Cephalexin: clinical and laboratory evaluation in infants and children

Area of Science:

• Pharmacology
• Infectious Diseases
• Microbiology

Background:

• Antibiotic resistance is a growing concern, necessitating effective treatment options.
• Gram-positive cocci and common Gram-negative bacteria like E. coli cause numerous infections.

Purpose of the Study:

• To evaluate the efficacy and safety of cephalexin as an oral antibiotic.
• To determine the spectrum of activity for cephalexin against common pathogens.

Main Methods:

• Clinical assessment of cephalexin's oral absorption and pharmacokinetic profile.
• Microbiological testing against gram-positive cocci (excluding Enterococcus) and specific Gram-negative bacteria (E. coli, Klebsiella).

Main Results:

• Cephalexin demonstrated rapid oral absorption and achieved high concentrations in blood and urine.
• The antibiotic was effective against gram-positive cocci infections and most E. coli and Klebsiella infections.
• Minimal side effects were observed during treatment.

Conclusions:

• Cephalexin is a safe and effective oral antibiotic for treating susceptible bacterial infections.
• Its pharmacokinetic properties and spectrum of activity make it valuable for pediatric and adult patients not requiring intravenous therapy.
