The patient was treated with benzodiazepines and cooled IV fluids in order to manage the hyperpyrexia and other features of toxicity that he had developed. He was also treated initially with broad-spectrum antibiotics to cover for possible sepsis as would be expected in a case where initially the diagnosis is unclear. When the history revealed that our patient had indeed used both 3-HO-PCP and N-ethylhexedrone, the physicians managing his care discontinued antibiotic treatment with the knowledge that infection was no longer to cause for his hyperthermia. Following treatment, the patient made a full recovery allowing him to be discharged from the hospital the following day. 3-Hydroxyphencyclidine (3-HO-PCP) is a new psychoactive substance (NPS) and a hydroxy derivative of phencyclidine (PCP), and N-ethylhexedrone (Hexen) is a synthetic cathinone. We describe an analytically confirmed case of acute toxicity related to the use of both 3-hydroxyphencyclidine and N-ethylhexedrone.
- Patient should be followed up for at least 2-3 days, as dystonia caused by long acting drugs may cause relapse of dystonia.
- Support groups provide a community-based approach for recovering addicts, creating shared experiences and accountability.
- The reason for the time difference is how fast the substance enters your bloodstream.
- Its half-life ranges from 7-46 h but may be prolonged in chronic users owing to redistribution from adipose tissue.1-4,6 Severe respiratory failure, AH and ARDS are rare complications, with only a few cases reported in the literature.
- For ED personnel in metropolitan areas with high rates of illicit drug use, heightened awareness of the reemergence of PCP may be especially useful for assessing patients who present with violent or suicidal behavior.
- The description of the acute toxicity of NPS, such as these, is vital to aid medical toxicologists and emergency medicine physicians treating patients who use them.
Originally phencyclidine intoxication andadverse effects: a clinical and pharmacologicalreview of an illicit drug pmc developed as an anesthetic, it was withdrawn from medical use due to psychosis and agitation post-surgery. PCP remains a drug of abuse and is often encountered in PCP-laced products, particularly marijuana. The drug exhibits complex pharmacokinetics and can lead to varying clinical manifestations ranging from agitation to respiratory depression, culminating in severe behaviors and potentially fatal outcomes. Understanding its neuropharmacological properties and clinical implications is crucial for effective management in cases of intoxication.
Status epilepticus should be treated with airwayprotection and IV benzodiazepines orphenobarbital. Benzodiazepinesare a useful adjunct to prevent shivering andprovide sedation. As with all intoxications, a blood glucosemeasurement should be obtained, and 100 mgthiamine and dextrose 50% should be administeredif the blood sugar is abnormally low.

- PCP can cause acute changes in vital signs such as blood pressure and body temperature, contributing to the overall state of the user during intoxication.
- At high doses, PCP can lead to rhabdomyolysis, hypoglycemia, seizures, and coma.
- While briefly showing promise as being the “ultimate” anasthetic agent during the late 1950s, it very quickly fell into disfavor because of untoward side-effects during post-anesthetic emergence (1960s).
- A 25-year-old man with the past medical history of marijuana use presented to ED with involuntary upward deviation of eye 1 day after using phencyclidine (PCP) for the first time.
Clinical examination revealed ecchymosis and swelling of the upper arm and forearm, no palpable pulses at the level of the wrist and hand was cold. Unfortunately patients developed multiorgan failure, respiratory failure, renal failure, shock liver, cardiogenic shock and passed on day 6th of hospitalization (Table 1). Patients intoxicated with phencyclidine (PCP) present both diagnostic and management dilemmas. The clinical presentation ranges from coma to severe agitation and violence; disorientation, psychosis, catatonia and bizarre behavior can be seen. Patients are at-risk for significant medical complications such as rhabdomyolysis, seizures, and hyperthermia.

According to one 2007 review, these symptoms often begin around 8 hours after discontinuation and may last several weeks or months, depending on the duration and frequency of PCP use. Outpatient therapy may also be an option for those who require more flexibility. These programs involve participating in individual or group therapy sessions during the day and returning home after each session. PCP’s effects generally last from 6 to 24 hours but linger up to around 48 hours in some people. In people with more body fat, effects can come and go or fluctuate over a few days to months. If you ingest it orally, the effects take longer to kick in — usually 30 to 60 minutes.
How is PCP addiction treated?
Both of these individuals were in drug rehabilitation facilities prior to their deaths; however, users continue to be drawn to 3-MeO-PCP due to its dissociative effects and its accessibility on the internet. As a non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist, PCP is a dissociative anesthetic. PCP intoxication has no specific antidote; management is primarily supportive. PCP-induced agitation and delirium are primarily managed with benzodiazepines.1,3-6 PCP intoxication predominantly affects males aged years and is a common cause of ED visits due to violent behavior and acute psychosis. The leading causes of PCP-related mortality include cardiac arrest, trauma, and hyperthermia. PCP is highly lipophilic and protein-bound and undergoes hepatic metabolism, with 9% excreted unchanged in the urine.
How is PCP used?
PCP users were more likely to be of minority status, but not younger, than comparison participants. PCP use was relatively rare and occurred almost exclusively in the context of polysubstance abuse in the sample of offenders court referred for substance use evaluations. Nearly 75% of all PUD participants were concurrently diagnosed with a cannabis use disorder. Also among the most commonly co-occurring substances of abuse was alcohol, which was abused by more than half of the PUD participants. Given the comorbid substance use disorders and violent behavior observed in PCP users, it is not surprising that PCP diagnosed participants received recommendations for higher levels of care than comparison participants. By recognizing the signs and symptoms of PCP intoxication, health care providers—especially those on the front lines of emergency care—can help to ensure that patients who come into medical facilities receive immediate and appropriate care.

Acute dystonia is a movement disorder characterized by intermittent or sustained involuntary muscle contractions involving face, pelvis, trunk, neck, or rarely larynx 6. Oculogyric crisis is a type of acute dystonia characterized by spasmodic movement of eyeball, usually upward, and each spasm lasts from seconds to hours. Oculogyric crisis is not usually life threatening but it can be very distressing to the patient and family.
History and Cultural Significance
Oculogyric crisis is a form of acute dystonic reaction characterized by involuntary upward deviation of eye ball. Its causes are broad with antipsychotics and antiemetics as the most common causes. A 25-year-old man with the past medical history of marijuana use presented to ED with involuntary upward deviation of eye 1 day after using phencyclidine (PCP) for the first time. All laboratory investigations were normal except urine drug screen which was positive for PCP. Illicit drug abuse is a growing problem in our society with increasingly more patients presenting to ED with its complications. The differential diagnosis of acute dystonic reactions should be extended to include illicit drugs as the potential cause of reversible acute dystonias especially in high risk patients.
Though it was briefly used in humans, it was soon discontinued due to its psychological and behavioral side effects. Long-term or chronic use of dissociative drugs like PCP may also cause speech difficulties, memory loss, suicidal thoughts, social withdrawal, and anxiety. According to the National Institute on Drug Abuse, repeated use can lead to tolerance and the development of a substance use disorder, including withdrawal symptoms when you stop taking it.
