In an open, controlled, randomized study the safety and efficacy of imipenem/cilastatin was compared with that of the combination cefotaxime/gentamicin (plus metronidazole in patients with suspected anaerobe infection) in the treatment of 337 patients from 12 German and 5 Austrian centers who had non-life-threatening infections. The evaluation was done on an intention-to-treat basis (i.e. all patients including protocol violators) and according to the protocol (144 patients in the imipenem/cilastatin group and 124 in the cefotaxime/gentamicin group). No significant differences were seen between the two treatment groups in terms of the clinical and bacteriological outcome. The frequency of infusion intolerance and thrombophlebitis was low in both groups (< 2%). The overall rate of adverse events was comparable in the two groups, nausea, vomiting and diarrhea being the most frequent events. Nephrotoxicity, indicated by an increase in serum creatinine, was significantly higher in the cefotaxime/gentamicin group. Imipenem/cilastatin was shown to be as effective as cefotaxime/gentamicin (metronidazole) and appears to be well tolerated.

We conducted a randomized trial to compare the efficacy of imipenem/cilastatine (IPM/CS) monotherapy with that of a combination of latamoxef (LMOX) and tobramycin (TOB) in the initial management of fever and neutropenia in patients with lung cancer. Leukocytopenic febrile patients (less than 3,000 leukocytes per microliters; temperature greater than 38 degrees C) with lung cancer given induction therapy were randomly assigned to receive intravenous treatment with either 1 g IPM/CS twice daily or 2 g LMOX plus 90 mg TOB twice daily. A total 101 febrile episodes were studied. Fifty-one episodes were treated with IPM/CS and 50 with LMOX+TOB. Fifty-nine of the febrile episodes were bacteriologically confirmed, while an organism could not be isolated despite the presence of obvious clinical infection in the remaining 42. The response rate was 82% with IPM/CS and 80% with combination therapy. This difference was not statistically significant. The response rate regarding gram-negative infections was 10 out of 14 (71%) in the IPM/CS group and seven out of 12 (58%) in the LMOX+TOB group. This difference was also not significant (P = 0.484). The response rate in severely neutropenic patients (neutrophils less than 100/microliters) was low (P = 0.078). Three patients in the IPM/CS group were withdrawn from the study due to skin rash and vomiting. Therapy with IPM/CS monotherapy was as effective as a combination regimen.

Imipenem/cilastatin sodium (IPM/CS) was administered to 55 patients with respiratory tract infections (RTI). A clinical evaluation of IPM/CS was carried out in 51 patients, 28 with pneumonia, 4 with pulmonary abscess, 1 with pyothorax, 6 with bronchitis, 9 with bronchiectasis, 1 with diffuse panbronchiolitis and 2 with RTI with chronic obstructive pulmonary disease, and the clinical efficacy rate was 78.4%. Causative organisms were isolated in 23 strains out of 20 patients, such as Staphylococcus aureus 4 strains, Staphylococcus epidermidis 1 strain, Streptococcus pneumoniae 1 strain, Branhamella catarrhalis 1 strain, Haemophilus influenzae 2 strains, Klebsiella pneumoniae 4 strains, Pseudomonas aeruginosa 6 strains, Pseudomonas sp. 1 strain, Acinetobacter calcoaceticus 1 strain, Acinetobacter sp. 1 strain and glucose non-fermentative Gram-negative rod 1 strain. An eradication rate of 70.6% was obtained. An overall eradication rate of main causative organisms in RTI including S. aureus, S. pneumoniae, H. influenzae and K. pneumoniae was 75.0%. Clinical adverse effects were observed in 5 patients, and these were eruption in 2, itching in 1, vomiting in 1 and drug fever in 1. Abnormalities in laboratory test results were observed in 8 patients. These disappeared or returned to normal values after completion or discontinuation of IPM/CS administration. IPM/CS appears to be a useful antibiotic for the treatment of RTI, especially severe infections.

