healthy volunteers: 50 - 150 mg. administration route is not specified.

Route of Administration: Unknown

In Vitro Use Guide

In vitro studies of rat cuneate nucleus indicated that the proconvulsant actions of PK 8165 could be explained by its direct, albeit slightly different, interactions with the GABA-receptor complex. PK 8165 (100 microM) alone had no effect on responses to the GABA analogue muscimol, but enhanced the potency of picrotoxin as an antagonist of muscimol and reduced the potency of flurazepam as a potentiator of muscimol.
