Pharmacoepidemiology is a sub-discipline of epidemiology which is concerned with evaluating the efficacy, effectiveness and safety of pharmaceutical products while Pharmacoeconomics is branch of health economics which highlight the evaluation of pharmaceutical products in terms of their value for money.
When we observe largely, it seems that the goals of pharmacoepidemiology and pharmacoeconomics are similar of evaluating pharmaceuticals products but on assessing in-depth we find that these streams work in parallel. Practitioners of each discipline work largely in isolation of each other, while the evident logic which seems true in one may also contradict the other.
When we try to figure out the interface between pharmacoepidemiology and pharmacoeconomics we find some interplay which is common in both. They both address the issues related to safety, efficacy and highlight the ratio of risk to benefits of drug therapy. It is seen that pharmacoepidemiology studies will get benefited if suggested policies of health economics are considered, similarly pharmacoeconomics could use the epidemiological research as part of evaluation studies to overcome the concerns such as unbiased estimation.
A fruitful relation between both the streams will definitely allow to enhance a product cycle of pharmaceutical industry which in-turn could result in benefiting the society by making available cost effective products in a shorter time span.
