However, aminoglycosides are associated with significant risks of nephrotoxicity, necessitating careful dose selection and therapeutic drug monitoring. Therapeutic drug monitoring is essential for minimizing risk; however, few institutions routinely perform it.

Short-Term Efficacy and Safety of Suvorexant and Lemborexant: A Retrospective Study.

Purpose: Given the risks of long-term benzodiazepine use, safer alternatives like orexin receptor antagonists (ORAs) are needed for insomnia treatment. This study aims to compare suvorexant and lemborexant, focusing on early-stage sleep duration as an efficacy measure and fall incidence as a safety measure.

Methods: We included patients admitted to our hospital between April 1, 2022 and December 31, 2022, who were newly prescribed suvorexant or lemborexant, excluding patients taking other concomitant sleep medications or antipsychotics.

Identifying risk factors of dose reduction or treatment discontinuation due to fatigue or gastrointestinal symptoms in patients receiving lenvatinib treatment for hepatocellular carcinoma.

Introduction: Lenvatinib (LEN) is the standard treatment for hepatocellular carcinoma (HCC). In clinical practice, gastrointestinal (GI) symptoms such as fatigue and loss of appetite often lead to dose reduction or treatment discontinuation. This study aimed to identify the predictors of patients who will experience dose reduction or treatment discontinuation owing to fatigue or GI symptoms during LEN treatment for HCC.

Pharmacist-initiated interventions to test quantitative bone mineral density and prescribe osteoporosis medications to prevent steroid-induced osteoporosis.

Fragility fractures associated with glucocorticoid-induced osteoporosis (GIO) can markedly impair quality of life. However, only 20% of patients are treated in compliance with the relevant management guidelines, and bone mineral density analysis with dual-energy X-ray absorptiometry (DXA) is only rarely performed. We report the intervention methods suggested by pharmacists and describe their efficacy.

Safety evaluation of lenvatinib treatment after atezolizumab plus bevacizumab therapy for patients with unresectable liver cancer: A comparison of lenvatinib as 1st‑ or 2nd‑line treatment.

Atezolizumab plus bevacizumab (Atez/BV) as first-line therapy and lenvatinib (LEN) as second-line therapy are the recommended treatments for patients with unresectable hepatocellular carcinoma. Adverse immune events caused by immune checkpoint inhibitors (such as Atez) generally only occur several months after administration; therefore, the potential influence of the first-line treatment on second-line treatment is not clear. The present study investigated the safety of second-line LEN treatment (2nd LEN) by comparing the adverse events (AEs) of 2nd LEN after first-line Atez/BV treatment for unresectable liver cancer, with those of first-line LEN treatment (1st LEN).

Association between CDK4/6 inhibitors and drug-related osteonecrosis of the jaw: A pharmacoepidemiological study using the FDA Adverse Events Reporting System.

The most common toxicities associated with cyclin-dependent kinase (CDK) 4/6 inhibitor therapy include decreased leukopenia and neutropenia due to the inhibition of CDK6 of leukocyte and neutrophil precursors in bone marrow. These hematological toxicities are more commonly observed with palbociclib administration than with abemaciclib administration, which is approximately 13 times more selective against CDK4 than CDK6. Thus, even though both successfully inhibit CDK4/6, the side effects of palbociclib and abemaciclib differ due to differences in selectivity.

Vancomycin-Induced Neutropenia With Subsequent Perioperative Readministration: A Case Report.

Vancomycin (VCM), an essential antibiotic for antimicrobial-resistant Gram-positive cocci, can lead to complications such as neutropenia. Here, we present a case of a 25-year-old male with noncommunicating hydrocephalus due to an intraventricular tumor who developed neutropenia during VCM therapy. Despite the suspected VCM-induced neutropenia, short-term readministration was deemed necessary for perioperative infection prophylaxis.

Evaluation of Atezolizumab Plus Bevacizumab Modified Lenvatinib Therapy in Child-Pugh A Unresectable Hepatocellular Carcinoma.

