What is the practical conversion dose when changing from epoetin alfa A brochure to help you understand how to dose and administer Aranesp, and to convert from epoetin alfa to Aranesp in patients with anemia due to CKD. IL-11 has also been shown to have non-hematopoietic activities in animals including the regulation of intestinal epithelium growth (enhanced healing of gastrointestinal lesions), the inhibition of adipogenesis, the induction of acute phase protein synthesis, inhibition of pro-inflammatory cytokine production by macrophages, and the stimulation of osteoclastogenesis and neurogenesis. Safety and Efficacy: Currently available data indicate that darbepoetin
Both drugs are costly: January 2003 prices posted by Medicare put reimbursement rates at $12.69 per 1000 units of Procrit (translating to about $534.32 for the Average Wholesale Price [AWP] for a once-a-week dose of 40,000 units) and $23.69 per 5 micrograms of Aranesp (about $994.98 for the AWP for a 3 mcg/kg dose every other week).
