Merrell Dow Pharmaceuticals

Merrell Dow Pharmaceuticals was a prominent American pharmaceutical company established in 1981 through the merger of the ethical drug business of Richardson-Merrell and the pharmaceutical division of Dow Chemical. Headquartered in Cincinnati, Ohio, the company became a significant player in the global healthcare market, focusing on the development of small molecule therapies across respiratory, cardiovascular, and infectious disease areas. Its portfolio included landmark products such as the non-sedating antihistamine Seldane and the smoking cessation aid Nicorette. In 1989, Dow Chemical merged Merrell Dow with Marion Laboratories to form Marion Merrell Dow, which was later acquired by Hoechst AG. Today, the legacy of Merrell Dow's research and products resides within the global pharmaceutical leader Sanofi.
