As a conclusion of this analysis, it can be stated that pharmacoeconomic evaluation contributes to give a more effective and efficient use to drugs used in the treatment of different diseases. Within the national context of sanitary system, pharmacoeconomics allows to assemble, in a cohesion way, the pharmaceutical industry's interests with those of health-services offering.
