Arcalyst Mechanism of Action
Available by prescription only, Arcalyst® (rilonacept) is used to treat a group of rare genetic conditions called cryopyrin-associated periodic syndromes (CAPS). These conditions cause inflammation in the body, and include Muckle-Wells syndrome (MWS) and familial cold autoinflammatory syndrome (FCAS). This medication is a type of interleukin-1 beta (IL-1β) blocker.
Arcalyst works by blocking the actions of interleukin-1 beta (IL-1β), which is a protein in the immune system that causes inflammation in the body. People with CAPS have increased levels of IL-1β, which leads to inflammation in the body. By blocking the action of IL-1β, Arcalyst reduces CAPS symptoms.
