Calcitonin gene-related peptide (CGRP) is a validated target for the treatment of episodic migraine. Here we assess the safety, tolerability, and efficacy of TEV-48125, a monoclonal anti-CGRP antibody, in the preventive treatment of high-frequency episodic migraine.Read More →
Cluster headaches (CHs) are one of the most debilitating of all the identified headache syndromes. Their pathogenesis is poorly understood, which has made their treatment challenging. Various medicines and modalities have been put forth in an effort to minimize the symptoms, but none have proven to be consistently reliable. Read More →
Since its discovery, Onabotulinum toxins have been tried for the treatment of various head, neck and face pain syndromes. The end result of controlled clinical trials was that there was not clear evidence for use in many of the common primary and secondary headaches. In chronic migraine, affecting 1-2% of the population, a fixed site and fixed dose treatment approach was shown to be superior to placebo and was approved for use. In this review, evidence for that use and the history leading to it is described.Read More →
Cluster headache (CH) is a primary headache disorder with relatively effective treatments. Although few sufficiently controlled trials are available, verapamil is recommended as the first-line prophylactic drug for CH by the French Headache Society (with a low level of evidence, level B) and by the EFNS (European Federation of Neurological Societies, level A). Daily doses of more than 480 mg (and up to 1200 mg daily) are frequently used off-label, while 360 mg daily is the only dosage to have demonstrated its effectiveness in a double-blind trial against placebo, and the usual label posology used by cardiologists is 240 mg daily in hypertension.

Hallucinogens are as old as civilization. Many cultures recorded eating certain plants specifically to induce visions or alter the perception of reality. Often these hallucinations were part of a religious or prophetic experience. Shamans in Siberia were known to eat the hallucinogenic mushroom Amanita muscaria . The ancient Greeks and the Vikings also used naturally occurring plant hallucinogens. Peyote, a spineless cactus native to the southwestern United States and Mexico was used by native peoples, including the Aztecs, to produce visions.Read More →
Migraine is a highly prevalent headache disease that typically affects patients during their most productive years. Despite significant progress in understanding the underlying pathophysiology of this disorder, its treatment so far continues to depend on drugs that, in their majority, were not specifically designed for this purpose. The neuropeptide calcitonin gene-related peptide (CGRP) has been indicated as playing a critical role in the central and peripheral pathways leading to a migraine attack.Read More →
This article highlights the evidence behind the role of CGRP in migraine and the state of CGRP-based mechanism treatment development. We present a summary of the evidence base behind CGRP in migraine pathophysiology and the novel CGRP mechanism drugs and their potential future contribution to migraine management in our clinical practice.Read More →
