What are the most common medications associated with EPS?
Centrally-acting, dopamine-receptor blocking agents, namely the first-generation antipsychotics haloperidol and phenothiazine neuroleptics, are the most common medications associated with EPS. While EPS occurs less frequently with atypical antipsychotics, the risk of EPS increases with dose escalation.[3] Other agents that block central dopaminergic receptors have also been identified as causative of EPS, including antiemetics (metoclopramide, droperidol, and prochlorperazine),[4][5]lithium,[6]serotonin reuptake inhibitors (SSRIs),[7]stimulants,[8]and tricyclic antidepressants (TCAs).[7] In rare situations, antivirals, antiarrhythmics, and valproic acid have also been implicated.

How to reduce EPS?
If the EPS are induced by an antipsychotic, EPS may be reduced by decreasing the dose of the antipsychotic or by switching from a typical antipsychotic to an (or to a different) atypical antipsychotic, such as aripiprazole, ziprasidone, quetiapine, olanzapine, risperidone, or clozapine.

What is EPS in a drug?
Extrapyramidal Symptoms (EPS) are drug-induced movement disorders that occur due to antipsychotic blockade of the nigrostriatal dopamine tracts. These blockades can lead to increased cholinergic activity, resulting in acute dystonia, acute akathisia, antipsychotic-induced parkinsonism, tardive dyskinesia (TD), tardive dystonia, and tardive akathisia.
How to detect tardive dyskinesia?
Tardive dyskinesia movements can often be revealed or amplified by an activation technique since many patients need to be distracted before the disorder will visually manifest. For example, ask the patient to keep their mouth open for 20 to 30 seconds, then ask them hold up their hand while tapping each finger to the thumb in sequence. Another clinical exam is to ask the patient to open and close each hand while the mouth is open. This allows one to observe any curling or writhing movements of the tongue. [20] TD can persist even after discontinuing treatment, hence, it is very important to monitor for early signs of TD using the Abnormal Involuntary Movement Scale (AIMS) .
What are the symptoms of Parkinson's disease?
Symptoms are similar to Parkinson's Disease, including bradykinesia, mask-like face, cogwheel rigidity, and tremors. Tremors are considered a cardinal sign of antipsychotic-induced Parkinsonism. [15] Other features of drug-induced parkinsonism include increased salivation, drooling, seborrhea, and postural instability. Approximately 40% of older patients treated with typical antipsychotics can develop drug-induced parkinsonism even at low doses. [16] Atypical antipsychotics have a lower incidence of causing parkinsonism.

Causes
Diagnosis
Classification
Extrapyramidal symptoms (EPS) are symptoms that are archetypically associated with the extrapyramidal system of the brain's cerebral cortex. When such symptoms are caused by medications or other drugs, they are also known as extrapyramidal side effects (EPSE). The symptoms can be acute (short-term) or chronic (long-term). They include movement dysfunction such as dystonia (continuous spasms and muscle contractions), akathisia (may manifest as moto…
Treatment
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. Atypical antipsychotics have lower D2 receptor affinity or higher serotonin 5-HT2A receptor affinity which lead to lower rates of EPS.
