When we stop at the pharmacy to pick up our Prozac, are we simply buying a drug? Or are we buying into a disease as well? The first complete account of the phenomenon of antidepressants, this authoritative, highly readable book relates how depression, a disease only recently deemed too rare to merit study, has become one of the most common disorders of our day--and a booming business to boot.

The Antidepressant Era chronicles the history of psychopharmacology from its inception with the discovery of chlorpromazine in 1951 to current battles over whether these powerful chemical compounds should replace psychotherapy. An expert in both the history and the science of neurochemistry and psychopharmacology, David Healy offers a close-up perspective on early research and clinical trials, the stumbling and successes that have made Prozac and Zoloft household names. The complex story he tells, against a backdrop of changing ideas about medicine, details the origins of the pharmaceutical industry, the pressures for regulation of drug companies, and the emergence of the idea of a depressive disease. This historical and neurochemical analysis leads to a clear look at what antidepressants reveal about both the workings of the brain and the sociology of drug marketing.

Most arresting is Healy's insight into the marketing of antidepressants and the medicalization of the neuroses. Demonstrating that pharmaceutical companies are as much in the business of selling psychiatric diagnoses as of selling psychotropic drugs, he raises disturbing questions about how much of medical science is governed by financial interest.

David Healy follows his widely praised study, The Antidepressant Era, with an even more ambitious and dramatic story: the discovery and development of antipsychotic medication. Healy argues that the discovery of chlorpromazine (more generally known as Thorazine) is as significant in the history of medicine as the discovery of penicillin, reminding readers of the worldwide prevalence of insanity within living memory.

But Healy tells not of the triumph of science but of a stream of fruitful accidents, of technological discovery leading neuroscientific research, of fierce professional competition and the backlash of the antipsychiatry movement of the 1960s. A chemical treatment was developed for one purpose, and as long as some theoretical rationale could be found, doctors administered it to the insane patients in their care to see if it would help. Sometimes it did, dramatically. Why these treatments worked, Healy argues provocatively, was, and often still is, a mystery. Nonetheless, such discoveries made and unmade academic reputations and inspired intense politicking for the Nobel Prize.

Once pharmaceutical companies recognized the commercial potential of antipsychotic medications, financial as well as clinical pressures drove the development of ever more aggressively marketed medications. With verve and immense learning, Healy tells a story with surprising implications in a book that will become the leading scholarly work on its compelling subject.
