Ceftriaxone: therapeutic results in various infections and kinetic studies.
Ceftriaxone (Ro 13-9904, Rocephin) was given to 67 patients suffering from 74 various infections. Patients had infections of the urinary tract (36), soft tissue phlegmon (12), infections of the respiratory tract (13), osteomyelitis (7), abscesses (5) and meningitis (1). Infecting organisms were E. coli (26), Proteus spp. (20), P. aeruginosa (7), H. influenzae (6), Enterobacter spp. (6), K. pneumoniae (3), C. freundii (2), S. marcescens (1), S. aureus (4), S. pneumoniae (2), Peptostreptococcus spp. (4) and Clostridium spp. (1). The organisms were often multiresistant. Dosage ranged from 1-2 g once or twice daily i.m. or i.v. The clinical response was excellent in 56 infections (75.6%) while 13 (17.6%) infections were improved and in 5 (6.8%) treatment failed. The pathogen was eradicated in 63 (85.1%), and relapsed in 3 (4.0%) while bacteria persisted in 11 (14.9%). No appreciable side effects or toxicity were observed. Sputum, bile, cerebrospinal fluid and prostatic fluid kinetics revealed ceftriaxone concentrations several times above the minimal bactericidal concentrations required to kill the enterobacteriaceae, but mostly inadequate to inhibit P. aeruginosa strains. Ceftriaxone was a safe and effective drug for the treatment of various infections. However, with the exception of urinary tract infections it should be given with caution in P. aeruginosa infections.
