Amantadine, administered at a dose of 200 mg/day, antagonized the extapyramidal symptomatology induced by neuroleptic drugs in fifteen psychiatric patients. Steady-state levels were reached within 4-7 days of treatment. Individual plasma levels ranged from 200-900 ng/ml. Apparent plasma half-lives varied from 10-28.5 h with an apparent VD of 200-400 litres. A significant relationship was found between the plasma levels of amantadine and the effects on the extrapyramidal symptomatology. The data suggest a direct effect of amantadine on dopaminergic receptors.
金刚烷胺以每日200毫克的剂量给药,可对抗15名精神病患者中由抗精神病药物引起的锥体外系症状。治疗4至7天内达到稳态水平。个体血浆水平在200 - 900纳克/毫升之间。表观血浆半衰期在10 - 28.5小时之间,表观分布容积为200 - 400升。发现金刚烷胺的血浆水平与对锥体外系症状的影响之间存在显著关系。数据表明金刚烷胺对多巴胺能受体有直接作用。
