[Requirement of an "ideal" drug for prevention of space motion sickness].

The range of effects and mechanisms of action of drugs that are promising in terms of the development of a potent and low toxicity drug to prevent space motion sickness was identified. The use of anticonvulsive and adaptogenic drugs as a prophylactic measure of the syndrome was theoretically confirmed. In human studies these drugs were shown to exert a noticeable effect on statokinetic stability and mental performance. Possible mechanisms of anti-motion++ action of the drugs are described. Requirements for an ideal drug to prevent space motion sickness are formulated.
