Mechanism :

Has same effects as endogenous erythropoietin. Binding of erythropoietin to the erythropoietin receptor leads to receptor dimerization, which facilitates activation of JAK-STAT signalling pathways within the cytosol. Activated STAT (signal transducers and activators of transcription) proteins are then translocated to the nucleus where they serve as transcription factors which regulate the activation of specific genes involved in cell division or differentiation.


Indication :

• Anemia in Premature patients

• Anemia in Chronic Renal Failure

• Anemia in Cancer patients.


Contraindications :

Hypersensitivity to epoetin alfa or albumin or mammalian cell-derived products

Cancer patients whose anemia is caused by factors other than chemotherapy.
