The non-hallucinogen 2-bromo-lysergic acid diethylamide as preventative treatment for cluster headache: An open, non-randomized case series

This open-label, case series study (n=6) investigated the efficacy of the non-hallucinogenic LSD-analog BOL-148 (3 doses of 2100µg/70kg) for treating cluster headaches within a clinically diagnosed patient sample. The results show that three single doses of BOL-148 within 10 days can either break a cluster headache cycle or considerably improve the frequency and intensity of attacks, even resulting in changing from a chronic to an episodic form, with remission extending for many months or longer.

Abstract

From the introduction:

“Cluster headache (CH) is a stereotyped primary headache characterized by strictly unilateral severe orbital or periorbital pain and categorized as either episodic or chronic. Its prevalence is 0.1%. Oxygen and sumatriptan are the treatments of choice for individual attacks, whereas verapamil, lithium, corticosteroids and other neuromodulators can suppress attacks during cluster periods. All standard medication treatments may be ineffective. Surgical treatment may be an option for medication non-responders, including deep brain or occipital nerve stimulation. However, serious complications from brain surgery, including death, can occur…”
