A Multi-center, Randomized, Double-blind, Parallel-group Single-dose, Placebo-controlled Study Comparing the Efficacy and Safety of Acetaminophen, Aspirin and Caffeine With Sumatriptan in the Acute Treatment of Migraine.

The main purpose of this study is to compare the efficacy and safety of aspirin, acetaminophen and caffeine (AAC) with sumatriptan and placebo in the acute treatment of migraine.

Inclusion criteria:

1. Male or female aged 18 years and over.

4. History of at least moderate migraine pain intensity, if left untreated.
