Pharmacia Stockholders Approve Merger With Upjohn: It was the last major hurdle before the deal creating the world’s ninth-biggest drug maker could be completed, the Swedish company said. Trading in new shares of Pharmacia & Upjohn Inc. will begin Friday in New York and Monday in Stockholm. The company is forecast to have annual sales of about $6.8 billion. It will be based in London but have major offices in Stockholm; Kalamazoo, Mich., and Milan, Italy. It plans to launch 29 products over the next three years, including treatments for AIDS, cancer and Parkinson’s disease, said Upjohn Co. Chairman John Zabriskie, who will be Pharmacia & Upjohn chief executive. Zabriskie would not provide details on plans to lay off 4,000 employees, but he did say the remaining 30,000 will have more secure jobs.
