Clozapine, which has the strongest antipsychotic effect, can cause neutropenia. A problem in the treatment of schizophrenia is poor patient compliance leading to the recurrence of psychotic symptoms.
Butyrophenones. Butyrophenones also work by a mechanism of action that blocks dopamine and they have antipsychotic and antiemetic effects. Haldol is a butyrophenone and is the most widely used typical antipsychotic. It also is also considered high-potency for dopamine blockade.
The main study findings, from this population-wide head-to-head comparison of thirty-seven antipsychotics, is that zuclopenthixol showed the strongest association with sedation and somnolence while prochloperazine resulted in the weakest association.
Of the atypical antipsychotics, risperidone is the weakest in terms of atypicality criteria.
Drugs with the fastest onsets include haloperidol, risperidone, and olanzapine, with onsets appearing in 2 6 days.
What is a good replacement for Seroquel? Other atypical antipsychotics may be tried when Seroquel is not effective or has intolerable side effects. Those may include Risperdal, Rexulti, Zyprexa, or Latuda.
Examples of high potency antipsychotic medications are fluphenazine, trifluoperazine and haloperidol. They have a large side effect profile and can lead to extrapyramidal symptoms and neuroleptic malignant syndrome. Extrapyramidal symptoms observed with administration of these drugs can evolve over time.
Chlorpromazine was the first antipsychotic and was followed by a large number of other antipsychotics, many with diverse chemical structures. However, so far, no antipsychotic has been shown to be significantly more effective than chlorpromazine in treating schizophrenia with the notable exception of clozapine.
Atypical antipsychotics such as quetiapine, aripiprazole, olanzapine, and risperidone have been shown to be helpful in addressing a range of anxiety and depressive symptoms in individuals with schizophrenia and schizoaffective disorders, and have since been used in the treatment of a range of mood and anxiety disorders ...

If you have another psychotic episode, you may need to take antipsychotic medication for longer, up to 5 years.
Previous research has also shown that the use of antipsychotics may raise the risk of metabolic syndrome in patients with schizophrenia. Metabolic syndrome has, in turn, been associated with heart disease and diabetes.
Olanzapine is associated with a lower incidence of extrapyramidal symptoms than typical and some atypical antipsychotics,93,94 an important cause of noncompliance and treatment discontinuation.

Abilify, Haloperidol, Zyprexa, Seroquel, and Invega are some risperidone alternatives.
Clozapine is often the last resort for treatment-resistant schizophrenia.
Now, a United States-based biotech organisation called Karuna Therapeutics Inc. has developed a new combination drug called KarXT. It is the first potential new pharmacological approach for treating schizophrenia in over 50 years and may provide an alternative option for people living with the condition.
Antipsychotics are often recommended life-long for people diagnosed with schizophrenia or other serious mental illnesses because they are effective at controlling psychotic symptoms in the short term and might reduce the risk of relapse.
Generally, the use of two or more antipsychotic medications concurrently should be avoided except in cases of three failed trials of monotherapy, which included one failed trial of clozapine where possible, or where a second antipsychotic medication is added with a plan to cross-taper to monotherapy.
Some common ones are: Chlorpromazine (Thorazine) Fluphenazine (Prolixin) Haloperidol (Haldol)
