Social pharmacy examines pharmacy practice through social scientific and humanistic perspectives rather than just natural sciences. It studies how social factors like beliefs, attitudes, relationships and processes influence medicine use. Topics in social pharmacy include pharmacist performance, inter-professional relationships in drug therapy, consumer medication choices, predicting noncompliance, explaining noncompliant behavior, and outcomes of pharmaceutical care from economic and humanistic views. Social pharmacy supplements pharmacy's traditional natural science foundations with knowledge from disciplines studying people and systems.
