Transcranial magnetic stimulation–associated mania with psychosis: A case report

Transcranial magnetic stimulation (TMS) is a noninvasive procedure used in the treatment of depression. We observed TMS-associated mania with psychotic symptoms in a 55-year-old male diagnosed with MDD and generalized anxiety disorder without history of psychosis or mania. Owing to poor pharmacotherapeutic response and worsening symptomatology, TMS was introduced while continuing phenelzine; this was initially successful in demonstrating positive effects on mood. However, the patient began to develop symptoms consistent with mania with psychosis and was hospitalized. Both TMS and phenelzine were discontinued, leading to significant improvement of the symptoms of mania and psychosis. Phenelzine was later reintroduced for maintenance treatment of depression and anxiety, with no recurrence of mania or psychosis. This case report implicates TMS as a possible cause of mania and psychosis symptoms.

Long-term use of antidepressants, mood stabilizers, and antipsychotics in pediatric patients with a focus on appropriate deprescribing

It is estimated that 8% to 12% of youth are prescribed psychotropic medications. Those in foster care, juvenile justice systems, residential treatment facilities, and with developmental or intellectual disabilities are more likely to be prescribed high-risk regimens. The use of psychotropic medications in this age group is often off-label and can be associated with significant risk, warranting critical evaluation of their role. Landmark trials, pediatric-specific guidelines, and state-driven initiatives play critical roles in supporting evidence-based use of psychotropic medications in children. Overall, there is a lack of literature describing the long-term use of psychotropic medications in youth—particularly with regard to neurobiological, physical, and social changes that occur throughout development. Deprescribing is an important practice in child and adolescent psychiatry, given concerns for over-prescribing, inappropriate polytherapy, and the importance of reevaluating the role of psychotropic medications as children develop.

Managing acute agitation and aggression in the world of drug shortages

Acute agitation and aggression create safety risks for both patients and staff, often leading to psychiatric emergencies. Quick and appropriate treatment is necessary to achieve safe and effective outcomes. Unfortunately, there are several factors that hinder timely interventions, such as medication shortages and delay in staff preparedness. Ultimately, the goal of managing acute agitation and aggression in the clinical setting is to de-escalate the situation and prevent harm to patients and staff. This article will explore useful interventions in realizing treatment goals for the management of agitation and aggression in adults while navigating limitations faced in practice.

Factors influencing performance on the Board Certified Psychiatric Pharmacist Examination: Passing rates and domain-level scores

The Board Certified Psychiatric Pharmacist (BCPP) specialty certification was launched by the Board of Pharmacy Specialties in 1994. Candidates for the BCPP can qualify for the examination through 3 possible pathways: practice experience (4 years) in the specialty, completion of a PGY-1 residency plus an additional 2 years of practice experience, or completion of a PGY-2 specialty residency in psychiatric pharmacy. Recent fluctuations in the passing rate raised questions as to explanatory factors. This article represents the first published comprehensive study of candidate performance on the BCPP Examination. It describes a retrospective, observational study presenting (a) statistical trends of examination passing rates for biannual cohorts over the past 5 years, as well as (b) score distributions on the 3 performance domains of the certification. Pass-rate trend analyses suggest that variation in the proportion of eligibility pathway cohorts in the respective testing samples explains some of the fluctuation in passing rates. An analysis of variance of domain-level scores, using groups defined by eligibility pathway, yielded significant differences for nearly all group comparisons. Evaluation of the effect sizes suggest that the most disparate performance was observed on the core clinical domain, Patient-Centered Care. The results of this study are consistent with previously published research and will inform the upcoming role delineation study for the Psychiatric Pharmacy Certification.

Fluctuation between cigarette smoking and use of electronic nicotine delivery systems: Impact on clozapine concentrations and clinical effect

Unlike with smoking cigarettes, electronic nicotine delivery systems do not cause CYP450 1A2 induction as there is a lack of combustion and polycyclic aromatic hydrocarbon production. Changing to the use of an electronic nicotine delivery system from cigarettes can result in the deinduction of CYP450 1A2 and the increase of certain medication serum concentrations, including clozapine. A case is reported in which the switch from smoking to an electronic nicotine delivery system resulted in increased clozapine serum concentration and constipation, necessitating pharmacologic management. The patient ultimately transitioned back to cigarettes, which resulted in the emergence of psychiatric symptoms. An evaluation of longitudinal serum concentrations and clinical correlation is provided. It is important that patients and health care professionals have knowledge not only about the impact of smoking cigarettes on clozapine metabolism, but also the effects of switching to or from an electronic nicotine delivery system.

