Final answer:
The correct answer for terminating an acute migraine attack is Triptans. They are designed to target migraine symptoms via serotonin receptor agonism. NSAIDs can also provide relief but are not as specialized for migraines as Triptans.
Step-by-step explanation:
The subject matter involves the treatment of migraine attacks and considerations for first-line medications. When discussing first-line drugs for terminating an acute migraine attack, the correct answer is Triptans. These drugs are specifically designed to combat the symptoms of migraines through their agonist effects on serotonin receptors. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin, ibuprofen, and naproxen, are also utilized for migraine relief and are widely available over the counter. However, they are more general in their action and are not as targeted as Triptans for migraines. Beta-blockers and Anticonvulsants, while important for migraine prevention, are not considered first-line treatments for the active termination of a migraine attack. In the context of anaphylactic shock, the immediate first-line treatment is Epinephrine, not addressed in this particular question but relevant in emergency cases of severe allergic reactions.
