Naratriptan is a selective serotonin (5-HT₁B/1D) receptor agonist used for the acute treatment of migraine attacks with or without aura. It belongs to the triptan class of medications and works by causing vasoconstriction of cranial blood vessels and inhibiting the release of pro-inflammatory neuropeptides.
Naratriptan is typically administered orally and is known for its longer half-life compared to other triptans, offering sustained relief with a lower recurrence rate.
Indications include:
∙ Acute treatment of migraine headaches
∙ Relief from associated symptoms such as nausea, photophobia, and phonophobia

Impurities in naratriptan arise primarily from its multi-step chemical synthesis and degradation under environmental conditions. All impurities must meet ICH Q3A/B regulatory standards and pharmacopeial requirements (e.g., EP, USP) to ensure product safety and efficacy.

Naratriptan is used to treat migraine attacks in adults. It is not intended for migraine prevention or for treating other types of headaches.
It stimulates 5-HT₁B/1D receptors, causing vasoconstriction of dilated cranial blood vessels and blocking the release of neuropeptides involved in migraine pathophysiology.
It should only be used if clearly needed and prescribed by a healthcare provider. Safety data in pregnancy is limited.
Naratriptan has a slower onset but a longer duration of action, making it suitable for migraines with prolonged symptoms or recurrence.
