This study examined the association between delirium and the subsequent monthly use of anticholinergic, sedative, and opioid medications in the 1 year after delirium in older adults with AD.MethodsThis comparative interrupted time series analysis involved adults (aged 65 years and older) with a diagnosis of AD initiating on cholinesterase inhibitors (ChEIs) based on 2013–2017 Medicare data. Separate patient‐level segmented regression models were used for each outcome to evaluate changes in the cumulative anticholinergic burden (CAB), sedative load, and opioid load after the delirium/index event using a 12‐month baseline and follow‐up period among patients who had a delirium event and those without delirium (control group). Propensity score‐based stabilized weights were utilized to balance baseline factors in the delirium and control groups.ResultsThe study included 80,019 older adults with AD with incident ChEI use; 17.11% had delirium. There was an immediate decline in monthly CAB after the delirium event (mean estimate −0.86, <jats:italic>p</jats:italic>‐value: 0.01) compared to the control group. A similar decline was observed when examining the sedative load (−0.06, <jats:italic>p</jats:italic>‐value: 0.002) after the delirium event. However, there was no decline in opioid load (−0.50, <jats:italic>p</jats:italic>‐value: 0.18). In the long term, CAB (0.13; <jats:italic>p</jats:italic>‐value: <0.0001), sedative load (0.01; <jats:italic>p</jats:italic>‐value: <0.001), and opioid load (0.07; <jats:italic>p</jats:italic>‐value: 0.006) increased over the 1‐year post‐delirium period in the delirium group compared to those without delirium.ConclusionThis study found the burden of deliriogenic medications over the 1‐year follow‐up showed increasing trends in older adults with AD, even though there was some level shift in CAB and sedative load after the delirium event.","PeriodicalId":20013,"journal":{"name":"Pharmacotherapy","volume":null,"pages":null},"PeriodicalIF":4.1,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142248752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional management strategies, including dietary, exercise, and behavioral interventions, often result in insufficient and unsustainable weight loss. Lifestyle modification remains the cornerstone of obesity management, providing the foundation for other strategies. While options such as bariatric surgery remain an effective intervention for severe obesity, it is associated with its own set of risks and is typically reserved for patients who have not achieved the desired results with pharmacotherapy and lifestyle interventions. Incretin hormone agonists represent a significant advancement in the pharmacotherapy of obesity, offering substantial weight reduction and cardiometabolic benefits. Agents like liraglutide, semaglutide, and tirzepatide supported by key clinical trials such as Satiety and Clinical Adipose Liraglutide Evidence (SCALE), Semaglutide Treatment Effect in People with Obesity (STEP) program trials, and Tirzepatide Once Weekly for the Treatment of Obesity (SURMOUNT-1) have demonstrated remarkable efficacy in promoting weight loss and improving metabolic outcomes. Additionally, novel therapies, including dual and triple incretin agonists, are under investigation and hold the potential for further advancements in obesity treatment. These novel therapies can be categorized by their mechanisms of action and route of administration into oral glucagon-like peptide-1 (GLP-1) receptor agonists, triple agonists (targeting GLP-1, glucose-dependent insulinotropic polypeptide [GIP], and glucagon receptors), and glucagon receptor-GLP-1 receptor co-agonists. Other innovative approaches include oral GIP-GLP-1 receptor co-agonists, and the combination of long-acting amylin receptor agonists with GLP-1 receptor agonists. The ongoing development of incretin-based therapies and the expanding availability of currently available agents are expected to enhance clinical outcomes further and reduce the burden of obesity-related health complications.

However, there are significant drug-drug interactions (DDI) between LTG and combined drugs such as carbamazepine (CBZ) and valproic acid (VPA). It is particularly important to consider the risk of DDI in combination therapy for intractable epilepsy in pediatric patients. Therefore, it is necessary to adjust the dosage of LTG accordingly. The aim of this study was to establish and validate a pediatric physiologically based pharmacokinetic (PBPK) model for predicting LTG exposure.
