Which medication is commonly used as premedication for neuro angiography?

The use of clopidogrel as premedication for neuroangiography is based on its role as an antiplatelet agent. During neuroangiography procedures, there is a risk of thromboembolic complications, particularly in patients with atherosclerotic vascular disease. Clopidogrel helps prevent the formation of blood clots by inhibiting platelet aggregation, thereby reducing the risk of stroke or other complications during the procedure.

Premedicating with clopidogrel can enhance patient safety by ensuring that the blood remains less likely to form clots, particularly when manipulating the vasculature or introducing contrast media into blood vessels. Its effectiveness and safety profile make it a common choice in the pre-procedural setting for neuroangiography.

In contrast, warfarin is an anticoagulant that would typically be managed very carefully and often held or adjusted prior to procedures, while atorvastatin is primarily used for cholesterol management, and metformin is used for managing diabetes, neither of which directly contribute to the prevention of thromboembolic events in the context of neuroangiography.
