Imfinzi 500mg Injection contains Durvalumab, an advanced immunotherapy medicine belonging to the class of anti-PD-L1 monoclonal antibodies. It is used to treat specific types of cancer, including non-small cell lung cancer (NSCLC), small cell lung cancer (SCLC), and biliary tract cancers. Imfinzi works by strengthening the body’s immune response against cancer cells, allowing immune cells to recognize and destroy tumors more effectively.
This medicine is administered intravenously under strict medical supervision and is not recommended for children or adolescents under 18 years of age.

It is often used alone or in combination with chemotherapy agents such as cisplatin, carboplatin, or gemcitabine, depending on the cancer type and stage.
Imfinzi works by blocking PD-L1 (programmed death-ligand 1), a protein expressed on cancer cells that suppresses immune activity. When PD-L1 binds to immune cells, it prevents them from attacking cancer. By inhibiting this interaction, Imfinzi reactivates T-cells, enabling the immune system to recognize, target, and destroy cancer cells more efficiently. This immune-mediated action can help slow or stop cancer progression.
