Cortisone

Cortisone ( /ˈkɔrtɨsoʊn/ or /ˈkɔrtɨzoʊn/; 17-hydroxy-11-dehydrocorticosterone) is a steroid hormone. It is one of the main hormones released by the adrenal gland in response to stress. In chemical structure, it is a corticosteroid closely related to corticosterone. It is used to treat a variety of ailments and can be administered intravenously, orally, intraarticularly, or transcutaneously. Cortisone suppresses the immune system, thus reducing inflammation and attendant pain and swelling at the site of the injury. Risks exist, in particular in the long-term use of cortisone.
