Amphotericin B deoxycholate (AMPH-B) is a polyene macrolide with antifungal activity. Liposomal AMPH-B (L-AMB) was developed to reduce side effects while maintaining antifungal activity. This study was aimed at evaluating and comparing the adverse event profiles of AMPH-B and L-AMB using a spontaneous reporting system.

Background: Acute generalized eruptive pustulosis (AGEP) is a rare, but serious, drug-related adverse event. This study aimed to determine the relationships between AGEP and age, sex, primary disease, and prescription medications using a database of adverse drug events, namely, the Japanese Adverse Drug Event Report (JADER) database.

Methods: In this retrospective observational study, we analyzed AGEP reports extracted from the JADER database based on the preferred term for AGEP (code 10048799).

In this study, information on injectable anticancer drug use and additional fee for enhanced collaboration (AEC) and additional fee for specific drug management guidance 2 (ASD2) claims from the NDB Open Data Japan (NODJ) dataset and the number of patients with cancer according to sex and age from the National Cancer Registry (NCR) dataset were integrated and evaluated to determine the current status and challenges in pharmacist interventions for patients receiving cancer treatment. The NODJ data, including receipt data billed from 2020 to 2021, were obtained from the Ministry of Health, Labour and Welfare website. The use of injectable anticancer drugs decreased relative to the number of cancer patients aged ≥ 75 years compared to those aged < 75 years.

Adverse events (AEs) of antipsychotic drugs include neuroleptic malignant syndrome (NMS), which presents complex clinical symptoms, resulting in a fatal outcome. In this study, the association between antipsychotic drugs and NMS was comprehensively evaluated by cluster and association analyses using the Japanese Adverse Drug Event Report (JADER) database. The analyses were performed using 20 typical antipsychotics (TAPs) alongside 9 atypical antipsychotics (AAPs).
