- Antibiotic, Pleuromutilin
- Antibiotic, Topical
Primarily bacteriostatic; inhibits normal bacterial protein biosynthesis by binding at a unique site (protein L3) on the ribosomal 50S subunit; prevents formation of active 50S ribosomal subunits by inhibiting peptidyl transfer and blocking P-site interactions at this site
Topical: Low; increased when applied to abraded skin; age dependent; absorption highest in younger patients.
Infants and Children 2 to 24 months: In patients receiving twice-daily retapamulin, 46% of subjects 2 to 24 months of age had a measurable serum concentration compared to 7% of those ≥2 years. A higher proportion of infants 2 to 9 months had measurable serum concentration as compared to infants and children 9 to 24 months (69% vs 32%).
Children ≥ 2 years, Adolescents, and Adults: Low; increased when applied to abraded skin.
Hepatic via CYP 3A4; extensively metabolized by mono-oxygenation and di-oxygenation to multiple metabolites
Use: Labeled Indications
Impetigo: Treatment of impetigo due to Staphylococcus aureus (methicillin-susceptible isolates only) or Streptococcus pyogenes in adults and pediatric patients 9 months and older.
There are no contraindications listed in the manufacturer's labeling.
Impetigo: Topical: Apply a thin layer to affected area twice daily for 5 days (maximum; total treatment area should not exceed 100 cm2 total body surface area).
Refer to adult dosing.
Impetigo: Note: For patients with a limited number of lesions (IDSA [Stevens 2014]); total treatment area should not exceed 2% of total body surface area or 100 cm2 total body surface area, whichever is less.
Infants <9 months: Limited data available: Topical: Apply thin layer to lesions twice daily for 5 days (IDSA [Stevens 2014]); Note: In trials, infants 2 to 9 months of age had higher systemic exposure than older pediatric patients; monitor closely for systemic effects.
Infants ≥9 months, Children, and Adolescents: Topical: Apply thin layer to affected area (lesions) twice daily for 5 days (IDSA [Stevens 2014]; manufacturer's labeling).
Topical: For external use only; not for intranasal, intravaginal, ophthalmic, oral, or mucosal application. May cover treatment area with sterile bandage or gauze dressing if needed. Wash hands after application if the hands are not the area for treatment.
Store at 25°C (77°F); excursions permitted between 15°C and 30°C (59°F and 86°F).
CYP3A4 Inhibitors (Strong): May increase the serum concentration of Retapamulin. Management: Avoid this combination in patients less than 2 years old. No action is required in other populations. Monitor therapy

Central nervous system: Headache (1% to 2%)
Dermatologic: Eczema (infants, children & adolescents: 1%)

Concerns related to adverse effects:
• Skin irritation: If sensitization or severe local skin irritation occurs, wipe ointment off and discontinue use.
• Superinfection: Prolonged use may result in fungal or bacterial superinfection, including C. difficile-associated diarrhea (CDAD) and pseudomembranous colitis; CDAD has been observed >2 months postantibiotic treatment.
• Appropriate use: For external use only; not for intranasal, intravaginal, ophthalmic, oral, or mucosal application. Concomitant use with other topical products to the same treatment area has not been evaluated.
Retapamulin has limited systemic absorption following topical administration. Use during pregnancy is not expected to result in significant exposure to the fetus.
