Long-acting injectable antipsychotics (LAIs) were developed in the sixties with the purpose of improving schizophrenia maintenance treatment. The main advantages are: the ability to ensure compliance, maintaining stable plasma concentrations and allowing better clinical management of drug therapy. Long-acting atypical injectable antipsychotics start to develop in the late nineties. Currently, they are the most widely used depot treatment for severe mental illness.

Checking patient profile and diagnosis where we use LAIs.

Review of 217 patients treated with LAIs in CSM El Coto–Gijón.

In our sample, the average age of the patients was 48.94 years old. Most of them were men (135 vs. 82). More than half of treated patients were diagnosed with schizophrenia (112), the paranoid subtype was the most repeated (93). Other severe mental illnesses were also treated with LAIs: emotionally unstable personality disorder (31), delusional disorder (19), bipolar disorder (15), schizoaffective disorder (12) and other less frequently. For all groups, paliperidone palmitate was the most used injectable antipsychotic. The new aripiprazole long-acting injectable starts being used in psychotic patients with a significant affective component.

The schizophrenic patient remains being the prime candidate for this therapy although other severe mental disorders may also benefit of LAIs treatment. Most classical long-acting injectable antipsychotics have been replaced by new atypical injectable antipsychotics with a more tolerable side effects profile.
