Thromboxane Synthetase Inhibition: Potential Therapy in Migraine

Authors


Abstract

SYNOPSIS

Sixteen patients with migraine were treated prophylactically for 3 months with dazoxiben, a specific thromboxane synthetase inhibitor, in an open study, Frequency of all attacks was reduced by more than 50% in 7 patients, and of severe attacks in 8 of 10 patients who initially suffered severe attacks. Reductions in thromboxane B2 levels measured at intervals during treatment by radioimmunoassay may have reflected standards of compliance with the 6-hourly treatment regimen. However, a relationship emerged between thromboxane reduction and clinical response, with significantly greater reductions observed in patients who reported good symptomatic relief. This appears to support the hypothesis that platelet activation features in migraine causation.
