Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to the 50S ribosomal subunit, inhibiting bacterial protein synthesis by blocking the translocation step.
Aminoglycoside antibiotic that binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibiting bacterial protein synthesis.
250-500 mg orally every 6 hours or 500-1000 mg intravenously every 6 hours; maximum 4 g/day.
500 mg intramuscularly or intravenously every 12 hours; or 1 gram every 24 hours for severe infections.

Terminal half-life is 1.4-2 hours in adults with normal renal function; may be prolonged to 5-6 hours in anuria.
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
2.5 hours (increased to 5-8 hours in neonates and up to 24-48 hours in anuria).
Primarily hepatic (biliary) elimination; approximately 2-5% excreted unchanged in urine, 30-60% excreted in feces via bile.
Primarily renal (60-80% unchanged) via glomerular filtration; biliary/fecal <5%.
