Overview | olatinib (olatinib), a new type of JAK inhibitor, it also inhibits the function of jak1-dependent cytokines in some anti-allergic, inflammatory and pruritic responses. Studies have confirmed that experimental animals (dogs) in accordance with the 0.4-0.6mg/kg dose orally, twice a day, for the treatment of itching due to atopic dermatitis is safe and effective, and showed better efficacy than oral corticosteroids such as prednisolone. During the treatment period, administration of olatinib relieved the itch within 24 hours, with more than 70% of the experimental animals reducing greater than 50% of the itch response at Day 7. Currently, olatinib has been approved by the US FDA in 2013 for the control of pruritus and atopic dermatitis caused by allergic dermatitis in dogs. However, although the efficacy of olatinib on pet dog allergic skin disease is better, but its range of action is narrow, on the one hand, it has little effect on the cytokines that do not participate in the activation of JAK1, on the other hand, its effect on allergic reaction is only manifested in the inhibition of mast cell degranulation, that is, the release of allergic mediators, and can not fundamentally and directly block the binding of allergic mediators and related receptors, it can not fundamentally block the occurrence and development of allergic skin diseases. |
| olatinib was approved by the US FDA in to control pruritus and atopic dermatitis caused by allergic dermatitis in dogs. Olatinib (PF03394197) is a novel JAK and JAK1-dependentcytokines inhibitor with an IC50 of 10-99nm (jakfamy members) and 36-JAK1-dependentcytokines nm (), respectively. Olatinib is a very potent JAK1 inhibitor and also inhibits JAK1-dependentcytokines of its function in some anti-allergic, inflammatory and pruritic responses. It has little effect on cytokines that are not involved in the activation of JAK1. By the oral route, treatment of olatinib at 0.4-0.6mg/kg twice daily is safe and effective for the treatment of pruritus due to allergic dermatitis. During the treatment period, administration of olatinib relieved the itch within 24 hours, and in the experiment, more than 70% of the experimental animals (dogs) reduced the itch response by more than 50% at Day 7. |
