It is likely that both shear stress on the endothelial cells, transmural pressure and smooth muscle cell tone are important for the altered vascular structure. However, the precise interaction and importance of these factors are incompletely understood. At the molecular level transglutaminases, metalloproteinases, integrins, NO and several other factors have been suggested to be important, but our understanding of how the many factors together control vascular structure is surprisingly limited. The media–lumen diameter ratio of the small arteries has prognostic value, which is independent of the classical risk factors for cardiovascular disease. Importantly this is also the case in patients treated pharmacologically for high blood pressure. It is therefore relevant to consider small artery structure as a potential target in relation to prevention of cardiovascular disease.</p>","PeriodicalId":8733,"journal":{"name":"Basic & Clinical Pharmacology & Toxicology","volume":"136 2","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/bcpt.14127","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142977428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted a single interrupted time series analysis on the monthly cumulative incidence of nonvitamin K antagonist oral anticoagulants (NOAC), warfarin, or heparins, before and after March 2020, using SCIFI-PEARL dataset. For anticoagulants in total, there were no statistically significant changes or differences in the trends of initiation after the start of the pandemic. There was a slight numerical decrease in initiation after the onset of the pandemic, particularly for NOACs. For individuals aged ≥ 65 years, however, the immediate decrease in initiation was considerable for NOACs. The prepandemic declining trend of warfarin initiation seemed to attenuate, that is, became less negative, after March 2020. We did not find any profound effect of the COVID-19 pandemic on the initiation of anticoagulants in total.

Products are also available in which CBN is combined with conventional therapies, with a common product containing both CBN and the widely used sleep-aid melatonin. The combination of CBN and melatonin provides potential for a pharmacokinetic drug–drug interaction (DDI) given that cannabinoids are known to inhibit drug-metabolizing enzymes. Indeed, we recently reported that CBN potently inhibited the CYP1A2-mediated metabolism of caffeine. CYP1A2 is the major hepatic enzyme involved in the metabolism of melatonin; thus, in this study, we aimed to examine whether CBN inhibited CYP1A2-mediated metabolism of melatonin in vitro and in vivo. We found CBN potently inhibited CYP1A2-mediated metabolism of melatonin and increased the apparent oral bioavailability of melatonin in mice with a four-fold increase in the plasma melatonin exposure.
