Antimigraine

Drug Axert for Migraine

During a migraine headache attack, changes in brain activity induce inflammation of blood vessels and nerves in the head. Attacks may be triggered by alcohol, certain foods, too much or too little sleep, menstruation, emotional stress, or environmental factors.

Eletriptan Hydrobromide

Eletriptan should not be used in patients with severe hepatic or severe renal impairment. Blood pressure effects of eletriptan are increased in renal impairment and therefore the dose should be reduced in patients with mild to moderate renal impairment. No dosage adjustment is needed in mild or moderate hepatic impairment.

Methysergide

Slightly soluble in water and in methyl alcohol; practically insoluble in chloroform and in ether. A 0.2% solution in water has a pH of 3.7 to 4.7. Store at a temperature of 2° to 8°.

Antimigraine Drugs

This post reviews the management of headache, in particular migraine and cluster headache, and the drugs used mainly for their treatment. The mechanisms of head pain or headache are not fully understood but may involve neurovascular changes (as in migraine and cluster headache), muscle contraction (tension headache), nerve lesions (neuralgias), direct head injury, infection (meningitis), or referred pain (sinusitis, toothache, eye disorders).

Almotriptan Malate

Almotriptan should not be used in patients with severe hepatic impairment since clearance is likely to be markedly impaired, and should be given with caution, and in reduced doses, to patients with mild to moderate hepatic impairment. The dose of almotriptan should also be reduced in patients with severe renal impairment.

Frovatriptan

Frovatriptan should not be used in patients with severe hepatic impairment. No dosage adjustment is needed in mild or moderate hepatic impairment. After oral doses, peak plasma-frovatriptan concentrations are attained in 2 to 4 hours, and bioavailability is about 20% in men and 30% in women.

Rizatriptan Benzoate

Toxic epidermal necrolysis has also been reported with rizatriptan. Rizatriptan should not be used in patients with severe hepatic or renal impairment and should be given with caution to patients with mild or moderate hepatic or renal impairment. After oral doses, peak plasma-rizatriptan concentrations are obtained in about 1 to 1.5 hours or 1.6 to 2.5 hours depending on the formulation.

Pizotifen

Pizotifen is a medication that belongs to the class of drugs known as tricyclic antidepressants. However, it is more commonly used for its antiserotonergic and antihistaminic properties rather than its antidepressant effects. It is primarily prescribed for the prevention of migraines and other vascular headaches.

Zolmitriptan

Zolmitriptan should also be avoided in patients with Wolff-Parkinson-White syndrome or arrhythmias associated with accessory cardiac conduction pathways. It should be given with caution in patients with moderate to severe hepatic impairment.

Ergotamine Tartrate

Ergotamine is commonly used as the tartrate. It is usually given orally but has also been given sublingually, rectally, and by oral inhalation. It was formerly given by subcutaneous or intramuscular injection.

Sumatriptan

A white to pale yellow powder. Very slightly soluble in water. A white to pale yellow powder.

Naratriptan Hydrochloride

Store in airtight containers at a temperature not exceeding 30°. Naratriptan should not be used in patients with severe hepatic or renal impairment (creatinine clearance less than 15 mL/minute) and should be used with caution in mild or moderate renal or hepatic impairment.

Dihydroergotamine

Dihydroergotamine (DHE) is a medication used to treat migraines and cluster headaches. It belongs to a class of drugs called ergot alkaloids, which have vasoconstrictive properties. DHE works by narrowing the blood vessels in the brain, which can help alleviate the throbbing pain associated with migraines.
