Aripiprazole had less side- effects than olanzapine and risperidone (such as weight gain, sleepiness, heart problems, shaking and increased cholesterol levels). Aripiprazole was not as good as ziprasidone for dealing with restlessness or people's inability to sit still.
Clozapine and olanzapine have the safest therapeutic effect, while the side effect of neutropenia must be controlled by 3 weekly blood controls.
Other tolerability measures
On SUCRA analysis, lurasidone ranked the best tolerated option in terms of somnolence followed by cariprazine, aripiprazole, olanzapine, quetiapine and ziprasidone (Table 14).
Second generation or atypical antipsychotics are less likely to cause movement side effects, but you might still experience them. If you do, then your doctor might change your medication.
Haldol (haloperidol) and Thorazine (chlorpromazine) are the best known typical antipsychotics. They continue to be useful in the treatment of severe psychosis and behavioral problems when newer medications are ineffective.
Of the atypical antipsychotics, risperidone is the weakest in terms of atypicality criteria.
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.
Amongst the many adverse effects of the first generation, or 'typical' antipsychotics, the most disturbing was Tardive Dyskinesia, which involves uncontrollable movements of face, hands and feet [2].
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.
Clinician choice of an atypical antipsychotic may depend on a number of factors such as perceived efficacy, tolerability and cost. It is also important that the choice of treatment takes into consideration the previous response to treatment, experience of side-effects and personal clinical characteristics.
In particular, antipsychotic drugs have been linked to an increased risk of falls, diabetes and heart disease. Older adults are also more likely to be prescribed multiple medications, increasing the likelihood of negative drug interactions.
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.
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.
Drugs with the fastest onsets include haloperidol, risperidone, and olanzapine, with onsets appearing in 2 6 days.
Seroquel has an average rating of 7.0 out of 10 from a total of 646 ratings on Drugs.com. 60% of reviewers reported a positive effect, while 21% reported a negative effect. Zyprexa has an average rating of 5.8 out of 10 from a total of 390 ratings on Drugs.com.
Seroquel is an antipsychotic that helps to calm and relieve psychotic thoughts. It is often given because it is quite sedating; however, care is needed because it also lowers blood pressure.
Olanzapine has an average rating of 5.8 out of 10 from a total of 985 ratings on Drugs.com. 45% of reviewers reported a positive effect, while 34% reported a negative effect. Quetiapine has an average rating of 7.2 out of 10 from a total of 2076 ratings on Drugs.com.
If an antipsychotic is providing substantial benefit, and the adverse effect is not life‐threatening, then the first management choice is to lower the dose or adjust the dosing schedule. The next option is to change the antipsychotic; this is often reasonable unless the risk of relapse is high.
Evidence of the rapidity at which antipsychotics can affect brain volume in humans was recently provided by Tost and associates. These investigators found a significant, reversible decrease in striatal volume in healthy subjects within 2 hours after they were treated intravenously with haloperidol.
Consensus guidelines typically recommend continued antipsychotic medication for 1–2 years, although it has been suggested that treatment discontinuation in the form of targeted intermittent treatment (dose reduction, antipsychotic discontinuation if feasible, and immediate reintroduction if symptoms reemerge) should ...
Recent research has found that long-acting injectables (LAIs) may be better than oral medications at reducing the risk of hospitalization from schizophrenia. They also can be taken less frequently than oral medications, which often need to be taken every day.
Conclusions. Viewed together with data from animal studies, our study suggests that antipsychotics have a subtle but measurable influence on brain tissue loss over time, suggesting the importance of careful risk-benefit review of dosage and duration of treatment as well as their off-label use.
