Clinical evaluation of piperacillin therapy for infection
Abstract:
Piperacillin sodium, a semisynthetic penicillin that inhibits many Klebsiella and Pseudomonas aeruginosa organisms resistant to carbenicillin, was used to treat 41 episodes of infection in 35 patients. Infectious sites included lungs, urinary tract, and tissue, including peritonitis. Seven patients had bacteremia. Clinical and bacteriological cures were achieved in 85% of infections. Cure was achieved with piperacillin in patients infected with carbenicillin-resistant P aeruginosa and Klebsiella organisms. Adverse effects were minor and included rash in two patients. Serum levels were easily maintained above the inhibitory levels for susceptible organisms. Piperacillin was a safe, well-tolerated, and effective antimicrobial agent.
Insights
Piperacillin sodium effectively treated various infections, including those caused by carbenicillin-resistant bacteria like Klebsiella and Pseudomonas aeruginosa. This safe and well-tolerated antibiotic achieved high cure rates with minor adverse effects.
Area of Science:
- Infectious Diseases
- Pharmacology
- Microbiology
Background:
- Carbenicillin resistance in Klebsiella and Pseudomonas aeruginosa poses a clinical challenge.
- Piperacillin is a semisynthetic penicillin with a broader spectrum of activity.
Purpose of the Study:
- To evaluate the efficacy and safety of piperacillin sodium in treating diverse bacterial infections.
- To assess piperacillin's effectiveness against carbenicillin-resistant Gram-negative organisms.
Main Methods:
- A clinical study involving 35 patients with 41 infection episodes.
- Treatment with piperacillin sodium for infections of the lungs, urinary tract, tissue, and peritonitis.
- Monitoring of clinical and bacteriological outcomes, adverse effects, and serum drug levels.
Main Results:
- An 85% clinical and bacteriological cure rate was achieved across all infection types.
- Piperacillin demonstrated efficacy in treating infections caused by carbenicillin-resistant Klebsiella and Pseudomonas aeruginosa.
- Adverse effects were minimal, primarily rash in two patients, with easily maintained therapeutic serum levels.
Conclusions:
- Piperacillin sodium is a safe, well-tolerated, and effective antimicrobial agent.
- It provides a valuable treatment option for infections, particularly those involving resistant Gram-negative bacteria.
- Piperacillin offers a favorable safety profile for clinical use.
