Abilify Maintena (aripiprazole) is a long-acting injectable (LAI) formulation of aripiprazole. It is the first of two formulations of LAI aripiprazole (the other is Aristada [aripiprazole lauroxil]). It is FDA-indicated to treat adults with schizophrenia and bipolar disorder.
- Once every four-week intramuscular injection only, which must be administered by a healthcare provider.
- No loading dose strategy is available. Two weeks of oral overlap (at therapeutic range) recommended at the time of administration of first injection. Oral aripiprazole (10-20 mg/d) or another antipsychotic must be continued for the first 14 days following the initial aripiprazole LAI.
- Recommended starting and maintenance dose is 400 mg (or lower dose of 300mg for patients who have had adverse reactions) administered once monthly (no sooner than 26 days after the previous injection). Provides maximum plasma concentration in 4–7 days, dependent on injection location, with deltoid injections achieving this sooner.
- Steady-state concentrations achieved by the 300- and 400-mg LAI formulations were within apparent therapeutic range observed with oral aripiprazole doses of 10 and 20 mg. Steady-state concentrations achieved with the 200-mg LAI formulation were found to be below the apparent therapeutic range observed with 10-mg oral daily dosing.

Practical issues (including administration)
- Abilify Maintena comes in two forms:
- Single dose prefilled dual chamber syringe kits for 300 mg and 400 mg doses – fewer steps and components. This formulation should be utilized within 30 minutes of reconstitution.
- Single dose vial kit – more dosing flexibility to administer lower doses: 160 mg, 200 mg, 300 mg, or the standard (recommended starting and maintenance) dose of 400 mg.
- All doses and formulations of Abilify Maintena can be administered intramuscularly in the deltoid or gluteal muscle.
