However, several studies have shown an association between ASMs and an increased risk of hematological disorders, such as thrombocytopenia, aplastic anemia, and platelet function disorders leading to prolonged bleeding times. This review explores the existing literature on this topic, investigating a wide variety of ASMs, ranging from first-generation medications to newer ones. A comprehensive search was conducted on all the currently approved ASMs using PubMed and Google Scholar: review articles, clinical trials, meta-analysis, observational studies, case reports, and relevant animal studies were identified. We extracted 15 ASMs including valproic acid (VPA), carbamazepine, phenytoin, phenobarbital, diazepam, clonazepam, lamotrigine, levetiracetam, oxcarbazepine, felbamate, topiramate, pregabalin, lacosamide, cannabidiol (CBD), and perampanel that contain considerable literature regarding different coagulopathies. An in-depth review of over 140 studies revealed a robust association between ASM-induced changes and the onset of bleeding disorders via several different mechanisms. Polytherapy, the use of multiple ASMs, also emerged as a significant risk factor for the development of coagulopathies. This review highlights the potential link between ASMs and bleeding disorders, emphasizing the importance of considering this risk during treatment planning. By understanding these associations, healthcare providers can optimize patient outcomes and minimize bleeding risks. Additionally, this review identifies the need for further research to bridge current knowledge gaps in clinical pharmacology related to ASMs and bleeding disorders.</p>","PeriodicalId":11282,"journal":{"name":"Drugs - Real World Outcomes","volume":" ","pages":"1-15"},"PeriodicalIF":1.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11829880/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142920313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In month 6 pre-index, mean number of MH-related disability days was 1.7 in the esketamine cohort, 1.2 in the TMS cohort, 1.3 in the ECT cohort, and 0.8 in the SGA augmentation cohort; mean MH-related disability costs were US $443 in the esketamine cohort, US $339 in the TMS cohort, US $178 in the ECT cohort, and US $143 in the SGA augmentation cohort.

Inadequate response may indicate non-adherence, which is associated with an increased risk of cardiovascular events and increased costs. Group-based trajectory modeling is an approach to establish probabilistic developmental trajectories of adherence, differentiating individuals by their distinct longitudinal medication-taking behaviors. We examined whether lipid testing is associated with distinct trajectories of statin adherence among individuals enrolled in a Medicare fee-for-service plan in the USA.</p><p><strong>Methods: </strong>A retrospective cohort study was conducted using the Centers for Medicare & Medicaid Chronic Condition Warehouse 5% sample of Medicare fee-for-service data between 2006 and 2015. Statin use and lipid testing were identified using claims data. The proportion of days covered was calculated for each 30 days after the index date, which was used to estimate the probability of belonging to each potential adherence trajectory.</p><p><strong>Results: </strong>In a cohort of 138,101 statin initiators, four statin adherence trajectory groups were identified. The four groups were differentiated as \"rapid decline\" (21.53%), \"gradual decline\" (10.25%), \"decline first then improve later\" (26.47%), and \"high adherence\" (41.75%). Compared with \"high adherence,\" initiators who had lipid tests within 360 days after statin initiation were less likely to fall into \"rapid decline\" (adjusted odds ratio: 0.661; 95% confidence interval 0.641-0.683), \"gradual decline\" (adjusted odds ratio: 0.834; 95% confidence interval 0.801-0.868), and \"decline first then improve later\" groups (adjusted odds ratio: 0.936; 95% confidence interval 0.910-0.962).</p><p><strong>Conclusions: </strong>Lipid testing is positively associated with greater use of statin medication across different adherence trajectories in the present study.</p>","PeriodicalId":11282,"journal":{"name":"Drugs - Real World Outcomes","volume":" ","pages":"75-81"},"PeriodicalIF":1.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11829858/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142871664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
