Vantin

Name: Vantin

Pharmacology

Mechanism of Action

Bactericidal against gram-positive and gram-negative bacteria; inhibits bacterial cell-wall synthesis by binding to 1 or more of penicillin-binding proteins; bacteria eventually lyse because activity of cell-wall autolytic enzymes continues while cell-wall assembly is arrested

Absorption

Bioavailability: 50%; acid stable

Peak plasma time: ≤1 hr

Distribution

Distributed well into tissues, including lungs and tonsils; penetrates into pleural fluid

Protein bound: 18-23%

Metabolism

Metabolized in liver to active metabolite

Elimination

Half-life: 2-3 hr; prolonged with renal impairment

Excretion: Urine (80% as unchanged drug) in 24 hr

What is the most important information I should know about Vantin (cefpodoxime)?

Do not take this medication if you are allergic to cefpodoxime, or to similar antibiotics, such as Ceftin, Cefzil, Keflex, Omnicef, and others.

Before taking this medication, tell your doctor if you are allergic to any drugs (especially penicillin). Also tell your doctor if you have kidney disease or a history of intestinal problems.

Take this medication for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated. Cefpodoxime will not treat a viral infection such as the common cold or flu.

Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or has blood in it, call your doctor. Do not use any medicine to stop the diarrhea unless your doctor has told you to.

What should I discuss with my healthcare provider before taking Vantin (cefpodoxime)?

Do not take this medication if you are allergic to cefpodoxime or to other cephalosporin antibiotics, such as:

  • cefaclor (Raniclor);

  • cefadroxil (Duricef);

  • cefazolin (Ancef);

  • cefdinir (Omnicef);

  • cefditoren (Spectracef);

  • cefixime (Suprax);

  • cefprozil (Cefzil);

  • ceftibuten (Cedax);

  • cefuroxime (Ceftin);

  • cephalexin (Keflex); or

  • cephradine (Velosef); and others.

Before taking cefpodoxime, tell your doctor if you are allergic to any drugs (especially penicillins) or if you have:

  • kidney disease (or if you are on dialysis); or

  • a history of intestinal problems, such as colitis.

If you have any of these conditions, you may need a dose adjustment or special tests to safely take this medication.

FDA pregnancy category B. This medication is not expected to be harmful to an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment.

Cefpodoxime passes into breast milk and could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.

Precautions While Using Vantin

If your symptoms or your child's symptoms do not improve within a few days, or if they become worse, check with your doctor.

Cefpodoxime may cause diarrhea, and in some cases it can be severe. Do not take any medicine or give medicine to your child to treat diarrhea without first checking with your doctor. Diarrhea medicines may make the diarrhea worse or make it last longer. If you have any questions about this or if mild diarrhea continues or gets worse, check with your doctor.

Before you or your child have any medical tests, tell the medical doctor in charge that you are using this medicine. The results of some tests may be affected by this medicine.

Susceptibility testing

Dilution Techniques

Quantitative methods are used to determine antimicrobial inhibitory concentrations (MICs). These MICs provide estimates of the susceptibility of microorganisms to antimicrobial compounds. The MICs should be determined using a standardized procedure. Standardized procedures are based on dilution methods1,2 (broth or agar) or equivalent using standardized inoculum concentrations, and standardized concentrations of cefpodoxime from a powder of known potency. The MIC values should be interpreted according to the following criteria:

