PROGRESSING BACKWARDS:
In Antipsychotics, Newer Isn't Better: Drug Find Shocks Researchers (Shankar Vedantam, 10/03/06, Washington Post)
Schizophrenia patients do as well, or perhaps even better, on older psychiatric drugs compared with newer and far costlier medications, according to a study published yesterday that overturns conventional wisdom about antipsychotic drugs, which cost the United States $10 billion a year.The results are causing consternation. The researchers who conducted the trial were so certain they would find exactly the opposite that they went back to make sure the research data had not been recorded backward. [...]
Especially over the past decade, older antipsychotics such as Haldol have been widely criticized for triggering uncontrolled body movements, even as the new "atypical" antipsychotics were hailed for causing fewer side effects. Recently, however, concern has grown that antipsychotics in general, and some of the newer drugs in particular, may be causing metabolic side effects.
The new study randomly assigned 227 schizophrenia patients to two groups -- one received a newer antipsychotic, the other an older drug. The patients were evaluated for more than a year by experts who did not know which drug was being taken.
While the researchers had expected a difference of five points on a quality-of-life scale -- showing the newer drugs were better -- the study found that patients' quality of life was slightly better when they took the older drugs. Jones said a conservative interpretation of the data suggested that there is no difference, "so the notion you would pay 10 times as much would be difficult to justify."
"Why were we so convinced?" he asked, referring to the widespread opinion among psychiatrists that the new drugs were worth the great difference in cost. "I think pharmaceutical companies did a great job in selling their products. That is certainly one issue.
"It became almost a moral issue on whether you would prescribe these dirty old drugs," he added. "It became the 'my son' phenomenon. What would you prescribe for your son?"

Thank you for reporting this triumph of science. Too bad no one listens to scientists.
