How to treat haloperidol toxicity?
Since there is no specific antidote, supportive treatment is the mainstay of haloperidol toxicity. If a patient develops signs and symptoms of toxicities, the clinician should consider gastric lavage or induction of emesis as soon as possible, followed by the administration of activated charcoal. Maintenance of Airway, Breathing, and circulation are critical factors for survival. A patent airway is ensured by using an oropharyngeal airway or endotracheal tube. Comatose patients with a difficult airway or upper airway obstruction require a tracheostomy. Supplemental oxygen is administered via nasal prongs or facemask. Patients with refractory hypoxia often require intubation and mechanical ventilation.

How is haloperidol released?
Haloperidol's production and use as an antidyskinetic and an antipsychotic may result in its release to the environment through various waste streams. If released to air, an estimated vapor pressure of 4.85 × 10−11 mmHg at 25 °C indicates haloperidol will exist solely in the particulate phase in the ambient atmosphere. Particulate-phase haloperidol will be removed from the atmosphere by wet and dry deposition. If released to soil, haloperidol is expected to have no mobility based on an estimated Koc of 5200. Volatilization from moist soil surfaces is not expected to be an important fate process based on an estimated Henry's law constant of 2.3 × 10 −14 atm m 3 mol −1. The p Ka of haloperidol is 8.66, indicating that this compound will exist primarily in the protonated form in the environment, and cations generally adsorb more strongly to organic carbon and clay than their neutral counterparts. If released into water, haloperidol is expected to adsorb to suspended solids and sediment based on the estimated Koc. Volatilization from water surfaces is not expected to be an important fate process based on this compound's estimated Henry's law constant. Haloperidol will exist almost entirely in the ionized form at pH values of 5–9, and therefore volatilization from water surfaces is not expected to be an important fate process. An estimated bioconcentration factor of 59 suggests the potential for bioconcentration in aquatic organisms is moderate. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions. Occupational exposure to haloperidol may occur through dermal contact with this compound at workplaces where haloperidol is produced or used. Users of haloperidol can be exposed through intravenous injection or oral consumption (tablets and liquid).
What happens if haloperidol is released into water?
If released into water, haloperidol is expected to adsorb to suspended solids and sediment based on the estimated Koc. Volatilization from water surfaces is not expected to be an important fate process based on this compound's estimated Henry's law constant.

How to treat rapid tranquilization?
Treatment choice for rapid tranquilization is dependent on a number of factors, including the patient’s presentation, the availability of drugs in a certain setting and the desired effect. The therapeutic endpoint of rapid tranquilization is a matter of debate and in clinical practice, three different approaches are common [2-3]. Certain clinicians consider it best to sedate the patient completely and prefer to increase the dosage of the drug until the patient is asleep. Others may opt for lighter sedation, which retains the patient’s ability to communicate. The final approach, which is also the most suitable for contemporary clinical practice, is to administer drugs at the lowest possible dose which calms the patient and leads to resolution of behavioral symptoms, if possible without inducing sedation or sleep [2-3]. If the initial tranquilization regimen is successful, the patient can be followed up with a regular psychiatric assessment [2-3]. Accounting for the fact that not all available drugs are conducive to all of the aforementioned treatment goals, it becomes obvious that deciding upon which drug to use and at what dosage should be influenced primarily by the stated purpose of the treatment. Suitable drugs include typical antipsychotics (often co-administered with an anticholinergic agent to reduce the incidence of side effects [4], benzodiazepines and, most recently, atypical antipsychotic drugs.
What is the treatment for agitation?
The practice of treating agitation on an acute care basis is also referred to as rapid tranquilization. A variety of psychotropic drugs and combinations thereof can be used. The decision is usually made based on availability and the clinician’s experience, with the typical antipsychotic haloperidol (alone or in combination with antihistaminergic and anticholinergic drugs such as promethazine), the benzodiazepines lorazepam, diazepam and midazolam as well as a variety of atypical antipsychotics being used for this purpose. Haloperidol is associated with extrapyramidal symptoms (which can be controlled by co-administration of promethazine) and may control agitation without inducing sedation, while benzodiazepines have a more pronounced sedating activity. The atypical antipsychotics aripiprazole and ziprasidone are better tolerated, while olanzapine is also a powerful sedative. Clinical trials evaluating the efficacy of different treatment options have been conducted but they are extremely heterogenous and most have numerous methodological flaws, leading to a poor overall quality of evidence upon which guidelines for the appropriate treatment could be based. The combination of haloperidol and promethazine, which combines the sedative properties of the antihistamine with the more selective calming action of haloperidol (with a reduced risk of extrapyramidal effects compared to haloperidol alone because of the anticholinergic properties of promethazine) may be the best choice based on empirical evidence.
Why do people use benzodiazepines?
Benzodiazepine use in the context of rapid tranquilization generally has the goal of calming the patient and ensuring adherence to follow- up treatment. Excessive sedation is generally regarded as an undesirable effect. Compared with antipsychotics such as haloperidol, benzodiazepines pose a far greater risk to the patient as they may cause respiratory depression in high doses, and may also contribute to dangerous drug interactions with other depressants which the patient may have been exposed to [23]. The risk of interactions is much greater when the patient presents to the emergency department with acute agitation, as his previous history is unknown and in many cases unobtainable until the situation is resolved, and for this reason drugs such as ketamine with a lower propensity for such interaction are preferred in the ER setting [24].
Is haloperidol dose dependent?
The drug saturates D2 receptors even at very low dosages, thus its effects are not dose-dependent [9].
Is haloperidol a selective drug?
It is by no means selective and may also bind to other receptors in the central nervous system (CNS), including a1 adrenergic and sigma receptors [5]. Its effects have been thoroughly documented in the literature. It is available both in oral and parenteral formulations (designed for intramuscular (IM) administration, though intravenous (IV) administration is also possible). When administered orally, the effects are noticeable within an hour, while 10-15 minutes are required for the onset of action after IM administration. For this reason, the IM route is preferred in the setting of rapid tranquilization [6].
