Meta-Analysis
INTRODUCTION
This systematic review provides supporting evidence for the accompanying clinical practice guideline on the treatment of central disorders of hypersomnolence in adults and children. The review focuses on prescription medications with U.S. Food & Drug Administration approval and nonpharmacologic interventions studied for the treatment of symptoms caused by central disorders of hypersomnolence.
METHODS
The American Academy of Sleep Medicine commissioned a task force of experts in sleep medicine to perform a systematic review. Randomized controlled trials and observational studies addressing pharmacological and nonpharmacological interventions for central disorders of hypersomnolence were identified. Statistical analyses were performed to determine the clinical significance of all outcomes. Finally, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) process was used to assess the evidence for the purpose of making specific treatment recommendations.
RESULTS
The literature search identified 678 studies; 144 met the inclusion criteria and 108 provided data suitable for statistical analyses. Evidence for the following interventions is presented: armodafinil, clarithromycin, clomipramine, dextroamphetamine, flumazenil, intravenous immune globulin (IVIG), light therapy, lithium, l-carnitine, liraglutide, methylphenidate, methylprednisolone, modafinil, naps, pitolisant, selegiline, sodium oxybate, solriamfetol, and triazolam. The task force provided a detailed summary of the evidence along with the quality of evidence, the balance of benefits and harms, patient values and preferences, and resource use considerations.

OBJECTIVE
Two primary compounds of the cannabis plant (), delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), differentially and dose-dependently affect mood and anxiety. In this systematic review, the authors summarize the design and results of controlled trials assessing the effects of THC and CBD on affective disorders, anxiety disorders, and posttraumatic stress disorder (PTSD).
METHODS
A keyword search of eight online literature databases identified eight randomized controlled trials of defined CBD or THC doses for the target populations.
RESULTS
A 1-month trial of daily THC (up to 3 mg per day) for anxiety disorder reduced anxiety symptoms, but symptoms were very low throughout the study. Another trial of sequential, single-day, low-dose THC in social anxiety disorder found no symptom changes. Two studies reported that single-dose CBD pretreatment reduced anxiety in laboratory paradigms among individuals with social anxiety disorder. A study of daily CBD for 4 weeks among adolescents with social anxiety disorder indicated modest symptom improvements. One crossover trial involving 10 patients with PTSD showed that THC added to standard pharmacotherapy reduced self-reported nightmares. Two small studies of THC for hospitalized patients with unipolar or bipolar depression found no improvement of depression; instead, anxiety and psychotic symptoms emerged in >50% of patients.
CONCLUSIONS
With only eight very small studies, insufficient evidence was found for efficacy of CBD and THC to manage affective disorders, anxiety disorders, or PTSD. Therefore, medical cannabis should not be recommended for treating patients with these disorders. Further research should investigate the safety and efficacy of managing psychiatric disorders with cannabinoids.

Meta-Analysis
IMPORTANCE
Antipsychotic-induced akathisia (AIA) occurs in 14% to 35% of patients treated with antipsychotics and is associated with increased suicide and decreased adherence in patients with schizophrenia. However, no comprehensive review and network meta-analysis has been conducted to compare the efficacy of treatments for AIA.
OBJECTIVE
To compare the efficacy associated with AIA treatments.
DATA SOURCES
Three databases (MEDLINE, Web of Science, and Google Scholar) were systematically searched by multiple researchers for double-blind randomized clinical trials (RCTs) comparing active drugs for the treatment of AIA with placebo or another treatment between May 30 and June 18, 2023.
STUDY SELECTION
Selected studies were RCTs that compared adjunctive drugs for AIA vs placebo or adjunctive treatment in patients treated with antipsychotics fulfilling the criteria for akathisia, RCTs with sample size of 10 patients or more, only trials in which no additional drugs were administered during the study, and RCTs that used a validated akathisia score. Trials with missing data for the main outcome (akathisia score at the end points) were excluded.
DATA EXTRACTION AND SYNTHESIS
Data extraction and synthesis were performed, estimating standardized mean differences (SMDs) through pairwise and network meta-analysis with a random-effects model. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed.
MAIN OUTCOMES AND MEASURES
The primary outcome was the severity of akathisia measured by a validated scale at the last available end point.
RESULTS
Fifteen trials involving 492 participants compared 10 treatments with placebo. Mirtazapine (15 mg/d for ≥5 days; SMD, -1.20; 95% CI, -1.83 to -0.58), biperiden (6 mg/d for ≥14 days; SMD, -1.01; 95% CI, -1.69 to -0.34), vitamin B6 (600-1200 mg/d for ≥5 days; SMD, -0.92; 95% CI, -1.57 to -0.26), trazodone (50 mg/d for ≥5 days; SMD, -0.84; 95% CI, -1.54 to -0.14), mianserin (15 mg/d for ≥5 days; SMD, -0.81; 95% CI, -1.44 to -0.19), and propranolol (20 mg/d for ≥6 days; SMD, -0.78; 95% CI, -1.35 to -0.22) were associated with greater efficacy than placebo, with low to moderate heterogeneity (I2 = 34.6%; 95% CI, 0.0%-71.1%). Cyproheptadine, clonazepam, zolmitriptan, and valproate did not yield significant effects. Eight trials were rated as having low risk of bias; 2, moderate risk; and 5, high risk. Sensitivity analyses generally confirmed the results for all drugs except for cyproheptadine and propranolol. No association between effect sizes and psychotic severity was found.
CONCLUSIONS AND RELEVANCE
In this systematic review and network meta-analysis, mirtazapine, biperiden, and vitamin B6 were associated with the greatest efficacy for AIA, with vitamin B6 having the best efficacy and tolerance profile. Trazodone, mianserin, and propranolol appeared as effective alternatives with slightly less favorable efficacy and tolerance profiles. These findings should assist prescribers in selecting an appropriate medication for treating AIA.

