Methoxphenidine, a novel dissociative designer drug of the diarylethylamine class with structural features similar to phencyclidine (PCP), produced PCP-like adverse effects in a 53-year-old man found on the street in a somnolent and confusional state. Observed signs included tachycardia (112 bpm), hypertension (220/125 mmHg), echolalia, confusion, agitation, opisthotonus, nystagmus, and amnesia. Temperature and oxygen saturation were normal. Laboratory findings showed elevated creatine kinase (max 865 U/L), alanine aminotransferase (72 U/L), and gamma-glutamyl transpeptidase (123 U/L). Methoxphenidine was confirmed in plasma and urine via liquid chromatography tandem mass spectrometry. The patient recovered with symptomatic treatment.
