Pegheal

Pegheal is a biosynthetic form of human granulocyte colony-stimulating factor (G-CSF). It is used to treat a variety of chronic and acute hematologic conditions, including malignancies, myelodysplastic syndromes, and immunodeficiencies. In malignancies, it is used to increase blood cell counts in patients undergoing chemotherapy and to prevent neutropenia (low levels of neutrophils). Pegheal is also used to increase the number of stem cells collected from the patient's bone marrow for autologous transplantation.

Uses

Pegheal is used to treat neutropenia caused by a variety of conditions, including chemotherapy, radiation therapy, bone marrow transplantation, and some immunologic disorders. It is also used to increase the number of stem cells collected from the bone marrow for autologous transplantation, and to reduce the risk of infection in patients with HIV/AIDS.

Mechanism of Action

Pegheal stimulates the production of neutrophils (white blood cells) in the bone marrow. It binds to the membrane-bound receptor G-CSFR, which activates the JAK/STAT pathway to induce the production of neutrophils. It also promotes the release of neutrophils from the bone marrow into the bloodstream.
