Abstract

Behavioral pharmacological data with the compound of formula (I), a novel and selective 5HT2A/2C receptor inverse agonist, demonstrate in vivo efficacy in models of psychosis and dyskinesias. This includes activity in reversing MK-801 induced locomotor behaviors, suggesting that this compound may be an efficacious anti-psychotic, and activity in an MPTP primate model of dyskinesias, suggesting efficacy as an anti-dyskinesia agent. These data support the hypothesis that 5HT2A/2C receptor inverse agonism may confer antipsychotic and anti-dyskinetic efficacy in humans, and indicate a use of the compound of formula (I) and related agents as novel therapeutics for Parkinson's Disease, related human neurodegenerative diseases, and psychosis.

First claim

What is claimed is:

1. A method for treating hallucinations or delusions comprising administering to a patient a therapeutically effective amount of a compound of Formula (I) or a salt thereof:

2. The method of claim 1 , wherein the hallucinations or delusions are associated with Parkinson's disease psychosis.

3. The method of claim 1 , wherein the patient is treated for Parkinson's disease psychosis.

4. The method of claim 1 , wherein the method is for treating hallucinations and delusions in the patient.

5. The method of claim 1 , wherein a tartrate salt of the compound of Formula (I) is administered to the patient.

6. The method of claim 5 , wherein the tartrate salt of the compound of Formula (I) in an amount of about 0.001 mg to about 50 mg is administered to the patient.

7. The method of claim 5 , wherein the tartrate salt of the compound of Formula (I) in an amount of about 15 mg is administered to the patient.

8. The method of claim 5 , wherein the tartrate salt of the compound of Formula (I) in an amount of about 25 mg is administered to the patient.

9. The method of claim 5 , wherein the tartrate salt of the compound of Formula (I) in an amount of about 50 mg is administered to the patient.

10. The method of claim 5 , wherein the tartrate salt of the compound of Formula (I) is administered daily.

11. The method of claim 5 , wherein the tartrate salt of compound of Formula (I) is administered once daily.

12. The method of claim 5 , wherein the tartrate salt of compound of Formula (I) is administered two times daily.

13. The method of claim 5 , wherein the tartrate salt of compound of Formula (I) is formulated for oral administration as a unit dose.

14. The method of claim 13 , wherein the unit dose is a tablet.

15. The method of claim 1 , wherein the therapeutically effective amount of the compound of Formula (I) or a salt thereof is from 0.01 mg/kg of body weight per day to 100 mg/kg of body weight per day.
