Antibacterials for systemic use
CEFDEE is an orally administered, extended-spectrum, semi-synthetic antibiotic of the third generation cephalosporins. It exerts bactericidal action on beta lactamase producing microorganisms that are resistant to penicillins and cephalosporins. The drug has a broad spectrum of antibacterial activity encompassing both Gram-negative and Gram-positive bacteria.
Mechanism of Action:
CEFDEE acts by inhibition of bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) located in the bacterial cytoplasmic membrane. It is stable in the presence of some beta-lactamases, both penicillinases and cephalosporinases, of Gram-positive and Gram-negative bacteria. It is inactivated by certain extended-spectrum beta-lactamases.
Cefpodoxime is active against the following bacteria, both in vitro and in clinical infections
- Staphylococcus aureus (methicillin-susceptible strains, including those pro- ducing penicillinases)
- Staphylococcus saprophyticus Streptococcus pneumoniae (excluding penicillin-resistant isolates)
- Streptococcus pyogenes
- Escherichia coli
- Klebsiella pneumonia
- Proteus mirabilis
- Haemophilus influenzae (including beta-lactamase producing isolates)
- Moraxella catarrhalis
- Neisseria gonorrhoeae (including penicillinase-producing isolates)
Absorption and Excretion:
Cefpodoxime proxetil is a prodrug that is absorbed from the intestinal mucosa and de-esterified to its active metabolite, cefpodoxime. Following oral administration of 100 mg of cefpodoxime proxetil to fasting subjects, approximately 50% of the administered cefpodoxime dose was absorbed systemically. Absorption is enhanced by concomitant administration of food. Pretreatment with antacids or H2-receptor antagonists that raises gastric pH results in reduced absorption. Over the recommended dosing range (100 to 400 mg), after single and multiple-dose (12-hourly) administration of cefpodoxime proxetil, average peak plasma concentrations of cefpodoxime range from 1.0 to 4.5 mg/L and occur between 1.9 and 3.1 hours after administration. The half-life of cefpodoxime ranges from 1.9 to 2.8 hours.
There is minimal metabolism of cefpodoxime in vivo. Fraction not absorbed is degraded in the gastrointestinal tract and excreted in the feces. It is eliminated primarily by renal excretion. Over the recommended dosing range (100 to 400 mg), approximately 29 to 33% of the administered cefpodoxime dose is excreted unchanged in the urine in 12 hours time period. In patients with impaired renal function the disposition of cefpodoxime is altered.
Distribution: Low protein binding of cefpodoxime readily transfers it across the capillary lining into tissues.
Cefpodoxime levels in skin blister fluid at 12 hours for the 200 mg and 400 mg multiple-dose regimens, reaches 0.2 and 0.4 mcg/mL, respectively.
Following multiple-dose administration every 12 hours for 5 days of 200 mg or 400 mg cefpodoxime proxetil, the mean maximum cefpodoxime concentration in skin blister fluid reaches 1.6 and 2.8 mcg/mL, respectively.
Following a single, oral 100 mg dosing, the mean maximum cefpodoxime concentration in tonsil tissue averaged 0.24 mcg/g at 4 hours post-dosing and 0.09 mcg/g at 7 hours post-dosing. No detection of cefpodoxime in tonsillar tissue was reported 12 hours after dosing. Concentrations of cefpodoxime exceeded the MIC 90 of S. pyogenes for at least 7 hours after dosing of 100 mg of cefpodoxime proxetil.
Following a single, oral 200 mg dosing, the mean maximum cefpodoxime concentration in lung tissue averaged 0.63 mcg/g at 3 hours post dosing, 0.52 mcg/g at 6 hours post dosing, and 0.19 mcg/g at 12 hours post-dosing. Cefpodoxime penetrated into lung tissue and produced sustained drug concentrations for at least 12 hours after dosing at levels that exceeded the MIC 90 for S. pneumoniae and H. influenzae.

CEFDEE is safe to be used in Geriatric patients. Dose adjustment in elderly patients with normal renal function is not necessary.
Patients with Renal Dysfunction
In patients with moderate (30 to 49 mL/min creatinine clearance) or severe renal impairment (5 to 29 mL/min creatinine clearance), the half-life increased to 5.9 and 9.8 hours respectively.
Therefore for patients with severe renal impairment the dosing intervals should be increased Q 24hours. In patients maintained on hemodialysis, dose frequency should be 3times/week after hemodialysis.
Patients with Cirrhosis:
Directions for use:
Disperse the tablet in teaspoonful of boiled and cooled water immediately before administration.
CEFDEE is contraindicated in patients with a known allergy to cefpodoxime or to the cephalosporin group of antibiotics.
If CEFDEE is to be administered to penicillin sensitive patients, caution should be exercised because cross hypersensitivity among beta-lactam antibiotics.
Common side effects seen with CEFDEE: Diarrhea and nausea/vomiting
Uncommon side effects: dizziness, headache, syncope, rash, abdominal pain.
Inform your physician if you experience any side effects.
Warnings and Precautions:
- CEFDEE should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria to maintain efficacy and to prevent the development of drug resistant strains.
- Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including cefpodoxime proxetil and may cause mild diarrhea to fatal colitis. If CDAD is suspected or confirmed, ongoing antibiotic being used not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. difficile, and surgical evaluation should be clinically indicated.
The following drugs are known for having drug interactions with cefpodoxime proxetil:
- Oral anticholinergics
- Nephrotoxic drugs
Pregnancy category: B
CEFDEE should be used during pregnancy only if clearly needed.
Cefpodoxime is excreted in human milk. There is risk for serious reactions in nursing infants, so a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Safety and efficacy in infants less than 2 months of age have not been established
Information to be shared with Patients:
Antibacterial drugs including CEFDEE should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When CEFDEE is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may
(1) Decrease the effectiveness of the immediate treatment and
(2) Increase the likelihood that bacteria will develop resistance and will not be treatable by CEFDEE or other antibacterial drugs in the future.
Diarrhea is a common problem caused by antibiotics which usually ends when the antibiotic is discontinued. Sometimes after starting treatment with antibiotics, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as two or more months after having taken the last dose of the antibiotic. If this occurs, patients should contact their physician immediately.
