Item: Angell, quoting, among others, Tufts University psychiatrist Dr. Daniel Carlat, attacks the widely held belief that depression and other mental disorders result from chemical imbalances in the brain.
Item: Citing the research of British psychologist Irving Kirsch, Angell writes that some of the most widely used antidepressants, including Prozac, Paxil, Zoloft, Celexa, and Effexor, performed only marginally better than placebos in Food and Drug Administration tests, a “clinically meaningless’’ result.
Item: Angell uses a book by journalist Robert Whitaker to suggest that newly minted antipsychotic drugs may be causing “an epidemic of brain dysfunction.’’
A few days after Angell’s essay appeared, Kramer published a lengthy essay, “In Defense of Antidepressants’’ in The New York Times. His key point: “Antidepressants work - ordinarily well, on a par with other medications doctors prescribe.’’ Kramer attacked Kirsch’s analysis of FDA drug trials, allowing that they can be “quick’’ and “sloppy,’’ and adding that the kinds of people who present themselves for drug research studies “are likely to be an odd bunch.’’
More convincingly, Kramer cited drug companies’ “maintenance studies,’’ in which patients successfully taking antidepressants switched to dummy pills. “If the drugs are acting as placebos,’’ Kramer wrote, “switching should do nothing.’’ But the drugs significantly reduced the odds of relapse. “These results, rarely referenced in the antidepressant-as-placebo literature, hardly suggest that the usefulness of the drugs is all in patients’ heads,’’ Kramer concluded.
What prompted Kramer to defend antidepressants? “I had never really come out and said that antidepressants work in ordinary ways for ordinary diseases,’’ he said. “Doctors work with these tools all the time. It’s true that these medications are imperfect, and we would all like them to be better, but we’ve all seen them work. You would have to start from a really suspicious stance to think that the whole enterprise is corrupt.’’
