  BioMed Central | Full text | Use of neuroleptics in a general hospital
Neuroleptic drugs are commonly prescribed in acutely ill-hospitalised patients [1-3].
Neuroleptic drugs are commonly prescribed to treat agitation or delirious states in acutely ill hospitalised patients [1,3].
As neuroleptics are not innocuous drugs,[28] physicians must recognize that these drugs can promote important side effects, and prior investigators have demonstrated than physicians often lack sufficient knowledge about the therapeutic use and pharmacokinetis of these medications.

 WE MOVE - Treatment of Pediatric Movement Disorders - Medication: Neuroleptics
Neuroleptics are a class of medications that were originally developed to treat psychosis.
In particular, all neuroleptics, with the exception (thus far) of clozapine have been reported to induce parkinsonism and tardive symptoms, including tardive dyskinesia and tardive dystonia.
Neuroleptic malignant syndrome, characterized by confusion, stiffening of the muscles, high temperature, and elevated muscle enzymes in the blood, is a rare, potentially life-threatening complication of neuroleptic treatment.

 p000216b - Neuroleptic Malignant Syndrome - Treatment
The neuroleptic malignant syndrome was initially described as a disorder specifically related to neuroleptic usage with frequent fatal outcome.
The observations of variant or mild cases of this syndrome as well as case reports on neuroleptic-malignant-like syndromes in the absence of neuroleptics raises the issue of the usefulness of this terminology and highlights the potential for inappropriate management of this "malignant" syndrome.
Out treatment strategy is based on the pharmacology of neuroleptics and empirical data, verified in our own clinical practice and considers that it is often difficult to determine whether certain physiologic states are a consequence to or specific triggering factors.

 Neuroleptics, psychiatric drug hazards and tardive dyskinesia by Peter R. Breggin, MD
The neuroleptics are supposedly most effective in treating the acute phase of schizophrenia, but a recent definitive review of controlled studies showed that they perform no better than sedatives or narcotics and even no better than placebo (Keck et al., 1989).
That the neuroleptics emptied the U.S. mental hospitals is a myth.
Beyond the specific issue of the neuroleptics, there is a much broader one— how are we to understand and to show care for people who undergo emotional pain and anguish (Breggin, 1991,1992; Mosher and Burti, 1989).

 Bipolar Disorder: Encyclopedia of Medicine
Because the drug takes four to ten days to reach a therapeutic level in the bloodstream, it is sometimes prescribed in conjunction with neuroleptics and/or benzodiazepines to provide more immediate relief of a manic episode.
Neuroleptics such as chlorpromazine (Thorazine) and haloperidol (Haldol) are also used to control mania while a mood stabilizer such as lithium or valproate takes effect.
Because neuroleptic side effects can be severe (difficulty in speaking or swallowing, paralysis of the eyes, loss of balance control, muscle spasms, severe restlessness, stiffness of arms and legs, tremors in fingers and hands, twisting movements of body, and weakness of arms and legs), benzodiazepines are generally preferred over neuroleptics.

 [No title]
The term neuroleptic refers to the theory that these medications “take control of the neuron,” which is supported by their positive affects on psychotic disorders and their extrapyramidal side effects.
In early treatment with neuroleptics, it was thought that their infrequent or intermittent use as an episodic cure (to be used when the psychosis “flared up”) would be effective in treating the psychosis and minimize the risk of acquiring TD.
TD suppression by neuroleptics works extraordinarily well in the short term and as a relief from withdrawal-emergent TD, but both Jeste and Egan caution that it is unsound to use the same substance that is causing TD to treat it.

These novel neuroleptics display a complex pharmacological profile with affinities for several receptor systems but are generally characterized by a greater affinity for the 5-HT2A receptor than for the target of the traditional neuroleptics, the D2 receptor [4,5].
Both neuroleptics decreased the EMG during phase 2, where high frequency oscillations occur in the bladder pressure along with bursting in the EUS, with the highest dose of olanzapine (1.0 mg/kg) abolishing the HFO and the bursting pattern.
Finally, neither neuroleptic decreased the amplitude of the individual bursts of EMG recorded during phase 2, except for the largest dose of olanzapine (1 mg/kg) that abolished the bursting pattern.

