Johnson & Johnson executives deceived South Carolina doctors about the safety of the antipsychotic drug Risperdal, and the drugmaker should be held liable for that deception, a lawyer said.

J&J made misleading claims about Risperdal’s health risks and effectiveness in a letter to more than 7,000 South Carolina doctors and that violated consumer protection laws, John Simmons, a lawyer for the state, said in closing arguments of the trial of a lawsuit seeking at least $360 million in penalties.
