Cancer patients receiving myelosuppressive chemotherapy: The recommended starting dose of Filgrastim is 5 mcg/kg/day. Doses may be increased in increments of 5 mcg/kg for each chemotherapy cycle. Cancer patients receiving bone marrow transplant: The recommended dose of Filgrastim following bone marrow transplantation is 10 mcg/kg/day. During the period of neutrophil recovery, the daily dose should be titrated against the neutrophil response as follows: Absolute Neutrophil Count (ANC): Dose adjustment ANC>1000/mm3 for consecutive 3 days Reduces to 5 mcg/kg/day. Then, If ANC remains >1000/mm3 for consecutive 3 days Discontinue drug. Then, If ANC remains <1000/mm3 for consecutive 3 days Resume at 5 mcg/kg/day. Patients with chronic neutropenia: The recommended daily starting dose is 5 mcg/kg/day in idiopathic neutropenia. Peripheral blood progenitor cell collection and therapy: The recommended starting dose is 10 mcg/kg/day. Dose may be adjusted as required. HIV infection and persistent neutropenia Initial: 1 mcg/kg/day, up to 4 mcg/kg/day until neutrophil count is normalized. Maintenance: 300 mcg/day. Max: 4 mcg/kg/day. Contraindication ::

Drug Mode of Action ::  

Filgrastim is a granulocyte-colony stimulating factor which binds to cell surface receptors on haemetopoietic cells thus stimulating the development of granulocytes to increase their migration and cytotoxicity.

Drug Interactions ::

Myelosuppressive antineoplastic agents. Drugs which may potentiate the release of neutrophils e.g. lithium.
