Zusammenfassung
Die antipsychotische Wirkung von Neuroleptika ist gut belegt. Die weithin anerkannte Hypothese zur Wirkungsweise von Antipsychotika besagt, daß der Effekt der Neuroleptika in Beziehung steht zu ihrer Fähigkeit, den Neurotransmitter Dopamin zu antagonisieren (Carlsson u. Lindqvist 1963; van Rossum 1966). Die Entwicklung von Radioligandenbindungstechniken und die Verfügbarkeit 3H-markierter Neuroleptika ermöglichte die Untersuchung der Bindungsstellen für Neuroleptika in Hirnhomogenaten und Hirnschnitten. Erhärtet wurde die Dopaminhypothese durch den Nachweis einer linearen Korrelation zwischen der an Tierhirnen in vitro ermittelten Affinität einer Substanz für den D2-Subtyp des Dopaminrezeptors und ihrer klinischen antipsychotischen Wirksamkeit beim Menschen (Creese et al. 1976; Seeman et al. 1976).
