Sumatriptan is used for the treatment of which conditions?

Explanation:
Sumatriptan works by activating 5-HT1B/1D receptors, which constricts cranial blood vessels and dampens the release of pain-mediating substances in the trigeminal system. This makes it effective for aborting acute migraine attacks, and it also helps with acute cluster headaches that involve a similar trigeminal-vascular mechanism. Tension-type headaches, on the other hand, are not driven by the same vasodilatory and trigeminal pathways, so sumatriptan is not a standard or effective treatment for them. Therefore, the best choice covers both migraine and cluster headaches.
