Our History and Heritage
LEO Pharma’s core values - Integrity, Customer focus, Innovation, Passion and Adaptability - have been at the heart of LEO Pharma since our founding in Denmark over a century ago. By translating these values into reality, LEO Pharma has developed into a world leader in dermatology (skin) and thrombosis (blood clots) through the development of innovative treatments and patient-focused offerings to improve the lives of millions around the world.
In 1908 two pharmacists, August Kongsted and Anton Antons, purchased a pharmacy in Copenhagen, Denmark, naming it ‘Københavns Løveapoteks kemiske Fabrik’. Later changing the name to LEO Pharma, Kongsted and Anton’s pharmacy grew from humble beginnings to the global organisation that it is today.

LEO Pharma started to expand outside of Scandinavia during the 1950s and 1960s and the LEO Pharma logo was first registered in 1956.

The Company established its UK presence in 1960, with a focus on improving patient quality of life and medical education programmes. This focus continues today, from our modern Berkshire offices.
In 1959, LEO Pharma’s commercial organisation in Ireland was set up as well as the manufacturing site in Dublin, Ireland. Development continued throughout the 1970s and 1980s and a topical dermatological plant was completed in 1992. Enhancements to the Dublin site, including further expansion of the topical dermatological plant, have continued since, with a new sterile facility being completed in 2008. Elsewhere in Ireland, a heparin purification plant in Cork was built in 1987, which continues to play a key role in production.
LEO Pharma UK and LEO Pharma Ireland united as a joint LEO Pharma UK/IE commercial affiliate in 2012. Since January 2017 the LEO Pharma UK/IE affiliate also acts as the central international hub coordinating activities for the ‘Region Europe North+’ cluster of LEO affiliates. In addition to the UK and Ireland the cluster comprises of Norway, Denmark, Sweden, Finland, Australia and New Zealand.
