GENETIC VARIATIONS OF CYP2B6 ENZYME AND THE RESPONSE TO MEPERIDINE IN ORAL SEDATION

Purpose: The purpose of this study was to determine the relationship of CYP2B6 genotype to the clinical response to meperidine in pediatric dental patients. Methods: Twenty-five patients, ASA I/ II, 45–92 months old, received an oral sedative regimen containing meperidine for dental treatment. The North Carolina Behavior Rating Scale (NCBRS) and Overall Effectiveness of Sedation Scale (OESS) were used to assess their behavior and sedation outcome. Saliva DNA samples were genotyped by PCR-RFLP. Results: We found the following genotype distributions: homozygous wild-type 1*1 (n = 8, 32%), heterozygous 1*6 (n = 13, 52%), and homozygous variant 6*6 (n = 4, 16%). The genotypes were predictive of a significant decrease in the overall effectiveness of sedation. Conclusion: Variation in CYP2B6 appears to be predictive of less successful sedations; wild-type individuals experienced more successful sedations than the homozygous variant 6*6. Future research regarding the enzyme kinetics of meperidine is needed to determine the exact enzymatic function of CYP2B6 and its variants.
