Medication Summary

The goals of pharmacotherapy are to eradicate the infection, to reduce morbidity, and to prevent complications. Various antibiotics are used to treat acrodermatitis chronica atrophicans (ACA).



Class Summary

Empiric antimicrobial therapy for ACA must be comprehensive and should cover all pathogens likely to be present in the context of this clinical setting.

Amoxicillin (Moxatag)

Amoxicillin is bactericidal against Borrelia species. It is a semisynthetic penicillin of the aminopenicillin group that demonstrates a wide spectrum of bactericidal activity related to gram-positive and gram-negative bacteria. Its mechanism of action involves inhibition of

Doxycycline (Vibramycin, Adoxa, Doryx, Monodox)

Doxycycline is a tetracycline antibiotic that inhibits protein synthesis and thus bacterial growth by binding to 30S and possibly 50S ribosomal subunits of susceptible bacteria. It is used for its antibacterial and anti-inflammatory effect and may be considered when there is concern about possible coexistent infection.

Ceftriaxone (Rocephin)

Ceftriaxone is bactericidal against Borrelia species. It is a third-generation cephalosporin with broad-spectrum gram-negative activity. Ceftriaxone has lower efficacy against gram-positive organisms and higher efficacy against resistant organisms. It arrests bacterial growth by binding to 1 or more penicillin-binding proteins.

Cefotaxime (Claforan)

Cefotaxime is a third-generation semisynthetic cephalosporin with broad-spectrum bactericidal activity against gram-negative bacteria and Staphylococcus and Streptococcus species. It is resistant to beta-lactamases. Its mechanism of action is related to inhibition of bacteria cell wall synthesis.

Penicillin G (Pfizerpen)

Penicillin G is a beta-lactam antibiotic. Its mechanism of action is related to inhibition of bacterial cell wall synthesis in the growth phase as a result of penicillin and bacterial transpeptidase binding.
