How effective is haloperidol for schizophrenia?
Despite over 30 years of trials, data on the effects of differing doses of haloperidol are sparse and poorly reported. This is especially so for the lower dose ranges generally used for the treatment of schizophrenia today. However, lower doses of haloperidol may be just as effective as higher doses but result in fewer side effects.
How do we select studies for clinical trials of haloperidol?
We selected studies if they involved people being treated for acute schizophrenia, randomised to two or more dose ranges of non-depot haloperidol, and if they reported clinically meaningful outcomes. For this update, we inspected all citations and independently re-inspected a sample of citations in order to ensure reliable selection.
Which medications are used in the treatment of schizophrenia?

What is the best treatment for regressed schizophrenia?
History: chronic, regressed schizophrenia, had received prolonged courses of ECT, insulin, and "total push" programs, without lasting benefit. Combination therapy: reserpine + chlorpromazine (N = 10). Monotherapy: reserpine (N = 10). Monotherapy: chlorpromazine (N = 10).
What are the two main antipsychotic drugs for schizophrenia?
Antipsychotics are sometimes also called major tranquillisers. There are two main types of antipsychotics: Newer or atypical antipsychotics. These are sometimes called second-generation antipsychotics and include: amisulpride, aripiprazole, clozapine, olanzapine, quetiapine and risperidone.
Is prolixin the same as Haldol?
Prolixin (fluphenazine) Haldol (haloperidol) is less likely to cause weight gain and sedation, but more likely to cause movement disorders compared to other antipsychotics. Treats schizophrenia and psychosis. Prolixin (fluphenazine) can stabilize your mood.

What is the front line treatment for schizophrenia?
Antipsychotic medications are the first-line medication treatment for schizophrenia. They have been shown in clinical trials to be effective in treating symptoms and behaviors associated with the disorder.
What is the strongest anti psychotic drug?
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.
Why was prolixin discontinued?
Fluphenazine decanoate is a first generation antipsychotic. It is also known by the trade name Modecate. The manufacturer discontinued the drug due to a shortage of ingredients, but it is still licensed for use.
What treatment is most effective for schizophrenia?
Antipsychotics. Antipsychotics are usually recommended as the initial treatment for the symptoms of an acute schizophrenic episode. They work by blocking the effect of the chemical dopamine on the brain.
What is the most effective therapy for schizophrenia?
The most common types of therapy for schizophrenia include: Cognitive behavior therapy (CBT). This treatment helps you change how you think and react to things. It also teaches you to deal with negative feelings by thinking about them in a different way so you feel good instead.
What is the main drug used to treat schizophrenia?
Haloperidol, fluphenazine, and chlorpromazine are known as conventional, or typical, antipsychotics and have been used to treat schizophrenia for years. However, they sometimes have movement-related side effects, such as tremors and dystonia, a condition that causes involuntary muscle contractions.
When should a schizophrenic go to the hospital?
You may have to go to the hospital if: You're having a psychotic episode. This means that you can't tell the difference between what is real and what isn't real. You talk about suicide or hurting yourself or others.
What is the best medication for schizoaffective disorder?
The only medication approved by the Food and Drug Administration specifically for the treatment of schizoaffective disorder is the antipsychotic drug paliperidone (Invega). However, doctors may prescribe other antipsychotic drugs to help manage psychotic symptoms such as delusions and hallucinations.
What is the most common type of delusion in schizophrenia?
A common schizophrenia delusion type is the paranoid delusion. Another word for these are persecutory delusions. These are delusions where a person believes they are being harassed, harmed, or otherwise watched by others.
How do second generation antipsychotics work?
Some second-generation antipsychotics actually work by increasing dopamine signaling in certain parts of the brain. Examples of these include:
What is the difference between first and second generation antipsychotics?
Both first- and second-generation antipsychotic medications can effectively reduce psychotic symptoms associated with schizophrenia and improve overall quality of life. Second-generation antipsychotics are associated with a lower risk of neurological symptoms, such as tremors, than first-generation drugs.
What are the two types of antipsychotics?
There are two types of antipsychotic therapy: first-generation antipsychotics and second-generation antipsychotics. MNT spoke with experts in the field to understand the differences and similarities between antipsychotic therapies. Here is what people with schizophrenia should know about their treatment options.
How do antipsychotics work?
Experts believe that antipsychotic medications work at least in part by disrupting dopamine signaling, which is elevated in certain parts of the brain in people with schizophrenia. Both first-generation and second-generation antipsychotics improve the “positive” symptoms of schizophrenia, which include hallucinations and delusions.
Why do doctors prescribe antipsychotics?
