title: Experimental motion sickness: efficacy of transdermal scopolamine plus ephedrine.
abstract: A double-blind, placebo-controlled study compared the efficacy of transdermal therapeutic system-scopolamine administered alone and combined with ephedrine sulfate given orally in doses of 12.5, 25, and 50 mg. Eight normal male students were exposed to stressful accelerations in a slow-rotation room after receiving 10 apparently identical treatments comprising the four drugs and six placebos. Efficacy of the drug was defined in terms of the placebo range and categorized as beneficial, inconsequential, or detrimental. None of the effects was detrimental. Overall beneficial effects were 60% for transdermal therapeutic system-scopolamine (plus placebo) and 57% for the three transdermal therapeutic system-scopolamine plus ephedrine combinations.