Imipenem-cilastatin was evaluated for tolerability and efficacy in a multicenter open, noncomparative trial involving 178 infants and children with bacterial infections. Imipenemcilastatin was administered in total daily dosages of 100 mg/kg for patients up to 3 years of age and 60 mg/kg for those more than 3 years of age. Favorable clinical response was achieved in 98 of 100 patients judged evaluable for efficacy. Adverse effects were generally mild and reversible and included diarrhea alone or with vomiting (5.1%), irritation of intravenous infusion site (3.3%) and rash (2.2%). Changes in laboratory test values reported most frequently were thrombocytosis (8.9%), elevations in aspartate aminotransferase (7.9%) and alanine aminotransferase (5.6%) and eosinophilia (8.4%). This safety profile appears to be comparable to that of other beta-lactam antibiotics. Moreover imipenem-cilastatin was effective in infections caused by a broad spectrum of pathogens that include Haemophilus influenzae, Staphylococcus aureus, P. aeruginosa and anaerobes. These attributes suggest that imipenem-cilastatin should be safe and effective in selected pediatric patients.

Pharmacokinetic and clinical studies on imipenem/cilastatin sodium (IPM/CS) in the perinatal period were carried out, and the results obtained are summarized below. 1. IPM/CS transfers to umbilical cord plasma and amniotic fluid were effective. Passage of IPM/CS into mother's milk was as little as with other beta-lactam antibiotics. 2. Among 81 patients with perinatal infections, clinical efficacies were excellent in 16 patients, good in 62, poor in 3, with an efficacy rate of 96.3%. In addition, IPM/CS was effective in 6 patients for prophylaxis. 3. Out of 82 isolates examined for bacterial responses, 69 isolates were eradicated and 8 isolates were decreased. Especially, of 13 isolates of Enterococcus faecalis, 12 were eradicated. 4. In 109 patients administered with IPM/CS, vomiting was observed in 1 patient. No abnormal laboratory test values were observed. 5. IPM/CS was an effective and safe new antibiotic in perinatal infections. We recommend a normal dose of IPM/CS of 0.5 g/0.5 g twice a day and a dose for severe infections of 1 g/1 g twice a day in the perinatal period.

MK-0787 (Imipenem)/MK-0791 (Cilastatin sodium), a new compound of Thienamycin, was administered in treatment of 35 patients (36 cases) with chronic complicated UTI or for prevention of serious infections with much complicated factors. The patients were principally treated at a daily dose of 1 g for over 10 days. The efficacy rate of 26 patients who were evaluable in the early phase (4-7 days) was 88.5%, while it became up to 92.3% in the final phase judgment. As for clinical usefulness, the result was obtained to be as high as that of the clinical efficacy. In bacteriological study, 35 strains were clinically isolated including 7 strains of P. aeruginosa from UTI. All the strains disappeared with an eradication rate of 100% after treatment. Strains appearing after Imipenem/Cilastatin sodium treatment mainly consisted of fungi. Usefulness judgements tended to be greater in the final phase than in the early phase. As for side effects, vomiting was recorded in one case, in which the administration was discontinued. In laboratory findings there were 3 cases with elevated GPT, 2 cases with elevated GOT, one case with elevated gamma-GTP, one with thrombocytopenia, and one with eosinophilia each, but these abnormal values were slight and transient. In summary our clinical study showed that Imipenem/Cilastatin sodium was a very effective antibiotic in treatment on moderate or serious UTI or preventive use for infections in compromised hosts. Considering the features of this agent, it might be more effective and useful for clinical use in treatment on polymicrobial infections including stubborn organisms than any other antimicrobial compounds. Furthermore, it was safe and well tolerable in a long term treatment.

