Time interval of esomeprazole and dual antiplatelet therapy in patients with cardiocerebrovascular diseases.

Dual antiplatelet therapy (DAPT) with the combination of clopidogrel and aspirin is recommended for preventing secondary ischemic events in patients with acute coronary syndrome (ACS) or acute ischemic stroke (AIS). Proton pump inhibitors (PPIs) are suggested as preventive treatment for these patients. Due to clopidogrel-PPI interactions, separating their administration might be considered. However, a paucity of studies has been conducted to investigate the outcome differences between concurrent and interval-based use in ACS and AIS patients. Our study aimed to evaluate clinical outcomes based on administration timing. This study included patients with ACS or AIS onset or recurrence of within the last month. Patients who were expected to receive DAPT for at least 6 months and who were currently taking or planning to take esomeprazole were included. Patients were divided into Group 1 (interval administration group, IA group) and Group 2 (concurrent administration group, CA group) according to the interval between esomeprazole and DAPT administration. The time interval was based on 12 hours. The primary outcome was the occurrence of major adverse cardiocerebrovascular events (MACCEs), and safety outcomes were defined as major bleeding, minor bleeding and gastrointestinal bleeding and intracranial hemorrhage. A total of 3600 patients completed this study. The proportions of patients in the 2 groups were as follows: CA group, 99% (n = 3489) and IA group, 1% (n = 111). The primary outcome occurred in 0.9% of patients in the IA group and 1.8% of patients in the CA group (P = .51). There was no significant distinction in the overall bleeding risk of the CA group compared to that of the IA group (2.75% in the CA group and 2.70% in the IA group). Additionally, there was no significant difference observed between the 2 groups for safety outcomes. This multicenter, prospective, observational study that enrolled patients with ACS or AIS demonstrated that there was no significant difference in the occurrence of MACCEs and bleeding issues within 6 months according to the medication administration interval. The majority of patients with DAPT were taking PPIs simultaneously in real-world practice.

Safety and efficacy of tamsulosin 0.4 mg as an initial dose in 1,219 Korean patients with moderate to severe lower urinary tract symptoms: data from a phase IV study.

Background: An initial dose of tamsulosin 0.2 mg is frequently prescribed for Asian men. We investigated the safety and efficacy of tamsulosin 0.4 mg as the initial dose in Korean men with moderate to severe lower urinary tract symptoms (LUTSs) in everyday clinical practice. Materials and methods: A phase IV study was conducted in South Korea. Eligible patients were prescribed tamsulosin 0.4 mg for 6 months. We excluded patients with previous exposure to LUTS drugs and patients with an international prostate symptom score (IPSS) < 8. Results: The mean total IPSS, storage subscore, voiding symptoms subscore, and quality of life significantly decreased from 18.0, 10.8, 7.2, and 3.8 to 12.8, 7.5, 5.3, and 2.6, respectively, after 6 months of treatment. The number of nocturia episodes significantly decreased from 3.0 to 2.2 in patients who reported at least 2 nocturia events at baseline. A mean reduction in the IPSS was quantitatively equivalent in all age groups. The mean reduction in the IPSS was greater in the IPSS ≥ 20 group than in the IPSS < 20 group (mean reduction in the total IPSS: -2.6 in the IPSS < 20 group; -9.4 in the IPSS ≥ 20 group). All treatment-emergent adverse events were mild. The most frequently recorded treatment-emergent adverse event was dizziness, which was reported in 22 patients (1.8%). Conclusion: Treatment of LUTS with tamsulosin 0.4 mg as the initial dose for 6 months in Korean men was effective in improving LUTS and showed a favorable safety profile in a real-life setting.
