Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Erythromycin is a macrolide antibiotic that inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, blocking the translocation of peptidyl-tRNA.
Erythromycin ethylsuccinate is a macrolide antibiotic that binds to the 50S subunit of the bacterial ribosome, inhibiting protein synthesis by blocking translocation of peptidyl-tRNA. It may also have anti-inflammatory and immunomodulatory effects.
Apply a thin layer to affected areas twice daily. Topical use only.
400-800 mg orally every 6 hours or 4 times daily; maximum 4 g/day. Intravenous form available but ethylester is oral only.

Terminal elimination half-life is approximately 1.6 hours (range 1.0–2.5 hours) after topical application, too short to accumulate with daily use.
Terminal elimination half-life: 1.5-2 hours in adults with normal renal function; extended to 5-6 hours in patients with severe hepatic impairment; not significantly altered by renal failure.
Primarily hepatic metabolism; less than 10% excreted renally as unchanged drug. Biliary excretion is minimal.
Primarily hepatic metabolism and biliary excretion (80-90% as unchanged drug and metabolites into bile); renal excretion accounts for 5-15% of unchanged drug; fecal elimination of unabsorbed drug.
