Zusammenfassung

Klinisch gebräuchliche Anästhetika besitzen amnestische, sedierende, hypnotische und immobilisierende Eigenschaften. Auf molekularer Ebene modulieren diese Substanzen eine Reihe von Rezeptoren in der Membran von Nervenzellen. Durch Untersuchungen an genetisch veränderten Tieren lässt sich nun erstmals eine Verbindung zwischen den Wirkungen an bestimmten Rezeptoren sowie den daraus resultierenden klinischen Wirkungen und Nebenwirkungen herstellen. So vermittelt ein Subtyp des GABAA-Rezeptors Bewusstseinsverlust und Immobilität; ein anderer Subtyp ist an Sedierung und Hypothermie beteiligt. Diese Erkenntnisse bilden eine Grundlage für die Entwicklung hochspezifischer, nebenwirkungsarmer Medikamente von morgen.
