What should clinicians know about Aristada Initio (aripiprazole lauroxil LAI)?

Aristada Initio (aripiprazole lauroxil) is a long-acting, one-time loading dose injectable (LAI) formulation of aripiprazole used to avoid the necessity of oral Abilify (aripiprazole). It is FDA-indicated to treat adults with schizophrenia when initiating Aristada (aripiprazole lauroxil).
