acritical incorporation of drugs on the EML were identified. States and municipalities have distortions that exclude the EML form the concept of essential medicines.
