Non-adherence to medication: a challenge for person-centred pharmacotherapy to resolve the problem.

Pharmacotherapy today is claimed to be fascinating, scientific, rational, and objective, very much evidence-based, powerful and fundamental form of treatment for many medical conditions. Non-adherence to medication as an invisible epidemic is argued to be an Achilles' heel of evidence based medicine. Person-centered psychiatry has an important role in helping medicine to better understand human nature, human behavior and patients' choice in complex interactions. Non-adherence is a major target for interventions to improve the quality and outcomes of health care.