For Susceptibility Testing of Enterobacteriaceae and Staphylococcus spp.
MIC (mcg/mL) Interpretation
≤2.0 Susceptible (S)
4.0 Intermediate (I)
≥8.0 Resistant (R)
For Susceptibility Testing of Haemophilus spp.*
MIC (mcg/mL) Interpretation†
* The interpretive criteria for Haemophilus spp. is applicable only to broth microdilution susceptibility testing done with Haemophilus Test Medium (HTM) broth.2 † "Intermediate" and "Resistant" categories have not been determined.
≤2.0 Susceptible (S)
For Susceptibility Testing of Neisseria gonorrhoeae.*
MIC (mcg/mL) Interpretation†
* The interpretive value for N. gonorroheae is applicable only to agar dilution susceptibility testing done with Neisseria gonorrhoeae susceptibility test medium.2 † "Intermediate" and "Resistant" categories have not been determined.
≤0.5 Susceptible (S)
For Susceptibility Testing of Streptococcus pneumoniae.
MIC (mcg/mL) Interpretation*
* The interpretive value for S. pneumoniae is applicable only to broth microdilution susceptibility testing done with cation-adjusted Mueller-Hinton broth with lysed horse blood (LHB) (2–5% v/v).2
≤0.5 Susceptible (S)
1.0 Intermediate (I)
≥2.0 Resistant (R)

For Susceptibility Testing of Streptococcus spp. other than Streptococcus pneumoniae.1

A streptococcal isolate that is susceptible to penicillin (MIC ≤0.12 mcg/mL) can be considered susceptible to cefpodoxime for approved indications, and need not be tested against cefpodoxime.

A report of "Susceptible" indicates that the pathogen is likely to be inhibited if the concentration of the antimicrobial compound in the blood reaches usually achievable levels. A report of "Intermediate" indicates that the results should be considered equivocal, and, if the microorganism is not fully susceptible to alternative, clinically feasible drugs, the test should be repeated. This category implies possible clinical applicability in body sites where the drug is physiologically concentrated or in situations where high dosage of drug can be used. This category also provides a buffer zone which prevents small technical factors from causing major discrepancies in interpretation. A report of "Resistant" indicates that the pathogen is not likely to be inhibited if the antimicrobial compound in the blood reaches the concentrations usually achievable; other therapy should be selected.

1 The interpretive value for Streptococcus spp. is applicable only to broth microdilution susceptibility testing done with cation-adjusted Mueller-Hinton broth with lysed horse blood (LHB) (2–5% v/v).2

Quality Control

A standardized susceptibility test procedure requires the use of laboratory control organisms to control the technical aspects of the laboratory procedures. Standard cefpodoxime powder should provide the following MIC values with the indicated quality control strains:

Microorganism (ATCC®#) MIC Range (mcg/mL)
j When susceptibility testing Streptococcus pneumoniae or Streptococcus spp. this quality control strain should be tested.
* These quality control ranges are applicable to tests performed by a broth microdilution procedure using Haemophilus Test Medium (HTM). † These quality control ranges are applicable to tests performed by agar dilution only using GC agar base with 1% defined growth supplement. ‡ These quality control ranges are applicable to tests performed by the broth microdilution method only using cation-adjusted Mueller-Hinton broth with 2 to 5% lysed horse blood.
Escherichia coli (25922) 0.25 – 1.0
Staphylococcus aureus (29213) 1.0 – 8.0
Haemophilus influenzae (49247) 0.25 – 1.0*
Neisseria gonorrhoeae (49226) 0.03 – 0.12†
Streptococcus pneumoniae (49619) 0.03 – 0.12‡
Diffusion Techniques

Quantitative methods that require measurement of zone diameters also provide reproducible estimates of the susceptibility of bacteria to antimicrobial compounds. One such standardized procedure requires the use of standardized inoculum concentrations. This procedure uses paper disks impregnated with 10 mcg cefpodoxime to test the susceptibility of microorganisms to cefpodoxime. Reports from the laboratory providing results of the standard single-disk susceptibility test with a 10 mcg cefpodoxime disk should be interpreted according to the following criteria:

