Rituxim Injection 10 mg/ml contains Rituximab, a monoclonal antibody used in the treatment of certain cancers and autoimmune diseases. It works by targeting specific proteins on the surface of B-lymphocytes (a type of white blood cell), helping to destroy abnormal or overactive cells. This targeted therapy is widely used in oncology and immunology for its effectiveness in controlling disease progression.

Composition

• Active Ingredient: Rituximab 10 mg/ml

Indications

Rituxim Injection is indicated for the treatment of:

• Non-Hodgkin’s lymphoma
• Chronic lymphocytic leukemia (CLL)
• Rheumatoid arthritis (in combination with methotrexate)
• Granulomatosis with polyangiitis and microscopic polyangiitis
• Certain autoimmune disorders involving B-cell dysfunction

Mechanism of Action

Rituximab is a chimeric monoclonal antibody that specifically binds to the CD20 antigen present on B-cells. Once bound, it leads to the destruction of these cells through immune-mediated mechanisms such as complement-dependent cytotoxicity and antibody-dependent cellular cytotoxicity. This results in reduced abnormal B-cell activity and helps control disease symptoms.

Dosage and Administration

• Administered as an intravenous infusion under the supervision of a qualified healthcare professional
• Dosage and frequency depend on the specific condition being treated and patient response
• Pre-medication (such as antihistamines and antipyretics) may be given to reduce infusion-related reactions
• Infusion rate is usually started slowly and increased gradually

Benefits

• Targeted therapy with high effectiveness in B-cell related conditions
• Helps reduce tumor burden in certain cancers
• Controls symptoms of autoimmune diseases
• Can improve long-term disease outcomes

Possible Side Effects

Common side effects may include:

• Infusion-related reactions (fever, chills, rash)
• Fatigue
• Nausea
• Headache

Serious side effects may include:

• Severe infusion reactions
• Infections due to immune suppression
• Reactivation of hepatitis B
