I. Introduction

Sumatriptan, a prescription medication commonly used to address migraines and cluster headaches, is a serotonin receptor agonist. It works by impacting substances in the brain and narrowing blood vessels around the brain, providing relief from the throbbing or pulsating pain associated with these types of headaches. The development of Sumatriptan took place in the 1980s marking a significant advancement in our understanding and management of severe headaches such as migraines and cluster headaches. Following evaluation, Sumatriptan gained FDA approval in 1991. While initially approved for treating migraines, its indications were expanded to include cluster headaches.

II. Uses of Sumatriptan

Sumatriptan is commonly used to treat migraines and cluster headaches, effectively reducing the intense pulsating pain experienced during migraines. It is also recommended to alleviate the sharp, piercing pain accompanying cluster headaches. Sumatriptan works in treating headaches by stimulating serotonin (5 HT1) receptors in the brain123This stimulation causes the muscles surrounding the blood vessels in the brain to contract, resulting in a narrowing of these vessels124Consequently, this helps relieve headache pain by reducing blood flow24 and blocking the release of certain natural substances that cause pain, nausea, and other symptoms of migraine2.
