Drug maker AstraZeneca has filed a suit in the United States that seeks to extend its exclusive rights on some forms of its antidepressant drug Seroquel until December.

The Anglo-Swedish company said Tuesday that it had filed its suit in the U.S. District Court in Washington, D.C.

The suit seeks to overturn a ruling last week by the U.S. Food and Drug Administration that generic copies of the drug would not have to carry the same warnings about possible side effects – including suicidal thoughts and elevated blood sugar – that were required of AstraZeneca.

The patent on the active ingredient in Seroquel and Seroquel XR expired in September.

Seroquel was AstraZeneca’s second best-selling product, and the fifth biggest seller in the United States.
