What is the main therapeutic effect of antipsychotic medications?

The main therapeutic effect of antipsychotic medications is the management of psychotic disorders. These medications are specifically designed to treat conditions such as schizophrenia, bipolar disorder, and severe depression when psychotic features are present. They work primarily by affecting neurotransmitters in the brain, particularly dopamine and serotonin, which can help alleviate symptoms such as hallucinations, delusions, and disorganized thinking.

The other options relate to treatments for different health issues. For example, eliminating lice pertains to antiparasitic medications, while fighting fungal infections is associated with antifungal agents. Facilitating bowel movements involves laxatives or other medications for gastrointestinal function. Each of these options addresses distinct medical conditions, but antipsychotic medications are uniquely focused on treating the complexities of psychotic disorders.
