MIGRAINE HEADACHE AGENTS

OVERVIEW
Migraine Headache Agents

 

Migraine headaches are marked by repeated, paroxysmal attacks of moderate-to-severe throbbing, one-sided headaches which (without treatment) last 4 to 72 hours and are usually associated with symptoms of nausea and vomiting.  Migraine headaches are typically exacerbated by motion, bright lights and loud noises.  Migraines may be associated with focal neurological symptoms referred to as “aura” which are typically visual, but may be sensory or motor.  Migraine headaches are common, affecting at least 18% of women and 6.5% of men in the United States.  The pattern of paroxysmal headaches typically arises in adolescence or young adulthood and may be life-long.  The headaches often interfere with daily activities and can be incapacitating, result in major time loss from work and precipitate multiple physician and emergency room visits.  Patients with migraine may also be at increased risk for other vascular complications such as stroke and eclampsia.

The cause of migraine headaches is not fully understood, but appears to be related to arteriolar vasodilation and inflammation of the trigeminal nerve endings, perhaps caused by local release of vasoactive peptides.

 

Therapy of migraine headache usually combines preventive treatments with early intervention for acute attacks.  A great number of medications are used for migraine headaches including nonsteroidal antiinflammatory agents, opiate and nonopiate analgesics, barbiturates, antiemetics, ergot alkaloids, and serotonin receptor agonists.  Medications used specifically for migraine headaches and discussed here are the ergot alkaloids and the more recently developed serotonin receptor agonists (triptans).  The ergot alkaloids have been in use for many years, and currently available forms include ergotamine (Cafergot: year of approval, 1948) and dihydroergotamine (Migranal: 1946).  The triptans include sumatriptan (Imitrex: 1997), zolmitriptan (Zomig: 1997), naratriptan (Amerge: 1998), rizatriptan (Maxalt: 1998), almotriptan (Almogran, Axert: 2001), frovatriptan (Frova: 2001), and eletriptan (Relpax: 2002).


The ergot alkaloids and triptans rarely cause liver injury, perhaps because they are used for a short time only and in low doses.  Rare instances of clinically apparent liver injury have been described in patients taking zolmitripan and rizatriptan.  General references on the safety and hepatotoxicity of the drugs used specifically for migraine are provided with this introductory section.  The specific agents are discussed after each overview section [ergot alkaloids and triptans] and a more complete set of references are given regarding their safety and postential for hepatotoxicity.
