RP5063

RP5063

RP5063, also known as RP5000, is an investigational atypical antipsychotic which is under development by Reviva Pharmaceuticals for the treatment of schizophrenia and schizoaffective disorder.[1][2][3][4] Reviva Pharmaceuticals also intends to investigate RP5063 for the treatment of bipolar disorder, major depressive disorder, psychosis/agitation associated with Alzheimer's disease, Parkinson's disease psychosis, attention deficit hyperactivity disorder (ADD/ADHD), and autism.[5][6] As of May 2015, it is in phase III clinical trials for schizophrenia.[5][6]

Pharmacodynamics

RP5063 is frequently described as a so-called "dopamine-serotonin system stabilizer" due to its unique actions on the dopamine and serotonin neurotransmitter systems compared to other antipsychotics.[4][7] Specifically, it acts as a partial agonist of the D2, D3, and D4 receptors and of the 5-HT1A and 5-HT2A receptors, and as an antagonist of the 5-HT6 and 5-HT7 receptors.[3][4][7] RP5063 has high affinity for the D2S, D2L, D3, D4.4, 5-HT1A, 5-HT2A, 5-HT7, and H1 receptors, and moderate affinity for the D1, D5, 5-HT3, 5-HT6 receptors, the SERT, and the α1B-adrenergic receptor.[7] It lacks significant affinity for the 5-HT1B, 5-HT2C, α2-adrenergic, and mACh receptors, as well as for the NET and DAT.[7][8]
