Prothrombin complex concentrate administration timing in warfarin-associated intracranial hemorrhage.

Introduction: Guidelines recommend "rapid" and "urgent" reversal of anticoagulation for warfarin-associated intracranial hemorrhage (ICH) treatment; however, they do not specify goals for time-to-administration. There are limited studies evaluating time to reversal, or international normalized ratio (INR) correction, on hematoma expansion and outcomes in intervals of <4 h. The purpose of this study was to evaluate the association of 4-factor prothrombin concentrate (4F-PCC) time-to-administration on rates of achieving effective hemostasis, determined by hematoma expansion, for treatment of warfarin-associated ICH.

A Case of Ivermectin-Induced Warfarin Toxicity: First Published Report.

Here, we present the case of a patient who developed a large hematoma under his tongue while taking concomitant warfarin and ivermectin. Ivermectin has been shown to interfere with vitamin K-dependent clotting factors II, V, VII, and X. However, all the data to date have been from in vivo data with little to no reports on its effects on humans.

Pharmacoeconomic impact of an alternative workflow process for stroke.

Objective: The objective of this study was to evaluate a new multidisciplinary process in which intravenous alteplase (tPA) waste, used for acute ischemic stroke (AIS), was salvaged in an attempt to maximize cost effectiveness without impacting door-to-needle (DTN) administration times.

Design: This was a retrospective cohort between May 2017 and February 2018. The primary endpoint evaluated for this study was the total tPA salvaged and total cost savings in U.
