[Clinical study of a new agent correcting the syndrome of neuroleptic impregnation in acute psychotic states]

Abstract

The correcting action of tropatepine hydrochloride upon the extrapyramidal effects induced by neuroleptics has been studied in 32 acute psychotic states. A satisfying result has been obtained with daily doses of 10 to 20 mg in 30 cases (excellent results: 20, good results: 10 patients). The action upon dyskinetic crises is particularly good and quickly obtained, avoiding a recourse to an i.m. corrector in 7 cases out of 8. The akineto-hypertonic syndrome has been efficiently corrected in 18 cases out of 23. The hyperkinetic manifestations (akathisia, tasikinesia) reacted favourably in 8 cases out of 11, dysarthria in 7 cases out of 11. The lessening of tremor was less satisfying (8 cases out of 15); same thing for the dryness of the mouth (7 cases out of 16) and disorder of visual accomodation (6 cases out of 12). The clinical tolerance was excellent. With the used doses, we found neither inconvenient atropinic effect, nor disorder of the vigilance, nor pharmacodependence. The one daily administration of a 10 mg tablet turned out to be sufficient in 19 cases. This possibility of only one administration a day appeared to us as a great advantage.
