Abstract
We evaluated the acute toxicity of a new dosage form (CDDP-ms) comprized cis-platinum loaded lactic acid oligomer micropheres following intraperitoneal administration in mice. The LD50 value of CDDP-ms was 23.8mg/kg, which was 17.6% of the LD50 value(13.5 mg/kg) of cis-platinum aqueous solution. Autopsy findings revealed no additional toxicity due to the change of the dosage form in to the microspheres.
