This text 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 using clinical discovery as the overall theme of his interviews. The accounts are historical, but are highly relevant to contemporary clinical psychiatrists, and they emphasize the importance of research and of the marketing strategies of pharmaceutical companies in formulating disease entities as well as treatments for them. The unifying theme of this third text is the role of receptors, and it includes coverage of international developments, including France, Eastern Europe and Japan. There is also a chapter on paediatric psychopharmacology.
