Final answer:
Antipsychotic drugs are primarily used to manage psychotic disorders like schizophrenia, working by blocking dopamine receptors. These drugs have a gradual effect, starting within two to seven days, and help reduce psychotic symptoms in approximately 70% of patients.
Step-by-step explanation:
Antipsychotic drugs are typically used to treat patients with psychotic disorders such as schizophrenia or those in a psychotic state. This helps alleviate symptoms such as hallucinations, delusions, and disorganized thinking. While effectiveness varies, antipsychotics reduce symptoms in about 70% of patients. It's important to note that these drugs work gradually, with patients beginning to see improvement within two to seven days of starting treatment.
Additionally, for those with bipolar disorder, antipsychotics can be used in conjunction with mood stabilizers to help manage manic episodes. Other benefits of these drugs include antiemetic (preventing vomiting) and antihistaminic effects. However, long-term usage is often necessary as they are not a cure for psychiatric illnesses.
