Gazyva 1000 mg Injection 40 ml contains Obinutuzumab, which belongs to the class of CD20-directed cytolytic antibodies.  It is used in the treatment of chronic lymphocytic leukaemia and follicular lymphoma. This medicine works by binding to the CD20 antibody and causes lysis of B-cell lymphocytes responsible for the multiplication of cancer cells. This causes shrinkage of tumour cells and thereby prevents the growth and further spread of cancerous or non-cancerous cells.

Chronic Lymphocytic Leukaemia: It is a type of cancer that occurs in the bone marrow and blood. It increases the number of lymphocytes (a type of white blood cell). The symptoms include fever, enlarged liver, bone or joint pain, shortness of breath, weakness, and bleeding from gums or bruises.

Follicular lymphoma: It is a type of non-Hodgkins lymphoma with slow-growing (chronic) cancer with abnormal growth of B lymphocytes, a type of white blood cells that help fight infection. This results in the buildup of too many B lymphocytes in the blood, lymph nodes, bone marrow, and spleen.
