Randomized Controlled Trial Multicenter Study Clinical TrialIbuprofen plus caffeine in the treatment of tension-type headache.
The effectiveness of caffeine as an adjuvant to ibuprofen has been documented in investigations of acute pain. Our objectives were to assess this agent in the treatment of tension-type headache and to establish clinical trial methods capable of assessing this agent in comparison with various tension headache treatments. Stopwatch technology was used for measurement techniques. ⋯ Sensitive methods have been introduced to assess differences in analgesia among over-the-counter analgesic agents in relieving tension-type headache pain. A double-blind study with this method suggests that ibuprofen and caffeine administered together provides greater analgesic effectiveness than either component alone.
