Abstract
Recurrence was first recognised as a clinical problem in 1989 with the advent of sumatriptan. The history of recurrence in early sumatriptan randomised clinical trials is described. Recurrence has been ascribed to patient-dependent factors but experience with ergot alkaloids suggested that recurrence can also be treatment-dependent. Possible mechanisms for recurrence are discussed.Entities:
