There is an urgent need to address the devastating pandemic, COVID‐19, caused by SARS‐CoV‐2. The efforts to understand the details of this disease in hope of providing effective treatments are commendable. It is clear now that the virus can cause far more damage in patients with comorbid conditions—particularly in those with respiratory, cardiovascular, or immune‐compromised system—than in patients without such comorbidities. Drug use can further exacerbate the condition. In this regard, the ill effects of smoking are amply documented, and no doubt can be a confounding factor in COVID‐19 progression. Although conflicting hypotheses on the potential role of nicotine in COVID‐19 pathology have recently been offered, we believe that nicotine itself, through its interaction with the nicotinic cholinergic system, as well as ACE2, may not only be of use in a variety of neuropsychiatric and neurodegenerative diseases, but may also be of potential use in COVID‐19. Thus, on one hand, while we strongly support smoking cessation as a means of harm reduction associated with COVID‐19, on the other hand, we support a potential therapeutic role for nicotine, nicotinic agonists, or positive allosteric modulators of nicotinic cholinergic receptors in COVID‐19, owing to their varied effects including mood regulation, anti‐inflammatory, and purported interference with SARS‐CoV‐2 entry and/or replication.

COVID-19 中的尼古丁和尼古丁胆碱能系统。

迫切需要解决由 SARS-CoV-2 引起的毁灭性大流行病 COVID-19。努力了解这种疾病的细节以期提供有效的治疗是值得称赞的。现在很清楚,与没有这些合并症的患者相比,该病毒对患有合并症的患者(尤其是呼吸系统、心血管系统或免疫系统受损的患者)造成的损害要大得多。吸毒会进一步加重病情。在这方面,吸烟的不良影响已得到充分证明,无疑可能是 COVID-19 进展的一个混杂因素。尽管最近提出了关于尼古丁在 COVID-19 病理学中的潜在作用的相互矛盾的假设,但我们认为尼古丁本身,通过其与烟碱胆碱能系统以及 ACE2 的相互作用,可能不仅可用于各种神经精神疾病和神经退行性疾病,还可能在 COVID-19 中具有潜在用途。因此,一方面,虽然我们强烈支持将戒烟作为一种减少与 COVID-19 相关的危害的手段,但另一方面,我们支持烟碱、烟碱激动剂或烟碱胆碱能受体的正变构调节剂的潜在治疗作用。 COVID-19,因为它们具有多种作用,包括情绪调节、抗炎和据称干扰 SARS-CoV-2 进入和/或复制。
