A medical journal has apologised to a drugs firm after reporting confidential papers on anti-depressant drug Prozac went missing during a murder case.
Prozac is used to treat depression
The British Medical Journal issued the retraction over the January 1 article.
The journal said it now accepted the papers were disclosed by Prozac makers Eli Lilly in a lawsuit on the shooting of eight people by Joseph Wesbecker.
In the New Year article, the BMJ said it had handed the papers on clinical trials to the US drug regulator.
The BMJ statement said it had conducted a detailed investigation after a complaint by Eli Lilly.
"The investigation has revealed that all of the documents supplied to the BMJ that were either Eli Lilly documents or were in the hands of Eli Lilly had in fact been disclosed during the suit.
"The BMJ did not intend to suggest that Eli Lilly caused these documents to go missing.
"As a result of the investigation, it is clear that these documents did not go missing.
"The BMJ accepts that Eli Lilly acted properly in relation to the disclosure of these documents in these claims.
"The BMJ is happy to set the record straight and to apologize to Eli Lilly for this statement, which we now retract, but which we published in good faith."
Eli Lilly president Sidney Taurel said: "We accept the apology and retraction with the understanding that both our organisations are committed to providing doctors and patients with accurate information about medications."
