The biliary elimination of cefotaxime (CTX) and its metabolite desacetylcefotaxime (DSCTX) were measured by HPLC in nine recently cholecystectomised patients following the i. v. injection of 15 mg/kg body weight of CTX. All of the bile was collected by an original procedure: the inflated balloon of a Fogarty catheter was introduced into the distal branch of a Kehr drain T-tube. Biliary clearance of CTX and DSCTX was measured for 8 h.
Cefotaxime
peaked at 90 min after injection at 34.5 +/- 15.3 mg/l; in the 7-8 h sample it was 2.7 +/- 1.7 mg/l. DSCTX peaked at the same time at 49.3 +/- 17.0 mg/l, and was 4.6 +/- 3.2 mg/l at 8 h. The bile/serum ratio of CTX and DSCTX concentrations was above 1 from the first to the eighth hours (range: 1.35 +/- 1.08 to 11.0 +/- 3.1). The biliary clearance of CTX was 0.190 ml/min. The total amounts of CTX and DSCTX eliminated in bile were respectively 1050 +/- 472.8 micrograms and 1902.7 +/- 804.1 micrograms (0.093 +/- 0.041% of the dose and 0.186 +/- 0.077% of the dose). Considering the minimum inhibitory concentration of the pathogens currently encountered in biliary
sepsis
, CTX should be a suitable antimicrobial agent for the treatment of biliary infections.

Seven neonates were treated with cefotaxime during eight episodes of Gram-negative bacillary meningitis and
sepsis
. The causative organisms were Escherichia coli in six cases and Klebsiella pneumoniae and Enterobacter sakazakii in one each. After identification of the pathogen cefotaxime was used alone in six instances. Two patients with brain abscesses received adjunctive therapy with another antibiotic. The sterility of cerebrospinal fluid was documented after a mean of 3.3 days of therapy. Mean cerebrospinal fluid bactericidal titer was 1:64. All patients recovered with good neurologic outcome.
Cefotaxime
in a dosage of 150 mg/kg/day divided every 6 hours intravenously seems safe and effective therapy for neonatal Gram-negative bacillary meningitis.

Cefotaxime sodium was assigned to the open formulary for 12 months and then was placed on formulary restriction to evaluate the restriction's effect on rate of use by services and appropriateness of use. Over 18 months, 187 cases (72 before and 115 after restriction) were reviewed. The majority of use (prerestriction and postrestriction) was in the medicine, pediatrics, and surgery services. The postrestriction usage rate for the three services increased significantly.
Cefotaxime
was used appropriately in 85% of cases during both periods and was not used prophylactically. Appropriateness of use was independent of formulary restriction. During both periods, approximately 76% of patients received cefotaxime for pneumonia,
sepsis
, meningitis, or immunosuppression. Of 205 infections, gram-negative bacilli accounted for over half of the pathogens isolated. Thus, formulary restriction was ineffective in reducing the rate of cefotaxime usage and had no effect on the appropriateness of usage.

We studied the activity of cefotaxime both microbiologically and clinically. 138 blood cultures positive for gram-positive cocci were evaluated (90 strains of Staphylococcus aureus, 25 of Streptococcus faecalis, 13 of Streptococcus alpha and ten of Streptococcus mutans).
Cefotaxime
showed good activity against all strains with the exception of S. mutans, of which only 30% were sensitive. Ten cases of gram-positive infections were studied clinically: six
sepsis
cases and one endocarditis case due to S. aureus, two
sepsis
cases caused by Streptococcus alpha and one Enterococcus endocarditis case. Therapy was successful in nine; the S. aureus endocarditis failed. The local and general tolerance of cefotaxime was good.

In a double-blinded trial, 142 patients were randomized to receive placebo, cefazolin, cefoxitin or cefotaxime during high-risk gastroduodenal, biliary tract or small bowel surgery. Of the 125 evaluable patient trials, postoperative wound infection or intra-abdominal
sepsis
developed in 14/29 (48%) of placebo controls, 8/24 (33%) cefazolin, 7/37 (19%) cefoxitin, and in 2/35 (6%) of cefotaxime recipients. When patients undergoing vagotomy and pyloroplasty with prior cimetidine therapy were excluded, cefotaxime was superior to cefoxitin prophylaxis (2/26 versus 7/28, P = 0.014).
Cefotaxime
may be useful as a prophylactic agent in high-risk upper gastrointestinal surgery.

The safety and efficacy of cefotaxime versus a combination of gentamicin and clindamycin were compared in a prospective, randomized study of 98 surgical patients with polymicrobial soft-tissue infection or septicemia. Forty-nine patients received cefotaxime (20 mg/kg every six hours), and 49 received gentamicin (1 mg/kg every eight hours) plus clindamycin (5 mg/kg every six hours); all drugs were given intravenously. Overall, there was no statistical difference in clinical response to the two regimens, infection being eliminated in 73% of the patients treated with cefotaxime and 71% of those given gentamicin plus clindamycin. Adverse effects were mild and self-limited in both treatment groups, although three patients treated with gentamicin plus clindamycin experienced some loss of renal function. Most aerobic gram-negative rods were sensitive to both cefotaxime and gentamicin, but anaerobes were slightly more sensitive to clindamycin than to cefotaxime.
Cefotaxime
appeared to be at least as effective as gentamicin plus clindamycin in the treatment of polymicrobial soft-tissue infections and septicemia, and, in light of the loss of renal function associated with the gentamicin-clindamycin regimen, somewhat safer. The high failure rate among patients on both regimens with septicemia of unknown origin (five of the nine treated with cefotaxime and two of the four treated with gentamicin and clindamycin), however, indicates the critical role of surgical management in the treatment of polymicrobial soft-tissue
sepsis
.

