Cytoprotective agents in stroke: Still uncertainty in the next frontier

Despite substantial improvement of acute ischemic stroke (AIS) care with the advent of extended time windows for intravenous thrombolysis (IVT) and endovascular thrombectomy (EVT), a substantial portion of patients still suffer poor outcomes. Additional adjuvant therapies are needed but pharmacologic interactions among therapies may dictate how they could be used. We conducted a survey to determine physician decision-making regarding the use of cytoprotective agents in patients presenting with AIS.

The survey was structured, web-based, anonymous, and invite-only among physicians across the world treating patients presenting with AIS. Respondents were asked about the use of a hypothetical cytoprotective agent (that provided an added 10% benefit) in the context of a treatment interaction with IVT or its timing in relation to IVT.

A total of 282 stroke physicians (74.9% males, mean age 46 years) participated in the survey. When the respondent could give both the cytoprotective agent and IVT with no treatment interaction, 177 (78.0%) chose to administer both. In the presence of treatment interaction, 88 (38.3%) would withhold IVT, 83 (36.1%) would withhold the cytoprotective agent and 56 (24.4%) were uncertain. Lastly, 111 (48.9%) were willing to administer the cytoprotective agent if it meant a necessary 10-minute delay in IVT administration.

Pharmacologic interactions result in major uncertainty about cytoprotective treatment choices.
