Sanofi
Sanofi was founded in 1973[6] as subsidiary of Elf Aquitaine (a French oil company subsequently acquired by Total S.A.), when Elf Aquitaine took control of the Labaz group, a pharmaceutical company.
Synthélabo was founded in 1970 through the merger of two French pharmaceutical laboratories, Laboratoires Dausse (founded in 1834) and Laboratoires Robert & Carrière (founded in 1899). In 1973, the French cosmetics group L’Oréal acquired the majority of its share capital.
Sanofi-Synthélabo was formed in 1999 when Sanofi merged with Synthélabo. The merged companies focused on pharmaceuticals, divesting several businesses soon after the merger.
Aventis
Aventis was formed in 1999 when French company Rhône-Poulenc S.A. merged with the German corporation Hoechst Marion Roussel, which itself was formed from the 1995 merger of Hoechst AG with Cassella, Roussel Uclaf and Marion Merrell Dow. The merged company was based in Schiltigheim, near Strasbourg, France.
At the time of the merger, Rhône-Poulenc's business included the pharmaceutical businesses Rorer, Centeon (blood products), and Pasteur Merieux (vaccines)
Merieux has been in the business of selling blood products, and In the 1980s during the AIDS epidemic, Merieux and other companies were involved in scandals related to HIV-contaminated haemophilia blood products that were sold to developing nations.[12]
Merger : Sanofi-Aventis
Merger: Sanofi-Aventis
Sanofi-Aventis was formed in 2004 when Sanofi-Synthélabo acquired Aventis.
he French government played a strong role, desiring what it called a "local solution", by putting heavy pressure on Sanofi-Synthélabo to raise its bid for Aventis and for Aventis to accept the offer.
One of the largest risks in the deal for both sides, was the fate of the patents protecting Clopidogrel (Plavix) which was one of the top-selling drugs in the world at the time and the major source of Aventis' revenue.
In 2006, Iraqis infected with HIV sued Sanofi and Baxter due to HIV-contaminated haemophilia blood products sold by Merieux in the 1980s.
In 2003 Aventis entered into a collaboration with Regeneron, a New York biotechnology company.
In 2007 Sanofi-Aventis expanded on Aventis' prior relationship with Regeneron.
