Article Synopsis
  • Zuranolone is a medication that affects GABA receptors in the brain and could influence activities that require focused thinking, like driving.
  • In a study involving 67 healthy adults, participants were given either zuranolone or a placebo, and their driving performance was measured using a simulator, focusing on how much the car swerved (standard deviation of lateral position, SDLP).
  • Results showed that zuranolone significantly impaired driving performance and cognitive abilities shortly after dosing, with effects persisting even after a week of treatment, highlighting the need for caution when prescribing the drug.

With the approval of the first CAR T-cell products for hematological malignancies in 2017, these autologous cell therapies have changed the treatment paradigm for patients with relapsed or refractory (r/r) non-Hodgkin lymphoma (NHL), who have a poor prognosis and few effective treatment options. Despite the demonstrated clinical benefit in patients with r/r diffuse large B-cell lymphoma, mantle cell lymphoma, and follicular lymphoma, many patients who are eligible for CAR T-cell therapies do not receive them or are treated with CAR T cells as a later line of therapy at advanced stages of disease. Several barriers exist for referring patients to an authorized treatment center (ATC) for CAR T-cell therapy.

N-methyl-D-aspartate ionotropic glutamatergic receptor (NMDAR) modulators, including rapastinel and ketamine, elicit rapid and sustained antidepressant responses in patients with treatment-resistant major depressive disorder. This phase I, randomized, multicenter, placebo-controlled, five-period, crossover, single-dose study evaluated simulated driving performance of healthy participants (N = 107) after single doses of rapastinel slow intravenous (i.v.

An impairment in next day driving performance has been reported for almost every drug currently United States Food and Drug Administration (FDA) approved for improvement of sleep in chronic and transient insomnia. Tasimelteon, a melatonin receptor agonist, demonstrated significant improvements in night-time sleep, daytime naps, and sleep timing in non-24-hr sleep-wake disorder (Non-24) by entraining these patients to a 24-hr day as measured by melatonin and cortisol rhythms. Given this new mechanism of action of entraining the biological clock, we conducted a study to evaluate the potential effect tasimelteon may have on the ability to operate a motor vehicle.

Objective: The objective of this study was to determine the next-day residual effects of acute and steady-state nighttime dosing of flibanserin on simulated driving performance and cognitive function in healthy premenopausal women.

Methods: In this randomized, double-blind, placebo-controlled, four-way crossover study, 72 subjects were treated with either acute oral doses of placebo, zopiclone 7.5 mg (positive control) or flibanserin 100 mg at bedtime (indicated therapeutic dose), or after chronic nightly oral doses of flibanserin 100 mg for 1 week followed by a single bedtime dose of flibanserin 200 mg (supratherapeutic dose).

Obesity, which has become epidemic throughout many parts of the world, is known to be a risk factor for a range of diseases including hypertension, diabetes, and vascular disease. Based on this review, it also appears that obesity is associated with increased crash risk and increased risk of serious or fatal injury in a crash. The problem is particularly an issue for commercial truck drivers.

Histaminergic neurons are regulators of the sleep-wake cycle. We evaluated the alerting effects of MK-7288 (10, 20 mg), a novel histamine-3 receptor inverse agonist (H3RIA), along with modafinil (200 mg), a standard treatment, in a randomized, double-blind, placebo controlled, crossover study of 56 patients with excessive daytime sleepiness (EDS). Efficacy was assessed using maintenance of wakefulness tests (MWT) and car driving simulation tests.

Study Objectives: Obstructive sleep apnea (OSA) has been associated with an increased risk of motor vehicle crashes. This driving risk can be reduced (≥ 50%) by treatment with continuous positive airway pressure (CPAP). However residual excessive daytime sleepiness (EDS) can persist for some patients who regularly use CPAP.

Background And Objective: Oxybutynin is a common antimuscarinic therapy for overactive bladder. Transdermally administered oxybutynin chloride topical gel 10% (OTG) has a low propensity for anticholinergic adverse effects and possibly also a low risk of cognitive impairment. A randomized, double-blind, placebo- and active-controlled study evaluated the effects of OTG on cognitive and psychomotor functions in older healthy adults.

Introduction: Psychotropic medication use is associated with weight gain. While there are studies and reviews comparing weight gain for psychotropics within some classes, clinicians frequently use drugs from different classes to treat psychiatric disorders.

Objective: To undertake a systematic review of all classes of psychotropics to provide an all encompassing evidence-based tool that would allow clinicians to determine the risks of weight gain in making both intra-class and interclass choices of psychotropics.

Overactive bladder (OAB) is a common condition, particularly in the elderly. Anticholinergic agents are the mainstay of pharmacological treatment of OAB; however, many anticholinergics can cross the blood-brain barrier (BBB) and may cause central nervous system (CNS) effects, including cognitive deficits, which can be especially detrimental in older patients. Many anticholinergics have the potential to cause adverse CNS effects due to muscarinic (M(1)) receptor binding in the brain.

What Is Already Known About This Subject: This study provides antimuscarinic agents for overactive bladder (OAB) display variable association with side effects mediated by the central nervous system (CNS), which may be of particular concern in the elderly. Adverse effects on CNS functioning are related to muscarinic receptor subtype selectivity and the ability of the agent to cross the blood-brain barrier, where P-gp plays a role in limiting permeability.

What This Study Adds: This study provides a parallel investigation of CNS penetration of antimuscarinic OAB agents in vivo and assessment of physical properties and permeability in cell monolayers in vitro.
