Clozapine, which has the strongest antipsychotic effect, can cause neutropenia.
Medications available in this class include risperidone (Risperdal), quetiapine (Seroquel), olanzapine (Zyprexa), ziprasidone (Zeldox), paliperidone (Invega), aripiprazole (Abilify) and clozapine (Clozaril).
Quetiapine abuse is relatively common, and is abused far more often than any other second-generation antipsychotic. Emergency physicians should be aware of the clinical effects that may occur after second-generation antipsychotic abuse.
In general, the high-milligram, low-potency antipsychotics, such as chlorpromazine and mesoridazine, produce more sedation than the low-milligram, high-potency antipsychotics such as haloperidol and fluphenazine (Table 1). This principle tends to hold true for the atypical antipsychotics as well.
The Expert Consensus Guideline39 suggested that clozapine and risperidone would be a good first line choice for chronic aggression, followed by olanzapine or long-acting injectable atypical antipsychotic or quetiapine, ziprasidone, aripiprazole, as well as long-acting conventional antipsychotics.
Drugs with the fastest onsets include haloperidol, risperidone, and olanzapine, with onsets appearing in 2 6 days. Chlorpromazine and thiothixene were at the slowest end of the continuum, with onsets of 2 weeks or longer.
Haloperidol is a medication used to treat schizophrenia, acute psychosis and delirium. This drug has many serious side effects and is very potent. It is a derivative of butyrophenone, which were the original antipsychotics, developed in the 1950s.
Of the atypical antipsychotics, risperidone is the weakest in terms of atypicality criteria.
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 ...
Fluphenazine (Prolixin): This drug treats schizophrenia and psychotic symptoms such as hallucinations, delusions, and hostility. Haloperidol (Haldol): Doctors prescribe this drug to treat psychotic disorders, tics associated with Tourette's syndrome, and severe behavioral problems in children.
Antipsychotics. Antipsychotic medicines are usually recommended as the first treatment for psychosis. They work by blocking the effect of dopamine, a chemical that transmits messages in the brain.
These antipsychotic drugs come in a long-lasting form: Aripiprazole (Abilify Maintena) Aripiprazole lauroxil (Aristada) Fluphenazine (Prolixin)
Antipsychotics were discovered in the late 1950s. This first antipsychotic drug, chlorpromazine, was first developed as a “tranquilizer.” Its usefulness for treating psychosis was recognized by accident.
Schizophrenia is one type of psychotic disorder. People with bipolar disorder may also have psychotic symptoms. Other problems that can cause psychosis include alcohol and some drugs, brain tumors, brain infections, and stroke. Treatment depends on the cause of the psychosis.

Psychosis can also be triggered by traumatic experiences, stress, or physical conditions, such as Parkinson's disease, a brain tumour, or as a result of drug misuse or alcohol misuse. How often a psychotic episode occurs and how long it lasts can depend on the underlying cause.
You'll typically need mood-stabilizing medication to control manic or hypomanic episodes. Examples of mood stabilizers include lithium (Lithobid), valproic acid (Depakene), divalproex sodium (Depakote), carbamazepine (Tegretol, Equetro, others) and lamotrigine (Lamictal).
Antipsychotic medications are generally used to treat the symptoms of schizophrenia and other psychotic disorders. But they can also be used to treat bipolar disorder and depression. This section explains more about antipsychotics. This information is for adults affected by mental illness in England.
heart palpitations, which are heartbeats that suddenly become more noticeable in your chest. effects on your heart rhythm. This has been known to cause sudden death in extreme cases. The risk of this is especially linked to being on a high dose, or taking more than one antipsychotic at the same time.
Seroquel (quetiapine) is known to act on numerous receptors in the brain but the exact way it works is unknown; however, some experts believe its mood-calming effects may be through the antagonism of dopamine and serotonin receptors.
Antipsychotic medications don't 'cure' psychosis, but they are often effective in reducing and controlling many symptoms, including: delusions and hallucinations, such as paranoia and hearing voices.
Paliperidone, iloperidone, asenapine, and lurasidone are the newest oral atypical antipsychotic medications to be introduced since the approval of aripiprazole in 2002.
While not a certainty, long‐term antipsychotic treatment is a very common outcome for people with schizophrenia.
Clozapine is the most effective antipsychotic in terms of managing treatment-resistant schizophrenia. This drug is approximately 30% effective in controlling schizophrenic episodes in treatment-resistant patients, compared with a 4% efficacy rate with the combination of chlorpromazine and benztropine.
Antipsychotics are commonly prescribed to help with symptoms such as hallucinations, delusions, or racing thoughts, but can also be prescribed for individuals without those symptoms. Some antipsychotics are considered mood stabilizers because they, too, even out the highs and lows.
