Antidepressants: Best for Severe Depression?
New Analysis Finds 2 Antidepressants Offer Little Benefit for Less Severe Depression
The study results are no surprise to Peter Galier, MD, an internal medicine
specialist and former chief of staff at Santa Monica--UCLA Medical Center &
Orthopaedic Hospital, Santa Monica, Calif.
''Much like any other disease process, the more severe the disease or
symptoms, the more improvement with treatment," he says.
But the analysis doesn't give a complete picture of the effects of
antidepressants, says Gregory Asnis, MD, a professor of psychiatry at Albert
Einstein College of Medicine and director of the anxiety and depression clinic
at Montefiore Medical Center in New York, who reviewed the analysis for
"The data is unfortunately skewed to two medications, only one of which
[Paxil] is still commonly used," Asnis says.
And Paxil, he finds, can have more side effects, such as sedation and sexual
problems, than some of the other SSRI drugs.
The finding of greater differences between placebo and medication in only
the severely depressed was not a surprise to him, either, he says. However, he
says, the studies were short-term (6 to 11 weeks) and the benefit of the
medication could have kicked in later.
''The study contributes to the extensive research that has helped to
characterize the role of antidepressants over the years," says Sarah Alspach, a
spokeswoman for GlaxoSmithKline, which makes Paxil. "Since its approval by the
FDA in 1992, Paxil has helped millions of people battling mental illness lead
more productive, happier lives. Antidepressants are an important option, in
addition to counseling and lifestyle changes, for treatment of depression."
A spokesperson for Eli Lilly, which makes the antidepressant Prozac,
declined comment on the new analysis.
In an email, Alan Goldhammer, vice president of scientific and regulatory
affairs for the Pharmaceutical Research and Manufacturers of America (PhRMA),
says, "This is a matter best addressed by companies whose drugs were studied
and the individual physicians who are tasked with making treatment decisions
based on which therapies are best suited for treating their patients."
