Arrow-Sumatriptan tablets 100mg are specific for treatment of migraine attack to relieve headache and other symptoms, including nausea and sensitivity to light, but they are not used to prevent migraine headaches. You can use Arrow-Sumatriptan 100 at any stage of a migraine attack but it is more effective if taken as soon as possible after the first signs of headache and/or aura. Arrow-Sumatriptan 100 is not effective for treatment of other types of headache.
How does Sumatriptan work?
Arrow-Sumatriptan tablets 100mg contain sumatriptan, which is a member of the group of drugs called triptans and is a serotonin agonist that mimics the action of serotonin (also known as 5-hydroxytryptamine, or 5-HT). Serotonin is a brain chemical that is involved in control of mood, pain sensation, sexual behaviour and sleep; as well as constriction (narrowing) of blood vessels. Migraine is thought to be caused by dilatation or widening of blood vessels in the head due to one of many migraine triggers, which in turn stimulates nearby sensory nerves so that you feel pain. Sumatriptan in Arrow-Sumatriptan 100 stimulates the serotonin receptors in these expanded blood vessels making them narrow again (vasoconstriction) and inhibits trigeminal nerve activity, relieving pain. Both actions are thought to contribute to the anti-migraine action of sumatriptan and relieve headache and other symptoms of a migraine attack.
What does Arrow-Sumatriptan contain?
Arrow-Sumatriptan tablets 100mg contain the active ingredient sumatriptan succinate, which is a serotonin agonist used to relieve symptoms of a migraine attack. They also contain microcrystalline cellulose, croscarmellose sodium, magnesium stearate and anhydrous lactose.
