[Evaluation of the effect of anti-motion sickness pharmaceuticals on adaptation to the model conditions of long-term rotation].

A reduced prescription of preparation P-4 (one close 1,5-2 hrs. before, the other in 2 hrs. after the test had begun) proved to have a high preventive effect in human subjects during 4-hrs. exposure in a slow-rotating room. The preparation mitigated the main motion sickness symptoms and accelerated adaptation.
