Tardive dyskinesia and dystonia are intractable extrapyramidal symptoms caused by the blockade of dopamine receptors by antipsychotic drugs. In addition to the reduction or discontinuation of the causative drug, valbenazine for tardive dyskinesia and botulinum toxin for tardive dystonia have been reported to be effective. However, their efficacy has not been fully demonstrated. In this study, we report the case of a female patient with bipolar disorder, valbenazine-resistant tardive dystonia, and tardive dyskinesia who achieved improvement in extrapyramidal symptoms with electroconvulsive therapy. Additionally, we conducted a narrative literature review on the safety and efficacy of electroconvulsive therapy for tardive dyskinesia and dystonia.

BACKGROUND: Insomnia is more common as people age. Several common hypnotics used to treat insomnia often do not adequately alleviate sleep issues in older adults and may be associated with negative residual effects such as an increased risk of falls, cognitive impairment, automobile accidents, and lack of response to auditory stimuli. The objective of these analyses of three clinical studies was to investigate the efficacy and safety of the dual orexin-receptor antagonist lemborexant (LEM) in older adults. METHODS: Study E2006-G000-304 (Study 304; NCT02783729) was a randomized, double-blind, placebo (PBO)-controlled, active-comparator trial where subjects with insomnia disorder received LEM 5 mg (LEM5), LEM 10 mg (LEM10), zolpidem tartrate extended-release 6.25 mg (ZOL), or PBO for 30 days. In crossover Study E2006-E044-106 (Study 106; NCT02583451), healthy subjects (good sleepers) received LEM 2.5 mg, LEM5, LEM10, or PBO for eight nights or zopiclone on days 1 and 8 (and PBO on days 2-7). In crossover Study E2006-A001-108 (Study 108; NCT03008447), healthy subjects received a single dose of LEM5, LEM10, PBO, or ZOL. Sleep assessments included polysomnography-based latency to persistent sleep (LPS), wake after sleep onset (WASO), WASO in the second half of the night (WASO2H), sleep efficiency, postural stability, middle-of-the-night and next-day cognitive performance, middle-of-the-night auditory awakening threshold and return-to-sleep latency, and driving performance. RESULTS: Overall, 453 of 1006 (45%; Study 304), 24 of 48 (50%; Study 106), and 28 of 56 (50%; Study 108) subjects were aged ≥ 65 years. In Study 304, LEM decreased (improved) LPS, WASO, and WASO2H from baseline more than ZOL and PBO; subjects treated with LEM had greater increases in sleep efficiency (improved) than with ZOL or PBO. In both Studies 304 and 108, postural stability was not impaired at waketime in subjects who received LEM compared with PBO. At waketime, LEM did not impair memory compared with PBO. In Study 108, following middle-of-the-night awakening, LEM and ZOL did not affect subjects' ability to awaken to auditory stimuli; LEM did not affect tests of memory and attention. In Study 106, LEM did not impair next-day driving performance in healthy elderly compared with PBO. LEM was well tolerated in subjects aged ≥ 65 years. CONCLUSIONS: LEM provided benefits on sleep variables without next-morning residual effects in subjects aged ≥ 65 years, supporting LEM as a treatment option for older adults with insomnia.

Daridorexant is a dual orexin receptor antagonist for the treatment of insomnia. We report results from the first two randomised, double-blind clinical studies of daridorexant in Japanese subjects. In the Phase 1 study, daridorexant (10, 25, 50 mg) or placebo were administered in the morning for 4 days in 24 young (mean age 26.9 years) and 24 older (mean age 69.7 years) healthy Japanese adults. Daridorexant reached a peak plasma concentration within 1.0 h across every dose and age group. For all doses, the mean plasma concentration of daridorexant showed a similar change between the age groups. Exposure parameters increased dose-dependently with minimal/no accumulation upon repeated dosing. The terminal half-life was ~8 h. In the Phase 2, four-period, four-way crossover study, 47 Japanese subjects (mean age 50.4 years) with insomnia disorder were randomised to receive four treatments (daridorexant 10, 25, 50 mg, placebo) during four treatment periods, each consisting of two treatment nights (5-12 day washout between treatment periods). Subjects continued their fourth treatment for 12 further days. A statistically significant dose-response relationship (multiple-comparison procedure-modelling, p < 0.0001) was found in the reduction of polysomnography-measured wake after sleep onset (WASO; primary endpoint) and latency to persistent sleep (secondary endpoint) from baseline to days 1/2. Statistically significant dose-response relationships were also observed for secondary subjective endpoints from baseline to days 1/2 (sWASO, latency to sleep onset). All daridorexant doses were well tolerated, with no treatment discontinuations and no next-morning residual effects. These results supported further investigation of daridorexant in Japanese patients with insomnia disorder.

