[Clinical studies on cefuzonam in obstetrics and gynecological infections]

To evaluate the usefulness and the safety of cefuzonam (CZON, L-105) against obstetric and gynecological infections, we conducted clinical trials and obtained the results summarized as follows. 1. Thirteen patients with obstetric and gynecological infections (intrauterine infection 2 cases, adnexitis 7, 1 case each of abscess of adnexa uteri, abscess of the vaginal wall, pyelonephritis, and mammitis) were treated with CZON. The CZON was administered by intravenous injection or intravenous drip infusion, 1 g twice daily for 4 to 7 days (8 g to 14 g in total). The clinical effect was good in 12 and poor in 1. 2. Four cases, on which other antimicrobial agents were ineffective, responded well to CZON. 3. The CZON displayed excellent effects on anaerobic bacteria (Peptostreptococcus anaerobius, Bacteroides fragilis) and Gram negative rods (Escherichia coli, Klebsiella pneumoniae). 4. No side effects or laboratory abnormalities were observed. 5. From the above results, CZON appeared to be an effective and useful drug for obstetric and gynecological infections.
