In a double-blind, placebo-controlled study with co-dergocrine in the treatment of tardive dyskinesia in a group of elderly chronic psychiatric patients the reduction of dyskinetic scores in the group receiving active medication was slightly greater than that in the placebo group; however, this difference did not reach a level of statistical significance. It is suggested that further work could be undertaken with a longer period of treatment, and at a higher dosage level of co-dergocrine, in a younger patient sample.
