Summary

Antihistamines are commonly used and currently levocetirizine is most frequently prescribed in the Netherlands. They are commonly used by divers, to solve ear, nose and throat problems, especially to open tubal passage. However, the effects of these drugs on cognitive performance have not been investigated during diving.The objective of this study is to investigate the effects of levocetirizine, hydroxyzine and placebo on cognitive and psychomotor functioning during controlled simulated diving in a hyperbaric chamber in professional navy divers at 10 mt (2 bar) and 30 mt (4 bar).It is hypothesized that hydroxyzine will produce significant impairment, and that the magnitude of impairment is related to hyperbaric pressure.
