Early 1990s, DMARDs as the new drug for RA treatment came into market, and the number of DMARDs has been increased every year. These drugs are recognized to have several advantages in treatment of RA, however, disadvantages are also reported, i.e., (1) high incidence of side effects, (2) high non-responder population, (3) decreased efficacy in chronic treatment, and (4) slow starting of the efficacy.
