Background: Drug-induced interstitial lung disease (DIILD) is a severe adverse event leading to morbidity and mortality. This study evaluated the adverse event indicators of DIILD and time-to-onset profiles following the daily intake of herbal drugs (Scutellariae radix ["ogon" in Japanese], Bupleuri radix ["saiko" in Japanese], and Pinelliae tuber ["hange" in Japanese]) using the Japanese Adverse Drug Event Report database. DIILD was defined in accordance with the Medical Dictionary for Regulatory Activities.

The purpose of this study was to identify platelet aggregation inhibitors (PAIs) that contribute to high drug costs and are sold as brand-name drugs in order to increase the usage rate of generic drugs, and to analyze the factors that affect the usage rate of generic drug.

This study aimed to comprehensively analyze extravasation risk, skin injury profiles, and outcomes for suspect drugs from the Japanese Adverse Drug Event Report (JADER) database. Adverse events were defined according to the Medical Dictionary for Regulatory Activities/Japanese version; the term extravasation (Standardized MedDRA Query Code: 20000136) was used in this analysis.

This study analyzes the correlation between generic drug usage and monthly personal income by examining prescriptions for individual drugs.
Methods: We conducted a cross-sectional study based on the data set from the National Database of Health Insurance Claims and Specific Health Checkups of Japan Open Data Japan and the Basic Survey on Wage Structure.
Purpose: Osteoporosis is an adverse event of prednisolone. This study aimed to assess prednisolone-induced osteoporosis (PIO) profiles and patient backgrounds by analyzing data from the Japanese Adverse Drug Event Report (JADER) database.
Methods: The current study focused only on orally administered prednisolone.
Background: Medication-related osteonecrosis of the jaw is a serious adverse event associated with bone-modifying agents, such as injectable bisphosphonate (zoledronic acid) and the anti-receptor activator of nuclear factor-κB ligand antibody (denosumab).
Objective: This study aims to evaluate and compare the time-to-onset profile for medication-related osteonecrosis of the jaw associated with denosumab between treatment-naïve (naïve group) and pre-treatment with zoledronic acid (post-zoledronic acid group) patients using the Japanese Adverse Drug Event Report database.
Methods: Medication-related osteonecrosis of the jaw was defined according to the Medical Dictionary for Regulatory Activities.
Purpose: The aim of our study was to assess the clinical features of hand-foot syndrome (HFS) associated with certain systemic chemotherapeutic drugs in a real-world setting using the Japanese Adverse Drug Event Report (JADER) database.
Methods: HFS was defined using the preferred terms from the Medical Dictionary for Regulatory Activities. We used several indices, such as the reporting odds ratios (RORs) at 95% confidence interval (CI), the time-to-onset profile of HFS, and cluster analysis.
Background: Acute kidney injury (AKI) is associated with significant increases in short- and long-term morbidity and mortality. Drug-induced AKI is a major concern in the present healthcare system. Our spontaneous reporting system (SRS) analysis assessed links between AKI, along with patients' age, as healthcare-associated risks and administered anti-infectives.

Using the preferred terms and standardized queries from the Medical Dictionary for Regulatory Activities, we calculated the reporting odds ratios (RORs). We extracted GEN-associated genes (seed genes) and analyzed drug-gene interactions using the ClueGO plug-in in the Cytoscape software and the DIseAse MOdule Detection (DIAMOnD) algorithm.

We evaluated the onset profile of DIGs (DIGO and DIGP) associated with prescription drugs by analyzing data in the Japanese Adverse Drug Event Report (JADER) database. We selected 161 DIG-related drugs and categorized them into 19 classes based on the Anatomical Therapeutic Chemical (ATC) Classification System.

The aim of this study was to evaluate the relationship between anticancer agents and CIPN development using data from the Japanese Adverse Drug Event Report (JADER) database and to characterize the time-to-onset and outcomes of CIPN. Chemotherapy-induced peripheral neuropathy was defined using the Medical Dictionary for Regulatory Activities preferred terms.

Methods: We analyzed reports of Reye's syndrome using the US Food and Drug Administration Adverse Event Reporting System and the Japanese Adverse Drug Event Report databases.
Hemorrhoids are a common anorectal disease. Epidemiological studies on medication trends and risk factors using information from real-world databases are rare. Our objective was to analyze the relationship between hemorrhoid treatment prescription trends and several risk factors using the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB) Open Data Japan and related medical information datasets.
