PITTSBURGH (AP) -- Generic drug giant Mylan Inc. is suing the Pittsburgh Post-Gazette for defamation over a story based on internal documents that prompted a Food and Drug Administration review.

The suit, filed Friday in the Circuit Court of Monongalia County, W.Va., says the paper omitted and distorted facts in a July article that said employees at Mylan's Morgantown facility ignored warnings about manufacturing problems.

In August, the FDA concluded Mylan did nothing wrong. Mylan is based in Canonsburg, Pa., a Pittsburgh suburb.

The Wall Street Journal reports that, in the lawsuit, Mylan claims the article led to stock fluctuations and damaged its reputation.

The paper declined to comment.

Mylan also sued the paper in August alleging misappropriation of trade secrets.
