What are the extrapyramidal side effects of antipsychotic drugs?

Extrapyramidal side effects: Physical symptoms, including tremor, slurred speech, akathesia, dystonia, anxiety, distress, paranoia, and bradyphrenia, that are primarily associated with improper dosing of or unusual reactions to neuroleptic (antipsychotic) medications.

Extrapyramidal symptoms are most commonly caused by typical antipsychotic drugs that antagonize dopamine D2 receptors. The most common typical antipsychotics associated with EPS are haloperidol and fluphenazine.

Additionally, what is the most troublesome side effect of antipsychotic medications? 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.

Thereof, how do antipsychotics cause extrapyramidal side effects?

Antipsychotic medications commonly produce extrapyramidal symptoms as side effects. Extrapyramidal symptoms are caused by dopamine blockade or depletion in the basal ganglia; this lack of dopamine often mimics idiopathic pathologies of the extrapyramidal system.

What is the difference between tardive dyskinesia and extrapyramidal symptoms?

Tardive dyskinesia is a late-onset extrapyramidal symptom. It involves repetitive, involuntary facial movements, such as tongue twisting, chewing motions and lip smacking, cheek puffing, and grimacing. You might also experience changes in gait, jerky limb movements, or shrugging.

What are EPS side effects?

Medical Definition of Extrapyramidal side effects Extrapyramidal side effects: Physical symptoms, including tremor, slurred speech, akathesia, dystonia, anxiety, distress, paranoia, and bradyphrenia, that are primarily associated with improper dosing of or unusual reactions to neuroleptic (antipsychotic) medications.

What drugs cause dyskinesia?

Other drugs that can cause TD include: Metoclopramide (treats stomach problem called gastroparesis) Antidepressant drugs such as amitriptyline, fluoxetine, phenelzine, sertraline, trazodone. Antiparkinson drugs such as levodopa. Antiseizure drugs such as phenobarbital and phenytoin.

Are extrapyramidal side effects reversible?

Extrapyramidal Symptoms. EPS include acute dystonias, akathisia, Parkinsonism, and tardive dyskinesia (TD). EPS are serious, sometimes debilitating and stigmatizing adverse effects, and require additional pharmacotherapy. TD may persist after the discontinuation of treatment or even be irreversible.

How are extrapyramidal effects managed?

Management of acute extrapyramidal effects induced by antipsychotic drugs. Acute dystonias should be treated with anticholinergic medications or benzodiazepines. Antipsychotic-induced pseudoparkinsonism has the same clinical appearance as idiopathic parkinsonism. Symptoms generally appear within the first three months.

What is the difference between pyramidal and extrapyramidal tracts?

The pyramidal tracts (corticospinal tract and corticobulbar tracts) may directly innervate motor neurons of the spinal cord or brainstem (anterior (ventral) horn cells or certain cranial nerve nuclei), whereas the extrapyramidal system centers on the modulation and regulation (indirect control) of anterior (ventral)

What are signs of akathisia?

Symptoms of akathisia can include: anxiety or agitation. restlessness. feeling emotionally uneasy. dysphoria – feeling bad or depressed. difficulty sleeping. distress or panic attacks. difficulty sitting still; feeling the need to keep moving eg. pacing back and forth. a feeling of wanting to jump out of your skin.

Is tardive dyskinesia serious?

Tardive Dyskinesia. Tardive dyskinesia (TD) is a serious side effect that may occur with certain medications used to treat mental illness. TD may appear as repetitive, jerking movements that occur in the face, neck, and tongue. The symptoms of TD might continue even when the medication is stopped.

Can Seroquel cause EPS?

Quetiapine may increase the blood levels of a hormone called prolactin. Some people may develop muscle related side effects while taking quetiapine. The technical terms for these are “extrapyramidal symptoms” (EPS) and “tardive dyskinesia” (TD). Symptoms of EPS include restlessness, tremor, and stiffness.

Which antipsychotic has the highest incidence of EPS?

The incidence of EPS differs among the SGAs, with risperidone associated with the most and clozapine and quetiapine with the fewest EPS.

How does metoclopramide cause extrapyramidal symptoms?

Metoclopramide can precipitate extrapyramidal symptoms (EPS)/drug-induced movement disorders (DIMD). Tardive dyskinesia and Parkinsonism is generally seen after long-term use, whereas dystonia and akathisia can occur after a single dose of metoclopramide.

Why does metoclopramide cause extrapyramidal symptoms?

Although the possible reason of extrapyramidal side effects presentation is a blockage of striatal D2 receptor, their exact mechanism remains unclear [9]. The most often types of extrapyramidal side effects due to Metoclopramide usage are parkinsonism, tardive dyskinesia, acute dystonias and akathisia.

What is acute dystonia?

Introduction. An acute dystonic reaction is characterized by involuntary contractions of muscles of the extremities, face, neck, abdomen, pelvis, or larynx in either sustained or intermittent patterns that lead to abnormal movements or postures.

What drugs cause drug induced Parkinsonism?

Etiology of Drug-Induced Parkinsonism Antipsychotic drugs. The history of DIP parallels that of antipsychotics. GI motility drugs. GI prokinetic drugs, including metoclopramide, levosulpiride, clebopride, itopride, and domperidone, have also been associated with DIP. Other drugs.

Are extrapyramidal symptoms dangerous?

Extrapyramidal function refers to our motor control and coordination, including being able to not make movements we don’t want to make. Extrapyramidal side effects from medications are serious and may include: Akathisia, which is a feeling of restlessness, making it hard to sit down or hold still.
