Halopredone (THS-201; (17,21-bis(acetyloxy)-2-bromo-6beta,9-difluoro-11beta-hydroxypregna-1,4-diene-3,20-dione; halopredone acetate; Topicon) is a highly topical corticosteroid. When it is used for intraarticular injections, the effects last longer than any other steroids which have been used, and it has less general effects. Halopredone acetate is used for arthritis and osteoarthritis (OA) patients. For RA patients, mean dose for a wrist is 12.5 mg and that for a knee is 25 mg. About 90% cases showed effectiveness and in about 45% cases the duration of effect is longer than 4 weeks. More than half cases of OA showed also improvements. It also possesses positive anti-inflammatory properties in dermatologic patients.
