Laboratorios Karizoo

Laboratorios Karizoo is a long-established Spanish manufacturer specializing in the development and distribution of pharmaceuticals—primarily small-molecule drugs such as antibiotics—and nutritional products for animal health. Founded in 1983 and now part of Alivira Animal Health since 2016, the company operates out of Caldes de Montbui (Barcelona), serving both local (European) and international markets with GMP-certified facilities. Its portfolio includes well-known antibiotic brands (e.g., Amoxicillin, Doxycycline) as well as nutraceuticals, and it exports widely across Europe, Africa, and Asia. The focus remains on improving farm animal welfare, pets’ quality-of-life, and supporting veterinarians through innovative, veterinary-specific solutions. The firm does not develop human therapeutics nor conduct clinical trials typical to human biotech/pharma companies, but rather focuses on commercialized vet pharma/nutritionals with global reach.
