Case Report: Long-Acting Oral Cariprazine

A Versatile Prison Psychiatric Pharmacy Program

BACKGROUND

Before the coronavirus disease 2019 (COVID-19) pandemic, 20% of the adult population in the United States experienced mental illness annually. Since the COVID-19 pandemic, 93% of countries have reported disruptions to mental health services. The demand for services is high whereas infrastructure and qualified professionals are appallingly low. Health care in the correctional setting is unique, where mental illness prevalence is double than that in the community. The intersection of policies and procedures and the beneficence plus nonmaleficence responsibility of health care professionals is exceptionally complex. Studies have shown the potential benefits of pharmacists following patients in chronic care psychiatry visits.

OBJECTIVES

An inpatient psychiatric pharmacy clinic was launched to fill gaps to provide safe and up-to-date patient-centric services for more than 240 extremely psychiatrically ill inmate patients at the Federal Correctional Center Butner (FCC Butner), a Federal Bureau of Prisons medical center.

METHODS

The inpatient psychiatric pharmacist practiced independently under a collaborative practice agreement and completed mental health clinical visits for a revolving portion of 240 inpatient mental health inmate patients at FCC Butner. The pharmacist provided ancillary services including completing movement disorder testing, monitoring narrow therapeutic index medication laboratory test results, and executing an antipsychotic psychoeducation meeting with other health care departments and inmate patients.

RESULTS

Notably, 74% of patients monitored in the specialty program experienced stable or improved symptoms of depression, schizophrenia, and bipolar disorder. Adverse effects, particularly psychiatric-related movement disorders, were also more closely managed. Finally, 43% of the total inmate patient population who previously declined psychiatric medication treatment consented to begin treatment after participation in a pilot antipsychotic psychoeducation meeting.

CONCLUSION

The inpatient psychiatric pharmacy program at FCC Butner is a dynamic program that has bolstered the facility's health care mission. The services detailed in this article can be applied to other correctional environments that have a medical outpatient or inpatient presence.

Successful switching from risperidone to cariprazine in a schizophrenic patient with pronounced functional deficit. Case report

A 22-year-old male was admitted to an in-patient psychiatric unit for treatment, after a period of 2 years of increasing psychotic symptoms corresponding to a very severe case of schizophrenia across the entire scale of symptom disorder domains along with some drug abuse comorbidity. Previous treatments with olanzapine (OLA) and risperidone (RIS) had been at best partly successful toward his positive symptoms with no, or even worsening effects on the negative symptomatology. Given the gravity of the latter symptoms and functional impairment of our patient, he might thus have been a candidate for clozapine (CLZ) treatment. It was however decided to switch his antipsychotic treatment to cariprazine (CAR), an agent with a novel pharmacological and clinical profile, because of its favorable pharmacodynamic, pharmacokinetic, and tolerability/safety properties. In a follow-up on the patient 6 months after discharge he is not fully recovered, but the recovery attained reflects a marked functional improvement compared to before the RIS-to-CAR switch. The remarkable response to CAR observed may, speculatively, be in line with the suggestion that CAR could offer an alternative, safer, and more tolerable monotherapy approach (vs. CLZ) for patients with severe negative symptoms and functional deficiency resistant to standard antipsychotic treatment. He appears to occasionally still be taking drugs, but no worsening of positive symptoms has been noted. Whether or not he could reach full recovery if he would abstain entirely from drugs of abuse remains an open question.

Third-generation antipsychotics in patients with schizophrenia and non-responsivity or intolerance to clozapine regimen: What is the evidence?

Clozapine is considered « the golden standard » for the management of treatment-resistant schizophrenia, but many patients do not present adequate responsivity even to this antipsychotic. If we add the need to strictly monitor the hematologic and cardiometabolic adverse events during each clozapine trial and the difficulty of preserving therapeutic adherence in patients with low insight, residual negative/positive symptoms, or economic challenges, then the necessity of exploring alternative interventions for these patients becomes obvious. Also, in case of intolerance to clozapine or where clozapine did not induce remission, clinicians have to find new ways to help their patients. Switching to other antipsychotics or using these agents as add-ons to clozapine are the main interventions explored in this review, for patients with schizophrenia resistant to clozapine (ultra-resistant schizophrenia, URS). When clozapine intolerance is detected, conversion to another antipsychotic with distinct pharmacologic properties or formulation (e.g., long-acting intramuscular injectable agents, LAI) may be a useful option. Third-generation antipsychotics (TGA) have been selected for their distinct pharmacodynamically profile, which allows, at a theoretical level, their use in combination with clozapine. This narrative review is based on searching four electronic databases, that retrieved 19 primary and secondary reports on aripiprazole (seven case reports or case series presenting 24 patients; nine clinical trials, and three systematic reviews/meta-analyses), two primary reports on brexpiprazole (case report and case series, N = 3 patients), and six primary reports on cariprazine (case reports and case series, N = 14 patients). Based on the information collected from these reports, which included oral and LAI formulations, the TGA most supported by evidence for the augmentation of clozapine is aripiprazole (high-and medium-quality data), followed by cariprazine (low-quality data). Brexpiprazole has not yet been systematically explored for this indication, and in the case of lumateperone, no report could be found. The efficacy of aripiprazole and cariprazine was supported in the domains of positive, negative, and general symptoms, and aripiprazole may positively impact the metabolic profile in patients with URS. Also, adding TGA may lead to a decrease in the dose of clozapine concomitantly administered. More data derived from good quality research are needed in order to confirm the circumstances of TGAs recommendation in patients with URS, either as monotherapy, or added to clozapine.
