[The hypertensive effect induced with angiotensin II and the physiological and pharmacokinetic aspects of two-route chemotherapy using CDDP and STS].

Two-route chemotherapy of CDDP and STS was performed in 16 postoperative patients with ovarian cancer under the hypertensive condition of 20 minutes induced with angiotensin II (AT-II). Plasma total CDDP and filtrable CDDP levels serially determined at 15 and 30 minutes after intraperitoneal administration of CDDP (150 mg/body) were significantly higher than under the same condition except for using AT-II. The extreme vasoconstriction in the kidney and other organs during AT-II induced hypertension would protect these organs from CDDP induced toxicities. Furthermore, STS infused immediately after the cessation of AT-II could neutralize the CDDP preventing the occurrence of toxicities. The elevating plasma levels of CDDP might be beneficial to enhance the anticancer effects of CDDP, since the blood flow in cancer tissue was increased during AT-II induced hypertension.
