Triptans work by tamping down overactive nerves in the brain caused by a migraine attack. They also help shrink blood vessels back to normal. This helps manage migraine symptoms. A 2015 research review compared triptans and other migraine treatment options.

The vasoconstrictive properties of triptans are mediated by an action on 5-HT1B in arterial smooth muscle.

Full Answer

What are the side effects of triptans?

In animal models and in humans, CGRP is elevated in the external jugular vein after stimulation of the trigeminal ganglion as well as during migraine attacks. Consistent with a peripheral action for triptans, treatment with sumatriptan reduces CGRP levels as the migraine subsides ( Goadsby and Edvinsson, 1993 ).

What are the different forms of triptans that treat migraines?

How does sumatriptan relieve migraines?

May 01, 2005 · Consistent with a peripheral action for triptans, treatment with sumatriptan reduces CGRP levels as the migraine subsides (Goadsby and Edvinsson, 1993). The localization of 5-HT 1D receptors on peptidergic nociceptors also points to a contribution of this receptor subtype in the reduction of peripheral activation by triptans ( Potrebic et al., 2003 ).

How do triptans act in migraines?

Triptan drugs work like a brain chemical called serotonin. This helps quiet down overactive pain nerves. In other words, triptans reverse the changes in your brain that caused your migraine.Feb 2, 2022

Where do triptans work?

Unlike other acute medications, triptans are considered selective serotonin receptor agonists, meaning that triptans work by stimulating serotonin, a neurotransmitter found in the brain, to reduce inflammation and constrict blood vessels, thereby stopping the headache or migraine.Nov 19, 2007

Which receptors do triptans work on?

Triptans are highly efficacious for the treatment of acute migraine headache. They act as serotonin 5HT 1B-, 1D-, and 1F-receptor agonists. These receptors are present in the umbilical artery and fetal brain.

What is the mode of action of triptans?

Mechanism of action. Their action is attributed to their agonist effects on serotonin 5-HT1B and 5-HT1D receptors in blood vessels (causing their constriction) and nerve endings in the brain, and subsequent inhibition of pro-inflammatory neuropeptide release, including CGRP and substance P.

When are triptans contraindicated?

Triptans are still the first choice therapy for acute migraine attacks. However, according to the terms of approval, triptans are contraindicated in uncontrolled arterial hypertension, coronary artery disease (CAD), and in patients after stroke or transient ischemic attack (TIA).Jan 22, 2020

Are triptans Vasoconstrictors?

Triptans work by vasoconstricting the meningeal blood vessels. It has been postulated that the higher rate of vascular events in these patients may be caused by use of these anti-migraine agents.Jun 15, 2002

Are triptans preventive or abortive?

Abortive treatments include the triptans and ditans, which specifically target serotonin. They are all very similar in their action and chemical structure. The triptans are used only to treat headache and do not relieve pain from back problems, arthritis, menstruation, or other conditions.Mar 9, 2022

How do triptans work on serotonin?

Unlike other acute medications, triptans are considered selective serotonin receptor agonists, meaning that triptans work by stimulating serotonin, a neurotransmitter found in the brain, to reduce inflammation and constrict blood vessels, thereby stopping the headache or migraine.Nov 19, 2007

Do triptans increase or decrease serotonin?

Triptans interact directly with some serotonin receptors in the brain. When these medications are taken together, they theoretically could cause much higher levels of serotonin and stimulation of serotonin receptors in your system than you'd experience if you were taking only one of these medications.

Are triptans serotonin agonists?

Triptans are used as abortive medications for moderately severe to severe migraine headaches. These drugs are selective serotonin agonists, specifically acting at 5-hydroxytryptamine 1B/1D (5-HT1B/1D) receptors on intracranial blood vessels and sensory nerve endings.Oct 1, 2021

When are triptans prescribed?

A triptan should be taken early during a migraine attack but not during the aura phase. Triptans are most effective if taken early in a migraine attack while the pain is still mild.

Do triptans work for all headaches?

Most people who have migraine can usually find a triptan that works well for most migraine attacks, and where side-effects do not occur or are not too bad. A main problem with triptans is that in about one in four cases, after taking a triptan which clears a headache, the headache returns within the next 48 hours.

Can triptans prevent migraines?

Triptans are one class, or group, of medications that can treat migraine attacks after they start. Triptans cannot prevent a migraine attack from happening. Instead, these medications help relieve symptoms by shrinking swollen blood vessels in the brain that develop from migraine attacks.

What receptors do triptans bind to?

Triptans bind to—or connect with—serotonin receptors. Specifically, triptans bind to subtypes of the receptor called 5-HT1B and 5-HT1D. Binding of the triptan to the 5-HT1B and 5-HT1D receptors in the brain reduces swelling in the blood vessels, which may be one reason they stop the migraine.
