Pfizer disputes claim Zoloft doesn't work

TRENTON, N.J. -- The maker of Zoloft is being sued in an unusual case alleging the popular antidepressant has no more benefit than a dummy pill and that patients who took it should be reimbursed for their costs.
Zoloft's maker, Pfizer Inc., the world's biggest drugmaker by revenue, disputes the claim, telling The Associated Press Thursday that clinical studies and the experience of millions of patients and their doctors over two decades prove Zoloft is effective.
The lawsuit was described as frivolous by Pfizer and four psychiatry experts interviewed by The AP.
Not so, according to plaintiff Laura A. Plumlee, who says Zoloft didn't help her during three years of treatment. Her attorney, R. Brent Wisner of the Los Angeles firm Baum Hedlund Aristei Goldman, argues the Food and Drug Administration shouldn't have approved Zoloft because Pfizer didn't publish some clinical studies that found the drug about as effective as a placebo.
"It's about Pfizer deliberately withholding this information from consumers and then advertising this drug as very effective," Wisner said.
The suit accuses Pfizer of consumer fraud and other offenses, including quietly paying prominent doctors to tout Zoloft to colleagues or to be listed as authors of positive medical journal articles the company prepared for publication. New York-based Pfizer did not specifically respond to those allegations.
"Pfizer believes the lawsuit filed in California is groundless and is based largely on information ... that has been widely criticized by many experts in the mental health field," the company said in a statement provided to The AP.
It said the FDA approved Zoloft in 1991 after reviewing "efficacy and safety data from more than 20 clinical studies involving more than 5,000 patients."
The president-elect of the American Psychiatric Association, Dr. Jeffrey Lieberman, said the lawsuit's claims are "ridiculous" and without merit.
