Abstract:
The present invention relates to a method for predicting a drug reaction of tramadol using the genotype of CYP2D6 gene and, more specifically, to a method for predicting metabolic activity of the CYP2D6 enzyme by analyzing single nucleotide polymorphism (SNP) of CYP2D6 gene of Korean people using a primer capable of analyzing SNP and using the analyzed results. Further, the present invention relates to a method for predicting a drug reaction of tramadol by effectively measuring the blood drug concentration of tramadol according to the genotype of CYP2D6 gene. The method of the present invention is useful in selecting a safe drug treatment method and developing and evaluating the personalized drug therapy by predicting a drug reaction for a patient when tramadol is alone administered or co-administered with another drug, through determination of the type of CYP2D6 of the patient.

CONSTITUTION: A method for analyzing the genotype of CYP2C19 gene for predicting drug response to omeprazole comprises the steps of: acquiring exon 4 and exon 5 of a gene encoding CYP2C19 from genomic DNA and determining each base sequence; detecting single nucleotide polymorphisms (SNPs) of each base sequence, wherein 39th base (G) of sequence number 1 (exon 5) is substituted with A (CYP2C19*2) and 155th base (G) of sequence number 2 (exon 4) is substituted with A (CYP2C19*3); and determining if the genotype of CYP2C19 belongs to extensive metabolizer (EM) group, intermediate metabolizer (IM) group, or poor metabolizer (PM) group using the detected SNP. A method for predicting drug response to omeprazole by each CYP2C19 genotype comprises the steps of: orally administering 20-80 mg of omeprazole to each of the EM, IM, and PM groups; and comparing the area under the concentration-time curve (AUC) by each genotype and computing a dosage of omeprazole by each genotype.

Abstract:
PURPOSE: A method of analyzing a CYP2C19 genotype for predicting the effect of lansoprazole is provided to supply a haplotype as a drug-metabolizing enzyme activity index of CYP2C19 engaging in a lansoprazole metabolism and be used as an index about the evaluation of medical supplies metabolized by the CYP2C19 and a cross linkage test by grasping the pharmacokinetics characteristic of equivalent drugs. CONSTITUTION: A method of predicting the lansoprazole metabolic activation of a CYP2C19 protein comprises: a step of determining the each base sequence of the promoter of a gene ciphering cytochrome P450 2C19 (CYP2C19) from genomic DNA, exon 4, exon 5, intron 5 and intron 7; a step of detecting the presence of single nucleotide polymorphism (SNP) in the determined each base sequence; a step of identifying the CYP2C19 gene of experimentee with one among haplotype H1-H3 by using the detected SNP; a step of determining whether the identified haplotype belongs to a haplotype combination group consisting of extensive metabolizer (EM), hetero extensive metabolizer (hetero EM) and poor metabolizer (PM) by assembling the identified haplotype with base pairs; and a step of predicting the lansoprazole metabolic activation of the CYP2C19 protein by using the confirmed haplotype combination group. The lansoprazole metabolic activity is the highest when the haplotype combination group belongs to the EM and is lowest when the haplotype combination group belongs to the PM.
