Anesthetic.

一般的な説明

Phencyclidine was introduced as a dissociative anestheticfor animals. Its close structural relative ketamine is still soused and may be used in humans. In humans,PCP produces a sense of intoxication, hallucinogenic experiencesnot unlike those produced by the anticholinergic hallucinogens,and often, amnesia.The drug affects many systems, including those of NE,DA, and 5-HT. It has been proposed that PCP (and certainother psychotomimetics) produces a unique pattern of activationof ventral tegumental area dopaminergic neurons.Itblocks glutaminergic N-methyl-D-aspartate receptors.Thisaction is the basis for many of its CNS effects. PCP itself appearsto be the active agent. The psychotic state produced bythis drug is also cited as a better model than amphetaminepsychosis for the psychotic state of schizophrenia.

Special ReportsPCP is predominantly abused by young adults and high school students. In 2010, there was an estimated 53,542 emergency department visits associated with PCP use, according to Drug Abuse Warning Network (New DAWN ED). This is a significant increase from an estimated 37,266 PCP-associated visits in 2008. The American Association of Poison Control Centers (AAPCC) National Poison Data System reports 747 PCP exposure case mentions and 350 single exposures in 2010. According to the 2011 National Survey on Drug Use and Health (NSDUH), 6.1 million (2.4%) individuals in the U.S., aged 12 and older, reported using PCP in their lifetime. The Monitoring the Future (MTF) survey indicates that PCP use among 12th graders in the past year increased from 1.0% in 2010 to 1.3% in 2011 and then decreased to 0.9% in 2012.[US DEADrugs and Chemicals of Concern.

相互作用Nicotine is a widely-abused drug, yet its primary reinforcing effect does not seem potent as other stimulants such as cocaine. Recent research on the contributing factors toward chronic use of nicotine-containing products has implicated the role of reinforcement-enhancing effects of nicotine. The present study investigates whether phencyclidine (PCP) may also possess a reinforcement-enhancement effect and how this may interact with the reinforcement-enhancement effect of nicotine. PCP was tested for two reasons: (1) it produces discrepant results on overall reward, similar to that seen with nicotine and (2) it may elucidate how other compounds may interact with the reinforcement-enhancement of nicotine. Adult male Sprague-Dawley rats were trained to lever press for brief visual stimulus presentations under fixed-ratio (FR) schedules of reinforcement and then were tested with nicotine (0.2 or 0.4 mg/kg) and/or PCP (2.0 mg/kg) over six increasing FR values. A selective increase in active lever-pressing for the visual stimulus with drug treatment was considered evidence of a reinforcement-enhancement effect. PCP and nicotine separately increased active lever pressing for a visual stimulus in a dose-dependent manner and across the different FR schedules. The addition of PCP to nicotine did not increase lever-pressing for the visual stimulus, possibly due to a ceiling effect. The effect of PCP may be driven largely by its locomotor stimulant effects, whereas the effect of nicotine was independent of locomotor stimulation. This dissociation emphasizes that distinct pharmacological properties contribute to the reinforcement-enhancement effects of substances.The aim of the study was to determine the effects of early postnatal PCP treatment on the sensitivity of pubertal and adult rats to lindane proepileptogenic effects. Rat pups were treated with NaCl (0.9%) or PCP (10 mg/kg) at postnatal days 2, 6, 9 and 12. One control (NaCl-35) and one experimental (PCP-35) group have received lindane (4 mg/kg) at postnatal day 35, while others received lindane at postnatal day 65 (NaCl-65 and PCP-65). One week prior to lindane treatment three gold-plated EEG electrodes were implanted. Pubertal rats had significantly shorter latency time. After lindane, a prompt increase in power spectral density seen in PCP-treated groups vs. control was evident earlier in PCP-65 rats. The theta waves were significantly increased in PCP-35 and alpha rhythm in PCP-65 rats, when compared with corresponding controls. Postnatal PCP treatment increases the synchronization of brain electrical activity, thus contributing to the increased susceptibility to lindane.... The combined effects of chronic phencyclidine (PCP) and delta-9-tetrahydrocannabinol on spermatogenesis in mice were examined. Mice were treated with delta-9-tetrahydrocannabinol (50 mg/kg, po) and PCP (15 mg/kg, ip) alone or in combination for 16 days and with PCP alone for 35 days. delta-9-Tetrahydrocannabinol had a significant effect on spermatogenesis and decreased the number of all germinal cells except spermatids after 35 days of treatment. Combination of delta-9-tetrahydrocannabinol and PCP treatment caused a significant decrease in resting and pachytene spermatocytes. Similarly, combination of these two drugs caused a significant increase in cauda epididymal abnormal sperms. These results suggest that delta-9-tetrahydrocannabinol and PCP may cause greater disruption in spermatogenesis when they are abused together.Three non-competitive antagonists (MK-801, TCP, PCP) and one competitive antagonist (CPP) of N-methyl-D-aspartate (NMDA) receptors, were compared for their ability to antagonize neurotoxic actions of NMDA injected into the brains of 7-day-old rats. Unilateral intracerebral injection of NMDA (25 nmol/0.5 microliters) into the corpus striatum of pups consistently produced severe confluent neuronal necrosis in the striatum extending into the dorsal hippocampus and overlying neocortex. The distribution of damage corresponded to the topography of NMDA type glutamate receptors in the vulnerable regions. With this lesion in developing brain, the weight of the injected hemisphere 5 days later can be used as a quantitative measure of brain injury. Intraperitoneal administration of MK-801 (0.02-42.0 umol/kg), TCP (3.5-54.0 umol/kg), PCP (1.0-41.0 umol/kg), and CPP (1.0-60.0 umol/kg) 15 min after NMDA injection had prominent dose-dependent neuroprotective effects. MK-801 was 14 times more potent than other compounds tested and the 50% protective dose (PD50, that dose which reduced damage by 50% relative to untreated NMDA-injected controls) was 0.63 umol/kg. Corresponding values for CPP, PCP, and TCP were 8.84, 10.85, and 24.05 umol/kg respectively. The lowest dose of MK-801 that provided significant protection was 0.2 umol/kg (0.04 mg/kg, 37.9 + or - 4.6% protection). Four umol/kg (0.8 mg/kg) of MK-801 completely protected against NMDA-mediated damage. The study provides the first direct in vivo comparison of the neuroprotective abilities of these compounds. Systemic administrations of MK-801, TCP, PCP, and CPP all limit NMDA-induced neuronal injury in this model. The susceptibility of the immature brain to the neurotoxicity of NMDA provides a sensitive, reproducible, and quantitative in vivo system for comparing the effectiveness of drugs with protective actions against excitotoxic neuronal injury.For more Interactions (Complete) data for Phencyclidine (7 total), please visit the HSDB record page.
HepatotoxicityPhencyclidine is no longer used medically and its production is outlawed. Nevertheless, phencyclidine remains an agent of abuse, used for its hallucinogenic effects. At low doses, phencyclidine appears to have little effect on the liver. However, high doses of phencyclidine have been associated with malignant hyperthermia which can trigger acute hepatitis necrosis and liver failure. Patients generally present with seizures and coma followed by severe hyperthermia, rhabdomyolysis and renal failure. The liver injury arises 1 to 2 days after the overdose with marked, rapid elevations in serum ALT, AST and LDH, with minimal increases in alkaline phosphatase and delayed rises in bilirubin (Case 1). Coma arises early along with prolongation of the prothrombin time, hyperammonemia and metabolic acidosis. The abnormalities resolve almost as rapidly as they develop and with suitable life support, survival is not uncommon (Case 1). The clinical syndrome is that of acute hepatic necrosis and resembles the acute liver injury that occurs with heat shock, severe hypoxia and hepatic ischemia. Liver biopsy shows severe centrilobular necrosis with mild inflammation.
環境中動態TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1300(SRC), determined from a log Kow of 4.69(2) and a regression-derived equation(3), indicates that phencyclidine is expected to have low mobility in soil(SRC). The pKa of phencyclidine is 8.29(2), indicating that this compound will exist almost entirely in cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization from moist soil surfaces is not expected to be an important fate process because this substance exists as a cation and cations do not volatilize(SRC). Phencyclidine is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1.9X10-4 mm Hg at 25 °C(SRC), determined from a fragment constant method(3). Biodegradation data in soil were not available(SRC, 2017).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1300(SRC), determined from a log Kow of 4.69(2) and a regression-derived equation(3), indicates that phencyclidine is expected to adsorb to suspended solids and sediment(SRC). A pKa of 8.29(2) indicates phencyclidine will exist almost entirely in the cation form at pH values of 5 to 9 and, therefore, volatilization from water surfaces is not expected to be an important fate process(SRC). According to a classification scheme(4), an estimated BCF of 580(SRC), from its log Kow(2) and a regression-derived equation(3), suggests the potential for bioconcentration in aquatic organisms is high(SRC). Biodegradation data in water were not available(SRC, 2017).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), phencyclidine, which has an estimated vapor pressure of 1.9X10-4 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase phencyclidine is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be 3.7 hours(SRC), calculated from its rate constant of 1.0X10-10 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Phencyclidine contains chromophores that absorb light at wavelengths up to 269 nm(4) and, therefore, is not expected to be susceptible to direct photolysis by sunlight since sunlight consists of wavelengths above 290 nm(SRC).
Milk ConcentrationsPhencyclidine is concentrated in milk and remains detectable for weeks after heavy use. Breast feeding should be avoided after phencyclidine use, but a sufficient duration of abstinence is undefined.
毒性の概要IDENTIFICATION AND USE: Phencyclidine (PCP) is a white, crystalline powder. It is a Schedule II Controlled Substance. PCP was formerly used as a preinduction anesthetic and as an animal tranquilizer. It has no current medical indications, although it is still used illegally as a hallucinogen. HUMAN STUDIES: PCP causes distortion of perception and produces a feeling of detachment of dissociation from the user's surroundings and self. It is not a classic hallucinogen but better described as a dissociative agent or anesthetic. The hallmark of PCP toxicity is the recurring delusion of superhuman strength and invulnerability resulting from both its anesthetic and dissociative properties. There are case reports of patients presenting with trauma either from jumping from high altitudes, fighting large crowds or the police, or self-mutilation. Children have become intoxicated by ingesting the butts of used PCP-impregnated cigarettes or from passive inhalation of sidestream smoke. Children aged 5 years and younger often present with lethargy, severe depression of consciousness, ataxia, nystagmus, and staring episodes. Presenting signs may also include apnea, seizures, opisthotonos, and choreoathetosis. Miosis may be present. In children, unexplained stupor or coma, seizures, ataxia, nystagmus, strange behavior, staring spells, or unusual posturing can indicate possible PCP intoxication. Patients may present with various combinations of CNS stimulation and depression, cholinergic and anticholinergic effects, and adrenergic effects. The most common physical findings are nystagmus (horizontal, vertical, or rotatory) and hypertension. Respiratory depression and aspiration may also occur. Some patients display evidence of nystagmus, ataxia, loss of muscle coordination, and vital sign abnormalities without obvious signs of behavioral toxicity. Irritability, hypertonicity, poor feeding, and abnormal neurobehavior have been reported in newborns of phencyclidine abusing mothers. ANIMAL STUDIES: Subchronic PCP treatment induces schizophrenic-like behavior in rodents, including cognitive deficits and increased locomotor sensitivity towards acute administration of PCP. Perinatal PCP administration in rat blocks the N-methyl D-aspartate receptor and causes symptoms reminiscent of schizophrenia in human. Animals exposed to PCP during the neonatal period have fewer GABAergic interneurons in the corticolimbic area, including the hippocampus, and exhibit abnormal behaviors after attaining maturation. In developmental studies 25 to 30 mg/kg of PCP was injected into rats on gestational days 6 through 15 and produced skeletal dysplasias and cleft palates in the offspring. Growth retardation and delay in reflexes was found in the offspring of mice exposed to 5 to 20 mg/kg of PCP.
Effluent ConcentrationsPhencyclidine was not detected in waste-water samples collected in October and November 2011 from three major WWTPs in UK serving populations in excess of 100,000 (specific locations not reported)(1).
Soil Adsorption/MobilityThe Koc of phencyclidine is estimated as 1300(SRC), using a log Kow of 4.69(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that phencyclidine is expected to have low mobility in soil. The pKa of phencyclidine is 8.29, indicating that this compound will exist almost entirely in cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).
Human Toxicity Excerpts/HUMAN EXPOSURE STUDIES/ After swallowing a 7.5 mg tablet, /normal volunteers were given a/ battery of /seven/ tests /that were/ repeated every 15 minutes for 2 hr. Phencyclidine produced a general impairment in sensory function as evidenced by the elevated thresholds on all seven tests. Two-point discrimination, aesthesiometry, and perimetry thresholds showed the greatest increase, while taste was the least affected. In addition, the PCP-induced sensory disturbances always occurred before any verbal reports of subjective changes in feelings or mood./SIGNS AND SYMPTOMS/ Nervous system effects include seizures, stupor, coma, cerebral ischemia, subarachnoid hemorrhage, amaurosis fugax, and muscle rigidity. The muscle rigidity, along with agitation, can result in acute rhabdomyolysis and myoglobin-induced renal failure. Myoclonic, choreoathetoid, and dystonic movements, including opisthotonus and torticollis, may be seen./SIGNS AND SYMPTOMS/ PCP causes distortion of perception and produces a feeling of detachment of dissociation from the user's surroundings and self. It is not a classic hallucinogen but better described as a dissociative agent or anesthetic. The most common physical findings are nystagmus and hypertension./SIGNS AND SYMPTOMS/ Most deaths in PCP-intoxicated patients occur because of its behavioral toxicity. The bizarre and violent behavior induced by PCP, along with analgesic effects and lack of muscular coordination, may cause drowning or significant trauma. Nontraumatic causes of death include cardiopulmonary arrest after status epilepticus, primary respiratory arrest, and intracranial hemorrhage.For more Human Toxicity Excerpts (Complete) data for Phencyclidine (25 total), please visit the HSDB record page.
Artificial Pollution SourcesPhencyclidine's production and illicit use as a hallucinogen(1,2) may result in its release to the environment through various waste streams(SRC). This substance is no longer produced or used for medical purposes in the US(1).
Environmental BioconcentrationAn estimated BCF of 580 was calculated in fish for phencyclidine(SRC), using a log Kow of 4.69(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC).
Volatilization from Water/SoilA pKa of 8.29(1) indicates phencyclidine will exist almost entirely in the cation form at pH values of 5 to 9 and, therefore, volatilization from water surfaces is not expected to be an important fate process(SRC). Phencyclidine is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1.9X10-4 mm Hg(SRC), determined from a fragment constant method(2).
