Excipient information presented when available (limited, particularly for generics); consult specific product labeling.

Suspension Reconstituted, Oral:

Generic: 50 mg/5 mL (50 mL, 100 mL); 100 mg/5 mL (50 mL, 100 mL)

Tablet, Oral:

Generic: 100 mg, 200 mg

Pharmacologic Category

  • Antibiotic, Cephalosporin (Third Generation)

Pharmacology

Inhibits bacterial cell wall synthesis by binding to one or more of the penicillin-binding proteins (PBPs) which in turn inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls, thus inhibiting cell wall biosynthesis. Bacteria eventually lyse due to ongoing activity of cell wall autolytic enzymes (autolysins and murein hydrolases) while cell wall assembly is arrested.

Absorption

Rapid and well absorbed (50%); tablet AUC increased 21% to 33% with food

Distribution

Good tissue penetration, including lung and tonsils; penetrates into pleural fluid

Metabolism

De-esterified in GI tract to active metabolite, cefpodoxime

Excretion

Urine (~29% to 33% as unchanged drug) in 12 hours

Time to Peak

Tablets: Within 2 to 3 hours; Oral suspension: Slower in presence of food, 48% increase in Tmax

Half-Life Elimination

~2 to 3 hours; prolonged with renal impairment (~10 hours for CrCl <30 mL/minute)

Protein Binding

Serum: 22% to 33%; Plasma: 21% to 29%

Special Populations: Renal Function Impairment

Elimination is reduced in those with CrCl less than 50 mL/minute.

Special Populations: Elderly

The half-life is increased to about 4.2 hours.

Use: Labeled Indications

Chronic bronchitis, acute bacterial exacerbation: Treatment of acute bacterial exacerbation of chronic bronchitis caused by Streptococcus pneumoniae, Haemophilus influenzae (non-beta-lactamase-producing strains only), or Moraxella catarrhalis.

Cystitis, acute uncomplicated: Treatment of acute uncomplicated cystitis caused by Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, or Staphylococcus saprophyticus.

Gonorrhea:

Acute, uncomplicated anorectal infections in women: Treatment of acute, uncomplicated anorectal infections in women due to N. gonorrhoeae (including penicillinase-producing strains). Note: Due to issues of resistance, cefpodoxime is no longer recommended for the treatment of acute, uncomplicated anorectal infections in women.

Acute, uncomplicated urethral and cervical: Treatment of acute, uncomplicated urethral and cervical gonorrhea caused by Neisseria gonorrhoeae (including penicillinase-producing strains). Note: Due to issues of resistance, cefpodoxime is no longer recommended for the treatment of acute, uncomplicated urethral and cervical gonorrhea.

Otitis media, acute: Treatment of acute otitis media caused by S. pneumoniae, (excluding penicillin-resistant strains), Streptococcus pyogenes, H. influenzae (including beta-lactamase-producing strains), or M. catarrhalis (including beta-lactamase producing strains).

Pharyngitis or tonsillitis: Treatment of pharyngitis or tonsillitis caused by S. pyogenes.

Pneumonia, community-acquired: Treatment of community-acquired pneumonia caused by S. pneumoniae or H. influenzae (including beta-lactamase-producing strains).

Rhinosinusitis, acute bacterial: Treatment of acute bacterial rhinosinusitis caused by H. influenzae (including beta-lactamase producing strains), S. pneumoniae, and M. catarrhalis. Note: According to the Infectious Diseases Society of America (IDSA) guidelines for acute bacterial rhinosinusitis, cefpodoxime is recommended in combination with clindamycin due to concern for pneumococcal resistance.

Skin and skin structure infections, uncomplicated: Treatment of uncomplicated skin and skin structure infections caused by S. aureus (including penicillinase-producing strains) or S. pyogenes.

Off Label Uses

Urinary tract infections, complicated (including pyelonephritis)

Clinical experience suggests the utility of cefpodoxime as an alternative agent in treatment of acute complicated urinary tract infections (including pyelonephritis) after administration of an appropriate parenteral agent [Hooton 2018b], [Johnson 2018].

