What antipsychotics cause neuroleptic malignant syndrome?

The primary trigger of NMS is dopamine receptor blockade and the standard causative agent is an antipsychotic. Potent typical neuroleptics such as haloperidol, fluphenazine, chlorpromazine, trifluoperazine, and prochlorperazine have been most frequently associated with NMS and thought to confer the greatest risk.

Which antipsychotics cause NMS?

Atypical antipsychotic drugs that may cause NMS include the following:

  • Olanzapine.
  • Risperidone.
  • Paliperidone.
  • Aripiprazole.
  • Ziprasidone.
  • Amisulpride.
  • Quetiapine.

Do typical antipsychotics cause neuroleptic malignant syndrome?

All antipsychotic drugs can cause NMS. The older antipsychotic drugs include: Chlorpromazine (Thorazine) Fluphenazine (Prolixin)

Which medication poses the greatest risk for neuroleptic malignant syndrome?

Regarding the type of antipsychotic drug, typical (or “first generation”) antipsychotics are associated with a higher risk for development of NMS compared to atypical or “second generation”, antipsychotics.

Can olanzapine cause neuroleptic malignant syndrome?

Neuroleptic malignant syndrome can occur with atypical antipsychotic drugs such as olanzapine, particularly when risk factors are present. We should pay attention to this rare but life-threatening event associated with fatal complications.

Which atypical antipsychotic drug has the lowest hypotensive effects?

Quetiapine and risperidone appear to have the lowest risk of hypertension.

What is the treatment for neuroleptic malignant syndrome?

Medications prescribed as treatment may include skeletal muscle relaxants, such as dantrolene; stimulators of dopamine production and activity, such as bromocriptine; and/or continuous perfusion of central nervous system depressants, such as diazepam.

How do you test for neuroleptic malignant syndrome?

No laboratory test result is diagnostic for neuroleptic malignant syndrome (NMS).

Approach Considerations

  1. Complete blood count (CBC)
  2. Blood cultures.
  3. Liver function tests (LFTs)
  4. Blood urea nitrogen (BUN) and creatinine levels.
  5. Calcium and phosphate levels.
  6. Creatine kinase (CK) level.
  7. Serum iron level.
  8. Urine myoglobin level.

Are neuroleptics and antipsychotics the same thing?

Neuroleptics, also known as antipsychotic medications, are used to treat and manage symptoms of many psychiatric disorders. They fall into two classes: first-generation or “typical” antipsychotics, and second-generation or “atypical” antipsychotics.

What is NMS syndrome?

INTRODUCTION Neuroleptic malignant syndrome (NMS) is a life-threatening neurologic emergency associated with the use of antipsychotic (neuroleptic) agents and characterized by a distinctive clinical syndrome of mental status change, rigidity, fever, and dysautonomia.

What is the difference between NMS and serotonin syndrome?

NMS and serotonin syndrome are rare, but potentially life-threatening, medicine-induced disorders. Features of these syndromes may overlap making diagnosis difficult. However, NMS is characterised by ‘lead-pipe’ rigidity, whilst serotonin syndrome is characterised by hyperreflexia and clonus.

Can serotonin cause heart failure?

Tachyarrhythmia and hyperthermia due to serotonin syndrome, in addition to takotsubo cardiomyopathy, can deteriorate to congestive heart failure following a rapid ventricular response of preexisting atrial fibrillation.
