Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Erythromycin (E.E.S.) binds to the 50S subunit of bacterial ribosomes, inhibiting peptide chain elongation and protein synthesis. It also exhibits prokinetic effects on the gastrointestinal tract via motilin receptor agonism.
Binds to the 50S ribosomal subunit, inhibiting bacterial protein synthesis by blocking the translocation step.
250-500 mg every 6 hours orally or 15-20 mg/kg/day IV divided every 6 hours.
250-500 mg orally every 6 hours or 500-1000 mg intravenously every 6 hours; maximum 4 g/day.

1.5-2 hours in adults with normal renal function; prolonged to 4-6 hours in patients with hepatic impairment; may be shorter in children.
Clinical Note
moderateErythromycin + Norfloxacin
"Erythromycin may increase the QTc-prolonging activities of Norfloxacin."
Clinical Note
moderateErythromycin + Teriflunomide
"The serum concentration of Teriflunomide can be increased when it is combined with Erythromycin."
Clinical Note
moderateErythromycin + Ibandronate
"Erythromycin may increase the QTc-prolonging activities of Ibandronate."
Clinical Note
moderateErythromycin + Indapamide
Terminal half-life is 1.4-2 hours in adults with normal renal function; may be prolonged to 5-6 hours in anuria.
Primarily hepatic (biliary) excretion of unchanged drug and active metabolites; approximately 15% of an oral dose is excreted unchanged in urine. The remainder is eliminated via feces as unchanged drug and metabolites.
Primarily hepatic (biliary) elimination; approximately 2-5% excreted unchanged in urine, 30-60% excreted in feces via bile.
