Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Retapamulin is a pleuromutilin antibiotic that selectively inhibits bacterial protein synthesis by interacting with the 50S ribosomal subunit, specifically at the L3 ribosomal protein and the peptidyl transferase center, thereby preventing peptide bond formation.
Erythromycin is a macrolide antibiotic that binds to the 50S subunit of the bacterial ribosome, inhibiting protein synthesis by blocking the translocation step. It also has anti-inflammatory and immunomodulatory effects, including inhibition of neutrophil chemotaxis and modulation of cytokine production.
1% ointment applied topically to affected area twice daily for 5 days. Total treatment area should not exceed 100 cm². Maximum single dose is 0.5 g per 100 cm².
Topical application of a thin layer to affected area twice daily; oral administration not applicable.

Terminal half-life is approximately 11-14 hours in adults after topical application, supporting twice-daily dosing.
Terminal elimination half-life: 1.5–2.0 hours in adults with normal renal function, prolonged in renal impairment (up to 6–8 hours with GFR <30 mL/min).
Retapamulin is primarily eliminated via the fecal route (96.5% of dose), with minimal renal excretion (<0.5% of dose).
Almost entirely renal (90-95% as unchanged drug via glomerular filtration and tubular secretion), with less than 5% fecal or biliary elimination.