Doctors prescribe antipsychotic medications to prevent the psychotic symptoms associated with schizophrenia. People can use them for immediate relief as well as for long-term maintenance (to prevent or reduce the severity of future episodes of psychosis).
What is the first generation of antipsychotics?
First-generation antipsychotics are older medications that block dopamine receptors in the brain to prevent signaling. Some examples of first-generation antipsychotics include:
What should a person's choice of antipsychotics be based on?
Experts told MNT that a person’s choice of antipsychotic should be based on a discussion with a doctor about their goals, disease history, and concerns. Choosing the right medication should be a balance of controlling the symptoms without experiencing problematic side effects.
How many patients report favorable treatment outcomes for schizophrenia?
The prognosis for patients with schizophrenia is generally unpredictable.2Only 20% of patients report favorable treatment outcomes.12The remaining patients experience numerous psychotic episodes, chronic symptoms, and a poor response to antipsychotics.2
How to diagnose schizophrenia?
A diagnosis of schizophrenia is reached through an assessment of patient-specific signs and symptoms, as described in the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition (DSM-5).12The DSM-5states that “the diagnostic criteria [for schizophrenia] include the persistence of two or more of the following active-phase symptoms, each lasting for a significant portion of at least a one-month period: delusions, hallucinations, disorganized speech, grossly disorganized or catatonic behavior, and negative symptoms.”12At least one of the qualifying symptoms must be delusions, hallucinations, or disorganized speech.12
What are the side effects of schizophrenia?
Schizophrenia medications can cause a variety of other adverse effects, including the following: 1 Antipsychotic medications with anticholinergic effects have been shown to worsen narrow-angle glaucoma, and patients should be appropriately monitored.49Chlorpromazine is most commonly associated with opaque deposits in the cornea and lens.2Because of the risk of cataracts, eye examinations are recommended for patients treated with quetiapine.50Those using thioridazine at doses exceeding 800 mg daily are at risk of developing retinitis pigmentosa.2 2 Low-potency FGAs and clozapine have been associated with urinary hesitancy and retention.2The incidence of urinary incontinence among patients taking clozapine can be as high as 44% and can be persistent in 25% of patients.2,51 3 FGAs and risperidone have a greater tendency to cause sexual dysfunction compared with SGAs.2,52 4 Treatment with antipsychotics can cause transient leukopenia.2,53 5 The three antipsychotics with the greatest risk for hematological complications are clozapine, chlorpromazine, and olanzapine.54Clozapine is associated with an especially high risk for the development of neutropenia or agranulocytosis.54 6 On rare occasions, dermatological allergic reactions have occurred at approximately eight weeks after the initiation of antipsychotic therapy.2 7 Both FGAs and SGAS can cause photosensitivity, leading to severe sunburn.2 8 Clozapine has been reported to cause sialorrhea in approximately 54% of patients with schizophrenia.2The mechanism of this effect is unknown.2
How many nonadherence rates are there in schizophrenia?
Not only do nonpharmacological therapies fill in gaps in pharmacological treatments; they can help to ensure that patients remain adherent to their medications.18Nonadherence rates in schizophrenia range from 37% to 74%, depending on the report.19Individuals with mental disorders tend to be less adherent for several reasons. They may deny their illness; they may experience adverse effects that dissuade them from taking more medication; they may not perceive their need for medication; or they may have grandiose symptoms or paranoia.2
What are the factors that contribute to schizophrenia?
Environmental and social factors may also play a role in the development of schizophrenia, especially in individuals who are vulnerable to the disorder.1Environmental stressors linked to schizophrenia include childhood trauma, minority ethnicity, residence in an urban area, and social isolation.1In addition, social stressors, such as discrimination or economic adversity, may predispose individuals toward delusional or paranoid thinking.1
What neurotransmitter is involved in schizophrenia?
Another theory for the symptoms of schizophrenia involves the activity of glutamate, the major excitatory neurotransmitter in the brain. This theory arose in response to the finding that phenylciclidine and ketamine, two noncompetitive NMDA/glutamate antagonists, induce schizophrenia-like symptoms.6This, in turn, suggested that NMDA receptors are inactive in the normal regulation of mesocortical dopamine neurons, and pointed to a possible explanation for why patients with schizophrenia exhibit negative, affective, and cognitive symptoms.7
What is the serotonin hypothesis?
The serotonin hypothesis for the development of schizophrenia emerged as a result of the discovery that lysergic acid diethylamide (LSD) enhanced the effects of serotonin in the brain. 1Subsequent research led to the development of drug compounds that blocked both dopamine and serotonin receptors, in contrast to older medications, which affected only dopamine receptors. The newer compounds were found to be effective in alleviating both the positive and negative symptoms of schizophrenia.1
Abstract
Many people with schizophrenia do not achieve a satisfactory treatment response with their initial antipsychotic drug treatment. Sometimes a second antipsychotic, in combination with the first, is used in these situations.
