Sumitomo Pharma Co., Ltd. (住友ファーマ株式会社, Sumitomo Fāma Kabushiki-Gaisha) is a pharmaceutical company based in Japan. Its headquarters are in Chuo-ku, Osaka.[5]

The original Dainippon Pharmaceuticals (Dainippon Seiyaku) was established in 1885 by Nagayo Sensai, a graduate of Tekijuku – the first private medical school in Japan established by Ogata Kōan. It was set up as a wholly privately owned company funded by individuals from Tokyo and Osaka, with the land and buildings lent by the government. Technical expertise for the enterprise was provided by Shibata Shokei and Nagai Nagayoshi.

The company started its operation in 1885 with equipment imported from Germany. The main products were tincture and other similar drugs listed in the Japanese Pharmacopoeia. Among them was ephedrine, an anti-asthma drug invented by Nagai. In 1893, however, Nagai left the company and the business started to post operating losses. In 1898 it was acquired by Osaka Seiyaku.

The company is most well known for producing Philopon during WWII for the Imperial Japanese military.

(Osaka Pharmaceutical).[6]

Another origin of the company began as Sumitomo Pharmaceuticals, incorporated in 1984 as a subsidiary of Sumitomo Chemical (holding 77.8% of the share as of 2006).[7] Dainippon and Sumitomo merged on October 1, 2005, to create Dainippon Sumitomo Pharma.[8] As a result, Sumitomo Chemical has 50.2% ownership in Dainippon Sumitomo Pharma as of March 31, 2014.[2]

On April 1, 2022, the company was renamed from Sumitomo Dainippon Pharma to Sumitomo Pharma.

In September 2016, the Sunovion subsidiary announced it would acquire Cynapsus Therapeutics for approximately $624 million, to expand Sunovion's central nervous system drug portfolio. With the deal, Sunovion would acquire Cynapsus’ then-Phase III Parkinson's disease candidate drug APL-130277,[10] a sublingual formulation of apomorphine.[11]

In September 2019, Sumitomo Dainippon Pharma announced a $3B upfront acquisition of five Roivant Sciences subsidiaries, including Urovant and Enzyvant[12]

In October 2022, Sumitomo Pharma announced the acquisition of all outstanding shares in Myovant, a former Roivant Sciences subsidiary it was previously a majority owner of, valuing the company at $2.9B.[13]
