内耳前庭受到刺激之后出现眩晕、冷汗、面色苍白、恶心和呕吐等症状,总称为前庭植物神经反应。这些症状危害病人,造成病人的极端痛苦,因此有人研究抵抗眩晕的药物,这些药物同时既是减弱前庭植物神经反应的药物,也是抗运动病的药物。国外研究这类药物多采用人工刺激前庭器官诱发出症状之后,再用药物去抑制这些症状,以评价药物的效果。他们采用过的药物有:东莨菪硷、苯异丙胺、氯茶硷苯海拉明和导丙嗪等。其作用机制在于阻滞乙酰胆硷和增强肾上腺素在中枢神经系统的活动。这些药物均系人工综合药物,有较强的副作用,或引起口干、嗜睡,或引起困
After the stimulation of the vestibular inner ear, dizziness, cold sweat, pale, nausea and vomiting and other symptoms, collectively known as vestibular nerve response. These symptoms endanger the patient, causing extreme suffering to the patient. Therefore, some people study anti-dizziness drugs, which are both drugs that attenuate the nerve response of the vestibular plant and are also anti-exercise drugs. Foreign study of such drugs and more artificial stimulation of vestibular organs induced symptoms, then use drugs to inhibit these symptoms to evaluate the effect of drugs. The drugs they used were: scopolamine, amphetamine, chlorhexidine diphenhydramine and promethazine. Its mechanism of action is to block the acetylcholine and enhance epinephrine in the central nervous system activity. These drugs are artificial synthetic drugs, have strong side effects, or cause dry mouth, drowsiness, or cause trouble
