[Drug therapy of ankylosing spondylitis].

Ankylosing spondylitis has to be treated with NSAID's in order to influence the inflammatory process and thus reducing pain and slowing down the stiffening of the vertebral column. For this purpose, apart from the NSAID's Sulphasalazine is used. As a symptomatic treatment of pain and muscle spasm simple analgesics and muscle relaxants can be used. In peripheral arthritis a local treatment with intraarticular steroids can be useful, and sometimes a radiosynoviorthesis can stop the inflammation for a longer period. In case of osteoporotic fractures prescription of calcitonin may be considered.
