International Herald Tribune Editorial - Playing down drug risks

It was bad enough when studies showed that the newest and most heavily promoted drugs for treating schizophrenia weren't worth their high cost. Now the disturbing tale of their excessive use has taken a tawdry turn with revelations that Eli Lilly, a pharmaceutical giant, has consistently played down the risks of its best-selling antipsychotic drug, Zyprexa, and has promoted it for unapproved uses.
Hundreds of internal Lilly documents that have surfaced in legal proceedings offer persuasive evidence that the company engaged in questionable behavior to prop up its best- selling drug, which creates almost 30 percent of Lilly's revenue.
Zyprexa belongs to a class of drugs that were billed as a significant advance over the first generation of antipsychotic drugs but turned out to have serious flaws. Zyprexa has a tendency to raise blood sugar and to promote obesity, both of which are risk factors for diabetes. Yet Lilly encouraged its sales representatives to play down these adverse effects when talking to doctors.
The documents also show that Lilly encouraged primary care physicians — far less sophisticated than psychiatrists in treating mental illness — to prescribe the drug for older patients with symptoms of dementia even though it was approved only for schizophrenia and bipolar disorder. It is illegal for companies to promote drugs for unapproved uses, but nearly every major drug company is under investigation for alleged efforts to do so.
Lilly contends that it has never promoted Zyprexa for unapproved uses and has always shown its marketing materials to the Food and Drug Administration, as required by law. Both claims ought to be tested in Congressional hearings that should focus on how well the industry complies with existing laws.
