Abstract：
PURPOSE:To determine whether two of the major operational stressors associated with military missions in Afghanistan: dry heat and long durations of soldier patrol (SP), alter the pharmacokinetics of ibuprofen. METHODS:Thirteen healthy and physically fit participants (19-32 years) were randomized to a four-arm crossover study, as follows: Arm 4 consisted of a simulated 2.5 h SP on a treadmill set at 4.5 km/h, 2% incline (15-min walk/5-min rest cycle) in a climatic chamber set to 42°C, 9% relative humidity. Arm 3 was similar to arm 4 but at room temperature, and arms 1 and 2 were sham SP to 3 and 4, respectively. For the final 2.5 h, participants remained in a semi-supine position. Each participant orally administered one 400-mg Advil Liqui-Gel® capsule. Blood samples were drawn over time and analyzed for (R)-ibuprofen and (S)-plasma ibuprofen concentrations using UPLC/MS/MS. Concentration-time data were analyzed by compartmental methods. RESULTS:Exercise significantly decreased the t(1/2abs) (h) of (S)-ibuprofen (0.26 to 0.17; p = 0.015) and T(max) (h) for both (R)-ibuprofen (0.97 to 0.73; p = 0.008) and (S)-ibuprofen (1.13 to 0.84; p = 0.005). Values for t(lag) (h) also decreased with exercise for both (R)-ibuprofen (0.38 to 0.22; p = 0.005), and (S)-ibuprofen (0.39 to 0.23; p = 0.001). CONCLUSIONS:Exercise stress had a significant impact on the absorption profile of (R)- and (S)-ibuprofen. Excessive self-administration rate and dose may not be due to the military operational stressors of heat and soldier presence patrol.
