A evaluation of the effect of verapamil and other calcium channel blockers in cluster headache (CH) treatment and an investigation of possible effect mechanisms. 
Efficacy of galcanezumab in patients with episodic cluster headaches and a history of preventive treatment failure
TLDR
The efficacy of galcanezumab was evaluated in patients with episodic cluster headache and history of preventive treatment failure in a randomized, 8-week, double-blind study. Expand
Episodic and Chronic Cluster Headache: Differences in Family History, Traumatic Head Injury, and Chronorisk
TLDR
The diagnostic criteria of episodic and chronic cluster headache were recently modified, yet pathophysiological differences between the two are still unclear, and other differences between episodi and cCH are identified and characterized. Expand
Cluster headache therapies: pharmacology and mode of action
TLDR
This article reviews acute and preventive substances for the pharmacological treatment of CH with a focus on the mode of action of these drugs, and suggests future studies with CGRP(R) antibodies and novel substances with specific actions are needed to understanding the pathophysiology of CH. Expand
Peptides, MAbs, Molecules, Mechanisms, and More: Taking a Stab at Cluster Headache.
TLDR
Recent therapeutic advances in the treatment of cluster headache such as monoclonal antibodies as well as non-invasive vagus nerve stimulation are highlighted, and future potential therapeutic targets are examined. Expand
Recently available and emerging therapeutic strategies for the acute and prophylactic management of cluster headache: a systematic review and expert opinion
TLDR
A deeper insight into CH pathophysiology, and combined approaches may lead the path to new, more effective, and personalized CH therapies. Expand
Cluster Headache and Other Trigeminal Autonomic Cephalalgias
TLDR
TAC syndromes are rare but important to recognize because of their debilitating nature and greater likelihood for having potentially serious underlying causes and how best to manage them. Expand
Recent Advances in the Management of Cluster Headache
TLDR
A deepening of the understanding of cluster headache mechanisms in recent years has driven the evolution of sophisticated therapeutic approaches that could allow a new era in the treatment of this difficult condition. Expand
Pharmacotherapy for Cluster Headache
TLDR
A new addition to the preventive treatment options in episodic cluster headache is galcanezumab, although the long-term effects remain unknown. Expand
Drug profile: galcanezumab for prevention of cluster headache
TLDR
The negative trial results of galcanezumab for chronic cluster headache may be due to the refractory nature and sheds light on the critical need to investigate the underlying biology and therapeutic options. Expand
Real-life treatment of cluster headache in a tertiary headache center – results from the Danish Cluster Headache Survey
TLDR
Episodic cluster headache is more responsive to acute therapy than chronic and sumatriptan injection was more effective than oxygen and the responder-rate was limited with verapamil. Expand

TLDR
Although available studies seem to demonstrate an apparent good tolerance, this off-label practice should not be considered as standard of care and requires strict cardiac monitoring, as suggested by the Agence Nationale de Sécurité du Médicament (ANSM) in a recent re-evaluation of the benefit/risk ratio of high-dose verapamil used in CH prevention.
