Abstract: Methods for treating a patient having pulmonary edema are described. The methods include administering to the lung endobronchial space of the airways of the patient an effective amount of a dopamine D1 receptor agonist. Dopamine D1 receptor agonists, including hexahydrobenzophenanthridine, hexahydrothienophenanthridine, phenyltetrahydrobenzazepine, chromenoisoquinoline, naphthoisoquinoline dopamine receptor agonists, and their pharmaceutically acceptable salts, formulated as aerosols and dry powders are also described.

Abstract: Methods for treating a patient having neurological, psychotic, and psychiatric disorders are described comprising the steps of administering to the patient an effective amount of a partial and/or full dopamine D1 receptor agonist, and administering to the patient an effective amount of a dopamine D2 receptor antagonist. Pharmaceutical compositions comprising a dopamine D1 receptor agonist and a dopamine D2 receptor antagonist are also described. The D1 dopamine receptor agonist and the D2 dopamine receptor antagonist can be administered to the patient in the same or in a different composition or compositions.

Abstract: The present invention relates to the treatment of dopamine-related dysfunction using full D1 dopamine receptor agonists in an intermittent dosing protocol with a short, but essential, “off-period.” The D1 agonist concentration is reduced during the “off-period” to obtain a plasma concentration of agonist that suboptimally activates D1 dopamine receptors for a period of time to prevent induction of tolerance. Specifically, the method comprises the steps of periodically administering to a patient a full D1 agonist with a half-life of up to about 6 hours at a dose resulting in a first plasma concentration of agonist capable of activating D1 dopamine receptors to produce a therapeutic effect. The dose is reduced at least once every 24 hours to obtain a second lower plasma concentration of agonist that results in suboptimal activation of D1 dopamine receptors for a period of time sufficient to prevent induction of tolerance.

Abstract: Novel dopamine receptor ligands of the formula: pharmaceutical formulations of such compounds, and a method using such compounds for treating a patient suffering from dopamine-related dysfunction of the central or peripheral nervous system, are described. The compounds are expected to be useful in treating Parkinson's disease, improving cognition, improving memory, improving the negative symptoms of schizophrenia, improving attention-deficit hyperactivity disorder and related developmental disorders, treating substance abuse disorders, and in treating various peripheral conditions where changes in dopamine receptor occupation affects physiological function, including organ perfusion, cardiovascular function, and selected endocrine and immune system functions.

Abstract: The present invention is directed to a novel dopamine receptor ligands of the formula: pharmaceutical formulations of such compounds, and a method using such compounds for treating a patient suffering from dopamine-related dysfunction of the central or peripheral nervous system.
