Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Erythromycin, a macrolide antibiotic, binds to the 50S ribosomal subunit of susceptible bacteria, inhibiting protein synthesis. At high concentrations, it may also inhibit RNA synthesis.
Erythromycin binds to the 50S subunit of bacterial ribosomes, inhibiting protein synthesis by blocking peptidyl transferase activity and preventing translocation of peptides.
Erythromycin ethylsuccinate 400 mg orally every 6 hours. For severe infections, up to 4 g/day in divided doses.
Erythromycin base (Ilotycin): 250 mg orally every 6 hours or 500 mg every 12 hours; maximum 4 g/day. For IV: 15-20 mg/kg/day continuous infusion or divided every 6 hours.

1.5-2.0 hours in adults with normal renal function; may be prolonged in hepatic impairment (up to 5-6 hours) but not significantly changed in renal disease.
Terminal elimination half-life is 1.5-2 hours in adults, prolonged to 4-6 hours in severe renal impairment (CrCl <10 mL/min), requiring dose adjustment.
Primarily hepatic (biliary) excretion of unchanged drug and metabolites; approximately 2-5% renal excretion of unchanged drug; 5-15% fecal elimination.
Approximately 80-90% renal excretion as unchanged drug via glomerular filtration and tubular secretion; 10-15% biliary/fecal elimination.
