Identification
- Summary
Brexpiprazole is a serotonin–dopamine activity modulator used in the treatment of major depressive disorder as an adjunct and schizophrenia.
- Brand Names
- Rexulti
- Generic Name
- Brexpiprazole
- DrugBank Accession Number
- DB09128
- Background
Brexpiprazole is a novel D2 dopamine and serotonin 1A partial agonist, called serotonin-dopamine activity modulator (SDAM), and a potent antagonist of serotonin 2A receptors, noradrenergic alpha 1B and 2C receptors. Brexpiprazole is approved for the treatment of schizophrenia, and as an adjunctive treatment for major depressive disorder (MDD). Although it failed Phase II clinical trials for ADHD, it has been designed to provide improved efficacy and tolerability (e.g., less akathisia, restlessness and/or insomnia) over established adjunctive treatments for major depressive disorder (MDD).

- Mechanism of action
Although the mechanism of action of brexpiprazole in the treatment of MDD and schizophrenia is unclear, the efficacy of brexpiprazole may be attributed to partial agonist activity at serotonin 1A and dopamine D2 receptors, and antagonist activity at serotonin 2A receptors.
Target Actions Organism A5-hydroxytryptamine receptor 1A agonistpartial agonistHumans ADopamine D2 receptor agonistpartial agonistHumans A5-hydroxytryptamine receptor 2A antagonistHumans AAlpha-2C adrenergic receptor antagonistHumans AAlpha-1B adrenergic receptor antagonistHumans - Absorption
Brexpiprazole reaches peak plasma concentration within 4 hours of administration, and steady state occurs within 10-12 days of dosing. Oral bioavailability is 95%, and can be administered with or without food.
- Volume of distribution
Intravenous volume of distribution is 1.56L/kg.
- Protein binding
>99% protein bound in plasma to serum albumin and α1-acid glycoprotein. Based on in vitro studies, protein binding is not affected by warfarin, diazepam, or digitoxin.
- Metabolism
Metabolized mainly by CYP3A4 and CYP2D6 enzymes into its major metabolite, DM-3411. DM-3411 is not considered to contribute any therapeutic effect.

- Route of elimination
Approximately 25% urinary and 46% fecal excretion. <1% and ~14% of the unchanged drug was recovered in the urine and feces, respectively.
- Half-life
Brexpiprazole and its major metabolite, DM-3411 have half lives of 91 and 96 hours respectively.
- Clearance
19.8mL/h/kg
