CLINICAL EXPERIENCE OF NORFLOXACIN(AM-715) IN SUPERFICIAL PYOGENIC INFECTIONS KEIICHI FUJITA The Department of Dermatology, Defence Medical College HISASHI TAKAHASHI, OSAMU KANEKO, TOMOKO SHIMIZU, KENICHIRO CHIKAKANE and TOSHIHIKO ABE The Department of Dermatology, School of Medicine, Teikyo University EIICHIRO NONAMI, NAOSHIGE HORSE, KEIKO SHISHIBA and MICHIRO SHIMOTSUMA The Department of Dermatology, Kanto Teishin Hospital ATSUSHI KUKITA, SHINICHI WATANABE, KIYOSHI YAMADA The Department of Dermatology, YASUO KUBOTA and TOORU SOMEYA Faculty of Medicine, University of Tokyo YASUSHI WATANABE, KOUJI YAMADA, TAKASHI NAGASHIMA MIHOKO YOKOYAMA and EIKO MANO The Department of Dermatology, Central Hospital of Japan National Railway TAKASHI ANZAI, KUMIKO JITSUKAWA, TETSUZAN KANEMARU and YOUKO NIIMURA The Department of Dermatology, Japanese Red Cross Medical Center SUSUMU ONODA The Department of Dermatology, School of Medicine, Toho University MUNEKAZU NISHIWAKI, TAKUYA KITAJIMA and HARUKO HINO The Department of Dermatology, Kanto Chuo Hospital MITSUYOSHI HONDA and SATOMI HATTORI The Department of Dermatology, The 2nd Hospital, Nippon Medical University TAKANORI TOMIZAWA, JUNK() YAMAGUCHI and YOSHIO TAKEUCHI The Department of Dermatology, Kanto Rosai Hospital A new synthetic antibacterial agent, norfloxacin (AM-715) was studied clinically on patients with superficial pyogenic infections at daily dose of 600 mg orally in the field of dermatology, and the following results were obtained. 1. Out of 141 cases, clinical efficacy was evaluated in 124 cases. The overall clinical efficacy was excellent (cured or remarkably improved) in 66.9%, excellent or moderately improved in 86.3%. Within evaluation for each group classified by the type of diseases, clinical efficacies on patient with furuncle, furunculosis and carbuncle (group 2), on patients with impetigo contagiosa, eczema impetiginosum (group 3) on patients with phlegmon, erysipelas, superficial lymphangitis (group 4) and on patients with abscess, suppurative hidradenitis (group 5) were 91.4%, 90%, 100%, and 90%, respectively. Higher clinical responses were obtained in these four groups than the responses in the other patients with folliculitis (group 1) and ulcer (group 6). 2. Overall clinical efficacies classified by species of causative organisms were 95% in patients with S. aureus 84.2% in patients with S. e pidermidis, 87.5% in patients with GNR except for P. aerugtnosa and 75% in patients with P. aeruginosa. 3. MICs distribution of norfloxacin against all strains of clinical isolates S. aureus and S.epidermi-
dis were superior to those of CEX at one or more tubes. 4. Side effect was observed in one case who complained of skin eruption. In the clinical laboratory findings, elevations of GOT, GPT and Al-P were observed in a few cases, but those were normalized after termination of administration. It is considered from above results that norfloxacin (AM-715) is an useful antibacterial agent for the treatment of superficial pyogenic infections in the field of dermatology.