Neuroleptics are used mainly to treat psychosis but are prescribed, often inappropriately, to treat agitated behavior in demented or mentally retarded patients, who are particularly susceptible to neuroleptic side-effects.
Highpotency neuroleptics, such as haloperiidol and fluphenazine, are most likely to cause extrapyramidal side-effects, but are less sedating, have less anticholinergic side-effects and cause less orthostatic hypotension than low-potency neuroleptics such as chlorpromazine or thioridazine, which have side-effect profiles that are the inverse of the high-potency neuroleptics.
Every patient who is prescribed a neuroleptic should have a formal examination for TD, such as the AIMS scale, before initiation of the neuroleptic and every 3 months thereafter that the patient remains on the drug.

Neuroleptic medications diminish psychotic symptoms, including hallucinations, delusions, and disorganization of thought in most patients.
Neuroleptic dose reductions should proceed in an orderly fashion with frequent monitoring of symptoms.
Neuroleptic-induced side effects can be managed by switching neuroleptics or adding medication to reverse the side effect; for example, patients who develop muscular stiffness, i.e., drug-induced parkinsonism, on Haldol or risperidone can receive low doses of Cogentin (0.5-1.0 mg BID) to reverse the drug-induced parkinsonism.

 Psychiatric Drugs: Neuroleptics, The Effects of Haldol, Prolixin, Thorazine, Mellaril, and Other Antipsychotic Drugs
Neuroleptic was coined by jean Delay and Pierre Deniker, who first used the drug in psychiatry, and means "attaching to the neuron." Delay and Deniker intended the term to underscore the toxic impact of the drug on nerve cells (see chapter 4).
The neuroleptics are the most frequently prescribed drugs in mental hospitals, and they are widely used as well in board-and-care homes, nursing homes, institutions for people with mental retardation, children's facilities, and prisons.
The neuroleptics also are used in tranquilizer darts for subduing wild animals and in injections to permit the handling of domestic animals who become vicious.

 Neuroleptics and Neurotoxicity
I think that when people seems to respond to neuroleptics, that maybe their brains are sensitive to excess dopamine and the neuroleptics produce a paradoxical effect and suppress dopamine, thus covering up symptoms.
It has occurred to me that these neuroleptics may be causing the "mental illnesses" in patients by disrupting the neurotransmitter system, and that maybe Dilantin and Centrax in a cocktail dose could help them the way it helped me. Also the SSRI's can cause the same neuroleptic effects, as I found to my detriment.

Antipsychotics are also referred to as neuroleptic drugs, or simply neuroleptics.
Users typically take smaller doses during the day for the neuroleptic properties and larger dose at bedtime for the sedative effects, or divided in two equally high doses every 12 hours (75-400mg bid).
Another serious side effect is neuroleptic malignant syndrome, in which the drugs appear to cause the temperature regulation centers to fail, resulting in a medical emergency as the patient's temperature suddenly increases to dangerous levels.

In 1963, the NIMH reported that neuroleptics were better than placebo over a six-week period in reducing psychosis, a study that is still cited today as showing the drugs' efficacy.
As the Canadian investigators concluded: "Some patients who seem to require lifelong neuroleptics may actually do so because of this therapy." This finding has particular relevance for the sub-group of patients, 40% or more, who had done well in the trials in which they were treated with psychosocial care.
They may not have naturally needed neuroleptics, but once they were exposed to the drugs, they would likely find it difficult to get off them, and thus would be pushed along a path that involved lifelong medication, with all its associated problems.

 The Effects of Neuroleptics on Plasma Homovanillic Acid
Neuroleptics are potent D2 antagonists, blocking signal transduction to postsynaptic D2 receptors, and interfering with the sensing function of presynaptic D2 receptors (for review, see ref.
The high concentration of dopamine impinging on the blocked postsynaptic receptors competes with the neuroleptic for the binding site; however, the neuroleptic antagonist has a much higher affinity than dopamine for the postsynaptic D2 receptor and thus is probably only minimally displaced.
Neuroleptic drugs, which are D2 antagonists, increase tremor amplitude and slow its frequency.
