Research sheds light on potential biological mechanisms that impact adherence to medications

How strictly patients follow a prescribed drug treatment (drug adherence) is clearly important if the therapy is to have maximum effect. A number of things can affect adherence, including behavioral and socioeconomic factors, but to date there have been few investigations into the role played by genetics. Now, research to be presented at the annual conference of the European Society of Human Genetics today has thrown new light on the potential biological mechanisms that can affect adherence to treatment.
