Why does sumatriptan prevent migraine attacks without reducing overall headache intensity?
OPEN
The study shows sumatriptan significantly reduces migraine attack incidence (15% vs 42%) but shows no difference in area under the curve for headache intensity. This dissociation between attack prevention and pain severity suggests distinct mechanisms that remain unexplained.
