The news follows media reports that major drug distributors McKesson Corp, AmerisourceBergen Corp and Cardinal Health are discussing with governments to settle thousands of opioid-related lawsuits for $18 billion. [nL3N2704B1]

The companies, including Teva, are all defendants in a landmark trial set to begin in federal court in Cleveland, Ohio, on Oct. 21, which will be presided over by U.S. District Judge Dan Polster, who has long pushed for a global settlement of the litigation.

The source also said Johnson & Johnson Inc had offered to pay $4 billion to settle claims related to the U.S. opioid epidemic.

Teva has offered to give away generic drugs, including those that help fight opioid overdose, to resolve all of its cases in an agreement that would run over 10 years, Bloomberg reported on Tuesday.

Teva did not immediately respond to Reuters' request for comment.

If the distributors and Teva settle before the start of the trial, the remaining defendants would be Walgreens Boots Alliance Inc and Henry Schein Inc.
