Although aripiprazole is one of the most used antipsychotics, knowledge about serum concentrations in children and adolescents is scarce and age-specific therapeutic ranges have not been established yet. Data of a routine therapeutic drug monitoring service were analyzed in order to evaluate the relationship between dose and serum concentration of aripiprazole in children and adolescents. The study also aimed to evaluate whether the therapeutic reference range defined for adults with schizophrenia (100-350 ng/ml) is applicable for minors.

- Therapeutic drug monitoring (TDM) is crucial in child and adolescent psychiatry, but therapeutic ranges for drugs like quetiapine are only established for adults.
- The study involved 180 pediatric patients and found a weak positive correlation between daily quetiapine dose and serum concentration, but no significant relationship with clinical outcomes.
- Most patients had serum concentrations below the adult recommended lower limit, suggesting that pediatric therapeutic ranges may need to be reevaluated for safety and efficacy.
Background: The relationship between daily dose, serum concentrations, and clinical outcomes of olanzapine as well as the influencing factors thereof in children and adolescents treated for different psychiatric disorders were investigated in daily clinical practice. In addition, it was examined whether the current recommended therapeutic range (TR) for adult patients with psychotic disorders is valid for minors.
Methods: The Competence Network for Therapeutic Drug Monitoring (www.
Information on dose- and concentration-related clinical effects of clozapine treatment in children and adolescents is scarce. This study aimed to examine the relationship between dose, serum concentration, and clinical outcome as well as the influencing factors thereof in paediatric patients treated with clozapine. Data from a routine Therapeutic Drug Monitoring (TDM) service between 2004 and 2014 were studied in 68 patients, aged 11-18 years.

On the basis of the case of a 73-year-old man with therapy-resistant major depressive episode who experienced anticholinergic delirium after adding VPA to AMI, we retrospectively analyzed therapeutic drug monitoring data of the years 2008 to 2010. We assessed cases receiving a combination of AMI and VPA, and obtained a control sample of AMI patients without VPA which were matched for sex, age, daily dose, and comedication.

Methods: Steady-state trough serum concentrations were analyzed in 90 subjects, treated with 25-200 mg sertraline per day. Therapeutic efficacy was assessed by the Clinical Global Impression Improvement subscale and side effects by the Udvalg for Kliniske Undersogelser-Side Effect Rating Scale.
