Cefaclor AF: correlation of microbiology and clinical outcome
1Institute for Microbiologic Research, Franklin, TN 37064.
Abstract:
Cefaclor is active against Haemophilus influenzae and Moraxella catarrhalis in addition to the pathogens typically susceptible to first-generation cephalosporins. Cefaclor advanced formulation (cefaclor AF) provides the opportunity for once or twice daily dosing of this agent. Clinical trials using cefaclor AF have been carried out in a number of centres on bacterial infections of the respiratory tract, the urinary tract and the skin. In vitro susceptibility tests on selected pathogens from the clinical trials were carried out according to National Committee for Clinical Laboratory Standards recommendations, generally with excellent agreement between in vitro and in vivo response.
Insights
Cefaclor advanced formulation (cefaclor AF) offers effective treatment for bacterial infections, including respiratory, urinary, and skin conditions. Clinical trials showed excellent agreement between laboratory susceptibility tests and patient responses to cefaclor AF.
Area of Science:
- Microbiology
- Pharmacology
- Infectious Diseases
Background:
- Cefaclor exhibits activity against common respiratory pathogens like Haemophilus influenzae and Moraxella catarrhalis.
- First-generation cephalosporins typically target a range of susceptible bacterial pathogens.
- Advanced formulations aim to improve drug delivery and patient compliance.
Purpose of the Study:
- To evaluate the efficacy of cefaclor advanced formulation (cefaclor AF) in treating bacterial infections.
- To assess the antimicrobial spectrum of cefaclor, including activity against specific respiratory pathogens.
- To correlate in vitro antimicrobial susceptibility data with clinical outcomes in patients treated with cefaclor AF.
Main Methods:
- Clinical trials were conducted across multiple centers to assess cefaclor AF in respiratory, urinary, and skin infections.
- In vitro susceptibility testing was performed on selected bacterial pathogens isolated from clinical trial participants.
- Testing followed National Committee for Clinical Laboratory Standards (NCCLS) guidelines.
Main Results:
- Cefaclor AF demonstrated activity against Haemophilus influenzae and Moraxella catarrhalis.
- Clinical trials investigated cefaclor AF for various bacterial infections.
- In vitro susceptibility results generally showed excellent agreement with in vivo clinical responses.
Conclusions:
- Cefaclor AF is a viable therapeutic option for bacterial infections caused by susceptible pathogens.
- The advanced formulation of cefaclor allows for convenient once or twice daily dosing.
- The correlation between in vitro susceptibility and in vivo efficacy supports the use of cefaclor AF.
