Area of Science:

  • Infectious Diseases
  • Microbiology
  • Pharmacology

Background:

  • Beta-lactam antibiotics, including third-generation cephalosporins, face reduced efficacy due to widespread beta-lactamase-mediated resistance.
  • Carbapenems, such as meropenem and imipenem/cilastatin, exhibit broad-spectrum activity against major Gram-positive and Gram-negative pathogens.

Purpose of the Study:

  • To evaluate the efficacy and safety of meropenem compared to other antibiotic regimens.
  • To highlight meropenem's advantages over imipenem/cilastatin, particularly its stability and activity spectrum.

Main Methods:

  • Comparative clinical trials assessing meropenem monotherapy versus combination therapies for nosocomial respiratory tract and intra-abdominal infections.
  • Assessment of meropenem's stability against various beta-lactamases and its pharmacokinetic profile, including central nervous system penetration.

Main Results:

  • Meropenem monotherapy demonstrated clinical efficacy rates exceeding 75% in nosocomial respiratory tract infections, comparable to ceftazidime plus aminoglycoside.
  • In intra-abdominal infections, meropenem showed efficacy equivalent to clindamycin plus tobramycin and imipenem/cilastatin.
  • Meropenem exhibits superior stability to serine beta-lactamases and enhanced activity against Gram-negative bacteria, including Pseudomonas aeruginosa.

Conclusions:

  • Meropenem is a highly effective carbapenem antibiotic with broad-spectrum activity and excellent stability against beta-lactamases.
  • Meropenem offers advantages over imipenem/cilastatin and is a suitable monotherapy option for complex infections, including meningitis.
