Rexulti (Brexpiprazole Tablet) 0.5mg

Rexulti is primarily used in the management of mental health conditions. It acts on the serotonergic and dopaminergic pathways to provide therapeutic effects.

• Schizophrenia: Helps manage symptoms such as delusions, hallucinations, and disorganized thinking.
• Major Depressive Disorder (as adjunctive treatment): Used alongside antidepressants to improve mood and reduce depressive symptoms.
• Agitation in Alzheimer's Dementia: May be prescribed to manage agitation in patients with Alzheimer's disease.

• Brexpiprazole works as a partial agonist at 5-HT1A and D2 receptors and as an antagonist at 5-HT2A receptors. This modulation of serotonergic and dopaminergic neurotransmission helps to balance the chemical activity in the brain, which is crucial for managing symptoms of schizophrenia and major depressive disorder.

Rexulti, like other medications, can cause side effects, which can vary in severity and frequency.
