โฆ Synopsis
Phencyclidine hydrochloride (PCP), injected subcutaneously into rats 30 rain before exposure to the chemical convulsant flurothyl, raised seizure thresholds in a doserelated manner. The narcotic antagonist naloxone was ineffective in blocking the PCP-induced effect. This anticonvulsant property of PCP is like that previously reported for the narcotic agonist-antagonists cyclazocine and SKF 10,047 (N-allylnormetazocine), which also resemble PCP in their ability to induce psychotomimetic behavior. The data support the idea that these three drugs act on the same receptors.

The present study was designed to examine the ability of felbamate, a novel antiepileptic agent, to antagonize the increase in seizure severity (i.e., chemical kindling) produced by chronic treatment with initially subconvulsant doses of pentylenetetrazol (PTZ).
