More Trouble for Zyprexa

In what is becoming more and more common, Eli Lilly’s Schizophrenia drug Zyprexa has run into a little more trouble.  From the Reuters, via the Indianapolis Star:

Excessive sedation is a “serious safety concern” with an experimental, long-acting form of Eli Lilly and Co.’s blockbuster Zyprexa schizophrenia medicine, U.S. drug reviewers said in an analysis released Monday.

Food and Drug Administration staff said the injectable formulation, called Zyprexa Adhera, was shown to be effective for acute and long-term treatment of schizophrenia, Reuters and Bloomberg both reported.

But risks include excessive sleepiness.

The analysis was released ahead of a meeting by a panel of outside advisers who will evaluate the drug Wednesday.”Excessive sedation events are a serious safety concern because of the severity of excessive sedation, the unpredictable characteristics, and relatively high incidence – 0.07% of injections and 1.3% of patients,” FDA staff said.

Lilly officials, in a separate summary, said they thought the benefits of the long-acting formulation outweighed the risks.

“Although there are important additional safety considerations associated with the injection, they are manageable with appropriate labeling and risk-minimization activities,” the company said, Reuters reported.
