What condition is Nimodipine primarily prescribed for?

Nimodipine is primarily prescribed for the management of subarachnoid hemorrhage, particularly to improve outcomes following this condition. This medication is a calcium channel blocker that specifically helps in preventing vasospasm in the blood vessels around the brain after a subarachnoid hemorrhage. By relaxing these blood vessels, nimodipine promotes increased blood flow to the affected areas, reducing the risk of ischemic complications that can occur after the hemorrhage.

The other options do not align with the primary use of nimodipine. While nimodipine is a type of calcium channel blocker, its role in hypertension, angina, and chronic heart failure is not established to the same degree as its application for subarachnoid hemorrhage. The effectiveness of nimodipine for these other conditions is overshadowed by the specific benefits it provides in the context of treating and preventing complications from subarachnoid hemorrhage.
