[Treatment of abnormal movements of extrapyramidal origin with tiapride].

The authors report results attained by means of a replaced benzamide, thiapride, in the treatment of 21 subjects showing involuntary movements of extra-pyramidal origin and more exactly: extra-pyramidal syndromes due to drugs (3), idiopathic dyscinesias (8), choreas (6), dystonias (3), essential tremor (1). The drug was administered per os as well as per IM and EV. Results were good or fair in 71% of cases. The clearest improvements were obtained in iatrogenic dyscinesias (torticollis, diaphragm clonisms). The drug was well tolerated in all cases, both from the clinical and hematochemical standpoint, even at the highest dosages, and, in particular, no case of amenorrhea or galactorrhea was pointed out. Finally, the authors explain how the best results with thiapride may probably be obtained in those forms in which an hyperfunction of the dopaminergic system is proved, thanks to the competitive action of the molecule on presynaptic dopaminergic receptors.
