Description
Curator's Comment: description was created based on several sources, including: https://www.drugs.com/pro/cefpodoxime-proxetil.html#DOSAGE_AND_ADMINISTRATION | https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=06a35453-8356-4690-aacb-3845cdc84102 | http://www.rxlist.com/vantin-drug.htm

Cefpodoxime is an orally administered, extended spectrum, semi-synthetic antibiotic of the cephalosporin class. Cefpodoxime is a bactericidal agent that acts by inhibition of bacterial cell wall synthesis. Cefpodoxime has activity in the presence of some beta-lactamases, both penicillinases and cephalosporinases, of Gram-negative and Gram-positive bacteria. Cefpodoxime is indicated for the treatment of patients with mild to moderate infections caused by susceptible strains of the designated microorganisms in the conditions: acute otitis media; pharyngitis and/or tonsillitis; community-acquired pneumonia; acute bacterial exacerbation of chronic bronchitis; gonorrhea; uncomplicated skin and skin structure infections; acute maxillary sinusitis and uncomplicated urinary tract infections (cystitis). Common adverse reactions include diarrhea, nausea, vaginal fungal infections, vulvovaginal infections, abdominal pain, headache. Concomitant administration of high doses of antacids (sodium bicarbonate and aluminum hydroxide) or H2 blockers reduces peak plasma levels by 24% to 42% and the extent of absorption by 27% to 32%, respectively. Oral anti-cholinergics (e.g., propantheline) delay peak plasma levels (47% increase in Tmax), but do not affect the extent of absorption (AUC). Probenecid: As with other beta-lactam antibiotics, renal excretion of cefpodoxime was inhibited by probenecid and resulted in an approximately 31% increase in AUC and 20% increase in peak cefpodoxime plasma levels.

CEFPODOXIME PROXETIL

Approved Use

Cefpodoxime proxetil is indicated for the treatment of patients with mild to moderate infections caused by susceptible strains of the designated microorganisms in the conditions listed below. Recommended dosages, durations of therapy, and applicable patient populations vary among these infections. Please see DOSAGE AND ADMINISTRATION for specific recommendations. Acute otitis media caused by Streptococcus pneumoniae (excluding penicillin-resistant strains), Streptococcus pyogenes , Haemophilus influenzae (including beta-lactamase-producing strains), or Moraxella ( Branhamella ) catarrhalis (including beta-lactamase-producing strains). Pharyngitis and/or tonsillitis caused by Streptococcus pyogenes . NOTE: Only penicillin by the intramuscular route of administration has been shown to be effective in the prophylaxis of rheumatic fever. Cefpodoxime proxetil is generally effective in the eradication of streptococci from the oropharynx. However, data establishing the efficacy of cefpodoxime proxetil for the prophylaxis of subsequent rheumatic fever are not available. Community-acquired pneumonia caused by S. pneumoniae or H. Influenzae (including beta-lactamase-producing strains). Acute bacterial exacerbation of chronic bronchitis caused by S. pneumoniae , H. influenzae (non-beta-lactamase-producing strains only), or M. catarrhalis. Data are insufficient at this time to establish efficacy in patients with acute bacterial exacerbations of chronic bronchitis caused by beta-lactamase-producing strains of H. influenzae . Acute, uncomplicated urethral and cervical gonorrhea caused by Neisseria gonorrhoeae (including penicillinase-producing strains). Acute, uncomplicated ano -rectal infections in women due to Neisseria gonorrhoeae (including penicillinase-producing strains). NOTE: The efficacy of cefpodoxime in treating male patients with rectal infections caused by N. gonorrhoeae has not been established. Data do not support the use of cefpodoxime proxetil in the treatment of pharyngeal infections due to N. gonorrhoeae in men or women. Uncomplicated skin and skin structure infections caused by Staphylococcus aureus (including penicillinase-producing strains) or Streptococcus pyogenes . Abscesses should be surgically drained as clinically indicated. NOTE: In clinical trials, successful treatment of uncomplicated skin and skin structure infections was dose-related. The effective therapeutic dose for skin infections was higher than those used in other recommended indications. (See DOSAGE AND ADMINISTRATION.) Acute maxillary sinusitis caused by Haemophilus influenzae (including beta-lactamase-producing strains), Streptococcus pneumoniae , and Moraxella catarrhalis . Uncomplicated urinary tract infections (cystitis) caused by Escherichia coli, Klebsiella pneumoniae , Proteus mirabilis, or Staphylococcus saprophyticus . NOTE: In considering the use of cefpodoxime proxetil in the treatment of cystitis, cefpodoxime proxetil’s lower bacterial eradication rates should be weighed against the increased eradication rates and different safety profiles of some other classes of approved agents. (See CLINICAL STUDIES section.) Appropriate specimens for bacteriological examination should be obtained in order to isolate and identify causative organisms and to determine their susceptibility to cefpodoxime. Therapy may be instituted while awaiting the results of these studies. Once these results become available, antimicrobial therapy should be adjusted accordingly. To reduce the development of drug-resistant bacteria and maintain the effectiveness of Cefpodoxime Proxetil for Oral Suspension, USP and other antibacterial drugs, Cefpodoxime Proxetil for Oral Suspension, USP should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

