Akeem Yusuf, Victoria Chia, Fei Xue, Daniel D Mikol, Lisa Bollinger, Charles Cangialose
PURPOSE: The recent expansion of electronic health and medical record systems may present an opportunity to generate robust post-approval safety data and obviate the limitations of prospective pregnancy exposure registries. We examined and compared, over the same time frame, the outcomes of triptan exposure in pregnancy using (1) a retrospective claims database and (2) a previously completed pregnancy registry. METHODS: Using the Marketscan database, the risk of major birth defects was ascertained in live-born infants whose birth mothers were exposed to sumatriptan, naratriptan, or sumatriptan/naproxen during pregnancy...

PURPOSE: The safety of nonsteroidal anti-inflammatory drugs (NSAIDs) commonly used in Asia-Pacific countries has had limited study. We assessed the risk of hospitalization for gastrointestinal events with loxoprofen and mefenamic acid compared with other NSAIDs in Asia-Pacific populations. METHODS: We conducted a cohort study using a distributed network with a common data model in Australia, Hong Kong, Japan, Korea, and Taiwan. We included patients who initiated diclofenac, loxoprofen, mefenamic acid, or celecoxib and followed them until their first gastrointestinal hospitalization, switch or discontinuation of medication, disenrollment, or end of database coverage...

PURPOSE: Signal evaluation is considered to be a tedious process owing to the large number of disproportional signals detected. This study aimed to apply a biclustering algorithm in the spontaneous reporting system of China and to obtain the optimal parameters. The biclustering algorithm is expected to improve the efficiency of signal evaluation by identifying similar signal groups. METHODS: Information component (IC) was the method used for disproportionality analysis...

PURPOSE: Drug side effects often lead to serious outcomes. Administration of second-generation antipsychotics has resulted in diabetic ketoacidosis and diabetic coma leading to death. Therefore, pharmacists are required to collect information on clinical test values, determine the appropriate test timing, and coordinate with doctors for further clinical laboratory orders, all of which are labor-intensive and time-intensive tasks. In this study, we developed a side effect-monitoring tool and aimed to clarify the influence and efficiency of monitoring side effects by using the tool in patients taking atypical antipsychotics in whom it is necessary to check clinical test values such as blood sugar levels...

PURPOSE: Estimating the rate of adverse events (AEs) caused by a treatment in clinical trials typically involves comparing the proportions of patients experiencing AEs in intervention and control groups. However, potentially important information, including duration, recurrence, and intensity of events, is lost. In this study, we illustrate how the additional information can be obtained and incorporated into analyses of AEs. METHODS: Data on psychiatric AEs were extracted from clinical study reports (CSRs) provided by the manufacturer of oseltamivir in 4 prophylaxis randomised trials in adults and adolescents...

PURPOSE: Little is known about the longitudinal patterns of buprenorphine adherence among pregnant women with opioid use disorder, especially when late initiation, nonadherence, or early discontinuation of buprenorphine during pregnancy may increase the risk of adverse outcomes. We aimed to identify distinct trajectories of buprenorphine use during pregnancy, and factors associated with these trajectories in Medicaid-enrolled pregnant women. METHODS: A retrospective cohort study included 2361 Pennsylvania Medicaid enrollees aged 15 to 46 having buprenorphine therapy during pregnancy and a live birth between 2008 and 2015...

PURPOSE: The purposes of the study are to compare safety specifications between Japan and the European Union (EU) and to identify the factors affecting categorization of important identified or potential risks. METHODS: Safety specifications were collected from orphan and nonorphan drugs approved in Japan between 2014 and 2016, and in the EU as of October 2017. Outcome was defined dichotomously as listed as important identified risks or potential risks. A mixed-effects logistic regression was performed to estimate odds ratios of being listed as important identified risks...

PURPOSE: In October 2014, the US Drug Enforcement Agency moved hydrocodone combination products (HCPs) from schedule III to II of the Controlled Substances Act, further restricting their access. The aim of the study is to quantify the effect of hydrocodone's "upscheduling" on the use of opioid and nonopioid analgesics among chronic users. METHODS: Using IQVIA LRx LifeLink anonymized pharmacy data 2013 to 2015, we performed interrupted time series analysis and group-based trajectory modeling to characterize the effect of rescheduling on 316 731 long-term hydrocodone users...

PURPOSE: To estimate causation of adverse drug reaction (ADR) reports, causality methods were developed from a theoretical perspective. In daily practice, not all information is relevant or available, decreasing the applicability. We developed a new causality documentation tool (CausDoc) where an algorithm is combined with expert judgement. The aim of this study is to test the validity and reliability of CausDoc for ADR reports on drugs and vaccines. METHODS: CausDoc provides 9 structured relevant questions...

INTRODUCTION: In May 2008, the Food and Drug Administration launched the Sentinel Initiative, a multi-year program for the establishment of a national electronic monitoring system for medical product safety that led, in 2016, to the launch of the full Sentinel System. Under the Mini-Sentinel pilot, several algorithms for identifying health outcomes of interest, including one for anaphylaxis, were developed and evaluated using data available from the Sentinel common data model. PURPOSE: To evaluate whether features extracted from unstructured narrative data using natural language processing (NLP) could be used to classify anaphylaxis cases...

PURPOSE: Leukotriene receptor antagonists are used in asthma and rhinitis treatment. Pharmacovigilance data have suggested an association between montelukast and depression, but the association has not been established in controlled study designs. We described the association between initiation of montelukast and depression, using prescriptions of antidepressants as a surrogate marker, and assessed whether the association was related to the underlying asthma disease. METHODS: We performed a symmetry analysis, with a study period from January 1, 2000 to December 31, 2016, using 3 nationwide Danish registers...

PURPOSE: Hypomagnesaemia has been associated with various adverse outcomes. Loop and thiazide diuretics promote urinary magnesium excretion. However, it is unknown if this links to hypomagnesaemia. We study if loop or thiazide diuretic use affects serum magnesium levels and if it associates with hypomagnesaemia. In addition, we study the effect of combining a potassium-sparing diuretic with a thiazide diuretic on the presence of hypomagnesaemia. METHODS: The study performed a cross-sectional analysis within 9820 participants from the prospective Rotterdam Study...
