An Anti-Psychotic Drug With its Own Issues: AstraZeneca’s Seroquel – German Patent Tossed

AstraZeneca’s (AZN) big selling Seroquel, an anti-psychotic drug with annual sales well over $1 billion, suffered the loss of its German patent, according to an AP news dispatch.

The setback comes in the wake of questions about Seroquel’s heavy prescribing by the U.S. military for off-label uses, as YCharts has reported.
