This document discusses neuroleptic drugs, which are used to treat mental illnesses like schizophrenia. Neuroleptics, also called antipsychotics, can be classified into different categories including phenothiazines, butyrophenones, and thioxanthenes. They work by blocking dopamine receptors in the brain. Neuroleptics are generally safe when used as prescribed but can cause side effects. Their benefits include improving mood and thought processes, while risks include producing side effects that mimic neurological diseases. Treatment involves using typical or atypical antipsychotics depending on the symptoms.