Fundamental and clinical investigations of cefotaxime were carried out in neonates. The following results were obtained. 1. Seven neonates with serious infections caused by identifiable pathogens, including Group B streptococcal meningitis and Group A streptococcal
sepsis
, were treated by intravenous bolus injection of 20-200 mg/kg of cefotaxime 2 or 3 times daily (60-400 mg/kg/day). The clinical efficacy of cefotaxime was assessed to be good in 6 patients and fair in 1 patient. Bacteriological efficacy was evaluable in 4 patients, all of whom displayed complete eradication of pathogens. 2. Among 22 neonates administered cefotaxime, adverse reactions appeared in 3 patients. Adverse reactions consisted of a transient skin rash in 1 patient and elevation of GOT in 2 patients. 3. Serum concentrations of cefotaxime and desacetyl cefotaxime were investigated in 8 mature infants and 5 immature infants on days 0-7 postpartum. A single intravenous injection of 20 mg/kg produced peak serum concentrations of 31.8-49.7 mcg/ml, associated with a half-life of 1.38-4.47 hours, in mature infants and peak serum concentrations of 35.5-55.0 mcg/ml, associated with a half-life of 3.22-6.43 hours, in immature infants. On days 0-2 postpartum the half-life was longer than on subsequent days. This tendency was particularly remarkable in immature infants. Serum concentrations of desacetyl cefotaxime displayed high individual variations; no consistent trends were noted. 4.
Cefotaxime
and desacetyl cefotaxime serum concentrations were studied in 3 neonates undergoing exchanged transfusion (exchanged volume 177-180 ml/kg) on 1-4 days postpartum. Serum concentrations of cefotaxime after exchanged transfusion were equivalent to 32.6-63.9% of the pretransfusion level, while those of desacetyl cefotaxime were 75.2-106% of the pretransfusion level. 5. Minimal inhibitory concentration (MICs) and minimal bactericidal concentration (MBCs) of cefotaxime were determined against clinical isolates. MICs for inoculum sizes of 10(8)/ml and 10(6)/ml were respectively 3.13-25 mcg/ml and 3.13-25 mcg/ml against S. aureus, 0.024 mcg/ml and 0.012 mcg/ml against Group A Streptococcus, 0.05 mcg/ml and 0.05 mcg/ml against Group B Streptococcus and 0.39 mcg/ml and 0.1 mcg/ml against E. coli. MBCs for an inoculum size of 10(6)/ml were 3.13-100 mcg/ml or over against S. aureus, 0.012 mcg/ml against Group A Streptococcus, 0.39 mcg/ml against Group B Streptococcus and 1.56 mcg/ml against E. coli.

Cefotaxime
(
CTX
) was used in the treatment and prophylaxis of infections in neonates and immature infants. The following results were obtained. 1. Mean serum concentrations (bioassay) 30 minutes after a single intravenous injection of about 20 mg/kg of
CTX
were 44.5 mcg/ml in neonates and 47.2 mcg/ml in immature infants aged 0-3 days, 45.8 mcg/ml in neonates and 56.4 mcg/ml in an immature infant aged 4-7 days and 40.6 mcg/ml in neonates and 38.1 mcg/ml in immature infants aged 8 or more days. Six hour values were respectively 10.9 mcg/ml, 17.0 mcg/ml, 4.6 mcg/ml, 13.4 mcg/ml, 3.8 mcg/ml and 2.7 mcg/ml. 2. Mean serum concentration half-lives were 3.0 hours in neonates and 3.2 hours in immature infants aged 0-3 days, 1.8 hours in neonates and 3.2 hours in an immature infant aged 4-7 days, and 1.5 hours in neonates and 1.6 hours in immature infants aged 8 or more days. 3. Urinary recovery rates were 0.8-78.0% for 0-6 hours after treatment. 4. Adequate clinical efficacy can be expected by the intravenous injection of
CTX
in doses of 20 mg/kg 2 times daily, every 12 hours, in neonates and immature infants aged 0-3 days, 20 mg/kg 3 times daily, every 8 hours, in neonates and immature infants aged 4-7 days, and 20 mg/kg 3 to 4 times daily, every 6-8 hours, in neonates and immature infants aged 8 or more days. 5. The clinical efficacy of
CTX
was good in all 4 cases of
sepsis
(including suspected case), excellent in 1 case of urinary tract infection, and good in all 4 cases of fever of unknown origin for a cure rate of 100%. 6. Adverse reactions were not noted in any cases.

Cefotaxime
has been used extensively in many pediatric centers in the United States for the past 10 or more years. Its main usage has been for the treatment of various serious bacterial infections in pediatric patients, primarily meningitis and
sepsis
. It has also been used to treat intraabdominal, urinary tract, soft tissue, bone, and joint infections. Although there has been a marked reduction in the incidence of invasive Haemophilus influenzae type b infections following the introduction of effective vaccines, cefotaxime remains very useful against the other common pathogens causing serious infections in pediatric patients. The increasing number of pneumococci resistant to penicillin and third-generation cephalosporins has created a new challenge for the management of serious pneumococcal infections. In many institutions, cephalosporins in general have been overused and abused, resulting in the emergence of resistant organisms and an increasing burden on resources. The judicious use of cefotaxime and other cephalosporins should be emphasized.