BACKGROUND: When considering changing hypnotic pharmacotherapy, lemborexant has attracted attention as a candidate due to its effectiveness and safety profile. However, few studies have investigated switching patterns in clinical practice. RESEARCH DESIGN AND METHODS: We conducted a retrospective cohort study using a nationwide claims database. Patients prescribed a single hypnotic who either subsequently switched to (switching cohort) or were additionally prescribed (add-on cohort) lemborexant between July 2020 and December 2021 were identified. Proportion of successful switching was defined as remaining on lemborexant alone or without any hypnotic at six months after lemborexant initiation. RESULTS: Success proportion was 70.1% in the switching cohort (n = 4,861) and 38.6% in the add-on cohort (n = 9,423). In the add-on cohort, success proportion was lower in patients with a hypnotic history of ≥180 days (31.4%) and in patients whose prescribed hypnotic was a benzodiazepine or non-benzodiazepine (31.5% and 37.6%, respectively). CONCLUSION: Proportion of successful switching was higher in patients who switched to lemborexant than in those who added lemborexant as a concomitant treatment. The lower success proportion in the add-on cohort might be related to clinically more severe insomnia, and/or a concomitant prescription of a benzodiazepine or non-benzodiazepine, from which discontinuation may be challenging.

INTRODUCTION: Guidelines for various psychiatric disorders recommend short-term use of benzodiazepine anxiolytic monotherapy in few cases. Contrarily, benzodiazepine anxiolytic polypharmacy (BAP) is not recommended in any case. However, BAP is often used in real world. Therefore, this study aimed to determine the association between BAP and concomitant use of psychotropic medications. METHOD: This retrospective cross-sectional study used claims data from the Japan Medical Data Center. Medical information of health insurance subscribers treated with benzodiazepine anxiolytics in June 2019 was extracted. Prescription of two or more benzodiazepine anxiolytics was defined as BAP. Binary logistic regression analysis was performed to investigate the factors associated with BAP, using age group, sex, type of subscriber, and number of concomitant hypnotics, antidepressants, and antipsychotics (none, one, and two or more) as covariates. RESULT: The eligible participants were 104,796 adults who were prescribed benzodiazepine anxiolytics. Among them, 12.6% were prescribed two or more drugs. Logistic regression analysis revealed that BAP was significantly associated with those who received hypnotic monotherapy (adjusted odds ratio [aOR]: 1.04, 95% confidence interval [CI]: 1.001-1.09, p=0.04), antidepressant monotherapy and polypharmacy (aOR: 1.57, 95% CI: 1.51-1.63, p<0.001 and aOR: 1.98, 95% CI: 1.88-2.09, p<0.001, respectively), and antipsychotic monotherapy and polypharmacy (aOR: 1.12, 95% CI: 1.07-1.19, p<0.001 and aOR: 1.41, 95% CI: 1.30-1.54, p<0.001, respectively). Conversely, lower BAP was associated with those who received hypnotic polypharmacy (aOR: 0.86, 95% CI: 0.81-0.91, p<0.001). DISCUSSION: This study showed that the greater the number of concomitant antidepressants and antipsychotics, the greater the association with BAP. Since combination therapy with antidepressants or antipsychotics is generally not recommended, patients receiving combination therapy with these medications may be resistant to pharmacotherapy. Therefore, implementing the recommended non-pharmacological treatments may reduce BAP.
