Long-Acting Injectable Antipsychotics: Ensuring Consistent Mental Health Care
Long-Acting Injectable Antipsychotics (LAIs) deliver sustained medication through periodic injections, ensuring stable symptom control. Ideal for adherence challenges, LAIs reduce relapses, improve outcomes, and lower hospitalization risk.
What Are Long Acting Injectables?
Long-Acting Injectable Antipsychotics (LAI’s) are a special kind of antipsychotic medicine. They’re designed to give you a steady dose of medicine for a long time, without you having to take it every day. Instead of taking pills, you’ll get an injection every few weeks or months, depending on the medicine you’re taking
How are they given?
How Do LAI’s Work?
The medicine in LAI’s is wrapped in a special slow-release system. When you get the injection, the medicine starts to release into your bloodstream slowly over time. This means you’ll have a steady level of medicine in your body, and you won’t have the ups and downs that you might get with daily pills
Which Patients Can Benefit
Poor Adherence History
If you've had multiple episodes of psychotic or mood disturbances due to missed medications, long-acting injectables (LAIs) might be an excellent choice.
Frequent Relapses
If you’ve had a lot of episodes of psychotic or mood disturbances because you didn’t take your medicine, LAIs might be a good choice.
Severity of Symptoms
If severe symptoms make it difficult to take daily medication consistently, long-acting injectables (LAIs) could be a more effective option for you.
Cognitive Impairment
If you have trouble remembering to take your medicine because of your thinking skills, LAI's might be a better option.
Patient Preference
Some individuals may prefer the convenience of receiving an injection every few weeks rather than remembering to take daily tablets regularly.
Lack of Insight
If you have limited insight into your condition or struggle to understand why medication is necessary, long-acting injectables (LAIs) may be beneficial.
Long-Acting Antipsychotics (LAIs) reduce hallucinations and delusions while stabilizing mood and behavior in schizophrenia.
LAIs demonstrate high efficacy in preventing relapses and reducing hospitalizations.
LAIs are instrumental in managing manic episodes and mitigating mood swings in bipolar disorder.
They contribute to maintaining a stable mood for an extended period and reducing the frequency of mood episodes, leading to improved overall functioning.
LAIs provide comprehensive treatment for both psychotic and mood-related symptoms in schizoaffective disorder.
By facilitating improved functioning and reducing the frequency of episodes, LAIs contribute to a more manageable condition.

- Repeat Hospitalization Reduction: Effective in reducing hospitalization rates
| Condition | Schizophrenia | Bipolar Disorder | Schizoaffective Disorder |
|---|---|---|---|
| Number of Studies/Participants | 42 studies, 101,624 participants | Limited direct studies, but suggests efficacy | Fewer studies, data from schizophrenia studies |
| Baseline Characteristics | Severe symptoms, chronic illness history, high non-adherence | Manic and depressive episodes, non-adherence risk | Mood and psychotic symptoms overlap |
| LAI Types and Dosage | First-gen (fluphenazine), second-gen (risperidone, paliperidone) | Limited data, aripiprazole LAI promising | Varies, often aligns with schizophrenia regimens |
| Duration | Min 24 weeks, some >18 months | Varied, often shorter trials | Long-term studies limited |
| Effectiveness Outcomes | Lower relapse rates, improved adherence, fewer hospitalizations | Stabilized mood, reduced relapses | Improved mood and psychotic symptoms, reduced hospitalizations |
| Impact on Burden of Illness | Reduced admissions, better long-term outcomes | Improved quality of life, fewer severe episodes | Better symptom control, lower caregiver burden |
| Cost Reduction | Lower hospitalization and crisis costs | Potential cost benefits | Anticipated cost savings |
| Repeat Hospitalization Reduction | Significant reduction | Reduced manic/depressive admissions | Moderate evidence, more research needed |
| Antipsychotic Equivalency | Not uniformly reported | Aripiprazole-based studies show some equivalency | Varies by medication |
