Ceftriaxone compared with a combination of ampicillin and chloramphenicol in the treatment of bacterial meningitis in adults.
Thirty patients, 25 males and 5 females, aged 16-30 years (mean 21.8 years) with bacterial meningitis were assigned randomly into one of two therapeutic regimens. Patients in Group I received ceftriaxone 100 mg/kg (max 4 g) intravenously (i.v.) once daily. Those in Group II received ampicillin i.v. 160 mg/kg/day plus chloramphenicol i.v. 100 mg/kg/day every 6 h. Of the 15 patients in Group I, N. meningitidis was isolated from 11 patients and S. pneumoniae from 4; and of the 15 patients in Group II, N. meningitidis was isolated from 10 patients and S. pneumoniae from 5. Response to therapy as measured by mortality, time taken for defervescence and for patients to regain full consciousness were comparable in the two groups. One patient in each group died; both died within 24 h of initiation of therapy. The mean no. of days taken to become afebrile were 3.4 and 3.5 and to regain full consciousness were 3.9 and 3.5 for Groups I and II respectively. Ceftriaxone given i.v. appears to be as effective as a combination of ampicillin and chloramphenicol in the treatment of adult patients with meningitis due to N. meningitidis and S. pneumoniae. However, the once-daily schedule of ceftriaxone is more convenient, saving nursing time and expense.
