Whatever the mechanism responsible for the analgesic response seen in males, this research re-emphasizes the importance of psychological factors in determining drug response. We hypothesize that ibuprofen analgesia is produced by a combination of specific pharmacological effects and a non-specific beta endorphin-mediated placebo effect. Our study found that dosages of 800 mg of ibuprofen are ineffective in producing analgesia in women regardless of their expectations. The time course of analgesic action in males was as expected considering the pharmacokinetic profile of ibuprofen. When partitioned by sex and expectancy state, analgesia only occurred in males during positive expectancy states at 2, 3 and 4 h post-placebo, and at 1 and 2 h post-ibuprofen. We found no sex difference in baseline pain threshold or tolerance levels. We analysed the results using analysis of variance for repeated measures with baseline pain as a covariate. We randomly assigned subjects to start in one of the four expectancy states. Subjects took ibuprofen or placebo in a two-by-two factorial design (the balanced placebo design). We measured detection and tolerance thresholds for electrically induced pain in the ear lobe in healthy subjects (10 male, 10 female) to study sex differences in expectancy following either ibuprofen 800 mg or placebo in four different expectancy states. It’s one of the best ways to savor Miami’s unique ecosystem and natural beauty.To determine whether there is a sex difference in placebo and ibuprofen analgesia expectancy.