Pharmacotherapy treatment of stimulant use disorder

Stimulant use disorder (SUD) is a public health problem in the United States that is associated with increased morbidity and mortality. Psychosocial interventions, such as cognitive behavioral therapy and contingency management, are the main treatment modality for SUDs and no pharmacotherapy is currently FDA approved for this indication. Although some medications show promising data for the treatment of SUD, the evidence remains inconsistent, and the clinical application is limited due to the heterogenicity of the population and the lack of studies in patients with various comorbidities. Selection of pharmacotherapy treatment for methamphetamine intoxication, persistent methamphetamine-associated psychosis with methamphetamine use disorder, and cocaine use disorder in patients with co-occurring OUD are discussed in 3 patient cases.

Microdose induction of buprenorphine-naloxone in a patient using high dose methadone: A case report

Background Buprenorphine is a partial mu-opioid receptor agonist approved for the treatment of opioid dependence. The risk of withdrawal symptoms and wait time required to safely initiate buprenorphine provides challenges to both patients and providers. Microdose induction is proposed as a possible solution to ease the transition to buprenorphine; however, little data has been published to date on patients stabilized on methadone doses greater than 100 mg. Case Report A 29-year-old patient stabilized on methadone 105 mg was successfully transitioned to sublingual buprenorphine-naloxone using a 7-day microdose protocol on an inpatient psychiatric service. During the transition, the patient reported only minimal symptoms. Conclusion This report adds to the growing literature supporting the use of a microdose induction to initiate buprenorphine-naloxone. Additionally, this approach may be significant for patients stabilized on high doses of methadone who may not be able to tolerate a traditional buprenorphine induction.

Clinical pearls for the monitoring and treatment of antipsychotic induced metabolic syndrome

Antipsychotic medications increase the risk of metabolic syndrome, which then increases the risk of atherosclerotic cardiovascular disease and premature death. Routinely monitoring for signs of metabolic syndrome in patients taking antipsychotics allows for early detection and intervention. Psychiatric pharmacists can improve patient care through metabolic syndrome monitoring and recommendation of appropriate interventions. Monitoring for the metabolic adverse effects of antipsychotics, management of weight gain, and management of lipids and blood pressure are explored through 2 patient cases.

COVID-19 reinfection in a patient with a serious mental illness within a long-term inpatient psychiatric care hospital

There is an increasing number of case reports of COVID-19 reinfection. The mechanism of reinfection is poorly understood and evolving. Prevention of the transmission of severe acute respiratory syndrome coronavirus 2 for those with a serious mental illness (SMI) living in a congregate setting presents unique challenges. In this case report, we describe an individual with an SMI in a long-term inpatient psychiatric care hospital who was initially diagnosed in June 2020 with COVID-19 infection via a polymerase chain reaction test. Approximately 6 months later, the patient presented with a COVID-19 reinfection and more severe COVID-like symptoms.

Possible inhibitory effects of terbinafine on aripiprazole metabolism: Two case reports

Aripiprazole, an atypical antipsychotic, is a metabolic substrate for cytochrome P450 (CYP)3A4 and 2D6. Terbinafine, an antifungal agent used for onychomycosis, is a CYP2D6 inhibitor and could theoretically reduce the metabolism of aripiprazole. However, there are no published reports describing this interaction. We present 2 female patients hospitalized in a psychiatric unit who were both taking aripiprazole 15 mg daily and terbinafine 250 mg daily prior to admission. The first patient was a 58-year-old female who was prescribed aripiprazole and terbinafine concomitantly for approximately 5 months prior to admission. A commercial pharmacogenetic testing platform classified this patient as a normal metabolizer for CYP3A4 and 2D6. The first patient's serum trough aripiprazole concentration at steady-state concentration (Css) was 207.5 ng/mL. The second patient was a 43-year-old female who was taking aripiprazole and terbinafine concomitantly for approximately 2 weeks prior to admission who had a Css aripiprazole concentration of 278.9 ng/mL. Aripiprazole has a wide therapeutic range (100 to 350 ng/mL) and a reference dose-related drug concentration of 11.7 (mean) ± 5.6 (SD) ng/mL/mg/d. Our patients had Css aripiprazole concentrations 18% and 59% higher than guideline-supported dose-related drug concentrations. Through the use of therapeutic drug monitoring, pharmacogenetic data, electronic pharmaceutical claims data, and the Drug Interaction Probability Scale, we suggest terbinafine possibly increases aripiprazole concentrations 18% to 59%. Further reports are needed to confirm these findings prior to using this information in clinical practice.
