Zolmitriptan

Introduction: What is Zolmitriptan?

Zolmitriptan is a prescription medication used for the acute treatment of migraine attacks with or without aura in adults. It belongs to the triptan class of drugs and is not used to prevent migraines, but to treat them once they begin. Available as tablets, orally disintegrating tablets (ODT), and nasal spray, Zolmitriptan offers flexible options for quick relief.

Uses of Zolmitriptan

Zolmitriptan is used to relieve:

• Acute migraine headaches in adults (oral/ODT); nasal spray approved for adolescents (ages 12) and adults
• Migraine with aura (sensory disturbances before headache)
• Migraine without aura

Not indicated for cluster headaches or migraine prevention.

How Does Zolmitriptan Work?

Zolmitriptan is a serotonin (5HT1B/1D) receptor agonist. During a migraine, the blood vessels in the brain dilate, triggering inflammation and pain. Zolmitriptan works by:

• Constriction of enlarged brain blood vessels
• Blocking pain signals in the brainstem
• Inhibiting the release of inflammatory neuropeptides

This combined action provides rapid relief from migraine symptoms such as headache, nausea, sensitivity to light and sound, and aura-related visual disturbances.

Dosage and Administration

Oral Tablet or Orally Disintegrating Tablet (ODT)

• Adults only (?18 years)
• Initial dose: 2.5 mg at migraine onset
• Repeat dose (if needed): After at least 2 hours
• Maximum daily dose: 10 mg (usually not more than 2 doses per day)
• Hepatic impairment: Reduce to 1.25?2.5 mg (severe cases); use 2.5 mg max in moderate

Nasal Spray
