Nimodipine in Aneurysmal Subarachnoid Hemorrhage: Are Old Data Enough to Justify Its Current Treatment Regimen?

Nimodipine, a dihydropyridine L-type calcium channel antagonist, constitutes one of the mainstays of care to prevent delayed cerebral ischemia in patients with aneurysmal subarachnoid hemorrhage (aSAH) because it has been associated with a reduction in infarction rates and improvement in functional outcomes despite not significantly preventing angiographic vasospasm. Although it is a widely accepted treatment, controversies surrounding the current regimen of nimodipine in patients with aSAH exist. Still, there is a wide space open for randomized controlled trials or alternative study designs comparing different routes of administration, dosing, and timing of nimodipine treatment regimen in patients with aSAH.
