- DB09128
- Background
Brexpiprazole is an atypical antipsychotic and a novel D2 dopamine and serotonin 1A partial agonist called serotonin-dopamine activity modulator (SDAM). It has a high affinity for serotonin, dopamine and alpha (α)-adrenergic receptors.8 Although it is structurally similar to aripiprazole, brexpiprazole has different binding affinities for dopamine and serotonin receptors. Compared to aripiprazole, brexpiprazole has less potential for partial agonist-mediated adverse effects such as extrapyramidal symptoms, which is attributed to lower intrinsic activity at the D2 receptor. It also displays stronger antagonism at the 5-HT1A and 5-HT2A receptors.2,5,6
Brexpiprazole was first approved by the FDA on July 10, 2015.2 Currently approved for the treatment of depression, schizophrenia, and agitation associated with dementia due to Alzheimer’s disease, brexpiprazole has also been investigated in other psychiatric disorders, such as post-traumatic stress disorder.1

Pharmacology
- Indication
Brexpiprazole is indicated as adjunctive therapy to antidepressants for the treatment of major depressive disorder in adults.7 It is also indicated for the treatment of schizophrenia in patients 13 years of age and older.7
Brexpiprazole is also indicated for the treatment of agitation associated with dementia due to Alzheimer’s disease; however, it is not indicated as an as-needed (“prn”) treatment for this condition.8

Brexpiprazole is an atypical antipsychotic agent used to ameliorate the symptoms of psychiatric conditions, such as cognitive deficits and affective symptoms.2 Brexpiprazole has affinity (expressed as Ki) for multiple monoaminergic receptors including serotonin 5-HT1A (0.12 nM), 5-HT2A (0.47 nM), 5-HT2B (1.9 nM), 5-HT7 (3.7 nM), dopamine D2 (0.30 nM), D3 (1.1 nM), and noradrenergic α1A (3.8 nM), α1B (0.17 nM), α1D (2.6 nM), and α2C (0.59 nM) receptors. Brexpiprazole acts as a partial agonist at the 5-HT1A, D2, and D3 receptors and as an antagonist at 5-HT2A, 5-HT2B, 5-HT7, α1A, α1B, α1D, and α2C receptors. Brexpiprazole also exhibits affinity for histamine H1 receptor (19 nM) and for muscarinic M1 receptor (67% inhibition at 10 µM).8
- Mechanism of action
Although the exact mechanism of action of brexpiprazole in psychiatric disorders has not been fully elucidated, the efficacy of brexpiprazole may be attributed to combined partial agonist activity at 5-HT1A and dopamine D2 receptors, and antagonist activity at 5-HT2A receptors. Brexpiprazole binds to these receptors with subnanomolar affinities.1,3,8 These therapeutic targets have been implicated in psychiatric conditions such as schizophrenia and depression. Partial D2 receptor agonism allows the drug to stimulate D2 receptors under low dopamine conditions, while attenuating their activation when dopamine levels are high. Partial agonism at 5-HT1A receptors may be tied to improved memory function and cognitive performance. Antagonism at α-adrenergic receptors has also been implicated in schizophrenia and depression.2,4

After a single-dose administration, the Tmax was four hours and the absolute oral bioavailability was 95%. Brexpiprazole steady-state concentrations were attained within 10 to 12 days of dosing. After single and multiple once-daily dose administration, the Cmax and AUC increased dose-proportionally.8
A high-fat meal did not significantly affect the Cmax or AUC of brexpiprazole.8
- Volume of distribution
The volume of distribution of brexpiprazole following intravenous administration is 1.56 ± 0.42 L/kg, indicating extravascular distribution.8
- Protein binding
In vitro, brexpiprazole was 99% bound to plasma proteins, mainly serum albumin and α1-acid glycoprotein.8
- Metabolism
According to in vitro studies, brexpiprazole is mainly metabolized by CYP3A4 and CYP2D6. Brexpiprazole and its major metabolite, DM-3411, were the predominant drug moieties in the systemic circulation following single and multiple dose administration. At steady-state, DM-3411 represented 23% to 48% of brexpiprazole exposure (AUC) in plasma. DM-3411 is considered not to be pharmacologically active.8

- Route of elimination
Following a single oral dose of radiolabeled brexpiprazole, approximately 25% and 46% of radioactivity was recovered in the urine and feces, respectively. Less than 1% of unchanged brexpiprazole was excreted in the urine, and approximately 14% of the oral dose was recovered unchanged in the feces.8
- Half-life
After multiple once-daily administrations, the terminal elimination half-lives of brexpiprazole and its major metabolite, DM-3411, were 91 hours and 86 hours, respectively.8
- Clearance
Apparent oral clearance of brexpiprazole after once-daily administration is 19.8 (±11.4) mL/h/kg.8

There is limited information regarding acute toxicity and human overdosage with brexpiprazole. Management of overdose should concentrate on supportive therapy, maintaining an adequate airway, oxygenation and ventilation, and management of symptoms. Close medical supervision and monitoring should continue until the patient recovers. Oral activated charcoal and sorbitol (50 g/240 mL), administered one hour after ingesting oral brexpiprazole, decreased brexpiprazole Cmax and area under the curve (AUC) by approximately 5% to 23% and 31% to 39% respectively; however, there is insufficient information available on the therapeutic potential of activated charcoal in treating an overdose with brexpiprazole. There is no information on the effect of hemodialysis in treating an overdose with brexpiprazole; hemodialysis is unlikely to be useful because brexpiprazole is highly bound to plasma proteins.8