The placental passage and therapeutic efficacy of imipenem/cilastatin sodium (IPM/CS) were studied in the perinatal period. The results obtained are summarized as follows: 1. The mean biological half-life of IPM in maternal serum was 30 minutes. 2. The umbilical cord serum concentration of IPM was about 70% of that in maternal serum after 30 minutes. 3. A significant level of IPM was found in the amniotic fluid. The amniotic fluid concentration of IPM was over 1 micrograms/ml at 45 minutes after administration and equal to that in maternal serum at about 90 minutes. 4. In 4 patients, the time course of placental transfer of IPM was investigated. The level of IPM in amniotic fluid was higher than that in maternal serum at 90 minutes after administration and gradually increased afterward. 5. The level of IPM was 3.96 micrograms/g in the fetal membranes at 17 minutes after administration. 6. In the treatment of 12 patients with perinatal infections, the preparation showed excellent efficacies in 3 patients and good efficacies in 7 patients. 7. An adverse effect (vomiting) was observed in only one patient. In conclusion, this drug showed satisfactory placental transfer as well as sufficient safety and excellent efficacy in the treatment of perinatal infections.

Imipenem/cilastatin, which combines a broad-spectrum antibiotic derived from thienamycin with a specific enzyme inhibitor, was administered in dosages of 1 to 4 gm/day to 717 patients in a multicenter noncomparative trial. Ninety-nine percent of the bacterial pathogens tested were susceptible to imipenem, and 86% were eradicated. Clinical outcome was favorable in 85% or more of the cases when assessed according to the site of infection, and 92% of the cases responded to treatment overall. Development of resistance was rare except for Pseudomonas aeruginosa, which became resistant in 19% of the patients infected with that organism. More than half the patients with resistant P aeruginosa had a favorable clinical outcome, however. Superinfection occurred in approximately 4% of all patients. The adverse clinical experiences occurring most frequently were related to gastrointestinal function (nausea, vomiting, and diarrhea). In general, the safety profile of imipenem/cilastatin was similar to that of other beta-lactam antibiotics.

Imipenem/cilastatin was compared with the combination of gentamicin plus clindamycin in terms of efficacy and safety for the treatment of moderate to severe infections in an open, randomized study. The rates of cure achieved with the two regimens were similar. Gentamicin/clindamycin treatment failed only in two of four instances of severe infection. Patients given imipenem/cilastatin seemed to respond more rapidly to treatment; this observation applied both to the entire group treated and to the subgroup with moderate intraabdominal infections. Susceptible etiologic agents were more frequently eradicated by imipenem/cilastatin (95%) than by gentamicin/clindamycin (79%). The most common adverse reactions were nausea or vomiting in patients given imipenem/cilastatin and urinary abnormalities in those given gentamicin/clindamycin. Self-limited diarrhea was observed with equal frequency in the two groups. No adverse reactions required the discontinuation of treatment. Colonization or superinfection with resistant organisms and Pseudomonas aeruginosa occurred significantly more often among patients given gentamicin/clindamycin. These results suggest that imipenem/cilastatin is a promising alternative to the combination of gentamicin and clindamycin for the treatment of moderate to severe infections in hospitalized patients.

Imipenem (N-formimidoyl thienamycin) is a new carbapenem beta-lactam antibiotic with a broad antibacterial spectrum. Forty-five patients were treated with either 500 or 1,000 mg of imipenem/cilastatin four times daily, the duration varying according to clinical response. The diagnoses were urinary tract infection, 10 patients; septicemia, six; intraabdominal sepsis, six; pneumonia, six (two cases of Legionnaires' disease); skin and soft tissue infection, four; and other diagnoses, 13. Of the 32 clinically assessable patients, 17 were cured, nine improved, three died, and three were withdrawn from the trial. Of 21 patients who were microbiologically assessable, 13 were cured. In six cases of complicated urinary tract infection, the organism--which had been eradicated from the urine during treatment--reappeared after completion of antibiotic therapy. Two patients developed adverse clinical reactions that were thought to be drug-related (drug-induced fever and nausea plus vomiting, respectively). Both patients had mildly abnormal results in liver function tests, and one developed a positive direct Coombs' test. Fifty-seven percent of the patients developed some degree of phlebitis, which was moderate to severe in 19%. In this study imipenem/cilastatin proved to be a highly effective agent for the treatment of a variety of serious bacterial infections.
