These inflammatory conditions of the central nervous system (CNS) may have serious and devastating consequences if not treated adequately. In this review, we first summarize how neurotropic viruses can enter the CNS by (1) crossing the blood-brain barrier or blood-cerebrospinal fluid barrier; (2) invading the nose via the olfactory route; or (3) invading the peripheral nervous system. Neurotropic viruses may then enter the intracellular space of brain cells via endocytosis and/or membrane fusion. Antiviral drugs are currently used for different viral CNS infections, even though their use and dosing regimens within the CNS, with the exception of acyclovir, are minimally supported by clinical evidence. We therefore provide considerations to optimize drug treatment(s) for these neurotropic viruses. Antiviral drugs should cross the blood–brain barrier/blood cerebrospinal fluid barrier and pass the brain cellular membrane to inhibit these viruses inside the brain cells. Some antiviral drugs may also require intracellular conversion into their active metabolite(s). This illustrates the need to better understand these mechanisms because these processes dictate drug exposure within the CNS that ultimately determine the success of antiviral drugs for CNS infections. Finally, we discuss mathematical model-based approaches for optimizing antiviral treatments. Thereby emphasizing the potential of CNS physiologically based pharmacokinetic models because direct measurement of brain intracellular exposure in living humans faces ethical restrictions. Existing physiologically based pharmacokinetic models combined with in vitro pharmacokinetic/pharmacodynamic information can be used to predict drug exposure and evaluate efficacy of antiviral drugs within the CNS, to ultimately optimize the treatments of CNS viral infections.</p>","PeriodicalId":10508,"journal":{"name":"CNS drugs","volume":"28 1","pages":""},"PeriodicalIF":6.0,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140561208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, inadequate analgesia during the procedure remains a concern, prompting the search for a medication that can provide optimal pain control with minimal impact on the respiratory and circulatory systems.&lt;/p&gt;&lt;h3 data-test=\"abstract-sub-heading\"&gt;Objectives&lt;/h3&gt;&lt;p&gt;The aim of this study was to observe the effects of different doses of esketamine combined with dexmedetomidine on reducing visual analog scale (VAS) scores during surgical interventions.&lt;/p&gt;&lt;h3 data-test=\"abstract-sub-heading\"&gt;Methods&lt;/h3&gt;&lt;p&gt;One hundred two patients who underwent PETD were randomly divided into a control group (group C: normal saline + dexmedetomidine), an E1 group (0.1 mg kg&lt;sup&gt;−1&lt;/sup&gt; esketamine + dexmedetomidine), and an E2 group (0.2 mg kg&lt;sup&gt;−1&lt;/sup&gt; esketamine + dexmedetomidine). The primary outcome was the maximum visual analogue scale (VAS) (score: 0 = no pain and 10 = worst pain) at six time points. The secondary outcomes included the Assessment of Alertness/Sedation Scale (OAA/S) score and mean arterial pressure (BP), heart rate (HR), respiratory rate (RR), and oxygen saturation (SpO&lt;sub&gt;2&lt;/sub&gt;) at 11 time points. The incidence of adverse reactions during and 24 h after the operation and patient satisfaction with the anesthesia were also recorded.&lt;/p&gt;&lt;h3 data-test=\"abstract-sub-heading\"&gt;Results&lt;/h3&gt;&lt;p&gt;Compared with those in group C, the VAS scores of patients in groups E1 and E2 were lower at &lt;i&gt;T&lt;/i&gt;&lt;sub&gt;6&lt;/sub&gt;, &lt;i&gt;T&lt;/i&gt;&lt;sub&gt;7&lt;/sub&gt;, and &lt;i&gt;T&lt;/i&gt;&lt;sub&gt;9&lt;/sub&gt; (&lt;i&gt;P&lt;/i&gt; &lt; 0.05). From &lt;i&gt;T&lt;/i&gt;&lt;sub&gt;4&lt;/sub&gt; to &lt;i&gt;T&lt;/i&gt;&lt;sub&gt;10&lt;/sub&gt;, the OAA/S scores of the E1 and E2 groups were both lower than those of group C (&lt;i&gt;P&lt;/i&gt; &lt; 0.05), and at the &lt;i&gt;T&lt;/i&gt;&lt;sub&gt;4&lt;/sub&gt;–&lt;i&gt;T&lt;/i&gt;&lt;sub&gt;6&lt;/sub&gt; time points, the OAA/S score of the E2 group was lower than that of group E1 (&lt;i&gt;P&lt;/i&gt; &lt; 0.05). At &lt;i&gt;T&lt;/i&gt;&lt;sub&gt;4&lt;/sub&gt; and &lt;i&gt;T&lt;/i&gt;&lt;sub&gt;5&lt;/sub&gt;, the HR and BP of patients in groups E1 and E2 were greater than those in group C (&lt;i&gt;P&lt;/i&gt; &lt; 0.05). Compared with those in group C, the incidences of intraoperative illusion, floating sensation, postoperative dizziness, and hyperalgesia in groups E1 and E2 were significantly greater (&lt;i&gt;P&lt;/i&gt; &lt; 0.01). There was no significant difference in patient RR, SpO&lt;sub&gt;2&lt;/sub&gt;, or postoperative satisfaction with anesthesia among the three groups (&lt;i&gt;P&lt;/i&gt; &gt; 0.05).&lt;/p&gt;&lt;h3 data-test=\"abstract-sub-heading\"&gt;Conclusion&lt;/h3&gt;&lt;p&gt;The combination of esketamine and dexmedetomidine can reduce VAS scores during certain stages of this type of surgery; it has minimal impact on respiration and circulation.

The gut microbiota can influence levodopa kinetics, and conversely, drugs administered for PD can influence gut microbiota composition. Through a two-step enzymatic pathway, gut microbes can decarboxylate levodopa to dopamine in the small intestine and then dehydroxylate it to <em>m</em>-tyramine, thus reducing availability. Inhibition of bacterial decarboxylation pathways could therefore represent a strategy to increase levodopa absorption. Other bacterial perturbations common in PD, such as small intestinal bacterial overgrowth and <em>Helicobacter pylori</em> infection, can also modulate levodopa metabolism, and eradication therapies may improve levodopa absorption. Interventions targeting the gut microbiota offer a novel opportunity to manage disabling motor complications and dopa-unresponsive symptoms. Mediterranean diet-induced changes in gut microbiota composition might improve a range of non-motor symptoms. Prebiotics can increase levels of short-chain fatty acid-producing bacteria and decrease pro-inflammatory species, with positive effects on clinical symptoms and levodopa kinetics. Different formulations of probiotics showed beneficial outcomes on constipation, with some of them improving dopamine levels; however, the most effective dosage and duration and long-term effects of these treatments remain unknown. Data from faecal microbiota transplantation studies are preliminary, but show encouraging trends towards improvement in both motor and non-motor outcomes.</p> <p>This article summarises the most up-to-date knowledge in pharmacomicrobiomics in PD, and discusses how the manipulation of gut microbiota represents a potential new therapeutic avenue for PD.</p>","PeriodicalId":10508,"journal":{"name":"CNS drugs","volume":"144 1","pages":""},"PeriodicalIF":6.0,"publicationDate":"2024-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140561028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
