clinical drug product A drug product that is bearer of a clinical drug role. We changed the label to 'clinical drug product' because it was clear that the part of the definition re: bearer of a "clinical drug role" made it such. Other drugs don't have clinical drug roles, especially illicit ones. Therefore we changed the label here, as well as the subClassOf. Now it is subClassOf "drug product", which also required changing the definition here. William Hogan drug product