Neurokinin 3 Receptor Antagonists Compared With Serotonin Norepinephrine Reuptake Inhibitors for Non-Hormonal Treatment of Menopausal Hot Flushes: A Systematic Qualitative Review.
INTRODUCTION
Hot flushes/flashes (HFs) or other vasomotor symptoms affect between 45 and 97% of women during menopause. Hormone replacement therapy (HRT) is effective at alleviating menopausal symptoms, but some women cannot or prefer not to take HRT. Since current non-hormonal options have suboptimal efficacy/tolerability, there is a pressing need for an effective, well-tolerated alternative. The neurokinin 3 receptor (NK3R) has recently been implicated in the generation of menopausal HFs and represents a novel therapeutic target to ameliorate HF symptoms. This review aims to assess if NK3R antagonists (NK3Ras) are more effective than Serotonin Norepinephrine Reuptake Inhibitors (SNRIs)-currently a common choice for non-hormonal treatment of menopausal HFs.
METHODS
Studies were identified after systematically searching Ovid MEDLINE and EMBASE databases based on PRISMA guidelines. Trial quality and bias were assessed. Key efficacy outcomes (HF frequency, HF severity and number of night-time awakenings/night-sweats) and selected safety outcomes were extracted and analysed.
RESULTS
Seven SNRI and four NK3Ra placebo-controlled randomised trials (plus four follow-up reports) were included in this review. NK3Ra administration resulted in a larger reduction from baseline in HF frequency, HF severity and night-sweats compared to SNRIs. Five of seven SNRI trials showed a reduction in HF frequency that was statistically significant (by 48-67% from baseline at weeks 8 or 12) whereas all NK3Ra trials showed a statistically significant reduction in HF frequency (by 62-93% from baseline at weeks 2, 4 or 12). While SNRI trials reported poor tolerability, particularly nausea, NK3Ra trials reported good tolerability overall, although two trials reported elevation in transaminases.
CONCLUSION
NK3Ras trials show encouraging efficacy and tolerability/safety. Completion of phase 3 NK3Ra trials are required to confirm efficacy and uphold safety/tolerability data but phase 2 results suggest that NK3Ras are more effective than SNRIs for non-hormonal treatment of menopausal HFs.

Meta-Analysis
INTRODUCTION
Few randomised controlled trials (RCTs) have directly compared long-acting muscarinic antagonist/long-acting β-agonist (LAMA/LABA) dual maintenance therapies for patients with chronic obstructive pulmonary disease (COPD). This systematic literature review and network meta-analysis (NMA) compared the efficacy of umeclidinium/vilanterol (UMEC/VI) versus other dual and mono-bronchodilator therapies in symptomatic patients with COPD.
METHODS
A systematic literature review (October 2015-November 2020) was performed to identify RCTs ≥ 8 weeks long in adult patients with COPD that compared LAMA/LABA combinations against any long-acting bronchodilator-containing dual therapy or monotherapy. Data extracted on changes from baseline in trough forced expiratory volume in 1 s (FEV), St George's Respiratory Questionnaire (SGRQ) total score, Transitional Dyspnoea Index (TDI) focal score, rescue medication use and moderate/severe exacerbation rate were analysed using an NMA in a frequentist framework. The primary comparison was at 24 weeks. Fixed effects model results are presented.
RESULTS
The NMA included 69 full-length publications (including 10 GSK clinical study reports) reporting 49 studies. At 24 weeks, UMEC/VI provided statistically significant greater improvements in FEV versus all dual therapy and monotherapy comparators. UMEC/VI provided similar improvements in SGRQ total score compared with all other LAMA/LABAs, and significantly greater improvements versus UMEC 125 μg, glycopyrronium 50 μg, glycopyrronium 18 μg, tiotropium 18 μg and salmeterol 50 μg. UMEC/VI also provided significantly better outcomes versus some comparators for TDI focal score, rescue medication use, annualised moderate/severe exacerbation rate, and time to first moderate/severe exacerbation.
CONCLUSION
UMEC/VI provided generally better outcomes compared with LAMA or LABA monotherapies, and consistent improvements in lung function (measured by change from baseline in trough FEV at 24 weeks) versus dual therapies. Treatment with UMEC/VI may improve outcomes for symptomatic patients with COPD compared with alternative maintenance treatments.

