Neuroleptic drugs, also known as antipsychotics, are medications used to manage psychiatric conditions such as schizophrenia, bipolar disorder, and severe agitation. They work primarily by blocking dopamine receptors in the brain, which helps reduce symptoms like hallucinations, delusions, and disorganized thinking. Neuroleptics are broadly classified into typical (first-generation) and atypical (second-generation) antipsychotics, with newer agents generally having fewer movement-related side effects.
