title: [Design and application of oral sustained-release anticancer drug--a new oral dosage form of cisplatin].
abstract: As compared to the conventional standard chemotherapy of solid cancer such as lung, biochemical modulation (BCM) therapy has been proven to have a good therapeutic efficiency. BCM therapy uses the low dose and low infusion rate of anti-cancer drug. To increase of the QOL of cancer patients, oral BCM therapy is needed. For this purpose, two kinds of new oral sustained-release cisplatin preparations were developed, micro-porous CDDP capsule made of ethylcellulose(EC) and CDDP-EC-stearic acid solid dispersion. After oral administrations of these preparations, serum CDDP levels were maintained over 0.2 microgram/ml for 24h. Experimental therapy using P815 tumor cells transplanted mice suggested the usefulness of CDDP solid dispersion preparation.
