Cornerstone Therapeutics Inc. (Nasdaq: CRTX) said Monday that is pulling three generic drugs containing the pain killer propoxyphene.

The move came after the Food and Drug Administration requested the withdrawal.

“The move is in response to the Food and Drug Administration’s consultation and subsequent agreement with Xanodyne Pharmaceuticals, Inc. regarding the voluntary market withdrawal of the brand versions of propoxyphene; specifically, Darvon, Darvon-N, and Darvocet-N,” Cornerstone said in a statement.

The affected Cornerstone products:
