Effects of gaps in doses between oral and long-acting injectable aripiprazole on clinical outcomes in schizophrenia

Schizophrenia is a serious mental health condition that affects how a person thinks, feels, and behaves. People with schizophrenia may experience symptoms like hearing things that are not there (hallucinations), having false beliefs (delusions), or having trouble thinking clearly. They may also have negative symptoms, like showing less emotion or lacking motivation.

The main treatment for schizophrenia is medication called antipsychotics. These medications help improve the symptoms and prevent them from coming back, which is why people with schizophrenia need to take them regularly, even when they feel better.

However, these medications can cause side effects, such as involuntary movements and issues with metabolism (how the body uses food for energy) and the heart. These side effects can make it harder for people to stick to their treatment, which can be tough on both the patients and their families or caregivers.

Some side effects are linked to the amount of medication a person takes. For this reason, doctors try to use the smallest effective dose to minimize risks. Past studies have shown that lowering the dose of antipsychotics can help reduce side effects without causing the symptoms to come back in people who are stable. However, there haven't been any studies that focus on reducing the dose of aripiprazole, a specific antipsychotic, and how this affects people with schizophrenia.

We believe that by looking at studies where patients switched from taking oral aripiprazole (the pill form) to long-acting injectable aripiprazole (a shot given every few weeks), we can learn more about how changing doses might impact people’s symptoms. Since the shot is typically given in a fixed amount (either 400 mg every month or 300 mg if needed), some people may receive more or less medication than before when they switch from the pill.

To understand this better, we will analyze the data from these studies and look at how the change in dose affects symptoms and side effects.

If our analysis shows that reducing the dose of aripiprazole does not worsen symptoms and helps reduce side effects, it could make treatment easier for people with schizophrenia, lower the burden on their families, and even help reduce healthcare costs.
