Pharmacoeconomic studies evaluate the cost and effects of medicinal products and serve as a guidance tool for optimal healthcare resource allocation.

Depending on the question that is to be answered, a pharmacoeconomic study may be based on cost-minimization analysis, cost-benefit analysis, cost-effectiveness analysis or cost-utility analysis or cost-per-QALY (Quality-adjusted life years) analysis.

The more expensive a drug may be, the more imperative is the need for a pharmacoeconomic study that will help achieve maximum improvement in quality of life with minimum costs.
