Twenty patients with Parkinsonism were investigated in order to establish whether the gradual introduction of treatment with levodopa allows a higher dose to be tolerated than can be achieved if treatment is introduced rapidly. No indication was obtained that slow introduction of treatment offers an advantage in maximum tolerated dose, and patients aged 65 and over responded similarly in this respect to those under 65. The maximum tolerated dose is slightly lower in the elderly patient. The incidence of the different side effects does not appear to be affected by the rate of increasing the dose of levodopa.
对20名帕金森病患者进行了调查,以确定与快速开始治疗相比,逐渐引入左旋多巴治疗是否能使患者耐受更高的剂量。没有迹象表明缓慢开始治疗在最大耐受剂量方面具有优势,65岁及以上的患者在这方面的反应与65岁以下的患者相似。老年患者的最大耐受剂量略低。左旋多巴剂量增加的速度似乎不会影响不同副作用的发生率。
