ARMLUPEG

PEGFILGRASTIM-UNNE
Oncology Approved 2025-11-28

Armlupeg is a leukocyte growth factor indicated for use in adult and pediatric patients, including newborns. It is primarily used to reduce the risk of infection, specifically febrile neutropenia, in patients with non-myeloid malignancies undergoing myelosuppressive chemotherapy. Additionally, the drug is approved to improve survival rates in individuals who have experienced acute exposure to myelosuppressive doses of radiation. It is not intended for the mobilization of peripheral blood progenitor cells during hematopoietic stem cell transplantation.

How ARMLUPEG Works

Armlupeg functions as a colony-stimulating factor that targets hematopoietic cells. The drug works by binding to specific receptors located on the surface of these cells. This binding action triggers the proliferation, differentiation, and commitment of the cells, ultimately leading to their functional activation. By stimulating these biological processes, the medication helps manage the effects of myelosuppression.
