CHIESI is established in France since 1992 with its subsidiary Promedica.

Chiesi France is the only foreign family laboratory in France present on the entire value-added chain: R & D / production and distribution / supply of medicines to the medical profession and patients. 

In 1999, the Italian group has strengthened its presence in France with the acquisition of the Logeais Group and founded CHIESI S.A.S.


Subsidiary of first importance, it intends to fully participate in the development of the Group and helps actively the Group to achieve its goals.


Chiesi S.A.S. has created its own identity. Like the Group, the French subsidiary has developed its expertise in the field of pulmonology.


 The head office is based in Bois-Colombes (92) and the French plant in Chaussée-Saint-Victor near Blois (41).

The France subsidiary has 350 employees (230 people at headquarters and field force / 26 people in R&D / 103 people at the factory).

In 2019 his turnover reached 121 million euros.


The respiratory is placed at the heart of the expertise of the laboratory Chiesi, which constitutes a real singularity in the traditional pharmaceutical industry.

Other axes are also continued in hospital products, in particular in neonatology, where CHIESI SAS has proven expertise for many years.

CHIESI SAS human size combined with flexibility and adaptability values, the Group subsidiaries accountability policy, the entrepreneurial spirit of management, allow all the collaborators to share the Group ambitions, measure their personal contribution and demonstrate their sense of innovation and commitment.




The Chiesi Group history dates back to July 6, 1935 when Giacomo Chiesi, a pharmacist dreaming of research, bought a pharmaceutical laboratory in Parma to make his dream come true.


The small province laboratory - which had two employees in its early days - has become an international company with more than 5000 employees.


This progress, based on the Chiesi family determination and passion for research, has transformed the original idea into a business in constant development.


In the late 70s, while the first foreign subsidiary opened in Brazil, the company developed its international dimension to become a group present on the 5 continents, through its 26 subsidiaries, and whose medicinal products are now successfully distributed in more than 80 countries.


Chiesi history is the story of a personal dream that became a collective dream: creative innovation with the aim of providing effective treatments.


With more than 85 years of existence Chiesi continues to live this principle every day with passion and determination..
