Akathisia is generally associated with antipsychotics, but was previously described in Parkinson's disease and other neuropsychiatric disorders. [5] It can also present with the use of non-psychiatric medications, including calcium channel blockers , antibiotics , anti-nausea and anti-vertigo drugs .
Extrapyramidal symptoms are most commonly caused by typical antipsychotic drugs that antagonize dopamine D2 receptors. [2] The most common typical antipsychotics associated with EPS are haloperidol and fluphenazine. [4] Atypical antipsychotics have lower D2 receptor affinity or higher serotonin 5-HT2A receptor affinity which lead to lower rates ...
Use of high-potency antipsychotics, a rapid increase in the dosage of antipsychotics, use of long-acting forms of antipsychotics (such as haloperidol) or injectable formulations, or using multiple antipsychotics are all known to increase the risk of developing NMS. [20] [21] [7] Dehydration is a risk factor for the development of NMS. [7]
Antipsychotics, previously known as neuroleptics [1] and major tranquilizers, [2] are a class of psychotropic medication primarily used to manage psychosis (including delusions, hallucinations, paranoia or disordered thought), principally in schizophrenia but also in a range of other psychotic disorders.
In other cases, psychomotor agitation can be caused by antipsychotic medications. For instance, akathisia, a movement disorder sometimes induced by antipsychotics and other psychotropics, is estimated to affect 15-35% of patients with schizophrenia. [11] [12]

Late-onset dyskinesia, also known as tardive dyskinesia, occurs after long-term treatment with an antipsychotic drug such as haloperidol (Haldol) or amoxapine (Asendin). The symptoms include tremors and writhing movements of the body and limbs, and abnormal movements in the face, mouth, and tongue – including involuntary lip smacking, repetitive pouting of the lips, and tongue protrusions.
Pleurothotonus, commonly known as Pisa syndrome, is a rare neurological disorder which occurs due to prolonged exposure to antipsychotic drugs (which may also be referred to as neuroleptics). It is characterized by dystonia, and abnormal and sustained involuntary muscle contraction. This may cause twisting or jerking movements of the body or a ...
