How does Onsior work?
Onsior is quickly absorbed. Peak blood concentrations are attained rapidly with median Tmax values generally occurring within 0.5 hr.*
Onsior, a highly protein-bound NSAID, persists longer at the site of inflammation than in the blood because inflammatory exudate is rich in plasma proteins, thereby providing sustained drug levels at the site of action.*2
Onsior is rapidly eliminated from the blood. The mean blood T1/2 is approximately 1.7 hrs for Onsior Tablets for Cats.* The terminal T1/2 is approximately 1.1 hrs. for Onsior injection for Cats.***
* Tablets dosed at 1 mg/kg without food.
**Clinical relevance unknown.
*** Injection dosed at 2 mg/kg.
