Background: Advent of r-DNA techniques and their application to biology and healthcare system is one of the most exciting eras of scientific history. Objectives: In this review, we discuss about pharmacogenetics, pharmacogenomics, advances, applications, challenges and future perspectives of r-DNA technology. Variability in drug responses is the net result of multiple interacting genes and environmental factors. Conclusion: We found that many technical and conceptual barriers still remain unveil to the world, if the true potential of this field recognize, the genetic disorders will completely disappear and will get a solution for most questionable microbial resistance. It is anticipated that less than 10% of drugs in 10 years from now will be prescribed following a pharmacogenetic test. In future, we need more intensive studies in the areas of pharmacogenomics to identify the targeted gene which is responsible for specific diseases or variable drug response, so the r-DNA technology can easily develop a new drug molecule which can change the gene expression or may modify the targeted gene. Field of pharmacogenomics will lead to new important insights and discoveries that will ultimately lead to the development of new and better drugs and to the rational use of drugs that are already on the market.
