Since its original synthesis more than half a century ago [1], methotrexate (MTX) has become an established drug in several medical specialties. Developed as a specific antagonist of folic acid, this drug was shown to inhibit proliferation of malignant cells primarily by inhibiting de novo synthesis of purines and pyrimidines [2]. Hence its original use primarily as a chemotherapeutic agent, but later it was also evaluated for the treatment of rheumatoid arthritis (RA) because of its presumed antiproliferative activities [3]. For more than 15 yr now it has been an established DMARD with pronounced anti-inflammatory activity that goes beyond inhibition of folic acid metabolism [2, 4]. In fact, several studies have indicated that its anti-inflammatory effects may be due to other mechanisms, such as adenosine release, which can induce immunosuppression [5]. Although MTX is definitely one of the most
