It effectively targets both the positive symptoms, such as delusions and hallucinations, and has some impact on negative symptoms as well. Risperidone acts as an antagonist to serotonin and dopamine receptors, which are believed to play a significant role in the pathophysiology of schizophrenia.

Clinical guidelines favor risperidone due to its balanced effectiveness relative to the potential risks of metabolic side effects associated with some atypical antipsychotics. Although other agents in the same class can also be effective, risperidone's profile makes it a preferred option, especially in initial treatment settings.

While options like quetiapine, olanzapine, and clozapine are also utilized in the treatment of schizophrenia, they may not always be the first choice due to varying degrees of side effects or specific indications. For example, clozapine is typically reserved for treatment-resistant cases due to its unique risk profile, including agranulocytosis, requiring careful monitoring. Quetiapine and olanzapine, while effective, also have a greater propensity for metabolic side effects, making them less favorable
