The American pharmaceutical company Johnson & Johnson has agreed to pay more than two billion dollars to settle allegations that it promoted powerful psychiatric drugs for unapproved uses in children, seniors and disabled patients. The settlement is one of the biggest involving a drug firm in the US. The allegations include paying kickbacks to doctors and pharmacies to recommend and prescribe Risperdal and Invega, both anti-psychotic drugs, and Natrecor, which is used to treat heart failure.
