Initial treatment consists of NSAIDs, low dose corticosteroids. If the symptoms are not controlled then second line/disease modifying drugs (DMDs) are added. Since it is a progressive disease, spontaneous remissions are rare and joint damage occurs early, DMDs are started early and continued indefinitely with regular monitoring. 

The disease modifying drugs (DMDs/ DMARDs) used are gold, d-penicillamine, hydroxychloroquine, sulfasalazine and immuno-suppressants like methotrexate, azathioprine, cyclosporin etc.

In case of a symptomatic effect of the drug the curve resulting from the above equation is just shifted in parallel, i.e. the same disease status is achieved at a later time point, whereas in case of a disease-modifying drug the Progression/ should be decreased by the drug.

Figure 40.1. Relapse Rate Reduction, Phase 111 Studies (Class I). In the pivotal Class 1 studies of disease-modifying drugs for multiple sclerosis, gladramer acetate (GA) and higher-frequency (three times weekly) dosing of interferon beta were clearly superior to once-weekly interferon (IM) in reduction of relapse rate.

A plot of the same Emax disease progress model with a disease modifying drug is presented in Figure 21.8. In this case, as was seen previously, the drug effect persists even after the treatment is discontinued.
