Abstract: This study examined the effects of 30 minutes of cycle exercise at 65% V̇O2max on the pharmacokinetics of the S.S.R.I. sertraline. Blood samples were taken over 48 hours from 14 healthy males (23.9±2.5 years, 80.3±12.6 kilograms) following oral ingestion of a single 100 mg dose of sertraline. Participants completed two sertraline trials separated by at least two weeks; one trial while resting and the other trial with exercise as described above. With exercise, the absorption rate constant and volume of sertraline in the central compartment decreased, while the elimination half-life increased. Maximum concentration, time of maximum concentration, and area under the curve were unchanged. Fitness level had little impact on the concentration of sertraline, as compartmental modeling was unchanged when relative V̇O2max was added as a covariate. However, controlling for participant body weight improved the model estimate. These results indicate that acute aerobic exercise has the potential to change the concentration of sertraline in vivo.
