METHOD OF ESTIMATING THE RISK OF EXPRESSION OF ADVERSE DRUG REACTION CAUSED BY THE ADMINISTRATION OF A COMPOUND, WHICH IS EITHER METABLOIZED PER SE BY UGT1A1 OR WHOSE INTERMEDIATE IS METABOLIZED BY THE ENZYME

摘要

A method of estimating a risk of the expression of an adverse drug reaction caused by the administration of irinotecan; and a method of reducing the adverse drug reaction caused by the administration of irinotecan. A polymorphism on the basis of a difference in the repeating numbers of TA repetitive sequences in the promoter region of UGT1 gene and two types of polymorphisms (bases at the 211- and 686-positions) on the basis of single nucleotide polymorphisms in the exon 1 are analyzed. Based on the analytical data, the risk of the expression of an adverse drug reaction caused by the administration of irinotecan is estimated. Further, the administration doses of irinotecan is designed for individual patients depending on the risk of the expression of the adverse drug reaction , thereby reducing the adverse drug reaction cased by the administration of irinotecan.
