From Molecules to Veterinary Medicines

Like humans, animals sometimes need medicines to stay or get healthy. For over 90 years, Bayer has invested in the research and development of new medicines to support the health of both companion animals and farm animals.





Developing a new medicine for animals is very similar to making a new medicine for humans. It requires a big investment and a long time, usually around eight to ten years. During this time, highly qualified scientists from a variety of disciplines filter through an enormous number of compounds to find a suitable active ingredient. In fact, between 5,000 and 10,000 compounds are studied, out of which only four or five potential candidates are further optimized. The best candidates from this small number are then rigorously tested in clinical studies. Ultimately, only one substance will be approved by government authorities and become available to veterinarians, farmers and pet owners.


Increasingly, people live in close proximity with animals or depend on them for animal proteins. Keeping this close relationship healthy is not just a responsibility towards animals, but it also protects humans from the transmission of disease pathogens. With this brochure, we invite you to join us on a journey to see how a molecule becomes a medicine to help animals. We hope you will share our passion for using science to keep animals healthy or treat them when they are sick – thus realizing Bayer’s purpose ‘Science For A Better Life’.
