About PRN Pharmacal

In 1978, four men, fueled by the belief that the veterinary community needed a company to service their unmet needs, each put in $5,000, their industry-specific expertise and a huge dose of optimism to found such a company. This company’s business would be dedicated to leading the industry in research and development of niche products and drug therapies that address overlooked areas of pet and animal health.

Pro Re Nata is a Latin phrase meaning as the circumstance arises. It has come to be used in prescription medicine as p.r.n. or as needed. This is how PRN® Pharmacal began and it is how we continue to view ourselves today. As true as it was in 1978, the veterinary community can be assured that PRN Pharmacal will be here when needed to provide products that improve animal health and quality of life.

Under the highest quality and rigor of Current Good Manufacturing Practices (CGMP)* and standards, we strive to provide a wide range of products for the enhancement of animal health in areas of veterinary medicine that are largely under-served. Our mission is to continually improve our products and services to meet the needs of the veterinary industry, and is driven by both our employee-ownership and a fundamental set of values.
