Keeping the thumb on the colored point and with the index fingers close together, apply firm pressure on the colored point in the direction of the arrow to snap the ampule open. The relationship between dose of haloperidol decanoate and plasma haloperidol concentration is roughly linear for doses below mg. What is the most important information I should know about haloperidol Haldol? Dosage adjustments, either upward or downward, should be carried out as rapidly as practicable to achieve optimum therapeutic control. Retrieved 2 January Does Haldol Decanoate 50 Ampul interact with other medications? However, some patients may require treatment despite the presence of the syndrome.
ECG and vital signs should be monitored especially for signs of Q-T prolongation or dysrhythmias and monitoring should continue until the ECG is normal. Should hypotension occur and a vasopressor be required, epinephrine should not be used since HALDOL haloperidol may block its vasopressor activity, and paradoxical further lowering of the blood pressure may occur. Although the long- acting properties of haloperidol decanoate provide gradual withdrawal, it is not known whether gradual withdrawal of antipsychotic drugs will reduce the rate of occurrence of withdrawal emergent neurological signs. Rodents given 2 to 20 times the usual maximum human dose of haloperidol by oral or parenteral routes showed an increase in incidence of resorption, reduced fertility, delayed delivery and pup mortality. Data supporting this finding are very limited. Precautions Before using haloperidol , tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. In a comparison of 15 antipsychotics in schizophrenia, haloperidol demonstrated standard effectiveness.
Given that antagonism of D 2 receptors is more beneficial on the positive symptoms of schizophrenia and antagonism of 5-HT 2 receptors on the negative symptoms, this characteristic underlies haloperidol's greater effect on delusions, hallucinations and other manifestations of psychosis.
Haloperidol acts on these receptors: The drug is well and rapidly absorbed with a high bioavailability when injected intramuscularly. The T max is 20 minutes in healthy individuals and The plasma concentrations of haloperidol decanoate reach a peak at about six days after the injection, falling thereafter, with an approximate half-life of three weeks. The apparent volume of distribution is between 9. If haloperidol is given as a slow IV infusion, the onset of action is slowed, and the duration of action is prolonged.
Plasma levels of four to 25 micrograms per liter are required for therapeutic action. The determination of plasma levels can be used to calculate dose adjustments and to check compliance, particularly in long-term patients.
Plasma levels in excess of the therapeutic range may lead to a higher incidence of side effects or even pose the risk of haloperidol intoxication.
The concentration of haloperidol in brain tissue is about fold higher compared to blood levels. It is slowly eliminated from brain tissue,  which may explain the slow disappearance of side effects when the medication is stopped. Haloperidol is heavily protein bound in human plasma, with a free fraction of only 7. The greatest proportion of the hepatic clearance is by glucuronidation, followed by reduction and CYP-mediated oxidation, primarily by CYP3A4.
Haloperidol was discovered by Paul Janssen. Haloperidol was approved by the U. Haloperidol is also used on many different kinds of animals. It appears to be particularly successful when given to birds, e. From Wikipedia, the free encyclopedia. C Risk not ruled out. S4 Prescription only CA: Aspen Pharma Pty Ltd.

Severe neurotoxicity manifesting as rigidity or inability to walk or talk may occur in patients with thyrotoxicosis also receiving antipsychotics. If administering IV or IM, watch for hypotension; use with caution in diagnosed CNS depression, subcortical brain damage, or cardiac disease; if history of seizures, benefits must outweigh risks; significant increase in body temperature may indicate intolerance to antipsychotics discontinue if this occurs.
Use caution in patients at risk of pneumonia eg, Alzheimer's patients ; antipsychotic use reported to be associated with esophageal dysmotility and aspiration. Extrapyramidal symptoms may occur including acute dystonic reactions, akathisia, tardive dyskinesia, and pseudoparkinsonism; some patients on maintenance treatment experience transient dyskinetic signs after abrupt withdrawal; in certain cases dyskinetic movements are indistinguishable from tardive dyskinesia except for duration; not known whether gradual withdrawal will reduce rate of occurrence of withdrawal emergent neurological signs but until further evidence becomes available, gradually withdraw therapy.
Motor instability, somnolence, and orthostatic hypotension reported, which may lead to falls and, consequently, fractures or other fall-related injuries; assess risk of falls when initiating treatment and recurrently for patients receiving repeated doses, particularly the elderly, with diseases, conditions, or medications that could exacerbate these effects.
Impairment of core body temperature regulation reported; use caution with activities that may increase body temperature including strenuous exercise, heat exposure, dehydration, and concomitant medications with anticholinergic effects. Caution in patients receiving anticoagulants; isolated instance of interference occurred with effects of one anticoagulant phenindione. May cause anticholinergic effects; use caution in patients with xerostomia, urinary retention, BPH, decreased gastrointestinal motility, paralytic ileus, or visual problems.
Decreased sensation of thirst due to central inhibition may lead to dehydration, hemoconcentration and reduced pulmonary ventilation; a number of cases of bronchopneumonia, some fatal, reported; if signs and symptoms appear, especially in the elderly, institute remedial therapy promptly. Use caution in patients receiving anticonvulsant medications, with a history of seizures, or with EEG abnormalities; haloperidol may lower convulsive threshold; if indicated, adequate anticonvulsant therapy should be concomitantly maintained.
C; neonates exposed to antipsychotic drugs during 3rd trimester of pregnancy are at risk for extrapyramidal or withdrawal symptoms after delivery; these complications vary in severity, in some cases being self-limited and in other cases necessitating ICU support and prolonged hospitalization. Controlled studies in pregnant women show no evidence of fetal risk.
Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. Use with caution if benefits outweigh risks.
Animal studies show risk and human studies not available or neither animal nor human studies done. Positive evidence of human fetal risk. Do not use in pregnancy. Risks involved outweigh potential benefits. Phenylbutylpiperadine; antagonizes dopamine D1 and D2 receptors in brain; depresses reticular activating system and inhibits release of hypothalamic and hypophyseal hormones.
Haloperidol lactate and haloperidol decanoate are both administered IM; haloperidol lactate has also been administered IV off-label ; haloperidol decanoate should not be administered IV.
