Leiras

Leiras is a prominent Finnish pharmaceutical company that currently operates as a subsidiary of Takeda. Established in 1946, the company is historically significant for its pioneering work in women's health, specifically the development of the levonorgestrel-releasing intrauterine system, Mirena. After a series of corporate transitions involving Schering AG and Nycomed, Leiras was integrated into Takeda's global operations following the 2011 acquisition of Nycomed. The company now focuses on the commercialization of specialty pharmaceuticals and over-the-counter products within the Finnish and Nordic markets. Its current portfolio emphasizes therapeutic areas such as gastroenterology, oncology, and rare diseases.
