Substituted pyrido[3',4':4,5]pyrrolo[1,2,3-de]quinoxalines for inhibiting serotonin reuptake transporter activity
The invention relates to substituted heterocycle fused gamma-carbolines of the Formula Q as described herein, in free base or pharmaceutically acceptable salt form, and/or pharmaceutical compositions thereof, and methods of use in the treatment of diseases involving the 5-HT 2A receptor pathway, the serotonin transporter (SERT) pathway and/or the dopamine D 2 receptor pathway signaling systems.
1. A method for inhibiting serotonin reuptake transporter activity in a patient, comprising administering to a patient in need thereof a therapeutically effective amount of a pharmaceutical composition comprising:
(i) a compound of Formula Q:
wherein:
X is —N(H)— or —N(CH 3 )—; and
Y is —C(═O)— or —O—;
in free base or pharmaceutically acceptable salt form, and
(ii) a polymeric matrix which comprises polymers selected from a group consisting of poly(glycolic acid), poly-D,L-lactic acid and poly-L-lactic acid, or copolymers thereof.
2. The method according to claim 1 , wherein said patient has a disorder involving the serotonin (5-hydroxytryptamine) 2A pathway, the dopamine D2 receptor pathway and/or the serotonin reuptake transporter pathway.
3. The method according to claim 2 , wherein said disorder is selected from a group consisting of (1) psychosis in a patient suffering from depression, (2) depression in a patient suffering from psychosis, (3) a mood disorder associated with psychosis, and (4) a sleep disorder associated with psychosis.
4. The method according to claim 1 , wherein said patient has a disorder selected from a group consisting of obesity, anxiety, depression, psychosis, schizophrenia, migraine, a sleep disorder, a sexual disorder, a gastrointestinal disorder, a condition associated with cephalic pain, a social phobia, an agitation in dementia and an agitation in autism and related autistic disorders.
5. The method according to claim 4 , wherein the disorder is depression.
6. The method according to claim 4 , wherein the disorder is psychosis.
7. The method according to claim 4 , wherein the disorder is schizophrenia.
