  • Atypical Antipsychotic Drug Use in Children and AdolescentsBy: Alicia ShellSpring 2008Advisor: Dr. Bill Grimes, PA-C

  • Why is this important to us?As primary care providers we are going to have the opportunity to act as a psychiatric first responderReferral to psychologist/psychiatristFollow-up care (esp. in rural areas)

  • BackgroundAtypical Antipsychotic Drugs: A newer class of prescription medications used to treat psychiatric conditionsExact MOA unknown but thought to be due to blockade of both the dopamine-2 receptor as well as the serotonin 5-HT2A receptor

  • Atypical Antipsychotic DrugsClozapine (BN: Clozaril)Risperidone* (Risperdal)Olanzapine (Zyprexa)Quetiapine (Seroquel)Ziprasidone (Geodon)Aripiprazole (Abilify)

  • Atypical Antipsychotic Drugs contd

    Used to treat a wide variety of psychiatric disturbances including: SchizophreniaAcute maniaBipolar maniaPsychotic agitationBipolar maintenance

  • Atypical Antipsychotic Drugs contdTheir use has supplanted the older typical antipsychotic drugs due to the fact that they are thought to cause less extrapyramidal side effects such as tardive dyskinesiaThis has resulted in a substantial increase in the use of antipsychotics for childhood behavioral disorders

  • Atypical Antipsychotic Drugs contdDangerous side effects include: weight gain, diabetes, and hyperlipidemiaFew studies have been done to show how these drugs affect childrenPossibility that children are more likely to develop these side effects than adults (Fritz 2006)

  • Atypical Antipsychotic Drugs contdRecent studies have documented a dramatic increase in prescribing rates for all of these medications to children and adolescents ranging from 200% to over 500%

    (Fritz 2006)

  • They are being prescribed in the pediatric population to treat:Oppositional defiant disorder (ODD)Conduct disorder (CD)Mood disorders (i.e. Bipolar disorder)Attention deficit/hyperactivity disorder (ADHD)Childhood-onset schizophrenia

  • Early-onset Bipolar Disorder or Childhood Bipolar DisorderHistorically under-recognized, now occasionally over-diagnosed, mood disorder affecting approximately 1% of all children and adolescents (Faust 2006)Diagnosing this disorder is particularly difficult because it can present with a broad spectrum of symptoms of varying severity

  • Initial presentation may involve complaints of:MoodinessFrequent or aggressive oppositional behaviorsAnger that does not resolve within 15 minutesSadness and easy cryingInattentionImpulsiveness

  • Why is early diagnosis of this disorder important?Decrease the morbidity and mortality that is associated with itCurrently estimated that 25-50% of all BD patients will make a suicide attempt in their lifetime and approx. 20% will succeed (Faust 2006)Adolescents with BD are at the greatest risk, particularly those who are rapid cyclers

  • How do we treat it?Unfortunately, there are no specific medications that are indicated for treating this condition in childrenInstead, physicians are using antipsychotic medications designed for adults The problem with this is that the usual adult treatment may not address the needs of young people with recent-onset psychosis and the psychological therapies for psychosis need to be age-specific (Haddock 2006)

  • Antipsychotic prescribing practices in children and adolescents:Clinical experience rather than scientific evidence (Pappadopulos 2002)May be the result of social pressure to use these meds when patient behavior is particularly disruptive or dangerous

  • FIND strategy to identify manic symptoms:Frequency: symptoms occur most days in a weekIntensity: symptoms are severe enough to cause extreme disturbance in one domain or moderate disturbance in two or more domainsNumber: symptoms occur three or four times a dayDuration: symptoms occur 4 or more hours a day, total, not necessarily contiguous(Am. Acad. Child & Adolesc. Psychiatry 2005)

  • If a psychiatric diagnosis is confirmedStart with family-focused psychotherapyParent management trainingDyadic (parent-child) psychotherapyIf drugs are deemed necessary, suggest that that they be used in conjunction with psychotherapy

    (Grimes 2007)

  • Before initiating treatment with an atypical antipsychotic:A personal and family history of obesity, diabetes, dyslipidemia, hypertension, or cardiovascular diseaseWeight and height so that BMI can be calculatedMeasurement of waist circumferenceBlood pressureFasting plasma glucoseFasting lipid profile

  • Weight should be reassessed at 4, 8, and 12 weeks after initiating or changing therapy with an atypical antipsychotic and quarterly thereafter at the time of routine visitsIf a patient gains more than 5% of his or her initial weight at any time during therapy, the patient should be switched to an alternative agentNote: These guidelines were not written for a pediatric population and the 5% weight gain threshold may not be sensitive enough for children and adolescents(Kowatch 2005)

  • ConclusionsBe very discriminate in regards to who we give these drugs toProper evaluation of childs conditionMonitor, monitor, monitor!Dont get complacentBe vigilant in regards to lab tests, psychiatric evaluations, weight monitoring, etc.
