Early administration of tiapride to young rats without long-lasting changes in the development of the dopaminergic system.

Background: The benzamide tiapride, a selective dopamine D2/D3-receptor antagonist, can be used effectively in children to treat tic disorders and stuttering. Tiapride is a clinically safe substance (even during long-term treatment and when given to young children). Unfortunately, its probable effects on general brain development and the maturation of the dopaminergic system have not been investigated.