BACKGROUND AND OBJECTIVE
Changes in cannabis legalization regimes in several countries have influenced the diversification of cannabis use. There is an ever-increasing number of cannabis forms available, which are gaining popularity for both recreational and therapeutic use. From a therapeutic perspective, oral cannabis containing Δ-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) is a promising route of administration but there is still little information about its pharmacokinetics (PK) effects in humans. The purpose of this systematic review is to provide a general overview of the available PK data on cannabis and THC after oral administration.
METHODS
A search of the published literature was conducted using the PubMed database to collect available articles describing the PK data of THC after oral administration in humans.
RESULTS
The literature search yielded 363 results, 26 of which met our inclusion criteria. The PK of oral THC has been studied using capsules (including oil content), tablets, baked goods (brownies and cookies), and oil and tea (decoctions). Capsules and tablets, which mainly correspond to pharmaceutical forms, were found to be the oral formulations most commonly studied. Overall, the results reflect the high variability in the THC absorption of oral formulations, with delayed peak plasma concentrations compared to other routes of administration.
CONCLUSIONS
Oral THC has a highly variable PK profile that differs between formulations, with seemingly higher variability in baked goods and oil forms. Overall, there is limited information available in this field. Therefore, further investigations are required to unravel the unpredictability of oral THC administration to increase the effectiveness and safety of oral formulations in medicinal use.

We carried out a systematic review of published information on transfer of antiseizure medications (ASMs) into breastmilk, ASM serum concentrations in breastfed infants, and the wellbeing of infants breastfed by mothers on ASM treatment. Information was extracted from 85 relevant articles. No data on ASM levels in breastmilk or in breastfed infants was identified for cannabidiol, cenobamate, clobazam, eslicarbazepine-acetate, everolimus, felbamate, fenfluramine, retigabine, rufinamide, stiripentol, tiagabine, and vigabatrin. For ASMs, with available information on levels in breastfed infants, very low concentrations (in the order of 10% or less of maternal serum concentrations) were reported for carbamazepine, gabapentin, levetiracetam, oxcarbazepine, phenytoin, valproate, and clonazepam. Slightly higher levels (up to approximately 30% of maternal serum concentrations) have been observed with lamotrigine and topiramate, and in single case reports for brivaracetam, lacosamide, and perampanel. High infant levels (30% up to 100% of maternal serum concentrations) have been reported with ethosuximide, phenobarbital and zonisamide. Adverse infant effects during breastfeeding by mothers on ASMs appear to be rare regardless of the type of ASM, but systematic study is limited. Prospective long-term follow-up studies of developmental outcomes among children who have been breastfed by mothers taking ASMs are sparse and have mainly involved children whose mothers were taking carbamazepine, lamotrigine, levetiracetam, phenytoin or valproate as monotherapy while breastfeeding. Although these studies have not indicated poorer outcome among breastfed children compared with those who were not breastfed, further data on long-term outcomes are needed to draw firm conclusions. It is concluded that breastfeeding should in general be encouraged in women taking ASMs, given the well-established benefits of breastfeeding with regard to both short- and long-term infant health in the general population. Counselling needs to be individualized including information on the current knowledge regarding the woman's specific ASM treatment.