Background/aim: Atezolizumab/bevacizumab (Atez/BV) and lenvatinib (LEN) are the recommended first-line treatments for patients with unresectable hepatocellular carcinoma (HCC). Previous reports have suggested that the tolerability and therapeutic efficacy of LEN could be enhanced by modifying its administration method. Therefore, this study compared the efficacy and safety of Atez/BV, the standard LEN therapy (standard LEN), and modified LEN therapy (modified LEN).

Pituitary-Related Adverse Events and Onset Patterns Caused by Immune Checkpoint Inhibitors: Analysis Using the Japanese Adverse Drug Event Report Database.

: One type of immune-related adverse event caused by immune checkpoint inhibitors (ICIs) is pituitary-related adverse events. The management of pituitary-related adverse events is important because they can be fatal if not treated promptly. Therefore, this study was conducted to investigate the onset of pituitary-related adverse events using the Japanese Adverse Drug Report (JADER) database.

Evaluation of the therapeutic effects and tolerability of modified lenvatinib administration methods for unresectable hepatocellular carcinoma: A preliminary study.

Lenvatinib (LEN), a multitarget tyrosine kinase inhibitor, is a standard therapeutic agent for hepatocellular carcinoma, but the high incidence of adverse events (AEs) related to LEN treatment often necessitates treatment discontinuation. The present study aimed to clarify the therapeutic efficacy and tolerability of modified LEN dosing methods, such as alternate-day dosing, necessitated by AEs of LEN. A total of 66 patients who received LEN at Ogaki Municipal Hospital (Ogaki, Japan) between April 2018 and January 2022 were retrospectively evaluated.

Analysis of adverse events leading to dose reduction/interruption of lenvatinib treatment in patients with Child-Pugh B unresectable hepatocellular carcinoma.

Introduction: We aimed to compare the safety of lenvatinib as first-line treatment for unresectable hepatocellular carcinoma (HCC) in patients with Child-Pugh A (CP-A) and Child-Pugh B (CP-B) and to determine the adverse events (AEs) that cause dose reduction/interruption of treatment in patients with CP-B.

Methods: Sixty-six patients with lenvatinib as a first-line treatment for HCC at Ogaki Municipal Hospital (Ogaki, Japan) between April 2018 and January 2022 were retrospectively evaluated. We analyzed the treatment duration, AEs, and reasons for dose reduction/interruption associated with lenvatinib treatment in patients with CP-A and CP-B HCC.

In this study, we evaluated the safety of bevacizumab plus FOLFIRI with that of ramucirumab plus FOLFIRI in second- and later-line treatment in Japanese patients with metastatic colorectal carcinoma. Patients who received ramucirumab or bevacizumab as a second- and later-line treatment between January 2016 and March 2020 were included.

Expression of Vincristin-induced Peripheral Neuropathy Related to Different Administration Methods.

Vincristine (VCR) is an important drug used in R-CHOP regimens for the treatment of non-Hodgkin's lymphoma. The purpose of this study was to examine whether the administration method affects the incidence of VCR-induced peripheral neuropathy. We investigated the ratio of VCR-induced peripheral neuropathy during rapid intravenous infusion and intravenous drip infusion.

Elucidation of optimal proteinuria management based on the risk of ramucirumab-induced proteinuria.

Proteinuria is a dose-limiting adverse effect of ramucirumab treatment, which is an anti-angiogenic agent that targets the human vascular endothelial growth factor. The predictors of proteinuria have not been completely elucidated and there is currently no consensus. The present study aimed to identify the risk factors for ramucirumab-induced proteinuria and to determine an optimal proteinuria management.

Identifying prognostic factors associated with overall survival in second-line paclitaxel plus ramucirumab treated human epidermal growth factor receptor 2-negative advanced/recurrent gastric cancer.

This study aimed to identify the overall survival prolongation index in patients who received paclitaxel plus ramucirumab as second line chemotherapy for human epidermal growth factor receptor (HER) 2-negative advanced/ recurrent gastric cancer (AGC). We included 77 patients who underwent second line chemotherapy (paclitaxel plus ramucirumab) for AGC at our institution between January 2015 and September 2020. To determine factors associated with survival, univariate and multivariate analyses were performed, and hazard ratios and their 95% confidence intervals (95% CI) were calculated.
