Pfizer first came to the Indian market in 1950, through a company named Dumex Limited. The first production facility was set up at Darukhanna in Mumbai, where products like Protinex and Isonex (isoniazid - an anti -TB drug) were manufactured. Subsequently, this plant also produced Becosules and Corex, both of which remain mega products till date. Two other manufacturing sites, which were established during the eighties, one for organic synthesis in West Bengal and the other for formulations in Gujarat, were both shut down.In 1960, Pfizer established a large and modern plant at Thane, near Mumbai, which housed manufacturing, quality control and product research facilities. This plant has won a number of national safety awards.Recently, the Thane plant has undergone an upgradation of its facilities to align with Pfizer global manufacturing standards