Contraindications

Hypersensitivity to cefpodoxime, any component of the formulation, or other cephalosporins

Dosing: Adult

Bronchitis (chronic), bacterial exacerbation: Oral: 200 mg every 12 hours for 10 days

Pneumonia, community acquired: Oral: 200 mg every 12 hours for 14 days. Note: For outpatient empiric therapy in adults, IDSA guidelines recommend use in combination with a macrolide (preferred) or doxycycline and a shortened duration of treatment (ie, minimum of 5 days [patient should be afebrile for ≥48 hours and clinically stable before discontinuation of therapy]) (Mandell 2007).

Rhinosinusitis, acute bacterial (alternative agent for penicillin-allergic patients able to tolerate cephalosporins): Oral: 200 mg every 12 hours (manufacturer's labeling) for 5 to 7 days; if concern for pneumococcal resistance, add clindamycin (IDSA [Chow 2012]; Patel 2018). Note: In uncomplicated acute bacterial rhinosinusitis, initial observation and symptom management without antibiotic therapy is appropriate in most patients (AAO-HNS [Rosenfeld 2015]; Harris 2016).

Skin and skin structure: Oral: 400 mg every 12 hours for 7 to 14 days

Streptococcal pharyngitis (group A) (alternative agent for mild [non-anaphylactic] penicillin allergy): Oral: 100 mg every 12 hours for 5 to 10 days (Pichichero 2018; manufacturer's labeling)

Urinary tract infection (UTI) (alternative agent):

Note: Evidence is limited, but some experts recommend the use of cefpodoxime in this setting. Use with caution and only when recommended agents cannot be used (due to decreased efficacy of oral beta-lactams compared to other agents) (ESMID/IDSA [Gupta 2011]; Hooton 2018a). Closely monitor patient.

Cystitis, acute uncomplicated: Oral: 100 mg twice daily (Hooton 2012; Kavatha 2003) for 5 to 7 days (ESMID/IDSA [Gupta 2011]; Hooton 2018a).

UTI, complicated (including pyelonephritis) (off-label use): Oral: 200 mg twice daily for 10 to 14 days (ESMID/IDSA [Gupta 2011]; Hooton 2018b, Johnson 2018). Note: Oral therapy should follow appropriate parenteral therapy. For outpatient treatment of mild infection, a single dose of a long-acting parenteral agent is acceptable; for outpatients who are more ill or are at risk for more severe illness, consider continuing parenteral therapy until culture and susceptibility results are available (ESMID/IDSA [Gupta 2011]; Hooton 2018b).

Dosing: Geriatric

Refer to adult dosing.

Dosing: Pediatric

General dosing, susceptible infection: Mild to moderate infections: Infants, Children, and Adolescents: Oral: 5 mg/kg/dose every 12 hours; usual maximum dose: 200 mg/dose; however, in patients ≥12 years, higher doses (ie, 400 mg/dose) may be required for some types of infection (Bradley 2015; Red Book [AAP 2015])

Warnings/Precautions

Concerns related to adverse effects:

• Beta-lactam allergy: Use with caution in patients with a history of beta-lactam allergy, especially IgE-mediated reactions (eg, anaphylaxis, angioedema, urticaria).

• 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.

Disease-related concerns:

• Renal impairment: Use with caution in patients with renal impairment; modify dosage in severe impairment.

Concurrent drug therapy issues:

• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Dosage form specific issues:

• Benzyl alcohol and derivatives: Some dosage forms may contain sodium benzoate/benzoic acid; benzoic acid (benzoate) is a metabolite of benzyl alcohol; large amounts of benzyl alcohol (≥99 mg/kg/day) have been associated with a potentially fatal toxicity (“gasping syndrome”) in neonates; the “gasping syndrome” consists of metabolic acidosis, respiratory distress, gasping respirations, CNS dysfunction (including convulsions, intracranial hemorrhage), hypotension, and cardiovascular collapse (AAP ["Inactive" 1997]; CDC 1982); some data suggests that benzoate displaces bilirubin from protein binding sites (Ahlfors 2001); avoid or use dosage forms containing benzyl alcohol derivative with caution in neonates. See manufacturer’s labeling.

Monitoring Parameters

Monitor renal function. Observe for signs and symptoms of anaphylaxis during first dose.
