title: [Liver concentration of CPT-11, SN-38 and SN-38 GLU in intraperitoneal and intravenous administration of CPT-11].
abstract: Our previous mouse experiment showed intraperitoneal administration of CPT-11 was more effective not only for peritoneal seeding but for liver metastases than intravenous administration of CPT-11. We studied tissue concentrations of the liver when CPT-11 was administered intraperitoneally or intravenously for ICR mice. Mice liver was resected at 15 min, 1, 2, 4, 8 and 26 hours after intraperitoneal or intravenous administration of 40 mg/kg CPT-11. CPT-11, SN-38 and SN-38 GLU were measured with HPLC. The liver concentration of CPT-11 at 15 min after intravenous administration was higher than after intraperitoneal administration. A higher liver CPT-11 concentration was prolonged in the intraperitoneal administration group. No differences were demonstrated in the concentrations of SN-38 and SN-38 GLU between i.p. and i.v. groups.