Meta-Analysis
BACKGROUND
Brivaracetam (BRV), cenobamate (CNB), eslicarbazepine acetate (ESL), lacosamide (LCM) and perampanel (PER) are antiseizure medications (ASMs) approved for adjunctive treatment of focal-onset seizures. So far, no randomised controlled trial directly compared the efficacy and safety of these drugs.
OBJECTIVE
We estimated the comparative efficacy and safety of these ASMs for the treatment of focal-onset seizures in adults with epilepsy using a network meta-analysis (NMA).
METHODS
We systematically searched (June week 4, 2021) MEDLINE (accessed by PubMed), the Cochrane Central Register of Controlled Trials (CENTRAL), and the US National Institutes of Health Clinical Trials Registry ( http://www.clinicaltrials.gov ). There were no date limitations or language restrictions. Randomised, double-blinded, controlled, parallel-group, add-on studies that compared oral BRV, CNB, ESL, LCM, and PER versus any comparator over maintenance periods of at least 12 weeks and included adult patients with focal seizures uncontrolled by concomitant ASMs were identified. The efficacy outcomes were the proportions of patients with ≥ 50% and 100% reduction in baseline seizure frequency during the maintenance period. The tolerability outcomes were the proportions of participants who experienced at least one treatment-emergent adverse event (TEAE) and experienced at least one TEAE leading to discontinuation. Effect sizes were estimated by network meta-analyses within a frequentist framework. The hierarchy of competing interventions was established using the surface under the cumulative ranking curve (SUCRA).
RESULTS
Sixteen trials (BRV: n = 3, CNB: n = 1, ESL: n = 4, LCM: n = 4, PER: n = 4) were included, overall enrolling 4507 patients randomised to add-on active treatments (BRV = 803, CNB = 221, ESL =9 90, LCM = 1104, and PER = 1389) and 2246 to add-on placebo. Cenobamate was associated with a higher rate of ≥ 50% seizure frequency reduction than BRV [odds ratio (OR) 2.02, 95% confidence interval (CI) 1.11-3.66], ESL (OR 1.93, 95% CI 1.07-3.48), LCM (OR 1.86, 95% CI 1.04-3.32), and PER (OR 2.07, 95% CI 1.16-3.70). There was a not statistically significant trend favouring CNB over ESL, LCM and PER for the seizure freedom outcome. Brivaracetam (OR 0.61, 95% CI 0.44-0.86) and LCM (OR 0.60, 95% CI 0.40-0.88) were associated with a lower proportion of participants experiencing TEAEs compared to ESL, and patients treated with PER were associated with a higher risk to experience at least one TEAE (OR 1.42, 95% CI 1.02-1.96) than BRV. According to SUCRA, CNB had the greatest likelihood of being the best option for the ≥ 50% and 100% seizure frequency reduction, and BRV and LCM had the highest probabilities of being the best-tolerated treatments.
CONCLUSIONS
Cenobamate ranked best for efficacy, and BRV and LCM were best tolerated over the other comparators. Although NMAs cannot replace direct comparisons, they may support physicians in clinical decision making.

Comparative Study Meta-Analysis
PURPOSE
To investigate the comparative effectiveness of dopamine agonists and monoamine oxidase type-B (MAO-B) inhibitors available for treatment of Parkinson's disease.
METHODS
We performed a systematic literature search identifying randomized controlled trials investigating 4 dopamine agonists (cabergoline, pramipexole, ropinirole, rotigotine) and 3 MAO-B inhibitors (selegiline, rasagiline, safinamide) for Parkinson's disease. We extracted and pooled data from included clinical trials in a joint model allowing both direct and indirect comparison of the seven drugs. We considered dopamine agonists and MAO-B inhibitors given as monotherapy or in combination with levodopa. Selected endpoints were change in the Unified Parkinson's Disease Rating Scale (UPDRS) score, serious adverse events and withdrawals. We estimated the relative effectiveness of each dopamine agonist and MAO-B inhibitor versus comparator drug.
RESULTS
Altogether, 79 publications were included in the analysis. We found all the investigated drugs to be effective compared with placebo when given as monotherapy except safinamide. When considering combination treatment, the estimated relative effects of selegiline, pramipexole, ropinirole, rotigotine, cabergoline, rasagiline and safinamide were 2.316 (1.819, 2.951), 2.091 (1.889, 2.317), 2.037 (1.804, 2.294), 1.912 (1.716, 2.129), 1.664 (1.113, 2.418), 1.584 (1.379, 1.820) and 1.179 (1.031, 1.352), respectively, compared with joint placebo and levodopa treatment.
CONCLUSIONS
Dopamine agonists were found to be effective as treatment for Parkinson's disease, both when given as monotherapy and in combination with levodopa. Selegiline and rasagiline were also found to be effective for treating Parkinson's disease, and selegiline was the best option in combination with levodopa among all the drugs investigated.

Cannabis and cannabinoids are often considered in the treatment of Parkinson's Disease (PD). The purpose of this paper was to perform a systematic review of the available data on cannabis treatment. We aimed to assess randomised trials as well as surveys among patients. We identified 569 papers on PD and cannabinoid treatment. Of these, there were only seven papers featuring randomised trials on the effects of different cannabinoids on PD. The results of these trials did not support the efficacy of cannabinoids in the treatment of motor signs of PD. Based on the available data, we conclude that there is currently insufficient data to support the administration of cannabinoids to PD patients. Larger, randomised studies of cannabis use in PD should be conducted.
