Amoxicillin, amoxicillin/clavulanate, and cefuroxime axetil are the PO drugs of choice for the common extracellular bacteria that cause sinopulmonary infections. Ceftriaxone administered intravenously is the first-line antibiotic for suspected bacteremia or sepsis and for pneumonia. It covers penicillin-resistant pneumococci. Intramuscular administration is avoided because of bleeding caused by thrombocytopenia. Nafcillin is chosen for invasive S aureus. Vancomycin is needed for penicillin-allergic patients and for treatment of methicillin-resistant S aureus. Vancomycin-resistant S aureus, GISA, may require fluoroquinolones, linezolid or Synercid.

Prophylactic antibiotics for patients with splenectomies are penicillin or amoxicillin; a macrolide can be used for penicillin-allergic patients.

Amoxicillin (Trimox, Amoxil, Biomox)

Interferes with synthesis of cell wall mucopeptides during active multiplication, resulting in bactericidal activity against susceptible bacteria.

Amoxicillin/clavulanate (Augmentin)

Drug combination treats bacteria resistant to beta-lactam antibiotics.

For children >3 mo, base dosing protocol on amoxicillin content. Because of different amoxicillin–clavulanic acid ratios in 250-mg tab (250/125) vs 250-mg tab (250/62.5), do not use 250-mg tab until child weighs >40 kg.

Cefuroxime axetil (Ceftin)

Second-generation cephalosporin maintains gram-positive activity that first-generation cephalosporins have. Adds activity against Proteus mirabilis, H influenzae, E coli, K pneumoniae, and Moraxella catarrhalis.

Ceftriaxone (Rocephin)

Third-generation cephalosporin with broad-spectrum activity; efficacy against resistant organisms. Arrests bacterial growth by binding to one or more penicillin-binding proteins.

Vancomycin (Lyphocin, Vancocin, Vancoled)

Potent antibiotic directed against gram-positive organisms and active against Enterococcus species. Indicated for patients who cannot receive or who have not responded to penicillins and cephalosporins or who have infections with resistant staphylococci.

To avoid toxicity, current recommendation is to assay vancomycin trough levels after third dose drawn 0.5 h before next dosing. Use creatinine clearance to adjust dose in patients with renal impairment.


DOC for acute pneumonia and deep-seated abscesses caused by S aureus.
