Otsuka Pharmaceutical Factory, Inc., the first company in the Otsuka Pharmaceutical Group, was founded as a maker of chemical compounds in 1921 in Tokushima Prefecture, Japan. The company entered the pharmaceuticals business in 1946 with the production and sales of intravenous solutions. Otsuka Pharmaceutical Co., Ltd. (OPC), established in 1964 as the core company in the Group, was initially engaged in marketing intravenous solutions and other products. In 1971 OPC became engaged in new drug development and in 1980 successfully launched a new ?-blocker and a bronchodilator. Subsequently, OPC has developed a host of innovative new drugs around the world, including an antiplatelet agent, an anti-gastritis & anti-gastric ulcer agent, and an antipsychotic formula. Through our Nutraceuticals business OPC also develops consumer products for the maintenance of day-to-day health. Pocari Sweat, launched in 1980, was followed by Calorie Mate, Amino-Value, and other original OPC products that have pioneered new market categories.
