Onsior general information

What is Onsior used for?

Onsior tablets 20mg are used for dogs to help treat and manage the pain and inflammation associated with chronic osteoarthritis.  Many dogs suffer from osteoarthritis, particularly as they age.  Osteoarthritis is caused by wear and tear of the joints, particularly in the knees and hips and can cause pain, swelling and stiffness, in the affected joint; also altered gait as weight is transferred to unaffected limbs, which affects mobility and restricts your dog’s activity.  Onsior tablets 20mg can help relieve symptoms of osteoarthritis and improve your dog’s mobility and general demeanour.  Onsior tablets 20mg can also be used to help control pain and inflammation following orthopaedic and soft tissue surgery in dogs.  Onsior tablets 20mg are only suitable for dogs with a weight no less than 2.5 kg (5.5 lbs) and are no less than 3 months of age.  Onsior tablets 20mg are not suitable for cats.  

How does Onsior work?

Onsior tablets 20mg contain robenacoxib, which is a nonsteroidal anti-inflammatory drug (NSAID) of the coxib class and has anti-inflammatory, analgesic and anti-pyretic action (reduces fever).  Onsior tablets 20mg work by blocking the production of specific chemicals called prostaglandins (PG) that mediate inflammation.  Robenacoxib in Onsior tablets 20mg is a highly selective and specific inhibitor of the enzyme cyclooxygenase 2 (COX-2) that is induced during the inflammation process and is responsible for the synthesis of inflammatory prostaglandins like PGE2, which causes pain, swelling and other symptoms of inflammation1.  Robenacoxib in Onsior tablets 20mg has minimal effect on the cyclooxygenase 1 enzyme (COX-1) that is needed for normal cellular processes, such as kidney and platelet function and also protects the gastrointestinal mucosa, which protects against gastrointestinal side effects1.  Robenacoxib in Onsior tablets 20mg enters and leaves the blood rapidly to target the site of inflammation2 so that it is fast acting, being effective within 30 minutes and lasts for 24hours.  By inhibiting the action of COX-2, Onsior tablets 20mg relieve the symptoms of inflammation, including pain and swelling.
