抄録

Drug metabolism and disposition studies on panipenem/betamipron (PAPM/BP) were performed by using 14C-labeled panipenem ([14C] PAPM) and betamipron ([14C]BP).<BR>Drugs were administered intravenously as [14C] PAPM/BP, PAPM/[14C] BP, [14C] PAPM or [14C] BP in rats and dogs.[14C] PAPM and [14C] BP were mainly excreted to the urine after being distributed to the kidney, liver, lung or blood. Plasma concentration, excretion rate or tissue distribution of radioactivity in rats between [14C] PAPM/BP and [14C] PAPM alone and between PAPM/[14C] BP and [14C] BP alone gave almost no differences except in the kidney distribution.<BR>In the kidney, the maximum distribution time of [14C] PAPM was delayed by combination dose with BP.
