Brand Names: U.S.
- 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: Overall, in trials, 46% of subjects 2 to 24 months of age had measurable serum concentration compared to 7% of those ≥2 years. Within the 2 to 24 month age group, the aggregate of infants 2 to 9 months had a higher proportion of patients with measurable serum concentration than those aged 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: Infants ≥9 months, Children, and Adolescents: Topical: Apply a thin layer to affected area twice daily for 5 days (maximum: Total treatment area should not exceed 2% of total body surface area).
Dosing: Renal Impairment
There are no dosage adjustments provided in the manufacturer's labeling. However, dosage adjustment unlikely due to low systemic absorption.
Dosing: Hepatic Impairment
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.
Pregnancy Risk Factor
Adverse events have not been observed in animal reproduction studies.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Have patient report immediately to prescriber burning, redness, severe skin irritation, edema, oozing, bleeding, or skin sores (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.

This information is intended to serve as a concise initial reference for health care professionals to use when discussing medications with a patient.
