Summary

Pivmecillinam, a new penicillin-like antibiotic, is a member of the amidinopenicillanic acid group. Its mode of action differs from that of the classical penicillins and it exhibits no cross-resistance with them. Fifty-two gerontopsychiatric patients, median age 81 years, withE. coli, Klebsiella, andProteus bacteriurias were divided into three comparable groups. In a ten week open clinical trial the patients were treated with pivmecillinam, pivampicillin or the two drugs given alternately in doses reduced in stages. The bacteriuria in all groups cleared almost completely in three days. Pivmecillinam compared favourably with pivampicillin especially at the end of the reduced medication. The alternating treatment seemed to be superior to treatment with either drug administered separately. No development of resistance was observed. No toxic effect on the liver, kidney, or bone marrow was seen in any of the three groups. In the group receiving pivmecillinam alone, no ampicillin-like skin rashes occurred.

Zusammenfassung

Pivmecillinam, ein neues penicillinartiges Antibiotikum, gehört zur Gruppe der Amidinopenicillinsäuren. Seine Wirkungsweise unterscheidet sich von derjenigen der klassischen Penicilline und es entwickelt keine Kreuzresistenz mit ihnen. 52 geriatrischpsychiatrische Patienten im Durchschnittsalter von 81 Jahren, dieE. coli, Klebsiella undProteus im Harn aufwiesen, wurden in drei vergleichbare Gruppen eingeteilt. In einem zehnwöchigen offenen klinischen Versuch wurden die Patienten mit Pivmecillinam, Pivampicillin oder mit beiden Medikamenten abwechselnd in stufenweise reduzierten Dosen behandelt. In allen Gruppen wurde die Bakteriurie in drei Tagen nahezu vollständig beseitigt. Pivmccillinam verglich sich günstig mit Pivampicillin, besonders in der Endstufe der reduzierten Medikation. Die abwechselnde Behandlung schien der getrennten Behandlung mit jeweils einem der beiden Medikamente allein überlegen. Es wurde keine Resistenzentwicklung beobachtet. In keiner der drei Gruppen zeigte sich eine toxische Wirkung auf Leber, Niere oder Knochenmark. In der ausschließlich mit Pivmecillinam behandelten Gruppe traten keine Ampicillin-artigen Hautausschläge auf.