Plain language summary
Antipsychotic medication was introduced in the 1950s to reduce or alleviate the symptoms of schizophrenia, such as the psychotic states of hearing voices, visual hallucinations and strange thoughts such as paranoia (feeling singled‐out or put upon by others).
Background
Schizophrenia is a chronic disorder with a lifetime prevalence of four per 1000 persons ( McGrath 2008 ). It is characterised by emotional, cognitive, and behavioural dysfunctions.

What is the best treatment for schizophrenia?
Schizophrenia is a mental illness where the person often experiences both positive symptoms (such as hearing voices, seeing things and having strange beliefs) and negative symptoms (such as tiredness, apathy and loss of emotion). Antipsychotic drugs are used to treat schizophrenia. The antipsychotic drug, haloperidol, is one of the most frequently used drugs worldwide for people with schizophrenia.
What is haloperidol used for?
Haloperidol is a benchmark, accessible antipsychotic drug against which the effects of newer treatments are gauged. Objectives: To determine the best range of doses for haloperidol for the treatment of people acutely ill with schizophrenia. Search strategy:
Is haloperidol safe for schizophrenia?
It is, therefore, important to find a tolerable and effective dose of haloperidol, which helps control the symptoms of schizophrenia but with few er side effects. The main aim of this review was to determine the best range of doses of haloperidol for the treatment of schizophrenia . Nineteen trials were included that compared varying doses ...
Does haloperidol cause weight gain?
The benefits of antipsychotic drugs, such as haloperidol, need to be weighed against their tendency for causing debilitating side effects (such as movement disorders, weight gain, lack of drive) and in some cases an increased likelihood of physical illnesses such as diabetes and heart disease. These debilitating side effects may mean that people stop taking their medication, which can lead to relapse and going into hospital. It is, therefore, important to find a tolerable and effective dose of haloperidol, which helps control the symptoms of schizophrenia but with fewer side effects.
Is haloperidol a lower dose?
However, lower doses of haloperidol may be just as effective as higher doses but result in fewer side effects. This review also suggests that an important bias against haloperidol may exist in modern trials comparing new drugs with haloperidol.
What is the treatment for schizophrenia?

Does depot risperidone have a longer stay?
Patients initiated on depot risperidone had a longer length of stay prior to their first injection and were less likely to be discharged on that medication compared to patients initiated on depot fluphenazine or haloperidol, possibly indicating that patients initiating depot risperidone had a more s …
What is the treatment for schizophrenia?
Antipsychotics in the treatment of schizophrenia: an overview. Schizophrenia is characterized by positive, negative, cognitive, disorganization, and mood symptoms. Antipsychotics are the mainstay in the pharmacologic treatment of schizophrenia.
What should be the determinant of antipsychotic choice?
Choice of antipsychotic medication should be based on individual preference, prior treatment response and side effect experience, medical history and risk factors, and adherence history, with side effect profile a major determinant of antipsychotic choice.
What is schizophrenia characterized by?
Schizophrenia is characterized by positive, negative, cognitive, disorganization, and mood symptoms. Antipsychotics are the mainstay in the pharmacologic treatment of schizophrenia.
Can antipsychotics be used without EPS?
Thus, the ability of antipsychotics to produce a potent antipsychotic effect without EPS and need for concomitant anticholinergic therapy yields multiple therapeutic benefits. In contrast to their broadly similar efficacy, antipsychotics differ markedly in their propensity to cause various adverse effects.
Abstract
Objective: This study compares 3 cohorts of patients with schizophrenia before, during, and after initiating treatment with fluphenazine decanoate (FD), haloperidol decanoate (HD), or long-acting injectable risperidone (LAR).
Methods
Statewide service use and pharmacy claims from the California Medicaid (Medi-Cal) program were analyzed to assess characteristics of patients with schizophrenia who were initiating long-acting antipsychotic injections. The samples were drawn from 4 consecutive years of Medi-Cal data (2001–2004).
Results
A majority of patients were started on HD (60.5%), with fewer patients started on FD (35.2%) or LAR (4.3%). LAR became available to Medi-Cal recipients in December 2003.
Discussion
The current findings suggest that early discontinuation of depot antipsychotic medication is quite common in the community treatment of schizophrenia. After 180 days, only 9.7% of HD patients, 5.4% of FD patients, and 2.6% of LAR patients were continuing to receive the same long-acting antipsychotic medication.
