Which of the following medications is also used for migraine prophylaxis?

Divalproex sodium is an anticonvulsant medication that is widely recognized for its effectiveness in the prevention of migraines. This medication works by stabilizing electrical activity in the brain and has been shown to reduce the frequency of migraine occurrences. Due to its mechanism of action and clinical studies supporting its use, it has become a standard choice for migraine prophylaxis in patients who experience frequent or debilitating migraines.

In contrast, pravastatin calcium is primarily used for managing cholesterol levels and reducing the risk of cardiovascular events, making it unsuitable as a migraine preventive. Tamsulosin hydrochloride is primarily used to treat benign prostatic hyperplasia (BPH) and facilitates urination but has no role in migraine management. Naproxen, although it can help relieve migraine symptoms once they occur due to its anti-inflammatory properties, is not typically used for long-term prevention of migraines. Thus, the unique application of divalproex sodium in migraine prophylaxis sets it apart from the other medications listed.
