Retapamulina
Retapamulina Uses, Dosage, Side Effects, Food Interaction and all others data.
Retapamulina is a semisynthetic derivative of the compound pleuromutilin. In vitro activity of Retapamulina against isolates of Staphylococcus aureus as well as Streptococcus pyogenes has been demonstrated. Retapamulina selectively inhibits bacterial protein synthesis by interacting at a site on the 50S subunit of the bacterial ribosome through an interaction that is different from that of other antibiotics.This binding site involves ribosomal protein L3 and is in the region of the ribosomal P-site and peptidyl transferase center. By virtue of binding to this site, pleuromutilins inhibit peptidyl transfer, block P-site interactions and prevent the normal formation of active 50S ribosomal subunits. Retapamulina demonstrates no in vitro target-specific cross-resistance with other classes of antibiotics.
Retapamulina is a semisynthetic pleuromutilin antibiotic. This drug is usually bacteriostatic in action, but may become bactericidal at highed concentrations (when MBC is 1000 times higher than MIC). Retapamulina acts by selectively inhibiting the initiation of protein synthesis in bacteria at the level of bacterial 50S ribosome.

Uses
Retapamulina ointment is used for the topical treatment of impetigo due to Staphylococcus aureus (methicillin-susceptible isolates only) or Streptococcus pyogenes in patients aged 9 months or older. It is also used to treat infected small lacerations, abrasions or sutured wounds.
Retapamulina is also used to associated treatment for these conditions: Staphylococcal impetigo, Streptococcal impetigo
How Retapamulina works
Retapamulina is a bacterial protein synthesis inhibitor belonging to a class of compounds called pleuromutilins. These compounds inhibit the initiation of protein synthesis by binding to a specific site on the 50S subunit of bacterial ribosome (domain V of 23S rRNA). This binding site involves ribosomal protein L3 and is in the region of the ribosomal P site and peptidyl transferase center. By virtue of binding to this site, pleuromutilins inhibit peptidyl transfer, block P-site interactions, and prevent the normal formation of active 50S ribosomal subunits.
Dosage
Retapamulina dosage
Apply a thin layer of Retapamulina to the affected area (up to 100 cm2 in total area in adults or 2% total body surface area in pediatric patients aged 9 months or older) twice daily for 5 days.
The treated area may be covered with a sterile bandage or gauze dressing if desired.
Side Effects
Side effects: Headache, pyrexia, pruritus, eczema, diarrhoea. Application site irritation, pain, erythema, contact dermatitis.
Adverse effects: Application site irritation (<2% of patients may experience).
Precaution
In the event of sensitization or severe local irritation, usage should be discontinued. Not intended for ingestion or for oral, intranasal, ophthalmic, or intravaginal use.
Interaction
The effect of concurrent application of Retapamulina and other topical products to the same area of skin has not been studied.
