Pharmacogenomic discoveries may effectively assist clinicians and healthcare providers in determining the right drugs
and proper dose for each patient, which can help avoid side effects or adverse reactions, and
improve the drug therapy. Currently, pharmacogenomic approaches have proven their utility when
it comes to the use of cardiovascular drugs, antineoplastic drugs, aromatase inhibitors, and agents
used for infectious diseases. The rapid innovation in sequencing technology and genome-wide
association studies has led to the development of numerous data resources and dramatically chan-
ged the landscape of pharmacogenomic research. Here we describe some of these web resources
along with their names, web links, main contents, and our ratings.
