Abstract:
Panipenem is a parenteral carbapenem antibacterial agent with a broad spectrum of in vitro activity covering a wide range of Gram-negative and Gram-positive aerobic and anaerobic bacteria, including Streptococcus pneumoniae and species producing beta-lactamases. Panipenem is coadministered with betamipron to inhibit panipenem uptake into the renal tubule and prevent nephrotoxicity. In large, randomised clinical trials, panipenem/betamipron demonstrated good clinical and bacteriological efficacy (similar to that of imipenem/cilastatin) in adults with respiratory tract or urinary tract infections. Panipenem/betamipron was also effective in adults with surgical or gynaecological infections, and in paediatric patients with respiratory tract and urinary tract infections in noncomparative trials. In small trials in elderly patients reported as abstracts, panipenem/betamipron demonstrated clinical efficacy similar to intravenous piperacillin and greater than oral ofloxacin in urinary tract infections. Elderly patients with respiratory tract infections also responded to therapy. Panipenem/betamipron is well tolerated with few adverse events reported in clinical trials, most commonly elevated serum levels of hepatic transaminases and eosinophils, rash and diarrhoea.
Insights
Panipenem/betamipron is an effective parenteral carbapenem antibiotic for various infections, demonstrating good clinical and bacteriological outcomes. This combination therapy showed favorable tolerability with minimal adverse events in diverse patient populations.
Area of Science:
- Pharmacology
- Infectious Diseases
- Clinical Medicine
Background:
- Panipenem is a parenteral carbapenem antibiotic with broad-spectrum activity against Gram-negative and Gram-positive bacteria.
- It is administered with betamipron to prevent nephrotoxicity by inhibiting renal tubule uptake.
- The combination targets infections caused by beta-lactamase-producing bacteria and Streptococcus pneumoniae.
Purpose of the Study:
- To evaluate the clinical and bacteriological efficacy of panipenem/betamipron.
- To assess the safety and tolerability of panipenem/betamipron in various patient groups.
- To compare panipenem/betamipron with other antibiotics in specific patient populations.
Main Methods:
- Large, randomized clinical trials in adults with respiratory and urinary tract infections.
- Non-comparative trials in adults with surgical/gynecological infections and pediatric patients.
- Small trials in elderly patients comparing efficacy against piperacillin and ofloxacin.
Main Results:
- Panipenem/betamipron demonstrated good clinical and bacteriological efficacy, comparable to imipenem/cilastatin.
- Effective in treating respiratory, urinary, surgical, and gynecological infections in adults.
- Showed efficacy in pediatric patients and elderly patients with urinary and respiratory tract infections.
Conclusions:
- Panipenem/betamipron is a clinically effective and well-tolerated treatment option for a wide range of bacterial infections.
- Its efficacy is comparable to established treatments like imipenem/cilastatin.
- The combination therapy presents a favorable safety profile with generally mild adverse events.
