Subtype-Dependent Reporting of Stroke With SGLT2 Inhibitors: Implications From a Japanese Pharmacovigilance Study.
Abstract Volume depletion as an adverse events (AE) caused by sodium-glucose cotransporter-2 inhibitors (SGLT2i) because of their diuretic effect may raise the concern about the risk of lacunar stroke; however, an earlier meta-analysis reported no significant increase in the incidence of stroke without clearly distinguishing stroke subtypes. Here, aiming to investigate subtype-wise reporting of stroke potentially related to SGLT2i treatment, we conducted a disproportionality analysis using the Japanese Adverse Drug Event Report database, which contains approximately 500 000 cases recorded between April 2004 and M...

Applications of Liposomal Drug Delivery Systems to Develop Neuroprotective Agents for the Treatment of Ischemic Stroke.
Abstract Ischemic stroke is one of the leading causes of severe disability and death. In clinical settings, tissue plasminogen activator (t-PA) for thrombolytic therapy is the only globally approved drug for the treatment of ischemic stroke. However, the proportion of patients who receive t-PA therapy is extremely limited due to its narrow therapeutic time window (TTW) and the risk of cerebral hemorrhage. Cerebral ischemia-reperfusion (I/R) injury is also a serious problem for patients' outcomes. Hence, the development of more effective therapies has been desired to prolong the TTW of t-PA and prevent cerebral I/R...

Examination of the Relationship between Worse Symptom and Differences Route during Administration of Argatroban in Acute Ischemic Stroke Patients.
Abstract The treatment of acute ischemic stroke usually involves argatroban administration by continuous infusion for 2 d and by intravenous infusion twice a day for 5 d after that. However, the appropriate dose of argatroban to be administered is not clear. Therefore, no studies have been reported a comparison of intravenous and continuous argatroban infusion after day 3 for acute ischemic stroke patients. We aimed to identify the connection between differences in argatroban administration and worsening of symptoms after day 3 in ischemic stroke patients. We retrospectively evaluated the data of 107 ischemic stro...

Cost-effectiveness Analysis of Apixaban against Warfarin for Stroke Prevention in Patients with Nonvalvular Atrial Fibrillation in Japan.
CONCLUSION: Although most participants in the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation (ARISTOTLE) trial used for the efficacy data of apixaban in the model were non-Japanese patients, the impact of the limitations on our results was considered small, and our results were deemed robust because of the additional effect in Japanese patients compared with that in the global population according to the subanalysis of Japanese patients in the trial. Therefore, based on an adaptation of a published Markov model, apixaban is a cost-effective alternative to warfarin in Japan for strok...

A noninferiority confirmatory trial of prasugrel versus clopidogrel in Japanese patients with non-cardioembolic stroke: rationale and study design for a randomized controlled trial - PRASTRO-I trial.
CONCLUSIONS: This article presents the study design and rationale for a trial investigating the noninferiority of prasugrel to clopidogrel sulfate with regards to the inhibitory effect on primary events in patients with non-cardioembolic stroke. PMID: 29463150 [PubMed - as supplied by publisher]

Reduction in the doses of direct oral anticoagulants and risk of ischemic stroke events: A hospital survey.
Abstract Inappropriately reduced doses (IRDs) of direct oral anticoagulants (DOACs) are common in clinical practice. We performed a retrospective review using electronic medical records of St. Marianna University School of Medicine Hospital (a 1200-bed teaching hospital in Japan) to address the prevalence of IRDs and patient-related factors that result in IRDs. We also surveyed DOAC-treated patients who were hospitalized due to a stroke during the 5-year study period to analyze the association between stroke events and IRDs. We found that one in five patients who were newly prescribed a DOAC was treated with IRDs....

Antithrombotic therapy for stroke prevention in patients with atrial fibrillation in Japan.
Authors: Maruhashi T, Higashi Y Abstract INTRODUCTION: Stroke remains one of the major public health problems in Japan. The number of patients with atrial fibrillation (AF) has been steadily increasing with the aging of the Japanese population. Appropriate oral antithrombotic therapy is necessary to prevent AF-related stroke and bleeding complications. AREAS COVERED: The authors summarize the Japanese guidelines for antithrombotic therapy, as well as the current status of antithrombotic therapy, and future perspectives for antithrombotic therapy for patients with AF in Japan. EXPERT OPINION: Further improve...

Development of Biomembrane-mimetic Nanoparticles for the Treatment of Ischemic Stroke
Yakugaku Zasshi. 2021;141(9):1071-1078. doi: 10.1248/yakushi.21-00114.ABSTRACTIncrease in vascular permeability of the blood-brain barrier (BBB) is a distinct pathology following ischemic stroke. In previous studies, we demonstrated that liposomal drug delivery system (DDS)-based delivery of neuroprotectants is useful for treating cerebral ischemia/reperfusion injury. Additionally, our previous studies reported that combination therapy with liposomal fasudil plus tissue plasminogen activator (t-PA), a thrombolytic agent, brings about decrease in the risk of t-PA-derived cerebral hemorrhage and prolong the therapeutic time ...
