1200The use of phenytoin metabolism to produce S-HPPH accounts for more than 85% of its metabolism. This metabolic pathway is mediated by the activity of CYP2C9.
The purpose of the present study is:
To confirm the use of phenytoin metabolic ratio as a marker of CYP2C9 activity
To correlate phenytoin metabolic ratio with CYP2C9 genotype
To study the frequency distribution of CYP2C9 activity in-vivo
Inclusion Criteria: Age range of 20-50 years old Absence of significant disease states Exclusion Criteria: The presence of significant disease states The use of drugs (including birth control pills)
