Antipsychotics, also known as neuroleptics, are a class of medications primarily used to manage psychosis, including delusions, hallucinations, paranoia, or disordered thought, primarily in schizophrenia and bipolar disorder. They are believed to work by affecting the brain’s neurotransmitter systems, particularly by blocking the activity of dopamine. The introduction of antipsychotic drugs in the 1950s has significantly improved the prognosis of those living with these severe mental health conditions, allowing many to lead more stable and fulfilling lives.

There are two main types of antipsychotics: typical (first-generation) and atypical (second-generation). Typical antipsychotics, such as haloperidol, primarily work by blocking dopamine receptors and can be very effective in treating the positive symptoms of psychosis, such as hallucinations and delusions. However, they are associated with a high risk of side effects, including movement disorders like tardive dyskinesia. Atypical antipsychotics, such as risperidone and quetiapine, target a broader range of neurotransmitter receptors, including serotonin receptors, and are associated with a lower risk of movement disorders, but they can have other serious side effects, including weight gain and an increased risk of diabetes.

Despite their effectiveness, antipsychotic medications can have significant side effects, and their use needs to be carefully monitored. Long-term use of antipsychotics can lead to metabolic changes, cardiovascular issues, and an increased risk of mortality in elderly patients with dementia-related psychosis. It is crucial for patients on these medications to have regular check-ups with their healthcare provider to monitor for potential side effects and to ensure that the medication is still necessary and effective.

Some of the generic drugs in the antipsychotic category include haloperidol, risperidone, quetiapine, olanzapine, and aripiprazole. Each of these drugs has a unique profile in terms of its effectiveness, side effects, and the conditions it is used to treat. For example, risperidone and quetiapine are often used in the treatment of schizophrenia and bipolar disorder, while aripiprazole may be used as an adjunct treatment for major depressive disorder. The choice of which antipsychotic to use will depend on the individual patient’s symptoms, medical history, and the drug’s side effect profile.
