Abstract:
Doripenem is a new member of the carbapenem class of beta-lactam antibiotics with broad-spectrum coverage of Gram-positive, Gram-negative and anaerobic pathogens similar to imipenem and, especially, meropenem. This parenteral antibiotic may offer slightly more activity than meropenem against selected pathogens, including coverage of some strains of Pseudomonas aeruginosa strains not susceptible to the other antipseudomonal carbapenems. Empiric therapy with doripenem, as with other antipseudomonal carbapenems, may be useful in hospital and intensive care unit settings where multidrug resistance has emerged, especially in Gram-negative enteric pathogens. When P. aeruginosa or multidrug-resistant Gram-positive pathogens such as methicillin-resistant Staphylococcus aureus or vancomycin-resistant enterococci are involved, doripenem must be used in combination. Doripenem has a broad spectrum of activity against many common hospital pathogens, including P. aeruginosa and Burkholderia cepacia, which is similar to meropenem.
Insights
Doripenem is a novel carbapenem antibiotic offering broad-spectrum activity against Gram-positive, Gram-negative, and anaerobic bacteria. It shows potential advantages over meropenem for specific pathogens, including certain Pseudomonas aeruginosa strains.
Area of Science:
- Microbiology
- Pharmacology
- Infectious Diseases
Background:
- Doripenem is a carbapenem antibiotic, a class of beta-lactam antimicrobials.
- It exhibits broad-spectrum activity against Gram-positive, Gram-negative, and anaerobic pathogens.
- Its spectrum is comparable to imipenem and meropenem.
Purpose of the Study:
- To evaluate the spectrum of activity of doripenem.
- To compare doripenem's efficacy against key hospital-acquired pathogens, including multidrug-resistant strains.
- To assess doripenem's potential role in empiric therapy.
Main Methods:
- Antimicrobial susceptibility testing against a range of clinically relevant pathogens.
- Comparative analysis of doripenem's in vitro activity against other carbapenems, particularly meropenem.
- Review of clinical data and guidelines for the use of antipseudomonal carbapenems.
Main Results:
- Doripenem demonstrates broad-spectrum activity, similar to meropenem.
- It may possess enhanced activity against certain Pseudomonas aeruginosa strains resistant to other carbapenems.
- Effective against common hospital pathogens like P. aeruginosa and Burkholderia cepacia.
Conclusions:
- Doripenem is a valuable parenteral antibiotic for treating infections caused by a wide array of bacteria.
- Its potential for improved activity against specific resistant pathogens warrants consideration in empiric treatment strategies.
- Combination therapy may be necessary for infections involving multidrug-resistant Gram-positive pathogens or P. aeruginosa.
