G. D. Searle & Company

In , Gideon Daniel Searle founded Searle in Omaha, Nebraska. The company incorporated in 1908 and established headquarters in Skokie, Illinois in 1941. Between 1977 and 1985, Donald Rumsfeld was CEO, and then president, of Searle. In 1985, he negotiated the acquisition of Searle by Monsanto Corporation. In 1993, a team of researchers at Searle Research and Development filed a patent application for celecoxib, which Searle developed and which became the first selective COX-2 inhibitor to be approved by the FDA on December 31, 1998. Control of this blockbuster drug was often mentioned as a key reason for Pfizer's acquisition of Pharmacia. Monsanto merged with Pharmacia & Upjohn in 2001, including the Searle pharmaceutical assets. After spinning off its agrochemical and biotechnical business units under the Monsanto name, the new company (known as Pharmacia) was acquired by Pfizer in 2003. == Products ==

The company manufactures prescription drugs and nuclear medicine imaging equipment. Searle is known for its release of Enovid, the first commercial oral contraceptive, in 1960. In 1996, the FDA removed all restrictions on the use of aspartame, which enabled its use in heated and baked goods. G. D. Searle's patent on aspartame was extended in 1981 and ultimately expired in December 1992. == References ==
