Etoxadrol is a dioxolane NMDA antagonist developed as a dissociative anesthetic; unlike arylcyclohexylamines (PCP/ketamine), it features a 1,3-dioxolane piperidine scaffold. Clinical work shows IV 0.75 mg/kg yields anesthesia averaging 26 minutes (14-53 minutes) with active airway reflexes but raised heart rate/blood pressure and tachypnea. Prominent post-dose phenomena include alternating nystagmus lasting hours and vivid dream-like states; approximately 20% of patients reported unpleasant or threatening dreams persisting up to 24 hours. One overdose case at 4.65 mg/kg caused catalepsy, amnesia, and analgesia lasting 6 days. Binding studies place etoxadrol as a high-affinity PCP-site channel blocker at NMDA receptors (Ki = 107 nM), explaining PCP-like behavioral effects and animal self-administration.
