title: R-(-)-deprenyl in the treatment of end-of-dose akinesia.
abstract: In two trials, we have studied the effectiveness and tolerability of L-deprenyl, a selective MAO B inhibitor, in the treatment of end of dose akinesia in patients with Parkinson's disease. The first trial was designed as an open controlled trial. In the L-deprenyl phase, an improvement in fluctuations in motor function as well as an overall reduction in the sum score of Webster's rating scale from 12.5 to 8.9 was observed, which almost returned to baseline during the placebo phase. The second trial was designed as a randomized trial comparing L-deprenyl therapy with a low-dose bromocriptine regimen. Both therapeutic approaches yielded the same results with respect to fluctuations; the CURS sum score dropped from 37 to 26. As regards tolerability, however, L-deprenyl was superior to bromocriptine.
