Treatment of choice of acute migraine is –
**Core Concept**
The treatment of acute migraine involves the use of specific medications that target the pathophysiology of the condition, including vasodilation, pain modulation, and inflammation. The goal is to alleviate symptoms and prevent further complications.
**Why the Correct Answer is Right**
Sumatriptan, a selective 5-HT1B/1D receptor agonist, is the treatment of choice for acute migraine due to its ability to cause vasoconstriction of intracranial blood vessels and inhibit pro-inflammatory neuropeptide release. This results in the alleviation of migraine symptoms, including headache, nausea, and vomiting. Sumatriptan's mechanism of action is primarily through its binding to 5-HT1B and 5-HT1D receptors on the terminal ends of the trigeminal nerve, which leads to the reduction of pro-inflammatory neuropeptide release and subsequent vasoconstriction.
**Why Each Wrong Option is Incorrect**
**Option A:** Ergotamines, such as ergotamine tartrate, are older medications used to treat migraines but are not the first-line treatment due to their side effects and lower efficacy compared to sumatriptan.
**Option B:** Corticosteroids are used in the treatment of migraine but are not the primary treatment for acute migraine attacks. They are more commonly used in the setting of status migrainosus or to prevent migraine recurrence.
**Option C:** Triptans are a class of medications that include sumatriptan, but not all triptans are created equal. Rizatriptan and zolmitriptan are other examples of triptans that are used to treat migraines, but sumatriptan is the most commonly used and effective medication.
**Clinical Pearl / High-Yield Fact**
The 5-HT1B/1D receptor agonists, such as sumatriptan, are a class of medications that are highly effective in the treatment of acute migraines. However, they are contraindicated in patients with a history of ischemic heart disease, as they can cause vasoconstriction and potentially worsen cardiac symptoms.
**Correct Answer: C. Sumatriptan**
