연구 인구
Subjects will include up to 41 risperidone-treated children and adolescents with psychiatric or neurodevelopmental (ND) disorders who participated in one of two previous risperidone pharmacokinetics investigations.
To have a larger sample of poor metabolizer subjects, we plan to enroll at least 8 additional subjects who are on stable treatment with risperidone, and perform risperidone pharmacokinetics analyses. Prospectively enrolled subjects (n = 8) will be CYP2D6 poor metabolizers and will include White / Caucasian subjects, of any socioeconomic status, and will be recruited from inpatients or outpatients at Cincinnati Children's Hospital
설명
Inclusion Criteria:

- Signed, dated informed consent forms
Exclusion Criteria:
- Investigators are unable to contact the subject/legal guardian(s)
- Subject is no longer taking risperidone
- CYP2D6 predicted phenotype other than PM
- Subject is non-White, with respect to race, for PK study participation
- Subject is 18 years of age or older
- Subject is less than 5 years of age
- Subject is pregnant at the time of the full PK study
- Subject/legal guardian unwilling or unable to participate in the study
