Research Excerpts

Overview

Robenacoxib (Onsior™) is a non-steroidal anti-inflammatory drug developed for canine and feline use for the control of pain and inflammation. The drug is a novel and highly selective inhibitor of COX-2 in dogs and cats and because of its acidic nature is regarded as being tissue-selective.

Pharmacokinetics

The population pharmacokinetic analysis performed showed that the 1-2mg/kg dosage chosen provided consistent robenacoxib exposure in a wide range of canine patients. Results from previous feline studies showed that, despite a short half-life in blood, the effect of robenayxib persisted for 24 h in clinical studies.

Roles (3)

RoleDescription
non-steroidal anti-inflammatory drugAn anti-inflammatory drug that is not a steroid. In addition to anti-inflammatory actions, non-steroidal anti-inflammatory drugs have analgesic, antipyretic, and platelet-inhibitory actions. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins.
non-narcotic analgesicA drug that has principally analgesic, antipyretic and anti-inflammatory actions. Non-narcotic analgesics do not bind to opioid receptors.
cyclooxygenase 2 inhibitorA cyclooxygenase inhibitor that interferes with the action of cyclooxygenase 2.
