Relationship of Reduced Pain Intensity and Improved Quality-of-Life with Menstrual Migraine with Aspirin, Acetaminophen, and Caffeine Combination.

The objective of the current post hoc analysis is to evaluate whether the combination of acetaminophen, aspirin, and caffeine (AAC) is more effective than placebo in relieving the pain intensity for and improving the quality-of-life (QoL) of subjects with menstrual migraine (MM). This analysis evaluated the impact of AAC (n = 85) versus placebo (n = 100) in relieving the pain intensity for and improving the QoL of subjects with MM during baseline and at 0.5, 1, 2, 3, 4, and 6 h post treatment. Subjects reported their pain intensity using a 4-point scale and QoL using a 5-point scale. A lower score indicates reduced pain intensity and improved QoL. A statistically significant difference between the AAC and placebo groups ( ≤ 0.001) was observed in pain relief after 1 h (40% vs. 14%), 2 h (56.5% vs. 24%), 3 h (63.5% vs. 31%), 4 h (65.9% vs. 34%), and 6 h (64.7% vs. 31%) post treatment. Similarly, a significantly higher proportion of subjects reported improved QoL at 1 h (48.2% vs. 28.0%; ≤ 0.005), 2 h (61.2% vs. 40.0%; ≤ 0.005), 3 h (68.2% vs. 44.0%; ≤ 0.001), 4 h (67.9% vs. 39.0%; ≤ 0.001), and 6 h (64.3% vs. 37.0%; ≤ 0.001) post treatment. The mean pain intensity and QoL scores reduced, while the relative pain intensity and QoL (difference between the AAC and placebo groups) increased with time and was sustained for 6 h. The rapid onset and sustained effect of AAC make it a potential option for managing headaches and other symptoms, and to improve the QoL of subjects with MM.
