U.S. Regulators approved the first generic rival to johnson & johnson's duragesic pain relief skin patch. Mylan laboratories inc. Will produce several different strengths of the patch, known generically as the fentanyl transdermal system, and launch the product immediately. Johnson & johnson's annual sales of the patch total about $1.63 billion.
Mylan, the biggest u.S. Maker of generic drugs, had hoped to launch its copycat version last year, but the fda granted j&j an additional six months of market exclusivity in return for testing the drug's safety and effectiveness in children.
Has anyone had experience using this?
