Objectives

  • In this presentation, we will review the most common rationales for

antipsychotic polypharmacy.

  • We will identify which of these rationales warrant antipsychotic

polypharmacy and which do not.

  • We will review an algorithm for antipsychotic treatment strategies.

Common Rationales for Antipsychotic Polypharmacy

SLIDE 6

Case One

  • An 18-year-old male with no prior psychiatric history and no

significant medical or substance history is diagnosed with first episode psychosis after experiencing symptoms of auditory hallucinations and referential delusions daily for the past month. He is prescribed risperidone but has no insight into his illness and

  • nly takes the medication once or twice a week. After several weeks
  • f this pattern, there is no noted improvement in his symptoms.

What is the most likely reason the antipsychotic is ineffective for treating the psychosis?

A. This particular antipsychotic is not effective for this particular patient. B. This patient is likely a non-responder to all antipsychotic medications. C. This patient was not treated with an adequate dose of antipsychotic medication to accurately judge its effectiveness. D. This patient was not treated for a sufficient length of time to accurately judge the antipsychotic medication’s effectiveness. E. This patient was not taking the antipsychotic consistently enough to accurately judge the medication’s effectiveness.

Poor Treatment Response to Monotherapy Due to Non-Adherence

  • A common cause of poor treatment response is poor medication

adherence.

  • The goal should be at least 80% adherence.
  • Antipsychotic polypharmacy is not a valid treatment strategy in cases of

poor response due to sub-optimal adherence.

  • A long-acting injectable antipsychotic is the preferred

strategy in this case.

SLIDE 9

Non-adherence in the treatment of chronic disorders

  • In developed countries, about 50% of patients with chronic diseases adhere to long-term

therapy1

  • 33–69% of all medication-related hospital admissions in the US are due to poor

medication adherence2

  • One-third of all prescriptions are never filled3
  • >50% of filled prescriptions are associated with incorrect administration (not taken as

prescribed)3

  • 1. WHO Report 2003; Adherence to long-term therapies: evidence for action; 2. Osterberg, L and Blaschke,

Case Two

  • A 20-year-old woman with history of newly diagnosed

schizophrenia is prescribed aripiprazole during her first inpatient admission. The dose is quickly maximized to 30mg

  • ver 1 weeks time and she takes it as prescribed. After 2

weeks of treatment, her positive symptoms of psychosis have improved somewhat, but her treatment team is considering adding another antipsychotic as some symptoms persist.

Poor Treatment Response to Monotherapy Due to Inadequate Trial Length

  • A common cause of poor treatment response is

inadequate trial length.

  • In general, 6 week duration is the standard appropriate

acute trial length.

  • In first episode psychosis, acute trials of up to 16 weeks

are appropriate.

slide-14
SLIDE 14

Case Three

  • A 45-year-old man with history of multiple episode schizophrenia and

good prior treatment response to olanzapine is admitted for decompensation of symptoms after his insurance changed a few months ago and he was not able to continue with his most recent

  • psychiatrist. He is seen in an Emergency Department and started on
  • lanzapine 5mg and referred to an outpatient clinic that takes his
  • insurance. It has taken about 3 months to see the psychiatrist there

due to a long waiting list. Once he meets the psychiatrist there, despite taking the olanzapine 5mg daily (getting refills from Emergency Departments in the interim) he is still significantly symptomatic.

Poor Treatment Response to Monotherapy Due to Inadequate Dose

  • A common cause of poor treatment response is inadequate

dose.

  • Doses should be maximized as trials approach 6 weeks.
  • Doses are generally lower in first episode psychosis, but

should be maximized as trials approach 16 weeks.

slide-17
SLIDE 17

Case Four

  • A 30-year-old woman with a long duration of untreated psychosis is

started on an antipsychotic medication after psychiatry is consulted while she is hospitalized for a minor medical procedure. She is started

  • n risperidone and referred to outpatient treatment. She agrees to a

long-acting injectable antipsychotic of paliperidone and thought started on the recommended maintenance dose, is increased over the next 4 months due to non-response of her symptoms to treatment.

Case Five

  • After the 30-year-old woman from the last vignette was switched

from paliperidone LAI to olanzapine and transitioned to its LAI formulation, her symptoms still do not respond despite another 2 months on the new medication.

…a trial of clozapine is recommended for patients with history of suboptimal response to trials of 2 antipsychotic agents (assuming adequate dose, duration, and adherence)

What is an adequate dose and duration of f a clozapine trial?

  • 30% of patients will respond by 6 weeks
  • 20% of patients will respond by 3 months
  • 10-20% of patients will respond by 6 months
  • Some patients will take more than 6 months to respond
  • A trial of clozapine monotherapy of 6-12 months is reasonable

Consider augmentation with ECT after suboptimal response at adequate plasma level (450ng/mL) for adequate duration.

Cross Tit itration fr from One Antipsychotic to Another

  • Two antipsychotics may be temporarily prescribed at the same time

when changing from one antipsychotic to another due to poor response or inability to tolerate side effect.

Use of f an dif ifferent second antipsychotic for treating delirium or r acute agit itation

  • Not all antipsychotics are available in short acting intramuscular or

intravenous injectable options.

  • Sometimes a second antipsychotic is prescribed in acute settings

such as inpatient medical or psychiatric hospitals in order to acutely treat dangerous behavior for patients who are not able or willing to take the medication by mouth.

Acute symptomatic hyperprolactinemia

Byerly et al 2007

slide-34
SLIDE 34

A study showing that adding a dopamine partial agonist (aripiprazole) can reverse prolactin elevations from other antipsychotics

  • Chen and colleagues (Psychoneuroendocrinology 2015) randomly

assigned patients with schizophrenia and risperidone-induced hyperprolactinemia to…

  • 8 weeks of placebo (n=30) or oral aripiprazole 5mg/day (n=30),

10mg/day (n=29), or 20mg/day (n=30) added on to fixed dose risperidone treatment.

  • Serum prolactin levels were measured at baseline and after 2, 4 and 8

weeks.

slide-35
SLIDE 35

A study showing that adding a dopamine partial agonist (aripiprazole) can reverse prolactin elevations from other antipsychotics

  • 89.9% of patients completed the study.
  • All three aripiprazole doses resulted in…
  • significantly lower prolactin levels (beginning at week 2)
  • higher response rates (≥30% prolactin reduction) and
  • higher prolactin normalization rates than placebo.
  • Effects were significantly greater in the 10 and 20mg/day groups than

the 5mg/day group.

slide-36
SLIDE 36

But….why use 2 antipsychotics when you can use ju just one?

The first line treatment for patients with symptomatic hyperprolactinemia is… …switching to an antipsychotic that does not cause prolactin elevation (aripiprazole)

slide-37
SLIDE 37

Situations when switching isn’t possible

  • The patient has a history of lack of response or intolerance to a

variety of antipsychotics and is doing well with their current antipsychotic except for symptomatic hyperprolactinemia

  • The patient has insurance limitations that would make a switch

difficult

  • For example, a patient who needs/wants LAI treatment but their insurance
  • nly covers a limited range of LAIs (insurance does not cover the LAI

formulations: aripiprazole monohydrate or aripiprazole lauroxil)

Summary Treatment Algorithm

An adequate trial of an antipsychotic in first episode psychosis is 12 – 16 weeks A patient should have 2 subop

  • ptimal antip

tipsychotic tri trials of maxi ximized dose

  • se and 80% adherence for at

t lea least t 6 weeks duration before their illness is considered treatment refractory. One of these trials id idea eally ly shou
