schizophrenia

5-hydroxytryptamine receptor 2C shows approved-linked disease relevance led by schizophrenia. 5 more disease programs remain visible in the same review block. 13 linked drugs remain visible in the same block.

Start review with schizophrenia because it currently carries approved-linked support. Linked drugs include AGOMELATINE, CHLORPROTHIXENE, LOXAPINE, LOXAPINE SUCCINATE. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
