With a legacy that stretches over five decades, Norbrook Laboratories is one of the largest, family-owned veterinary pharmaceutical companies in the world. Headquartered in Newry, Northern Ireland, the company has become synonymous with excellence in the development, manufacture, and global distribution of animal health products—contributing significantly to the well-being of livestock and companion animals across more than 100 countries. Founded in 1969 by Lord Ballyedmond, Norbrook was built on a vision to make high-quality veterinary medicines accessible to markets around the globe. What began as a small operation has grown into a vertically integrated pharmaceutical powerhouse, with capabilities that span research and development, manufacturing, quality control, and international distribution. At every step, Norbrook has stayed true to its founding mission: to deliver safe, effective, and affordable veterinary solutions that support animal health and sustainable farming.

Norbrook’s product portfolio reflects its commitment to meeting the needs of veterinarians, farmers, and pet owners alike. The company offers a wide array of veterinary medicines, including antibiotics, antiparasitics, NSAIDs, anesthetics, and nutritional supplements. Its products are used to treat conditions ranging from respiratory and enteric diseases in livestock to osteoarthritis and post-surgical pain in companion animals.

Among Norbrook’s most well-known products are Noroclav, a broad-spectrum antibiotic; Loxicom, an NSAID for pain and inflammation; and Flunixin Injection, a staple anti-inflammatory used widely in cattle and horses. These products, backed by rigorous research and manufactured to exacting standards, have earned the trust of veterinarians and producers across global markets. A major strength of Norbrook lies in its robust research and development infrastructure. The company continuously invests in novel formulations, improved drug delivery systems, and lifecycle management strategies that keep its offerings relevant and effective. Its state-of-the-art R&D center in Northern Ireland is staffed with experienced scientists who focus on developing generics as well as new products that address emerging animal health challenges.

One of the company’s key differentiators is its vertical integration model. Unlike many competitors who outsource parts of the production process, Norbrook retains full control over every aspect—from formulation and manufacturing to packaging and distribution. This level of integration ensures consistency, cost-efficiency, and the flexibility to respond quickly to market demands and regulatory changes.

Norbrook’s manufacturing facilities are among the most advanced in the veterinary pharmaceutical industry. Spread over a sprawling campus in Newry, the company’s production lines are certified to the highest international quality standards, including EU GMP and FDA regulations. Its ability to meet stringent quality requirements has enabled Norbrook to gain approvals and market access in some of the most regulated regions of the world, including North America, Europe, Asia, and Australasia. In addition to its scientific and manufacturing excellence, Norbrook places a strong emphasis on customer support and education. The company works closely with veterinarians and farmers, offering technical guidance, training programs, and product support to ensure the optimal use of its medications. This customer-centric approach has helped build lasting relationships and a reputation for reliability in the veterinary community.

As global agriculture continues to evolve, Norbrook is playing an important role in addressing the sector’s most pressing challenges. From improving disease control and animal welfare to supporting responsible antibiotic use, the company’s products and services contribute directly to the efficiency and sustainability of livestock production. At the same time, Norbrook is expanding its presence in the companion animal market—recognizing the growing demand for specialized veterinary care for pets. “At Norbrook, we believe in innovation with purpose. Our goal is not just to develop and manufacture veterinary medicines, but to support those who care for animals—whether on the farm or in the home.”

Corporate responsibility is also a core value at Norbrook. The company is committed to environmental sustainability, community engagement, and ethical business practices. Its operations are guided by a clear framework for minimizing environmental impact, ensuring workforce well-being, and contributing positively to the communities in which it operates.

Looking ahead, Norbrook is well-positioned for growth. The company is expanding its product pipeline, enhancing its regulatory capabilities, and investing in digital technologies that can provide veterinarians with better data and decision-making tools. At the same time, Norbrook remains agile—ready to respond to new market demands and public health imperatives such as antimicrobial resistance and zoonotic disease management. In a veterinary landscape that demands both innovation and accountability, Norbrook Laboratories continues to lead with vision, science, and an unwavering dedication to animal health. Its global reach, technical excellence, and customer-first mindset make it not just a pharmaceutical manufacturer, but a true partner in animal care.
