From Human to Veterinary Medicine: Expanding the Role of Microneedle Drug Delivery and Diagnostic Systems

Microneedles, typically 25–2000 µm in height, can be fabricated from metals, silicon, ceramics, or polymers, allowing precise customization for specific biomedical applications. While their potential is well established in human medicine, veterinary use remains limited. Nonetheless, recent studies indicate promising applications in pain management, vaccination, diagnostics, and dermatological therapy. This study presents findings that may support broader adoption of microneedles in veterinary medicine, highlighting key parallels with human research and evaluating their main advantages and limitations. By bridging the gap between human and veterinary drug delivery, microneedle technologies can reinforce translational medicine and advance the principles of the One Health framework, promoting integrated therapeutic innovation across species.
