APOQUEL® interrupts the itch cycle, providing dogs fast and safe relief

Apoquel Professional MOA ItchCycle Image
  1. EXPOSURE: Allergens enter via the skin, often due to a disrupted or dysfunctional epidermal barrier1
  2. SENSITIZATION: Allergens are detected by the immune system, priming the immune cells to respond to the allergens in the future1
  3. CYTOKINE RELEASE: Exposure to allergens triggers T-cell activation and the release of itch- and inflammation-causing cytokines such as IL-2, IL-4, IL-6, IL-13 and IL-311
  4. JAK ENZYME ACTIVATION: IL-31 activates peripheral nerves via the JAK-STAT pathway, resulting in transmission of the itch signal to the brain2
  5. ITCH/SCRATCH STIMULATION: The itch signal in the brain triggers scratching and other pruritic behaviors. This, combined with cytokine-induced inflammation, further disrupts the epidermal barrier1,3
  6. EPIDERMAL DAMAGE: The weakened barrier makes the dog more vulnerable to transepidermal allergen entry, thus restarting and perpetuating the cycle of itch1,3
