Although a large body of randomized controlled studies (RCTs) has shown that antipsychotics are highly effective in reducing symptoms and improving quality of life during short‐term interventions, it has been suspected that the use of antipsychotics in long‐term treatment may lead to brain atrophy 1 or a lower rate of …

Atypical antipsychotics seem to be preferable than conventional agents in treating psychological symptoms of dementia (BPSD), because they have substantially lower risks of extrapyramidal neurological effects with lower reported rates of parkinsonism and tardive dyskinesia.

This is because it has been demonstrated that atypical antipsychotic drugs are more effective across a broader range of symptoms of schizophrenia than typical antipsychotic drugs and because they are dramatically less likely to cause the extrapyramidal and endocrine side effects that greatly impair quality of life for …

Amisulpride was more effective than haloperidol and, if ziprasidone remains unlicensed, represents the most cost-effective atypical antipsychotic drug.

A person usually begins to feel some improvement within six weeks of starting to take antipsychotic medication. However, it can take several months before they feel the full benefits.

Side effects of antipsychotics can include the following:

• Stiffness and shakiness.
• Uncomfortable restlessness (akathisia).
• Movements of the jaw, lips and tongue (tardive dyskinesia).
• Sexual problems due to hormonal changes.
• Sleepiness and slowness.
• Weight gain.
• A higher risk of getting diabetes.
• Constipation.

Antipsychotic medications can help to calm and clear confusion in a person with acute psychosis within hours or days, but they can take up to four or six weeks to reach their full effect.

In the long-term, research shows that neuroleptics (antipsychotics) cause more harm than good for many clients diagnosed with schizophrenia. Their side-effect profiles and adverse event profiles are significant, and are dose and duration contingent.

Some studies also raise the possibility that antipsychotic medication can cause structural changes in certain brain regions, leading some to raise the alarm about “brain damage” from these drugs.

The classic cardiovascular effects that occur after overdose include tachycardia, hypotension and QT prolongation on ECG. One of the more serious clinical syndromes that can be seen with antipsychotic use and overdose is neuroleptic malignant syndrome.

First-generation antipsychotics In addition to producing adverse motor system effects, D2 blockade can have adverse effects on higher level cognitive skills. Such adverse effects on working memory are well established in animal models [12–14].

Even prior to the longitudinal period, a major review by Leucht, Davis, and colleagues has raised questions about long-term efficacy, noting “The meta-regression suggested that antipsychotic drugs might lose their effectiveness with time.”16 Other longitudinal studies could suggest that, long-term, schizophrenia …

No specific antidotes exist for the adverse effects of neuroleptic medications. Because these effects are so diverse and do not occur in most cases, prophylactic treatment for seizures, dystonia, dysrhythmias, or neuroleptic malignant syndrome (NMS) is not indicated.

Here are some coping skills that may help with side effects:

1. Get on to the right medication for you.
2. Change the dose of the antipsychotic medication.
3. Keep on taking the medication.
4. Treat the side effects of the antipsychotic.
5. Find out as much as you can about your schizophrenia.
6. Join a support group.

The new terminology calls them first-generation antipsychotics, these include drugs such as chlorpromazine, haloperidol, fluphenazine, among others.

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.

There are two main types of antipsychotics: atypical antipsychotics and older antipsychotics. Both types are thought to work as well as each other. Side-effects are common with antipsychotics.

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.

Generally speaking, antipsychotic medications work by blocking a specific subtype of the dopamine receptor, referred to as the D2 receptor. Older antipsychotics, known as conventional antipsychotics, block the D2 receptor and improve positive symptoms.
