ERYPAR vs ILOSONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Erypoietin receptor agonist; stimulates erythropoiesis by binding to erythropoietin receptors on erythroid progenitor cells.
Erythromycin (ILOSONE) binds to the 50S subunit of bacterial ribosomes, inhibiting peptide chain elongation and protein synthesis by blocking translocation.
Intravenous: 100 mg every 12 hours for 7 to 14 days.
Erythromycin (Ilosone) base or stearate: 250-500 mg orally every 6 hours. Estolate: 250-500 mg orally every 6 hours. Maximum dose 4 g/day.

Terminal elimination half-life is approximately 3-5 hours in adults with normal renal function; may be prolonged to >10 hours in severe renal impairment
1.5-2 hours in adults; prolonged in hepatic impairment (up to 5-6 hours)
Primarily renal excretion of unchanged drug (~75%) and metabolites; biliary/fecal elimination accounts for ~20%
Renal (2-5% unchanged), biliary/fecal (majority, >90% as metabolites and unchanged drug)
