Anxiety is a common neuropsychiatric disorder which affects both physical and mental health. Complex neurobiological mechanisms are involved in the genesis of anxiety, and the drugs used to date, though effective, are not free from shortcomings. Conventional agents like the classical benzodiazepines and the atypical nonbenzodiazepine agents like buspirone have their own limitations. There is thus need to explore newer neurochemical pathways to develop efficacious and safer drugs for the disorder. Nitric oxide (NO) is a unique neuromodulator substance, with the ability to influence and modulate several other conventional messengers which play an important role in anxiety...

The classic high-dose narcotic-based cardiac anesthetic has been modified to facilitate a fast-track, rapid recovery in the intensive care unit (ICU). Postoperative sedation is consequently now an essential component in recovery of the patient undergoing cardiac surgery. It must facilitate the patient's unawareness of the environment as well as reduce the discomfort and anxiety caused by surgery, intubation, mechanical ventilation, suction, and physiotherapy. Benzodiazepines seem well suited for this role, but propofol, opioids, and dexmedetomidine are among other agents commonly used for sedation in the ICU...

Several major medical and psychiatric organizations, including the American Geriatrics Society, advise against using benzodiazepines or nonbenzodiazepine hypnotics in older adults. Despite these recommendations, benzodiazepines continue to be massively prescribed to a group with the highest risk of serious adverse effects from these medications. This article summarizes legitimate reasons for prescribing benzodiazepines in the elderly, serious associated risks of prescribing them, particularly when not indicated, barriers physicians encounter in changing their prescription patterns, and evidence-based strategies on how to discontinue benzodiazepines in older patients...

STUDY OBJECTIVES: We sought to determine whether nonbenzodiazepine sedative hypnotics (NBSH) reduce the occurrence of the low arousal threshold (LAT) phenotype. METHODS: Consecutive patients with suspected obstructive sleep apnea (OSA) referred for polysomnography (PSG) had demographic and PSG data abstracted. LAT was estimated using PSG criteria. After adjusting for pretest probability (PTP) for OSA, we calculated the effect that premedication with NBSHs has on LAT prevalence...

We describe the care for an elderly woman who was admitted to the intensive care unit (ICU) to receive noninvasive ventilation for acute exacerbation of chronic obstructive pulmonary disease. After administration of the sleeping pill zopiclone, a nonbenzodiazepine receptor agonist (NBRA), the patient became agitated and was confused, a possible paradoxical reaction to benzodiazepines. These symptoms were immediately resolved after treatment with flumazenil, usually used to reverse the adverse effects of benzodiazepines or NBRAs and to reverse paradoxical reactions to benzodiazepines...

The Beers Criteria identifies potentially inappropriate medications for patients who are 65 years of age and older. Initially published in 1991, the criteria have been updated multiple times, most recently in 2015. The Beers Criteria is a tool designed to alert health-care providers to the potential harms of specific medications so they may better tailor therapeutic regimens for their elderly patients. The expert panel of the 2015 update made changes to a number of previous recommendations and provided 2 new tables on select drug interactions and select medications requiring renal dose adjustments...

Insomnia, a highly prevalent disorder, can be detrimental to patients' overall health and worsen existing comorbidities. Patients may have acute episodes of insomnia related to a traumatic event, but more commonly insomnia occurs chronically. While proper sleep hygiene and behavioral therapy play important roles in the nonpharmacologic management of short-term and chronic insomnia, medications may also be required. Historically, insomnia has been treated with agents such as benzodiazepines, nonbenzodiazepine receptor agonists, and melatonin agonists...

Pain is an emotion and neuropathic pain symptoms are modulated by supraspinal structures such as the amygdala. The central nucleus of the amygdala is often called the 'nociceptive amygdala', but little is known about the role of the basolateral amygdala. Here, we monitored the mechanical nociceptive thresholds in a mouse model of neuropathic pain and infused modulators of the glutamate/GABAergic transmission in the basolateral nucleus of the amygdala (BLA) via chronically-implanted cannulas. We found that an N-methyl-D-aspartate-type glutamate receptor antagonist (MK-801) exerted a potent antiallodynic effect, whereas a transient allodynia was induced after perfusion of bicuculline, a GABA(A) receptor antagonist...

Pain and agitation may be difficult to assess in a critically ill patient. Pain is best assessed by self-reporting pain scales; but in patients who are unable to communicate, behavioral pain scales seem to have benefit. Patients' sedation level should be assessed each shift and preferably by a validated ICU tool, such as the RASS or SAS scale. Pain is most appropriately treated with the use of opiates, and careful consideration should be given to the pharmacokinetic and pharmacodynamic properties of various analgesics to determine the optimal agent for each individual patient...

In rehabilitation, nurses are the first team members to note or be told when a patient is having a positive or negative response to a medication. In brain injury medicine, medications are often used to augment cognitive or physical rehabilitation by increasing alertness, attention, focus, concentration, improving sleep, decreasing agitation, or easing spasticity and rigidity. Rehabilitation nurses not only should be aware of how medications work but also how medications may work differently in a chronically ill or disabled population...

Andrew D Krystal
Research into the sleep-wake cycle has provided new treatment targets for patients with insomnia as well as a better understanding of how medications affect sleep processes. Current insomnia medications, including benzodiazepines and nonbenzodiazepines, focus on enhancing sleep-promoting systems through broad antagonism of GABA. Other medications that promote sleep by blocking wake-promoting systems include antidepressants, antipsychotics, and antihistamines, but adverse effects and nonspecific therapeutic effects limit their use...
