Adult inpatients and outpatients with a diagnosis of community-acquired bacterial pneumonia were evaluated in 2 pivotal clinical studies In the first study, 590 patients were enrolled in a prospective, multicenter, unblinded randomized trial comparing levofloxacin 500 mg once daily orally or intravenously for 7 to 14 days to ceftriaxone 1 to 2 grams intravenously once or in equally divided doses twice daily followed by cefuroxime axetil 500 mg orally twice daily for a total of 7 to 14 days
A good step-down antibiotic for Ceftriaxone IV is Levofloxacin (PO), as it has been compared to a regimen of ceftriaxone followed by cefuroxime axetil in a clinical study for the treatment of community-acquired bacterial pneumonia 1.
- Key points:
- Levofloxacin 500 mg once daily orally or intravenously for 7 to 14 days was compared to ceftriaxone 1 to 2 grams intravenously once or in equally divided doses twice daily followed by cefuroxime axetil 500 mg orally twice daily for a total of 7 to 14 days.
- Clinical success (cure plus improvement) with levofloxacin at 5 to 7 days posttherapy was superior (95%) to the control group (83%).
From the Research
Cefpodoxime is a suitable step-down oral antibiotic from intravenous ceftriaxone, particularly for respiratory infections, due to its broad spectrum of activity and convenience of twice-daily administration 2. When considering a step-down antibiotic from intravenous ceftriaxone, the goal is to select an oral agent that provides similar coverage but with the convenience of oral administration, once the patient's condition has stabilized.
- Key factors in choosing a step-down antibiotic include the type of infection being treated, the susceptibility of the causative pathogens, and the patient's ability to take oral medications.
- For respiratory infections, cefpodoxime (200 mg twice daily) is an appropriate option due to its efficacy against common respiratory pathogens, including Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis 2.
- The duration of oral therapy should complete the total intended treatment course that was started with ceftriaxone, ensuring that the infection is fully treated to prevent relapse or resistance development.
- Patients should be clinically improving, with resolved fever for at least 24 hours, have a functioning gastrointestinal tract, and be able to take oral medications before transitioning from IV to oral therapy.
- Cefpodoxime proxetil has been evaluated for use in cost-containment programs as step-down therapy in community-acquired pneumonia and as abbreviated therapy in upper respiratory tract infections, showing potential for reducing hospitalization costs and improving patient outcomes 3.
- It's worth noting that while cefdinir and amoxicillin-clavulanate are also options for step-down therapy, cefpodoxime's broad spectrum of activity, convenience, and pharmacoeconomic benefits make it a preferred choice for certain infections 2, 3.
