Rexulti 2 mg Tablets is a prescription-only atypical antipsychotic used to treat major psychiatric disorders. This medication contains brexpiprazole, a serotonin-dopamine modulator that helps restore chemical balance in the brain. Rexulti is widely prescribed for adults with schizophrenia and as an adjunctive therapy for major depressive disorder (MDD) when antidepressant treatment alone is not sufficient.

How Rexulti Works

This pharmacological profile makes Rexulti effective for both psychotic disorders and depression augmentation therapy.
