The science of pharmacoeconomics and pharmaceutical policy, although not new, is continually developing. In recent years most drug administration bodies of the developed and developing countries have tried to make their decisions on the basis of scientifically sound, cost-effective evidence. There have been several developments in the procedures to have better drug policies based on new economics and cost-effectiveness models. This progress necessitates more studies and evidence from various countries. This cross-journal series in DARU Journal of Pharmaceutical Sciences and Journal of Pharmaceutical Policy and Practice will disseminate new ideas, methods, and findings of applied pharmacoeconomics in implementation of pharmaceutical policies.
