Sponsor's own description

Among three MAPK families, paroxetine was found to be able to decrease the phosphorylation of ERK. It was reported that paroxetine attenuates the symptoms of collage induced arthritis rats due to its inhibitory effect on T cell activation and infiltration to synovial tissue via suppression of ERK pathway. This study aimed to evaluate the therapeutic efficacy of paroxetine in rheumatoid arthritis. Paroxetine prevents the joint inflammation which is at the very early stage. paroxetine could inhibit GRK2 with selectivity over other GRKs. Medications developed for maintaining the immunologic equilibrium. such as GRK2 inhibitors, will be the novel trends in RA treatment that could avoid the adverse side effects that are common with current treatment options.
