AstraZeneca takes action over rival move

A legal row erupted today between drugs giant AstraZeneca and a rival seeking to produce copies of its best-selling treatment for schizophrenia.

AstraZeneca revealed it has gone to the courts in the United States to stop Israeli firm Teva Pharmaceuticals from making cheap versions of Seroquel, which generates more than £1.5bn (€2.2bn) in sales every year.
