Non-neuroleptic catecholaminergic drugs for neuroleptic-induced tardive dyskinesia.

Tardive dyskinesia (TD) is a disabling movement disorder associated with the prolonged use of neuroleptic medication. Several strategies have been examined in the treatment of TD. Currently, however, there is no clear evidence of the effectiveness of these drugs in TD and they have been associated with many side effects. One particular strategy would be to use pharmaceutical agents which are known to influence the catecholaminergic system at various junctures.
