More publications in the medical literature have described the clinical eff
icacy and toxicity of methotrexate (MTX) than of any other drug ever used f
or rheumatic diseases. A knowledgeable clinican can thus rely on evidence-b
ased medicine to guide the use of this agent. Because MTX is not remission-
inducing, many new therapies are being combined with it in order to achieve
a greater therapeutic response. This trend will likely continue and expand
as more novel agents are introduced.
