Nimodipine IV is primarily used to prevent cerebral vasospasm following a subarachnoid hemorrhage (SAH). This means it helps keep blood vessels in the brain from narrowing dangerously after a bleed in the space surrounding the brain. The drug works by relaxing these blood vessels, improving blood flow.
Specific Use Cases
Clinicians prescribe Nimodipine IV for patients at high risk of developing delayed cerebral ischemia after SAH. This is a serious complication that can lead to significant neurological deficits or death. Prompt administration is crucial for optimal effect. While it’s effective in preventing vasospasm, Nimodipine IV doesn’t treat the initial bleeding itself.
Important Considerations
Nimodipine IV administration requires careful monitoring of blood pressure and heart rate. It’s frequently given through a continuous intravenous infusion. Healthcare professionals should closely observe patients for side effects like hypotension (low blood pressure), tachycardia (rapid heart rate), and headaches. Dosage adjustments are common, tailored to individual patient response and tolerance.
