Key Takeaways
- Phencyclidine (PCP) has the chemical formula C17H25N and a molecular weight of 243.4 g/mol.
- PCP is structurally similar to ketamine and acts as an NMDA receptor antagonist with Ki = 62 nM.
- The melting point of pure PCP hydrochloride is 223-226°C.
- Low doses of PCP (1-5 mg) produce analgesia and sedation lasting 4-6 hours.
- At 5-10 mg doses, PCP induces euphoria, distorted perceptions, and detachment from reality.
- High doses (>10 mg) of PCP cause catatonia, nystagmus, and blank stare in 50% of users.
- In 2020, 12,000 past-year PCP users aged 12+ were reported in the US NSDUH survey.
- Lifetime PCP use prevalence among US adults is 2.9% per 2019 NSDUH.
- PCP was involved in 1.2% of drug-related ER visits in 2011 DAWN data.
- PCP is classified as a Schedule II controlled substance under US CSA since 1978.
- First synthesized in 1926 by Parke-Davis as anesthetic Sernyl.
- PCP was marketed as Sernyl for anesthesia until 1965 due to neurotoxicity.
- Oral bioavailability of PCP is nearly 100% due to its lipophilic nature.
- Peak plasma concentrations of PCP occur 1-3 hours after oral ingestion of 10 mg.
- Elimination half-life of PCP ranges from 11-53 hours, averaging 21 hours.
PCP is a fast acting NMDA antagonist with high lipophilicity, common emergency presentations, and rising risk of severe toxicity.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
