AB Aripiprazole and risperidone are 2 of the most used second-generation antipsychotics (SGAs) worldwide. Previous evidence shows a similar effect of these SGAs on weight and metabolic changes in the short term. However, a longer period is necessary for a better assessment of the SGA´s metabolic profile. We aimed to compare the long-term (1-year) metabolic profile of these 2 antipsychotics on a sample of drug-naïve first episode-psychosis (FEP) patients. A total 188 drug-naïve patients, suffering from a first episode of non-affective psychosis (FEP), were randomly assigned to treatment with either aripiprazole or risperidone. Weight and glycemic/lipid parameters were recorded at baseline and after 1-year follow-up. We observed significant weight increments in both groups (9.2 kg for aripiprazole and 10.5 kg for risperidone) after 1 year of treatment. Despite this, weight and body mass index changes did not significantly differ between treatment groups (P > .05). Similarly, both treatment groups presented similar metabolic clinical impact with a comparable increase in the proportion of participants meeting criteria for metabolic disorders such as obesity or hypercholesterolemia, but not for metabolic syndrome (Δ9.2% vs Δ4.3%) or hypertriglyceridemia (Δ21.9% vs Δ8.0%), where aripiprazole showed worse outcomes than risperidone. This study shows that aripiprazole and risperidone share a similar long-term metabolic profile. After 1 year of antipsychotic treatment, drug-naïve FEP patients in both treatment groups presented a significant increase in weight and metabolic changes, leading to a greater prevalence of metabolic disorders.
