I originally posted this over on the Med board, but thought I would post here too so it got maximum exposure:

Sumatriptan 4 mg Statdose in the Acute Treatment of Cluster Headache

GSK is recruiting patients through the diamond headache clinic for the 4 mg statdose specifically designed for CH sufferers.

Study information can be obtained from clinicaltrials.gov at this website:

While I'm not a proponent of triptans for CH because of the many anecdotal cases of evidence showing many negatives, the best chance for CHers to get new drugs out such as the CGRP receptor antagonists, is if we as sufferers can get our numbers out there to the researchers and the pharmco's;  one way is to make sure whatever studies they are doing, get filled.

Just a heads up for anyone who's interested.
