Background: The veterinary pharmaceutical industry has shown significant growth in recent
decades. Several factors contribute to this increase as the demand for the improvement of the
quality of life of both domestic and wild animals, together with the need to improve the quality,
productivity, and safety of foodstuffs of animal origin.
Methods: The goal of this work was to identify the most suitable medicines for animals that focus on
drug delivery routes as those for humans, although they may have different devices, such as collars
and ear tags.
Results: Recent advances in drug delivery systems for veterinary use are discussed, both from academic
research and the global market. The administration routes commonly used for veterinary medicines
are also explored, while special attention is given to the latest technological trends to improve
the drug performance, reducing the number of doses, animal stress, and side effects.
Conclusion: Drug delivery system in veterinary decreased the number of doses, side effects, and animal
stress that are a small fraction of the benefits of veterinary drug delivery systems and represent a
significant increase in profit for the industry; also, it demands investments in research regarding the
quality, safety, and efficacy of the drug and the drug delivery systems.
