NEW YORK — The head of troubled pharmaceutical company Valeant has been hospitalized. An emailed statement from Valeant spokeswoman Laurie Little says CEO Michael Pearson has been admitted for "severe" pneumonia. No other details were given. Last week, Valeant Pharmaceuticals Inc. slashed its fourth-quarter financial predictions and issued a profit outlook for 2016 that was short of Wall Street's estimate. Its sales have been hurt after scrutiny from Congress and the media led it to end a controversial distribution arrangement with the Philidor mail-order pharmacy. The Canadian company's shares have dropped 57 percent from an August record high. Valeant announced Dec. 15 it has reached a new distribution deal with Deerfield-based Walgreens. Valeant said the agreement will help to lower the prices of its branded prescription-based dermatological and ophthalmological products by 10 percent.
