This study aims to evaluate the criteria and procedures for the selection of antidiabetic and
antihypertensive drugs purchased by the public health network of the cities in the Ourinhos Micro-region,
Sao Paulo, Brazil. A cross-sectional, multi-center, exploratory, quantitative study was developed in the 12
cities that constitute the Ourinhos Micro-region. The data obtained showed that cities standardize and
purchase a large number and diverse range of pharmaceutical specialties, including several drugs that are
not included in the 2008 National List of Essential Drugs (Rename), administrative rule No. 3237 issued on
December 24, 2007 and the list of drugs of Dose Certa, a medication program by the Sao Paulo State Government.
A large variation between costs of interchangeable drug was observed. In conclusion, pharmacoeconomic
research in the selection process of drugs, in combination with interventions involving prescribers
and Judiciary Power will reduce public spending allocated to medication purchase.
