Veterinary medicine

Orion is one of the best-known companies for veterinary medicines in the Nordic countries. We manufacture and market our own proprietary veterinary medicines and a wide range of generic medicines. Orion also markets and sells veterinary medicines manufactured by several international companies.

Orion’s own proprietary medicines are Clevor® (ropinirole), Domosedan® (detomidine), Domitor® (medetomidine), Antisedan® (atipamezole), Dexdomitor® (dexmedetomidine), Domosedan Gel® (detomidine) and Sileo® (dexmedetomidine).

Domosedan is used for sedating large animals, especially horses, for diagnosis and procedures by a veterinarian. It also acts as an analgesic. Domosedan Gel is a prescription medicine used for sedation to facilitate restraint for minor husbandry procedures.

Domitor and Dexdomitor are sedatives for small animals such as cats and dogs. Antisedan is a substance that rapidly and safely revives an animal following sedation with Dexdomitor or Domitor.

Sileo is a prescription medicine indicated for alleviation of acute anxiety and fear associated with noise in dogs.

Clevor is a eye-drop treatment for poisoning in dogs.

Examples of Orion’s other veterinary products include Kefavet® (cephalexin), an antibiotic for cats and dogs, and Comforion® (ketoprofen) NSAIDs particularly for cattle.

Besides the medicinal products, for poultry Orion has developed Broilact®, a unique Competitive Exclusion (CE) product providing a refined selection of bacteria that establish and develop a healthy adult type microflora in the intestine of chickens, turkeys, geese, pheasants, quails and partridges.
