Psychosen, wozu auch Krankheiten aus dem Formkreis der Schizophrenie gehören, wurden auf eine Überaktivität des limbischen Dopaminsystems zurückgeführt (Snyder et al., Science 184: 1243-1253, 1974). Der antipsychotische Effekt von Neuroleptika wurde auf ihre D2-antagonistischen Eigenschaften zurückgeführt (bezüglich der Nomenklatur der Rezeptoren:and their salts and solvates. Psychoses, including diseases from the schizophrenia category, have been attributed to overactivity of the limbic dopamine system (Snyder et al., Science 184: 1243-1253, 1974). The antipsychotic effect of neuroleptics was attributed to their D 2 -antagonistic properties (regarding the nomenclature of the receptors:
Basic Neurochemistry, Herausgeber: G. J. Siegel, B. W. Agranoff, R. W. Albers, P. B. Molinoff, 5. Auflage, Raven Press, Ltd., N. Y. USA, Kapitel 12 und 13; im übrigen folgende Fachaufsätze: Creese et al., Science 192: 481-483, 1976; Farde et al., Psychopharmacoiogy 99: 28-31 , 1989; Feeman et al., Nature 261 : 717-719, 1976; Wiesel et al., Prog. Neuro- Psychopharmacol. & Biol. Psychiat. 14: 759-767, 1990). Folglich wurde die klassische Dopamin-Hypothese der Schizophrenie aufgestellt, nach der Neuroleptika an den D2-Rezeptor zu binden haben. Der Einsatz klassischer D2-Antagonisten ist aufgrund ihrer extrapyramidalen Neben- Wirkungen vor allen Dingen bei chronischer Verabreichung stark eingeschränkt. Zu den extrapyramidalen Nebenwirkungen gehören z.B. Tremor, Akinesie, Dystonie und Akathisie (Cavallaro & Smeraldi, CNS Drugs 4: 278-293, 995). Es gibt nur wenige Antipsychotika, die wesentlich weniger oder gar keine extrapyramidale Nebenwirkungen hervorrufen und die als „atypische Neuroleptika" bezeichnet werden (Kervin, Brit. J. Psychiatry 1964, 141-148, 1994). Das prototypische atypische Neuroleptikum Clozapin hat extrem geringe extrapyramidale Nebenwirkungen, verursacht aber andere gravierende Komplikationen wie die zuweilen tödliche Agranulocytose (Alvir et al., New Engl. J. Med. 329: 162-167, 1993).Basic Neurochemistry, editors: GJ Siegel, BW Agranoff, RW Albers, PB Molinoff, 5th edition, Raven Press, Ltd., NY USA, chapters 12 and 13; the following technical articles: Creese et al., Science 192: 481-483, 1976; Farde et al., Psychopharmacoiogy 99: 28-31, 1989; Feeman et al., Nature 261: 717-719, 1976; Wiesel et al., Prog. Neuro- Psychopharmacol. & Biol. Psychiat. 14: 759-767, 1990). Consequently, the classic dopamine hypothesis of schizophrenia was established, according to which neuroleptics have to bind to the D 2 receptor. The use of classic D 2 antagonists is severely restricted due to their extrapyramidal side effects, especially with chronic administration. The extrapyramidal side effects include, for example, tremor, akinesia, dystonia and akathisia (Cavallaro & Smeraldi, CNS Drugs 4: 278-293, 995).

Transm. 74: 195-198, 1988) und die durch Dopamin-D2- Antagonisten induzierte Katalepsie (Costall et al., Neuropharmacology 14: 859-868, 1975) verhindern, könnten 5-HTιA~agonistische Eigenschaften von Vorteil sein. Die Wirksamkeit von Buspiron, ein Pharmakon mit 5-HTiA-agonistischen und Dopamin-D2-antagonistischen Eigenschaften, wurde bei Schizophrenie-Patienten nachgewiesen (Goff et al., J. Clin, Psychopharmacol. 11 : 193-197, 1991). Außer verschiedenen Dopamin- Autorezeptoragonisten, die auch für den 5-HTiA-Rezeptor eine signifikante Affinität aufweisen (z.B.

Arch. Pharmacol. 344: 509-513, 1991), PD1431188 (Melzer et al., J.Because 5-HT 1A agonists in animals increase the antipsychotic properties of conventional dopamine D 2 antagonists (Wadenberg & Ahlenios, J.

The effectiveness of buspirone, a drug with 5-HTi A agonistic and dopamine D 2 antagonistic properties, has been demonstrated in schizophrenia patients (Goff et al., J. Clin, Psychopharmacol. 11: 193-197, 1991). In addition to various dopamine autoreceptor agonists, which also have a significant affinity for the 5-HTiA receptor (for example U-86170F, Lahti et al., Naunyn-Schmiedeberg's Arch.

Eine Dosis zwischen 10 und 50 mg pro Dosiseinheit wird für andere Indikationen bevorzugt. Allerdings hängt die zu verabreichende Dosis von einer Vielzahl von Faktoren ab, z.B. von der Wirksamkeit der entsprechenden Komponente, dem Alter, dem Körpergewicht und der allgemeinen Verfassung des Patienten.The substances of the general formula I are normally administered analogously to known, commercially available pharmaceutical preparations (for example bromocriptine and dihydroergocornine), preferably in doses of between 0.2 and 500 mg, in particular between 0.2 and 15 mg, per dose unit.

Low doses (between 0.2 and 1 mg per dose unit, 0.001 to 0.005 mg per kg body weight) are particularly suitable for pharmaceutical preparations for the treatment of migraines. A dose between 10 and 50 mg per dose unit is preferred for other indications. However, the dose to be administered depends on a variety of factors, e.g. the effectiveness of the relevant component, the age, body weight and general condition of the patient.

Die Erfindung wird durch die nachfolgenden Beispiele beschrieben.The invention is described by the following examples.
Das Molekulargewicht (M+H+) wird mit Hilfe von Elektronenspray- lonisationsmassenspektroskopie bestimmt. Die massenspektroskopischen Daten stammen aus HPLC/MS-Läufen (HPLC gekoppelt mit einem Elektrospray-Ionisationsmassenspektrometer). Die Zahlenwerte sind, wie bei diesem Verfahren üblich, nicht die Molekulargewichte der unveränderten Verbindungen, sondern die Molekulargewichte der
protonierten Verbindungen (im folgenden: [M+H]+). Die Methode ist in folgenden Literaturstellen beschrieben: M. Yamashita, J. B. Fenn, J. Phys. Chem. 88, 1984, 4451-4459; C. K. Meng et al., Zeitschrift für Physik D 10, 1988, 361-368; J. B. Fenn et al., Science 246, 1989, 64-71.The molecular weight (M + H + ) is determined with the help of electron spray ionization mass spectroscopy. The mass spectroscopic data come from HPLC / MS runs (HPLC coupled with an electrospray ionization mass spectrometer). As is usual in this process, the numerical values are not the molecular weights of the unchanged compounds, but rather the molecular weights of the protonated compounds (hereinafter: [M + H] + ). The method is described in the following references: M. Yamashita, JB Fenn, J. Phys. Chem. 88, 1984, 4451-4459; CK Meng et al., Zeitschrift für Physik D 10, 1988, 361-368; JB Fenn et al., Science 246, 1989, 64-71.
