sanofi-aventis is the world's 3rd largest pharmaceuticals company, headquartered in Paris, France.
Sanofi-Aventis also produces a line of r-DNA/GE/GM insulins under the brand name Insuman. These insulins are available in Europe and many other countries world-wide, but not in the US or in Canada. Not all products are available in all countries and some may be available in one delivery form (pen or vial), but not another. Insuman pens and cartridges use the same Aventis Opti-Clik delivery system as Lantus does.
Some of their products listed here are helpful for diabetic animals.
