Physical and Chemical Properties | Bioactive Brexpiprazole(OPC-34712) is a new type of dopamine receptor D2 and serotonin 1A receptor partial agonist, and is also an antagonist of serotonin 2A receptor, norepinephrine alpha1B and alpha2C receptor. Its Ki values for D2L,5-HT1A,5-HT2A,α1B receptor and α2C receptor were 0.3,0.12,0.47,0.17 and 0.59nM, respectively. |
Use | Application of epizole can be used for major depression, schizophrenia adjuvant therapy medication. |
In vitro study | Brexpiperazole is a potent partial activator of human serotonin 5-HT1A(Ki = 0.12 nM) and dopamine receptor D2L(Ki = 0.3 nM). It is also an antagonist of the 5-HT2A receptor (Ki = 0.47 nM). It also has antagonistic activity against human norepinephrine receptors α1B(Ki = 0.17 nM) and α2C(Ki = 0.59 nM). In addition, brexpiperazole has moderate affinity for human D3, 5-HT2B, 5-HT7, α1A and α1D adrenergic receptors. In PC12 cells, it enhances NGF-induced neurite outgrowth and enhances the effect of fluoxetine on neurite outgrowth. |
In vivo study | Brexpiperazole can improve PCP-191 caused by Cognitive Disorder in mice through the 5-HT1A receptor. |

Summary:
The present invention relates to a technology for improving the solubility of the insoluble drug ipiperazole and the preparation of ipiperazole tablets, belonging to the technical field of pharmaceutical preparations. Epiprazole is used as the active ingredient of the drug for airflow crushing, and then hydrophilic excipients are used to make solid dispersion, which can ensure the highly dispersed state of the drug, effectively improve the solubility and dissolution rate of the insoluble drug, thereby improving the bioavailability of the drug. Then the solid dispersion is further prepared into tablets to promote the absorption of the drug in the body, and further improve the bioavailability of the drug, and its preparation process is simple, avoiding dust pollution, easy industrial production, and enhancing the compliance of patients with medication.