Acute maxillary sinusitis caused by Haemophilus influenzae (including beta-lactamase-producing strains), Streptococcus pneumoniae , and Moraxella catarrhalis . Uncomplicated urinary tract infections (cystitis) caused by Escherichia coli, Klebsiella pneumoniae , Proteus mirabilis, or Staphylococcus saprophyticus . NOTE: In considering the use of cefpodoxime proxetil in the treatment of cystitis, cefpodoxime proxetil’s lower bacterial eradication rates should be weighed against the increased eradication rates and different safety profiles of some other classes of approved agents. (See CLINICAL STUDIES section.) Appropriate specimens for bacteriological examination should be obtained in order to isolate and identify causative organisms and to determine their susceptibility to cefpodoxime. Therapy may be instituted while awaiting the results of these studies. Once these results become available, antimicrobial therapy should be adjusted accordingly. To reduce the development of drug-resistant bacteria and maintain the effectiveness of Cefpodoxime Proxetil for Oral Suspension, USP and other antibacterial drugs, Cefpodoxime Proxetil for Oral Suspension, USP should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

Cefpodoxime proxetil is indicated for the treatment of patients with mild to moderate infections caused by susceptible strains of the designated microorganisms in the conditions listed below. Recommended dosages, durations of therapy, and applicable patient populations vary among these infections. Please see DOSAGE AND ADMINISTRATION for specific recommendations. Acute otitis media caused by Streptococcus pneumoniae (excluding penicillin-resistant strains), Streptococcus pyogenes , Haemophilus influenzae (including beta-lactamase-producing strains), or Moraxella ( Branhamella ) catarrhalis (including beta-lactamase-producing strains). Pharyngitis and/or tonsillitis caused by Streptococcus pyogenes . NOTE: Only penicillin by the intramuscular route of administration has been shown to be effective in the prophylaxis of rheumatic fever. Cefpodoxime proxetil is generally effective in the eradication of streptococci from the oropharynx. However, data establishing the efficacy of cefpodoxime proxetil for the prophylaxis of subsequent rheumatic fever are not available. Community-acquired pneumonia caused by S. pneumoniae or H. Influenzae (including beta-lactamase-producing strains). Acute bacterial exacerbation of chronic bronchitis caused by S. pneumoniae , H. influenzae (non-beta-lactamase-producing strains only), or M. catarrhalis.

Route of Administration: Oral
In Vitro Use Guide
The in-vitro activity of cefpodoxime was studied in 529 clinical isolates and compared with the activity of other oral beta-lactams. Amongst the Enterobacteriaceae cefpodoxime was very active (MIC90 less than or equal to 1 mg/l--other than genera commonly possessing chromosomal beta-lactamases). Against these strains cefpodoxime was comparable in activity to cefixime and about eight-fold more active than cefuroxime and 8-16-fold more active than cefaclor and cephalexin. Staphylococcus aureus strains were moderately susceptible (MIC90 4 mg/l) to cefpodoxime.
