Novartis AG said Tuesday that third-quarter profit fell 42% from the same period last year, as the Swiss drug giant agreed to settle claims that it used rebates to get specialty pharmacies to increase prescriptions. Basel-based Novartis said net income fell to $1.81 billion, or $0.75 per share in the quarter ended in September, compared with $3.1 billion, or $1.27 share a year earlier.