For Susceptibility Testing of Enterobacteriaceae and Staphylococcus spp.
Zone Diameter (mm) Interpretation
≥21 Susceptible (S)
18–20 Intermediate (I)
≤17 Resistant (R)
For Susceptibility Testing of Haemophilus spp.*
Zone Diameter (mm) Interpretation†
* The zone diameter for Haemophilus spp. is applicable only to tests performed on Haemophilus Test Medium (HTM) agar incubated under 5% CO2.2 † "Intermediate" and "Resistant" criteria have not been determined.
≥21 Susceptible (S)
For Susceptibility Testing of Neisseria gonorrhoeae.*
Zone Diameter (mm) Interpretation†
* The zone diameter for N. gonorrhoeae is applicable only to tests performed on GC agar base and 1% defined growth supplement incubated under 5% CO2.2 † "Intermediate" and "Resistant" categories have not been determined.
≥29 Susceptible (S)

For Susceptibility Testing of Streptococcus pneumoniae.2

Isolates of pneumococci with oxacillin zone sizes of ≥20 mm are susceptible (MIC ≤0.06 mcg/mL) to penicillin and can be considered susceptible to cefpodoxime for approved indications, and cefpodoxime need not be tested.

For Susceptibility Testing of Streptococcus spp. other than Streptococcus pneumoniae.3

A streptococcal isolate that is susceptible to penicillin (zone diameter ≥28 mm) can be considered susceptible to cefpodoxime for approved indications, and cefpodoxime need not be tested.

2 The zone diameter for S. pneumoniae is applicable only to tests performed on Mueller-Hinton agar with 5% sheep blood incubated in 5% CO2.2 3 The zone diameter for Streptococcus spp. is applicable only to tests performed on Mueller-Hinton agar with 5% sheep blood incubated in 5% CO2.2

Quality Control

As with standardized dilution techniques, diffusion methods require the use of laboratory control microorganisms that are used to control the technical aspects of the laboratory procedures. For the diffusion technique, the 10 mcg cefpodoxime disk should provide the following zone diameters with the quality control strains listed below:

Microorganism (ATCC®#) Zone Diameter Range (mm)
* This zone diameter range is only applicable to tests performed on Haemophilus Test Medium (HTM) agar incubated in 5% CO2. † This zone diameter range is only applicable to tests performed on GC agar base and 1% defined growth supplement incubated in 5% CO2. ‡ This organism is to be used for quality control testing for both S. pneumoniae and Streptococcus spp. § This zone diameter range is only applicable to tests performed on Mueller-Hinton agar supplemented with 5% defibrinated sheep blood, incubated in 5% CO2.

Film-coated Tablets (Multiple dose)

In clinical trials using multiple doses of cefpodoxime proxetil film-coated tablets, 4696 patients were treated with the recommended dosages of cefpodoxime (100 to 400 mg Q 12 hours). There were no deaths or permanent disabilities thought related to drug toxicity. One-hundred twenty-nine (2.7%) patients discontinued medication due to adverse events thought possibly or probably related to drug toxicity. Ninety-three (52%) of the 178 patients who discontinued therapy (whether thought related to drug therapy or not) did so because of gastrointestinal disturbances, nausea, vomiting, or diarrhea. The percentage of cefpodoxime proxetil-treated patients who discontinued study drug because of adverse events was significantly greater at a dose of 800 mg daily than at a dose of 400 mg daily or at a dose of 200 mg daily.

Patients with Renal Dysfunction

For patients with severe renal impairment (<30 mL/min creatinine clearance), the dosing intervals should be increased to Q 24 hours. In patients maintained on hemodialysis, the dose frequency should be 3 times/week after hemodialysis.

When only the serum creatinine level is available, the following formula (based on sex, weight, and age of the patient) may be used to estimate creatinine clearance (mL/min). For this estimate to be valid, the serum creatinine level should represent a steady state of renal function.

Males:
(mL/min)
Weight (kg) × (140 - age)
72 × serum creatinine (mg/100 mL)
   
Females:
(mL/min)
0.85 × above value
Patients with Cirrhosis

Cefpodoxime pharmacokinetics in cirrhotic patients (with or without ascites) are similar to those in healthy subjects. Dose adjustment is not necessary in this population.
