泌尿器科領域におけるCefmenoxime(CMX)の臨床的検討 ; Clinical study on cefmenoxime (CMX) in urology

Cefmenoxime (CMX)について, 基礎的ならびに臨床的検討を行った.1.健康成人4名に対しCMX250 mgをcross over法を用いて, 筋注, 静注および1時間の点滴静注の3方法で投与した.各投与法における最高血中濃度(時間), 血中半減期はそれぞれ, 筋注5.9±0.1 μg/ml(30分), 1.41時間, 静注11.1±1.2 μg/ml(15分), 1.26時間, 1時間の点滴静注12.4±1.4(点滴静注終了時)0.94時間であった(いずれもMean±S.E.).またCMXの投与後6時間までの尿中排泄率は, いずれも60～70%であった.2.急性単純性膀胱炎4例に対するCMXの有効率は100%であった.3.複雑性尿路感染症10例に対する有効率は70%であった.無効例はいずれもカテーテル留置例でPseudomonasが存続もしくは菌交代として出現したものであった.なお従来のcephalosporin系抗生剤に耐性のSerratiaが陰性化した.4. CMX投与による自覚的副作用は認められなかった.しかし一過性に軽度のtransaminaseの上昇が1例にみられた ; Basic and clinical studies were made on Cefmenoxime (CMX), a new cephalosporin antibiotic, and the following results were obtained. The serum concentration of CMX was examined in four healthy adults after administration of 250 mg of CMX by intramuscular injection, intravenous injection and one-hour intravenous drip infusion (cross over). In the case of intramuscular injection, the peak value of 5.9 micrograms/ml was obtained 30 minutes after administration, and the half-life in serum was 1.41 hours. In the case of intravenous drip infusion, injection, a concentration value of 11.1 micrograms/ml on the average was obtained after 15 minutes of administration, and the half-life in serum was 1.26 hours. In the case of intravenous drip infusion, the concentration was 12.4 micrograms/ml upon completion of drip infusion, and CMX disappeared from serum at a half-life of 0.94 hour. The urinary recovery up to 6 hours was from 60 to 70% in each The efficacy rate of this preparation was 100% for 4 cases of acute simple cystitis. The efficacy rate of CMX was 70% for 10 cases of complicated urinary tract infection; the 3 cases in which CMX was not effective were patients with a residual catheter and Pseudomonas persisting or appearing as superinfection. It was noted that Serratia, which was resistant to the conventional cephalosporin antibiotics, became negative. No subjective side effects due to the administration of this preparation were observed. As for abnormal laboratory findings, a slight and transient rise in transaminases ...
