Compare Rexulti vs Latuda:
Antipsychotics are psychiatric drugs that are available on prescription, and are licensed to treat the following mental health problems:
- severe depression;
- agitation and psychotic experiences in dementia;
- some forms of bipolar disorder;
- problems with balance and nausea;
- schizoaffective disorder;
- persistent hiccups;
- severe anxiety.
Notes – combining antipsychotic medication with support and other therapy can help sufferers to improve their quality of life and manage symptoms.
Antipsychotic medications can also help to clear confusion in an individual with acute psychosis within several days, however, they can take up to 6 weeks to reach their full effect.
List of antipsychotics include:
- aripiprazole (Abilify);
- risperidone (Risperdal);
- asenapine (Saphris);
- loxapine (Loxitane);
- olanzapine (Zyprexa);
- thiothixene (Navane);
- cariprazine (Vraylar);
- molindone (Moban);
- clozapine (Clozaril);
- perphenazine (Trilafon);
- quetiapine (Seroquel);
- trifluoperazine (Stelazine);
- mesoridazine (Serentil);
- ziprasidone (Geodon);
- fluphenazine (Prolixin);
- thioridazine (Mellaril);
- haloperidol (Haldol).
Note – there are two main types of antipsychotics: older antipsychotics (which have been used since the 1950s) and atypical antipsychotics (developed in the 1970s onwards).
Both types are thought to work equally well.
Here is a comparison between Rexulti and Latuda, two atypical antipsychotic drugs:
Rexulti (brexpiprazole) belongs to the family of drugs known as second-generation psychotics or atypical antipsychotics.
It was first approved by the US FDA to treat schizophrenia in 2015.
Additionally, it is approved as an adjunctive option for major depressive disorder.
Latuda (lurasidone) is an atypical antipsychotic that has been approved by the US FDA since 2010 for the treatment of schizophrenia in adults.
In 2013, the FDA approved it as a potential treatment for bipolar depression.
It is indicated in adult patients for the treatment of schizophrenia.
The medication does not cure schizophrenia, however, it helps to manage symptoms by affecting the actions of certain neurotransmitters in the brain.
Additionally, it can be given in combination with an antidepressant to treat depression in adults.
Note – it will probably take a few weeks to see changes in your symptoms to decide if this drug is the right medication for you.
It is used to treat adults with schizophrenia. The drug typically starts providing relief within one month.
Also, it may be helpful for agitation associated with dementia and major depressive disorder psychosis.

Bottom Line – Rexulti vs Latuda
Rexulti (brexpiprazole) is a prescription medication that belongs to a family of drugs called atypical antipsychotics. It is used to treat the symptoms of schizophrenia and major depressive disorder in adults.
It has substantial effects on the D2 dopaminergic receptors (a primary target for most antipsychotic agents) and on the serotonergic receptors (5-HT2A and 5-HT1A).
Latuda (lurasidone) is an atypical antipsychotic which was first approved in 2010 for people living with schizophrenia.
Furthermore, it is occasionally indicated to treat depressive symptoms in bipolar disorder. The biggest disadvantages of this drug are the potential long-term side effects, which can include tardive hyperglycemia, dyskinesia, and weight gain.
A 2018 study that looked to assess the relative efficacy and metabolic effects of brexpiprazole and lurasidone in the acute treatment of schizophrenia established that both drugs had similar efficacy.
However, lurasidone appears to have a better metabolic profile when compared with brexpiprazole. Also, notable benefits for lurasidone on total cholesterol, weight gain, and low-density lipoprotein were observed.
