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.
Elase-Chloromycetin is a combination product containing fibrinolysin and desoxyribonuclease (Elase) for enzymatic debridement, and chloramphenicol (Chloromycetin), a bacteriostatic antibiotic that inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit.
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: Apply thin layer to affected area 2-3 times daily.

Terminal half-life is approximately 11-14 hours in adults after topical application, supporting twice-daily dosing.
Chloramphenicol has a terminal elimination half-life of 1.5 to 4.0 hours in adults with normal renal and hepatic function. In neonates, half-life can be prolonged to 24-48 hours, necessitating dose adjustment. Elase has no systemic half-life as it acts locally.
Retapamulin is primarily eliminated via the fecal route (96.5% of dose), with minimal renal excretion (<0.5% of dose).
Chloramphenicol is primarily excreted renally (approximately 90% as inactive metabolites). Fecal excretion accounts for less than 1% of the dose. Biliary elimination is negligible. Elase (fibrinolysin and desoxyribonuclease) is locally degraded and not systemically absorbed, thus its excretion is irrelevant.
