Twice daily ceftriaxone therapy for serious bacterial infections in children

The clinical efficacy and safety of ceftriaxone, a long half-life cephalosporin were evaluated in 48 children with a variety of serious bacterial infections. Clinical cure was achieved in 92% (44 of 48) of patients. Peak serum bactericidal titres for Haemophilus influenzae type b, Streptococcus pneumoniae, Str. pyogenes and Escherichia coli were greater than or equal to 1:1024. Mean peak and trough ceftriaxone levels were 173 and 42 mg/l, respectively. Mild and transient diarrhoea was observed in 10% of patients. Laboratory side effects encountered were eosinophilia, thrombocytosis and neutropenia in another 8%. Ceftriaxone is a useful antibiotic for common childhood infections. Its prolonged half-life allows twice daily administration which reduces problems related to intravenous therapy as well as the cost and personnel time.
