ICD-10 Specific code L01: Impetigo

Chlorhexidine is an antimicrobial agent, active against a broad spectrum of Gram-positive and Gram-negative organisms, yeasts, fungi, opportunistic anaerobes and aerobes. Chlorhexidine is mainly a “membrane-acting” agent that destroys the outer membrane of the bacteria. It is inactive on bacterial spores unless the temperatures are high.

Flucloxacillin is an isoxazolyl penicillin of the β-lactam group of antibiotics which exerts a bactericidal effect upon many Gram-positive organisms including β-lactamase-producing staphylococci and streptococci.

Minocycline is a semi-synthetic derivative of tetracycline. Minocycline inhibits protein synthesis in susceptible bacteria. In common with other tetracyclines it is primarily bacteriostatic and has a similar spectrum of activity to other tetracyclines.

Piperacillin is a broad-spectrum, semisynthetic penicillin. Piperacillin exerts bactericidal activity by inhibition of both septum and cell-wall synthesis.

Retapamulin is a semi-synthetic derivative of the compound pleuromutilin, which is isolated through fermentation from Clitopilus passeckerianus. Retapamulin selectively inhibits bacterial protein synthesis by interacting at a unique site on the 50S subunit of the bacterial ribosome that is distinct from the binding sites of other non-pleuromutilin antibacterial agents that interact with the ribosome.

Sultamicillin is the tosylate salt of the double ester of sulbactam plus ampicillin. Sulbactam is a semisynthetic beta-lactamase inhibitor which, in combination with ampicillin, extends the antibacterial activity of the latter to include some beta-lactamase-producing strains of bacteria that would otherwise be resistant.

Ticarcillin disrupts bacterial cell wall development by inhibiting peptidoglycan synthesis and/or by interacting with penicillin-binding proteins.
