Abstract
Novel pharmaceutical agents are under evaluation for improving stroke treatment and prevention.
- Tenecteplase may serve as an alternative thrombolytic drug to alteplase.
- Nerinetide is considered a promising neuroprotective agent for stroke patients.
- Glibenclamide could reduce edema in malignant hemispheric infarction.
- Ticagrelor and factor XI inhibitors are being explored for use in the subacute phase after stroke.
- Combined rivaroxaban and antiplatelet therapy may enhance treatment outcomes.
- Non-statin hypolipidemic agents and novel antidiabetic drugs have shown potential in reducing long-term cardiovascular events.

INTRODUCTION: Recent years have witnessed unprecedented progress in stroke care, but unmet needs persist regarding the efficacy of acute treatment and secondary prevention. Novel approaches are being tested to enhance the efficacy of thrombolysis or provide neuroprotection in non-thrombolized patients.
AREAS COVERED: The current review highlights pharmaceutical agents under evaluation in clinical trials concerning the acute, subacute, and chronic phase post-stroke. We examine the evidence in favor of tenecteplase as an alternative thrombolytic drug to alteplase, nerinetide as a promising neuroprotective agent, and glibenclamide for reducing edema in malignant hemispheric infarction. We discuss the use of ticagrelor and the promising novel category of factor XI inhibitors in the subacute phase after stroke. We offer our insights on combined rivaroxaban and antiplatelet therapy, PCSK-9 inhibitors, and other non-statin hypolipidemic agents, as well as novel antidiabetic agents that have been shown to reduce cardiovascular events in the long-term.
EXPERT OPINION: Current approaches in stroke treatment and stroke prevention have already transformed stroke care from a linear one-for-all treatment paradigm to a more individualized approach that targets specific patient subgroups with novel pharmaceutical agents. This tendency enriches the therapeutic armamentarium with novel agents developed for specific stroke subgroups.
