Dose and Dosage:
- The typical dose of cefpodoxime for adults ranges from 100 mg to 400 mg, taken orally once or twice daily.
- The dosage may vary depending on the type and severity of the infection being treated.
Frequency:
- Cefpodoxime is usually taken once or twice daily, depending on the severity of the infection and the prescribing physician’s instructions.
Route of Administration (ROA):
- Cefpodoxime is administered orally in the form of tablets or suspension.
Mechanism of Action (MOA):
- Cefpodoxime is a third-generation cephalosporin antibiotic that works by inhibiting bacterial cell wall synthesis, leading to the eventual death of susceptible bacteria.
Pharmacokinetics (PK):
- Cefpodoxime is well absorbed after oral administration, with peak plasma concentrations reached within 2 to 3 hours.
- It has a bioavailability of approximately 50% and can be taken with or without food.
- The elimination half-life of cefpodoxime is approximately 2 hours in adults.
Pharmacodynamics (PD):
- Cefpodoxime exhibits bactericidal activity against a wide range of gram-positive and gram-negative bacteria by interfering with cell wall synthesis.
Pathophysiology:
- Cefpodoxime acts by binding to penicillin-binding proteins (PBPs) on the bacterial cell wall, inhibiting the final transpeptidation step of peptidoglycan synthesis.
Indications:
- Cefpodoxime is indicated for the treatment of various bacterial infections, including respiratory tract infections, urinary tract infections, skin and soft tissue infections, and certain sexually transmitted infections such as gonorrhea.
Contraindications:
- Cefpodoxime is contraindicated in patients with a known allergy to cephalosporin antibiotics or any component of the formulation.
- It should be used with caution in patients with a history of allergic reactions to penicillins or other beta-lactam antibiotics.
Drug Interactions:
- Cefpodoxime may interact with certain medications, including probenecid, which can increase the concentration of cefpodoxime in the body by reducing renal clearance.
- Concomitant use of cefpodoxime with nephrotoxic drugs may increase the risk of kidney damage.
Monitoring and Laboratory Tests:
- Monitoring of renal function, especially in patients with pre-existing kidney disease or those receiving high doses of cefpodoxime, may be warranted.
- Laboratory tests, including complete blood count (CBC) and renal function tests, may be performed periodically during treatment to monitor for any adverse effects.
