Sanofi-Aventis (SNY) : Headquartered in Paris with operations in more than 100 countries, Sanofi makes a wide array of drugs, including Allegra (allergies), AmbienCR (a prescription sleeping aid), and Nasacort (a nasal spray).
However, Kimberley Thacker, vice president at Sanofi, emphasizes that the active ingredient in Ambien and AmbienCR has been around for years and that the drug has helped patients sleep through a combined 14 billion nights in a real-world setting.
