The Psychopharmacologists 3 completes a trio of interview-based books about the process of therapeutic innovation in clinical psychiatry. David Healy's method is to interview key individuals involved in the discovery and deployment of drugs that have proved useful to psychiatry, and to draw them together within a model of the mechanism and clinical discovery that he uses as an overall framework. These are historical accounts but highly relevant to the clinical psychiatrist of today, emphasising the importance of research, and of the marketing strategies of pharmaceutical companies in formulating disease entities as well as treatments for them.
