Rituximab is used to treat non-Hodgkin's lymphoma, follicular lymphoma, or chronic lymphocytic leukemia. In addition, this drug can also be used in the treatment of rheumatoid arthritis when therapy with other drugs is less effective.
In cancer treatment, rituximab works by inhibiting and stopping the growth of cancer cells. Meanwhile, in the treatment of rheumatoid arthritis, this drug works by reducing inflammation by suppressing the immune system, so that symptoms such as pain and swelling in the joints can subside.
