Abstract

What Happens to the Old Headache Medicines?

Rapoport AM, MD

Old headache medicines never die; they either fade away or come back in disguise. The disguise is often a new route of administration, which may work better, faster, more completely, with fewer adverse events, and/or have certain other advantages. The clinical aspects of 3 of the oldest headache medicines (ergotamine tartrate, dihydroergotamine, and methysergide) will be discussed here. Sumatriptan will then be discussed as the prototype of the newest category of acute care therapy (triptans) for migraine. It will be compared with the older medications, and the new forms being developed will be briefly discussed. Diclofenac potassium for oral solution will be mentioned as the newest drug approved for migraine by the Food and Drug Administration and a possible alternative to triptans in patients with frequent headaches or those with contraindications to vasoconstrictors.

Dihydroergotamine, Ergotamine, Methysergide and Sumatriptan – Basic Science in Relation to Migraine Treatment

Dahlöf C, Maassen Van Den Brink A.

The 5-hydroxytryptamine (5-HT) receptor family mediates the effects of several drugs highly effective in migraine primarily by activating 5-HT1B, 5-HT1D, and 5-HT1F receptors. Ergotamine, dihydroergotamine and methysergide, as well as the “triptan” sumatriptan, are all agonists for these receptors. The receptor profile and degree of selectivity of these 4 drugs differ, which is reflected by their side effects that limit their use in the acute and prophylactic treatment of migraine. The acute antimigraine efficacy of these remedies is very much dependent on the formulation used where, in general, parenteral formulations are more effective in relieving the symptoms of a migraine attack.
